DHL series of corners of the chain furnace grate boiler with "high temperature separation of fly ash within the circulating fluidized refueling device" and other two utility model patented technology, with high thermal efficiency, low operating costs, long-term trouble-free operation, Low concentration of emissions, light weight, less investment in infrastructure, chip factory, on-site installation of small workload, the installation cycle is short and so on, is China's large-capacity hot water boiler the latest alternative products. DHL series of corners of the chain furnace grate coal-fired boiler products can be used as urban and industrial and mining enterprises and other central heating heat source host, stand alone for 300000-400000m² building area heating, but also as a thermal power plant peak boilers, adjust the city heating network operation. For those who need a lot of hot water of industrial and mining enterprises the boiler can meet their needs. The boiler is arranged in the form of "n" type, which consists of Φ1600mm drum, furnace water wall, external descending tube, large scale chain grate, two group economizer and tube type air preheater, which is arranged in boiler Four corners, not only as a water circulation channel, but also as a support frame for the boiler, the angle is arranged on the tube without heat and self-supporting boiler called the corner tube boiler. Drum for the external, the furnace is fully enclosed membrane wall structure, convection heating surface with gas pipe structure, no steel frame, water cycle unique and safe, start quickly. Boiler design for the double-layer layout, but also a layer of layout, can be used two vertical coal on a separate coal, but also for coal transportation. The boiler body is made of lower support, ceiling, heat-resistant concrete light furnace wall, the top of the furnace, the load of the eight columns, the boiler working fluid is treated soft water, the design return water temperature is 70 ℃, the water temperature is 130 ℃, Temperature 90 ℃, the water temperature of 150 ℃ operation.
