3 - nozzle
The Fire since ancient served people for cooking. Stone pores The home focus has undergone many changes. Today we will talk about gas stoves. What are they enhanced modern foci? What kind of metamorphosis happened to them in recent years?
Attention! We will tell in this article precisely about gas plates, and not about cooking panels and ovens. But you must first figure out what is meant by the concept of "stove". Often, this definition is applied to a separate cooking surface, and to the design, in which the oven is hidden under the panel. In fact, the stove is a cooking panel and an oven in a single case. Iikikov otherwise. Gaza privilege
Pros and cons of gas plates
1. There are no special requirements for dishes (for example, the bottom can be curved).
2. Cheapness.
3. Easily adjust the degree of heating.
4. Many prefer food cooked on open fire.
Minuses
1. It is necessary to monitor the safety and cleanness of air in the kitchen.
2. It is difficult to clean than electrical.
3. The layers of the dishes can be mounted.
Modern norms provide for the opportunity to bring gas pipeline only to buildings that are below 11 floors. If we talk about private country houses, then here you are, of course, the owners themselves and you can buy a plate and cylinders with gas to her in addition. But then other restrictions should be taken into account, which, however, concern and urban apartments. The standards are allowed to install gas equipment indoors with a ceiling height of at least 2.2m, having a window with a window, exhaust ventilation channel and natural lighting. Auto kitchen volume should be at least 8m3 for plates with two burners and 15m3- for a plate with four burners.
But if your apartment meets all the requirements, you can feel the main advantage of gas - low cost, because on average, the "work" of the gas stove is cheaper than electric 10 times. I would like to note that there are no special diversity in the gases of gas plates. Usually their height is 85cm, as well as standard kitchen furniture. The width is 50-90cm, the depth is 50-60cm.
Straight into the heart
"Heart" of a gas stove - gas burners. The versatility of your stove depends on their power and quantity. The burners can be 2-6, and often they differ in power: small - about 1 kW, nominal - 1.75-2 kW, elevated - 2.7-2.9 kW. The optimal option: two torches of rated power, one - elevated and one - small. By the way, the efficiency of gas burners is at least 58%, that is, precisely such part of the heat of the burner is able to "pass" the dishes. The rest goes on unnecessary heating of the room.
Device and burner
The fuel burner in a certain proportion is mixed with air and gas. The mixture can ignite (that is, the gas is on) if the "gas-air" ratio is in a certain range (its lower bound - 5.3% - "poor" mixture, and the upper - 14.2% - "rich" mixture) and , of course, if I spark.
The design of the burner should provide high combustion efficiency with low toxic substances, when in combustion products - no more than 0.01% in volume, or 125 mg / m3, carbon monoxide (carbon monoxide) and no more than 200 mg / m3 nitrogen oxides.
The surface of the plates can be covered with enamel - ZCG569GW1 (Zanussi, Italy), made of polished stainless steel - EKK 601302 X (Electrolux, Sweden), C 640 G6 White (Ardo, Italy) or from glass ceramics - CM 64220 (Beko, Turkey). Enamel is tested by time, it is famous for wear resistance, it is not terrible organic acids and sugar. However, in time, chips can appear on it. The coating of polished stainless steel is more expensive, but it looks more effectively. In addition, the undoubted plus is that steel is almost impossible to scratch, although the traces of fingers on it are very noticeable. The glass-ceramic surface is pretty light in cleaning, but the sweet liquid is destructive for it. Once so strenuously advertised "gas under glass" is now on sale.
It is no secret that in our country, gas pressure jumps in networks often occur. How do the slabs react to such whims? In accordance with Russian norms, gas stoves should be stable to operate when the gas pressure changes from 650 to 1800 Pa at rated pressure in the network 1300 Pa. That is, as you can see, the plates are designed for a sufficiently large range of gas pressure.
What's new?
1 - gas burner;
2 - oven grille;
3 - baking tray;
4 - burner of the brass cabinet;
5 - compartment for kitchen utensils;
6 - control panel;
7 - panel grille;
8 - the plate cover of one side, the principle of operation of modern gas stoves is the same as predecessors. But on the other, it is impossible to compare them, since for years for 20 plates changed beyond recognition. The most important problem is to ensure security. Therefore, when modernizing the plates, attention was first given to her. The result of now gas plates in the predominant majority are equipped with a gas leakage protection system. Such a mechanism of automatic shutdown of gas supply Manufacturers are often called easier: gas control. It is envisaged in case, for example, the flame will turn off the fled milk. So that the gas supply at this point stops, gas control turns off the gas tube. It works simply: when the flame goes out, the temperature sensor (each burner has its own) cools and sends a signal to the valve, which overlaps the gas supply channel. By the way, the modern control system can re-light the flame, "thinking" that it accidentally blew, say, draft. If the two-time attempt fails, the system throws it a useless thing.
Safety regulations
Do not leave the slate unattended.
Watch that children do not fit the work plate.
Watch the cooking process (especially on oil or fat), as ignition can happen.
Do not spray aerosols next to the burning burner.
Do not store flammable liquids or items near the plate.
Try not to include more than two burners at the same time and no more than 2h. Check the room more often.
But not everyone is such safety in the soul. After all, when the gas ignition is ignited, the sensor requires time for heating, and therefore it is necessary to hold the power switch for a few seconds, which is not very convenient. To light the burner, you blend the power switch (gas supply faucet), thereby opening the gas path to the nozzle. The gas jet is mixed with air, you make fire to the burner, and the mixture is flammable. But even then you should hold the switch, because if you release it ahead of time (while the sensor has not heated), gas control "will decide" that the flame went out, and block the supply of gas, respectively, the flame of the burner will disappear. Therefore, some prefer plates without gas control, confidently stating that before that, and without it. But those who are still worried about security, you should know that gas control can be incomplete: let's say, the burners on the cooking surface are controlled by them, but no oven. So when buying, specify that it is subject to gas-control.
Another achievement of modern technologies was the mechanism of electrical jagged, similar to a real magic wand: Gas lights up without matches and electricity. Elekdlyzhigi is two types: normal and automatic. For the first case - EKG 551102 W (Electrolux), ZCG566NW1 (Zanussi) - when turning the power switch, you must click on the ignition button to appear as a spark. APRRI Automatic Electric Higher - HGG 50521K (Kaiser, Germany), GI 477 E (Gorenje, Slovenia), K 246 GS (W) (Indesit, Italy) - Gas ignites automatically when turning the switch knobs. The automatic electrically rigging system works as follows. For the "inclusion" of the burner, you must drown the power switch and turn it. Simultaneously with the rotation of the handle closes the chain of the candle of the burner. Between the electrodes, located near the fire holes, slips the electrical spark, and the mixture lights up.
Of course, entrusting the connection should be a specialist, but you can control it. Is he doing right and keeps the security requirements? For you, it will be worthwhile to know several basic installation rules.
The slab is unpackled and inspected outside for the presence / lack of mechanical damage.
Next, it is connected to the gas pipeline by means of a bellows hose from stainless steel, the maximum length is 2m. Splicing hoses can not. There is a dielectric insert between the gas crane and the hose.
Then the slab is connected to the power grid (if necessary). If there is an electrofery and backlight, separate wiring is not needed (there is enough of the outlet of the lighting network). But if there is an electric arrow or an electric oven, it is necessary to carry out a separate wiring (cable 3g 1.5 or 32.5mm2, depending on the power of the device) with the installation of the EUROSTART outlet, and in the electrorecar, you should put the automatic protection for 16 or 25a.
The device grounds.
Install it in place.
Check the work of the slab in different modes.
When cooking always uses the timer. Simple Model - HGG 60501 (Kaiser), 3200 (GeFest, Belarus) - "Call" you, when the dish is ready, advanced - CE 62110 (BEKO), TRIO 501 (Candy, Italy) - will turn on itself, and when it takes, And turn off the slab (you need to set the time in advance). It is very convenient: breakfast will shoot your awakening. But there is a small catch. The fact is that the timers are calculated on the frequency of the current of 50 Hz, but in our networks the frequency is often slightly different, and therefore the timer either in a hurry or lags behind. Yves a plate with a plate turns on not at the time you have programmed. The error can be 3-5 minutes.
Spiritual work
Heating elements in the oven are electrical and gas. The latter - in such models like 1G20 (W) (Indesit), HSF 11K30N9 (Bosch, Germany), ZCG 55 GGW (Zanussi). Now advantageously produce models of plates, where the cooking surface is with gas, and the oven is electrical: EKK 601301 W (Electrolux), CE 61210 (BEKO), A 540 EB IX (Ardo). This is due to the fact that the temperature of the electrical heating elements is easier to adjust, and besides, they provide more uniform heating than gas. Indeed, at the top of the gas oven, poor conditions for the combustion of gas, and therefore food well spare only thanks to the gas burner located below.Depending on the model, the heating in the oven can only be on top, only below, and on top and bottom, and there are grilled, infrared heating, ventilation heating (convection) and different combinations of the listed. Let's say in the CX65SP4 (X) R / HA model (Hotpoint-Ariston, Italy) multifunctional oven (seven programs) with top heating and double grill. AV electric oven EKK513504W (Electrolux) There is a lower and upper heating, a fan, grill and their various combinations.
Choosing an oven, pay attention to the presence of so-called retractable rails for the opposites. Believe me, it will not only facilitate your home work, but will make it more secure - you will not negate. Well, when the oven door is heat insulated (in addition to the main glass, there may be 2-4 layers of optional). It will also help avoid burns.
Cleaning the oven - the lesson is not simple. But in low-cost plates, unfortunately, there is no self-cleaning. The height means that the oven is cleansed by the Dedovo way, that is, with the help of a napkin and a special means. It will simplify the process of catalytic cleaning - CE6VP4 (X) R / HA (HotPoint-Ariston), HSF 65K30N9 (Bosch): The inner surface is covered with a special enamel on which fats are decomposed.
Gas chamber
Of course, many problems arise with gas. The main thing is that his leakage can happen, the worst consequence of which is an explosion in the kitchen and destruction of the house. Leaks are for different reasons, but most often - due to improper gas treatment. With the appearance of gas controls, it is now difficult to leave the plate included without flame, but still troubles happen. In the early time, emergency services experts face that gas supply is violated due to illiterate reorganization of apartments. People interfere with the gas supply system, which cannot be categorically done. A situation is distributed when during repair the tenants themselves turn off the slab from the gas pipeline, to inability to violate safety equipment, and as a result - gas leakage. In this case, you must immediately call the emergency service.
In order for a person to immediately detect leakage, all combustible gases in gas pipelines subjected odorads, that is, they give them a sharp smell (by adding special odorant substances with a strong unpleasant smell (it is we take it over the smell of gas). You must feel it at the gas concentration in The air is not more than 1/5 of the lower limit of ignition. If such a trouble happened, it is necessary to close the overall gas supply valve, all the taps of the plate, open the windows and until the leakage does not include electrical appliances and light, and also forget about fire, that is, not smoking and not Loan matches.
But even if there is no leakage, the presence of a gas stove can create inconvenience. Gas spoils the kitchen climate. First, it requires about 1,5m3 air to form a mixture for the operation of four burners for 1. Secondly, the composition of air in the kitchen is very deteriorating when the burner is improved. So, if the gas-air mixture contains insufficient air, the gas is not completely incinerated, since part of its combustible components cannot enter into a chemical reaction, and this causes the formation of carbon-toxic and hazardous gas. The combustion products rise along the walls of the dishes and find themselves in the air of the room. That is why the correct burner work is very important, which should ensure complete combustion of gas, and therefore, it is necessary to regret it more often. Fullness of combustion can be determined by flame color. If everything is normal - a flame of blue. The air is larger than necessary - the flame is low, burns with hiss. The air is small - the flame rises high, with yellow tops and soak. Open models could be adjusted to the flame, changing the amount of incoming air, and when the modern instruments are released, the plant is already taken into the factory about the correct proportion of air mixing and gas, so the settings at home are not required.
Improper combustion of gas takes place and intensively using a stove. After all, when the four-door gas stove is working, the air exchange rate is 90m3 / h, which is not provided in every home. When the air is not enough, poor conditions for combustion of gas are created: the flame is high, with soak, it stands out more than harmful carbon monoxide gas. Therefore, the kitchen should have a good ventilation system.
Medicas are recommended to include at the same time no more than two burners and no more than 2h. If you can not follow these rules, more often ventilate the room. It is dangerous and by chance a wet burner. If the fluid hits the burner, the flame tongues over the wet fire channels are overtaken, and the gas continues to flow. The ion will not light up until the channels are dried. Fluid evaporation make it difficult to supply secondary air to the burner - there is no proportion of gas and air required for ignition.
Question price
Gas plates produce Ardo, Beko, Bosch, Electrolux, Gefest, Gorenje, Indesit, Zanussi Idr. The cost of plates begins approximately from 6 thousand rubles. - This is a simple option, as a rule, without electricity, but gas control is usually there (3100-08, GeFest; CG 41000, BEKO; K 1G20 (W), Indesit). For 9 thousand rubles. It is possible to purchase a stove with an electrofery (CG 51110 g, BEKO; ZCG 052 GW, ZANUSSI; G 470 W, Gorenje). More expensive 12 thousand rubles. There are models with self-cleaning oven coating and several types of heating oven (CG 61110 g, BEKO; A540 G6 W, Ardo; HSV 745050 E, Bosch).
