How to work with a gas burner

Functions and types of electric ignition

The schemes of modern ignition systems are different, but they have the same basis - the use of candles powered by a household electrical outlet of 220 V. When you turn the switch or press the button, the electrical circuit closes, the starting candle creates a spark on the burner with gas access. Electric ignition is divided into automatic and mechanical, which is also called semi-automatic.

The principle of operation of the fuse of gas stoves:

The pressed button creates a voltage applied to the capacitor area.
The capacitor is charged.
The voltage level on the thyristor rises.
The process of discharging the capacitor starts.
The spark gap is started with the release of a spark that ignites the blue fuel.

How to work with a gas burner What does the ignition block for a gas stove look like

In order for the process to be implemented, the stove must be connected to the mains, through a separate outlet from the line with a three-wire wire, with a cross section of at least 1.5 mm with grounding. In the electrical panel, a 16A circuit breaker is installed on this line.

Mechanical

For the operation of mechanical ignition, two types of transformers with 4 or 6 contacts are used. In the first case, a spark is struck only for the burners, in the second - additionally for the oven.

Scheme of operation of the mechanical gas ignition unit for the stove:

Turn on the button on the front panel, powered by electricity.
The process of charging the capacitor starts using the rectified voltage.
The accumulation of charges in farads begins, and the voltage of the main thyristor increases accordingly.
When the voltage peak is reached, the discharging of the capacitor begins with the heating of the primary transformer winding, which provokes the operation of the arrester with the release of a spark that ignites the gas in the open burner.

Mechanical ignition requires a piezoelectric element, so this type is often called piezo ignition. Today it is already difficult to find such a stove with mechanics in the distribution network among the novelties of gas equipment manufacturers. The principle of mechanical control is already becoming obsolete, since it is not entirely convenient due to the fact that in order to connect the unit, ignite the gas stove, in addition to turning the gas supply regulator, you also need to simultaneously press the spark starter on the panel.

Auto

Such ignition differs from mechanical ignition by the physical process of obtaining a spark, it does not require an ignition button, and the gas is ignited at the same time as the handle is turned. This system is more complex, since both the gas supply and the spark occur simultaneously. Moreover, the spark formation process is multiple and performs about 50 electrical impulses per minute, accompanied by clicks. This option is considered the most convenient, more often used in hobs and very rarely for ovens. The control mechanism can be seen if you remove the flame diffuser from the burner, it is located approximately on the side in a small niche.

The scheme of its operation of automatic ignition:

To create a spark, the user slightly lowers the knob for turning the desired burner and scrolls it to supply gas;
at this moment, the spark plug located in the burner niche closes and ignites the gas exiting the nozzle holes.

Electric ignition schemes

Depending on the type of electric ignition, there are two options for the schemes of gas stove ignition blocks:

Single spark ignition - when the ignition button is released, a single spark occurs.
Multi-spark - by turning the burner knob, a continuous spark is generated.

The first scheme works like this:

when the ignition button is pressed, the mains voltage is applied to the capacitor, it is charged;
when the button is released, the capacitor contact is connected to the transformer;
the reverse process is performed - the capacitor is discharged through the primary winding of the transformer;
a voltage of about 10 kV is formed on the secondary transformer winding;
a spark is formed;
pressing and releasing the button will repeat the process.

How to work with a gas burner

The second circuit works like this:

with a positive half-wave of the mains voltage, a capacitor is charged through the diodes;
with a negative half-wave, the cathode is connected to the “negative” half-wave, and a control current is supplied through the resistor to the control electrode of the thyristor;
the thyristor opens and the capacitor is discharged to a high-voltage transformer, which produces a spark;
a voltage of about 10 kV appears on the secondary transformer winding;
while holding the gas supply knob, the process is performed at a frequency of 50 Hz (1 spark per second).

Note! There is a 4-ex or 6-electrode ignition. The number of electrodes depends on the number of secondary windings of the step-up transformer

Six-electrode ignition blocks are usually used in combined types of stoves in conjunction with an oven. Two of the six electrodes are located in the oven and work specifically for its ignition.

Advantages of a gas burner on a can

Compared to liquid fuel, gas burners have many advantages. They run on environmentally friendly fuel, ignite instantly and do not leave any residual combustion products after their use.

Thanks to the use of gas, it is possible to pay minimal attention to cleaning the internal parts of this device.

The portability and compactness of the gas burner on a small-capacity cartridge allows you to direct the flame jet at any angle that is necessary for the owner to work comfortably. This device can be used in various situations - when lighting raw firewood and charcoal, when soldering parts with tin-copper solders, when creating decorative patterns on wood, and also in cooking - in order to caramelize sugar. And this is only a small part of the possibilities for using this product.

After purchasing this device, you must carefully study the operation and safety instructions. You can use the burner only strictly following all the rules for its use. Overheating of the gas cylinder is unacceptable - it must not be left in the hot sun or near heating devices. After prolonged operation, a strong cooling of the tank occurs, due to which the power of the torch decreases. To avoid this, a special catalytic heating pad is put on the cylinder.

A gas burner will be a reliable and efficient assistant for its owner. The presence of this device on the farm will be able to solve a lot of problems that may arise at any time. Its correct use will bring a lot of positive emotions, and will help to realize any ideas, no matter how difficult they may seem at first.

Safety requirements when working with gas burners when installing a new soft roof or repairing an old rolled waterproofing material

2.1. When working with flame equipment, it is recommended to use protective goggles.

2.2. When igniting a manual gas-flame burner (working gas is propane), the valve should be slightly opened by 1/4 - 1/2 turn and after a short purge of the sleeve, the combustible mixture should be ignited, after which the flame can be adjusted.

2.3. Ignite the burner with a match or a special lighter; it is forbidden to light the burner from random burning objects. With a lit burner, do not move outside the workplace, do not climb ladders and scaffolding, do not make sudden movements. The burner is extinguished by closing the gas supply valve, and then lowering the locking lever. During breaks in work, the burner flame must be extinguished, and the valves on it must be tightly closed. During breaks in work (lunch, etc.), the valves on gas cylinders, reducers must be closed.

2.4. If the burner overheats, the operation must be stopped, and the burner extinguished, and cooled to ambient temperature in a container with clean water.

2.5. Gas-flame work must be carried out at a distance of at least 10 m from groups of cylinders (more than 2) intended for gas-flame work; 5 m from individual flammable gas cylinders; 3 m from gas pipelines of combustible gases.

2.6.When igniting a manual liquid burner (working fuel is diesel fuel), the compressor is first turned on, supplying a small amount of air to the burner head (valve adjustment), then the fuel supply valve is slightly opened and the resulting fuel mixture is ignited at the head cut. A steady flame is established by successively increasing the flow of fuel and air. The compressor can only be moved when it is switched off.

2.7. If a gas leak is detected from the cylinders, work should be stopped immediately. Repair of cylinders or other equipment at the workplace of flame works is not allowed.

2.8. If the reducer or shut-off valve freezes, heat them only with clean hot water.

2.26. Gas cylinders must be at least 1 m away from heaters and 5 m away from heating stoves and other strong heat sources. Do not remove the cap from the cylinder with blows from a hammer, chisel or other tool that can cause a spark. The cap from the cylinder should be removed with a special key.

2.9. Protect sleeves from various damages; when laying, avoid flattening, twisting, bending; do not use oil hoses, do not allow sparks, heavy objects to get on the hoses, and also avoid exposure to high temperatures; do not allow the use of gas hoses for supplying liquid fuel.

2.10. Pneumatic hoses are used to supply compressed air.

2.11. When working in non-permanent places, cylinders must be fixed in a special rack or trolley and protected from heating by sunlight in the summer.

2.12. Gas cylinders should only be moved on specially equipped carts.

Upon completion of roofing work using a gas-flame burner, the roofer must: — close the fuel supply valve to the burners, close the valve on the cylinder, turn off the compressor; - remove the sleeves with reducers from the cylinders, wind them up and put them in the designated storage area. - close the valves of the cylinders with protective caps and put the cylinders in the room for their storage; - clean the workplace, remove tools and fixtures, materials, glasses, burners, cylinders; - inform the master (foreman) about all the problems noticed during work.

The main characteristics of gas burners on a can

Gas burners on a cartridge have different power - it depends on the composition of the gas mixture and, accordingly, on the flame temperature, which can range from 1000 ° C to 2500 ° C. The pressure of the gas in the cylinder also plays a significant role in the efficiency.

Some models have a built-in nozzle regulator, which allows you to change the diameter of the flame jet to obtain a torch of the desired size. It is also possible to change the supply of the gas mixture from the cylinder. Thanks to this, you can increase the power of the device used.

Compact liquefied gas cylinders have various types of connection to the burner - threaded or collet. The conventional gas mixture filled into the tanks allows the burners to be used at ambient temperatures between 5°C and 45°C. Special gas mixtures, which include isobutane/butane/propane (the so-called "winter mixtures"), allow you to work at low temperatures. They make it possible to create a torch with a temperature of more than 2000 °C.

On sale there are models weighing from 70 grams - excluding the cylinder. This greatly facilitates the use of this device by the owner.

SAFETY REQUIREMENTS DURING WORK

3.1. The gas cylinder must be firmly installed on a level, well-ventilated (ventilated) area and secured. 3.2. The use of gas cylinders for work in confined spaces is allowed provided that effective ventilation is ensured. 3.3.When working with a gas cylinder, it is necessary to take measures to prevent shocks, shocks, falls, and when working at an outside air temperature below 00 C - from freezing. 3.4. All devices connected to the gas cylinder (reducer, hoses, burner) must be in good condition and periodically checked: - burner - at least once a month for gas tightness; - gearbox - at least once a quarter technical inspection and testing; - hoses - daily - for cracks, screeds, etc. 3.5. There must be no cracks, ties, etc. on the gas hoses. 3.6. Before connecting the reducer to the cylinder, it is necessary to blow out the reducer fitting to remove foreign particles from it. 3.7. The reducer must be attached to the gas cylinder only when the cylinder valve is closed. 3.8. After connecting the reducer, slowly open the cylinder valve and set the working gas pressure. 3.9. The length of the hose, depending on the working conditions, must be in the range from 8 to 20 m. 3.10. Regardless of the place of work, the following distances from the gas cylinder to: - heat sources (for example, heating radiators) - at least 1 m; - open fire - not less than 10 m. 3.11. When working with gas cylinders, it is prohibited: - to install cylinders in an inclined position; - install cylinders in the aisles, driveways, in the place of accumulation of workers, in poorly lit places; — expose the cylinders to sunlight; - perform work without a gearbox; - use hoses made from separate scraps or interconnected with wire, clamps; - leave unattended cylinders in operation with open valves; - disassemble and repair the burner connected to the gas cylinder; - warm the frozen gearbox with an open fire; - smoking and eating at the workplace; the presence of strangers. 3.12.
