What is the stall for the boiler? Is it part of the interior of the combustion chamber? Is not it insecure like that, the indoor oxygen will enter the combustion chamber?
The grate of the boiler is a component that burns the mixed gas. Is part of the interior of the combustion chamber. Indoor oxygen will not enter the combustion chamber, because the boiler work in the micro-negative state, no indoor air, completely by the outdoor through the coaxial flue.
What you said is not a firing device. Burner: stove, grate to form a combustion chamber: burner, ignition electrode, air chamber frame in the grate there is a fire electrode, when the ignition electrode ignition, through the burner gas will instantly ignite, so It is not an ignition device. Indoor oxygen can enter the combustion chamber, because the boiler is used in a balanced flue, balanced flue is a double pipe chimney, the outer tube suction inner tube exhaust (the boiler of the fan has two major functions: Blower). In the combustion process, oxygen can enter the combustion chamber, in addition to the role of the fan there is another reason, that is, the density of oxygen than the discharge of the official satin pull and so on to advise the sea to the high density of air, so the oxygen will automatically down Go through the empty place below the burner into the burner.
The furnace is also called the burner, is the uniform output of the gas, so that the full combustion of gas components, is a combustion chamber components, the use of oxygen when the boiler is used, Sleeves are introduced from the outside, and when the boiler is burned, the indoor oxygen is not used.
