The cause of the coking chamber of a stove or furnace

                             The cause of the coking chamber of a stove or furnace

Some of the reasons for coking in the hearth, roughly as follows:
(1) the nature of the ash. The higher the ash melting point, the less easy to coking. Conversely, the lower melting point, the easier it is to coking.
(2) the surrounding medium has a very big impact on the coking. Combustion process, caused by a lack of air supply or fuel and air mixture, and makes the fuel not achieve complete combustion, incomplete combustion will produce a reducing gas, ash melting point will be greatly reduced.
(3) run the improper operation, the flames of deflection or the primary and secondary wind cooperate is unreasonable, a wind speed is too high, particles without complete combustion, and in the condition of high temperature to soften, continue to burn adhesion to the surface and form coking.
(4) furnace volume heat load is too large. The boiler furnace temperature is exorbitant, run outside force ashes arrived in water-cooled wall and furnace exit, also can't get enough cooling, resulting in the coking system.
(5) blowing, decoking not timely, caused heated side wall temperature is high, so that the heating surface have serious coking.
