YLW series boiler is a square coil horizontal chain grate assembly boiler, chain grate and boiler body is delivered separately, after the site is in place, only need to turn on the oil, electricity can be put into operation, the furnace is realized by chain grate Mechanical coal, equipped with drums, induced draft fan for mechanical ventilation, and equipped with slag machine to achieve mechanical slag.
During operation, the fuel falls from the coal hopper to the grate for combustion. The high-temperature flue gas passes through the rear arch and enters the furnace in front of the furnace. After radiative heat exchange on the radiant heat surface, it enters the convection heating surface for convection heat transfer, and then leads to waste heat. The boiler enters the air preheater and enters the precipitator. After the dust is removed, the exhaust gas is drawn by the induced draft fan through the chimney to the atmosphere.
The boiler heating surface consists of four parts: the radiant heating surface of the furnace, the convection tube bundle heating surface, the waste heat boiler, and the air preheater (economizer).
