Oil Burners - Types of Monitoring -
Fire! Fire! .. The machines we use every day and how they work

Oil Burners:

The thermostat is also used in furnaces that use oil as fuel. It is the one that starts the electric motor, and it is the one that stops it from working. This motor performs two functions. It operates a small pump whose job is to draw oil from the tank to the furnace, and it also operates a fan that pushes air into the furnace to mix with the oil and help it burn. But the oil does not ignite unless it is heated first. This process is carried out by a small device called a spark generator, whose function is to generate electric sparks. Such sparks contain an amount of heat sufficient to ignite the oil. In some stoves, the oil ignites under the influence of a gas flame.

Types of monitoring:

The design of oil stoves and automatic igniters includes many monitoring devices, the task of which is to facilitate their operation. One of these devices is called the low water level valve. This device does not allow the fire to ignite unless there is a sufficient amount of water in the boiler, because if it ignites, the metal walls will heat up to an unbearable degree, and they will shatter. This device prevents this. It is an electric switch, which turns the weight of the water in the boiler and this switch closes the electric current to the motor if there is not a sufficient amount of water. If the motor stops, the supply of coal or oil to the furnace stops, and then the fire goes out without any loss.

There is another monitoring device called the high pressure valve. This device has a double thermostat control. The thermostat stops the fire when the house is heated to a suitable temperature, but what happens if the thermostat fails to do its job? The fire continues to burn, emitting an amount of steam that gradually increases until it fills the pipes and then explodes. The high pressure valve prevents this. This device is an electric switch that operates on steam pressure. When the pressure rises, the switch (switch) stops the electricity flow, so the motor stops supplying the tank with coal or oil, and then the fire goes out.

What happens then if the high-pressure device stops working? There is another monitoring device ready to work. This device is the safety valve. This safety valve is a cover for the hole in the boiler. It is fixed in it by a compression spring that pushes it until it stabilizes in its position. If the steam pressure increases greatly and the high-pressure device stops working, the steam becomes so strong that it can push the cover from its hole in the boiler. This last process allows the steam to leak into the basement, without causing damage. This basement will undoubtedly become damp. But the problem of this dampness is much easier than the problem of a burst steam pipe or the explosion of the heater itself.

It is very rare - almost non-existent - for the high-pressure device to stop working, or for the thermostat to fail. If one or both of them fail, there is a valve Security, which instills confidence and reassurance in our souls.
