Gas stove for a reason. According to standards, when installing an electric cooktop, the tariff is halved, in practice it is impossible to get the required discounts. They didn’t go into the specifics of the legislation, even if you put the counter two-tariff, having equipped the apartment distribution panel, you won’t get into trouble. They write, utilities concluding contracts, do not leave room for discounts. The situation, as some wise men put it, is funny. It seems there is a law, it is impossible to implement on the ground. Gas is inexpensive, although the efficiency of the devices leaves much to be desired, the general gasification, which the USSR was fond of, lets know: we are wary of induction hobs. Buyers interested in the device gas stove.
Burner gas stove
Let's start the burner, gentle housewives are afraid to remove the cover, the divider, considering it dangerous. There is nothing reprehensible( avoid throwing foreign objects inside), make sure that the injector is not blocked( a small nozzle, through which gas comes from the internal collector through the pipes).When washing the table of a gas stove burner must be partially disassembled, otherwise the high-quality operation is simply impossible. Wait until the hotplate cools down. The cover is removed, the divider is pulled out( a detail with teeth on top, like a medieval tower).Do not wash the stove with abrasive objects( dish net), use chemicals. Water does not cope with pollution.
Under the divider a small nozzle that regulates the amount of gas supplied. Inside the gas stove, pressure adjustment mechanisms help to achieve steady burning. The burner is characterized by power, distinguish:
- The minimum power of the existence of a stable flame. The regulator is in extreme position.
- Maximum power - energy delivered per unit of time under conditions of full gas supply: the burner is heated, there is no flame separation.
- Rated power is determined by the maximum complete combustion of the gas. Homegrown masters to find the point will be difficult, the technical characteristics of the gas stove include a number.
Replacing the old type of fuel with new ones, we rearrange the injectors( nozzle).Power remained the same, the gas stove is working properly. It is important. If the gas flow is too strong - the burner will smoke, the gas burns partially, the flame is unstable. An experienced master adjusts the stove, guided by the parameters( like a gas boiler): pressure, calorific value.
Burner power is calculated by the formula: N = Q x V;Q is the minimum specific heat of combustion of a cubic meter of gas;V is the average consumption of blue fuel every hour.
We add one characteristic - the limit of thermal power regulation: n = Nmin / Nmax. We suppose the formula explains the physical meaning of the parameter. Burner three types:
- diffusion;
- kinetic;
- diffusion kinetic.
The meaning of the names generated by the characteristics of burning. Diffusion pre-mix gas, air avoided. A trickle of blue fuel is thrown into the burner, a mixture is formed. An example of the second case is the injector, the air is sucked in by the energy of gas movement( Bernoulli effect), and a ready combustible mixture is formed. Most kitchens will demonstrate the third type. Half of the air is taken from under the table, the other - from the kitchen. The result is a combustible mixture.
The received information is full of values. Gas oven corresponds to the first, diffusion, type of burners. Air supplies the surrounding space. The task of the wizard is to set the burner correctly. General requirements:
- The most complete combustion gas.
- Stable operation in all modes.
- Reliability and ease of maintenance.
It is clear that the parameters of gas stoves are determined by the burners. The formation of a mixture, ignition. Electric ignition models have spark plugs. I chose the periphery of the divider, it works once - when opening the gas supply regulator. Often there is a thermocouple that controls burning. The fire goes out, the fuel supply valve is closed. Looking ahead, let's say: the burner is powered by an individual path blocked by a solenoid valve. It is necessary to press the handle plate( opening the valve manually), turn until the mixture ignites, hold while waiting for the thermocouple to heat. The open state of the system will provide the EMF of the thermocouple.
The fire is extinguished, the force that keeps the coil core open is lost, the supply of blue fuel is stopped. Please note that gas stoves, started cooking, equipped with electrical ignition, plugged into an outlet, the presence of food does not matter. There is no light, set fire to the gas with a match, hold the handle while the mechanism is engaged, calmly go about your business. Before doing this, carefully read the hardware manual. If the technical characteristics of gas stoves are determined by the burners, the operation depends on other units. In conclusion, let's say: the burners increase the power very simply by increasing the diameter of the nozzle opening. As a result, the volume of the combustible mixture increases, the injector provides a faster fuel supply.
In other words, it is impossible to take injectors from one plate, to rearrange to another. We take into account the burner power, gas pressure, specific heat of combustion. Pisaki in the know: the knowledgeable masters bore injectors under the necessary parameters, indicated how dangerous it is to do an inexperienced person. Hole can be enlarged or narrowed. However, in practice, operations are not recommended. Refinement with gas stoves produces a professional( forget the gas service).
Gas stove ignition device
It is clear that the principle of operation of a gas stove is not difficult. Blue fuel burns, pans are heated. Difficulties hidden device monitoring and protection. How does the gas stove.
For the ignition of the plate used electrical circuit on the power components. First, how to find a candle on the stove? Key feature in good electrical insulation. White ceramics do not allow the rod to break through anywhere, bypassing the body of the divider. It is appropriate to remind: the electrical plate is grounded for proper operation, safety of people. The current pierces the instrument housing to produce a spark. The second sign is decisive: if you remove the table, you can see: the wires come from the electronic ignition board. Thick, powerful. From the thermocouple is twisted pair to the valves, most often located in the area of power regulators.
The rest of the candles are similar to each other. As for the operation, you can press the ignition button, visually see on which the spark will slip a spark. The gas should be closed, the cover of the divider is better to remove. There is no control over the supply of blue fuel, therefore, the ignition should work. The control of burning is important. ..
Gas enters the stove through a pipe, goes to the collector. A branch pipe fitted with branches, each has a valve. The device of the gas stove does not do without protection. From the thermocouple is twisted pair to the valve.
If you mix them up during assembly, the gas stove will no longer support combustion, the flame will go out. Even if it is possible to light two burners, which are reversed, no protection against the extinction of the fire. The situation happens - get a guaranteed explosion. Be careful when connecting thermocouples, solenoid valves.
Electronic ignition board can be easily detected. There is a capacitor, the charge of which passes through the primary coil, causing a potential of a few kilovolts to appear on the secondary. Candles are connected in pairs, stand one at the end of the winding. For example, for four rings are arranged in pairs. A spark hits in pairs through the candles, the current flows through the body to the ground. It is clear that it is difficult to get an electric shock due to the presence of powder paint on the desktop, security measures must be taken. In terms of ignition, the principle of the gas stove is as follows:
- On a positive half-wave, the capacitor is charging. It accumulates energy.
- On the negative is locked, discharged by the triac on the primary winding.
The rest of the process is described. The throttle is able to form a spark, it happens in the starting devices of discharge lamps. The technology of storage of energy of a magnetic field( not electric) works. Now readers know how the gas stove works. Connection must only be made to a certified hose. Otherwise, the spark pierces the pipe, the material burns, an explosion is possible. Discussed on the portal VashTehnik.
