YLW series coal and biomass fired thermal oil boiler is horizontal type square coil chain grate boiler , equipped with forced fan and induced fan for mechanical ventilation, and slag remover for mechanical slagging.
During operation, the fuel falls from the upper hopper to the grate for combustion. The high-temperature flue gas is reflected by the rear arch to the furnace and enters the furnace. After the radiation is heated by the radiation heating surface, it enters the convective heating surface for convective heat transfer, and then leads to the waste heat boiler or Air preheater, and finally enter the dust collector. After dust removal, the flue gas is drawn by the induced fan and discharged to the atmosphere through the chimney.
