The burning equipment is coal feeder and squama chain-grate. This boiler can be used as large centralized steam boiler of heat supplying station and heat-load peak adjusting set of heat and power station. Features:1) This model is with double-drum horizontal laid structure. When the feeding water enters the coal economizer, it enters in the steam drum. The layout of the heating area is of enough margins. The front, back, and side walls form enough circulation height, thus the water circulation is safe and reliable2) The boiler drum with large steam space consists of underwater orifice plate, even gas orifice plate and corrugated plate separator in addition to water feeding and cleaning devices. Then the salt melted in the steam can be transferred to the fed water through quality exchange, thus the steam quality can be greatly enhanced 3) The front water-cooling wall and the back water-cooling wall form the front and back arch respectively. The front and back arch is made of fire-proof materials to reduce the surface heat absorption capacity to form high temperature area for strong radiation. With ignition, there are strong high-temperature vortex cavities under the front arch. The burning is strong under the back arch, so that the coal adaptability can be greatly enhanced 4) Non-coal-leakage squama chain grate is adopted. The main advantages include little coal leakage and even draught, easy to clear up the coal ash. The chain withstanding the pull of the grate is under the chain-grate late and does not touch the fire bed directly, thus, the operation becomes even more reliable. As the boiler chain and the chain grate are in soft structure, making the manufacturing precision and the installation requirements of the axle shaft chain wheel relatively low. The boiler chain can be adjusted automatically to reduce Paya accidents. The chain grate can be installed and unloaded conveniently, making the examination and reparation easier. The chain grate can be replaced on the condition of non-stop boiler. It is with good dust cleaning performance. The container installed on two sides of the chain-grate is playing the role of water-cooling iron with very reliable anti-retarding function for the hearth
