Coal Fired Steam Boiler, also called coal fired hot water which can also used to generate hot water, is widely used to generate steam for industrial usage by burning pulverized coal that is blown into the firebox. TANSHAN Brand SZL coal fired steam boiler has the characteristics of big heat surface, high heat efficiency and the flake type chain grate, less coal leakage, respective air chamber and separated adjustment, sufficient and steady burning. Its outlet dust separator device reduces flue gas drain, frequency control, PLC & DCS auto-control. SZL coal fired steam boiler is specially designed and optimized for applications to produce low and medium pressure steam or hot water with rated evaporation capacity from 2 to 35 ton/hr and rated pressure from 0.7 to 2.5 MPa. The design heat efficiency of SZL coal boiler is up to 81~82%. Features of SZL Coal Fired Steam Boiler 1. Ex-work by up and down separate parts, lay out by single floor. 2. Compact structure, easy installation and less civil investment . 3. Automatic control at water feeding, coal feeding chain grate running, dust removing, ID air control, FD air control. Interlock protection of over pressure (for steam boiler), over temperature (for hot water boiler), high and low water level (for steam boiler), guarantee its safely running. 3. Two sides feeding air, single air chamber, separate adjustment. To avoid wrong pass air and partial burning, due to air distribution unevenly under chain grate. 4. Use high strength big size chain plate, avoid the breakage of the plate, reduce coal leakage·
