Chain Grate Boiler ZG proposes a highly efficient and completely automatic coal fired steam boiler using combination of water tube and fire tube boiler design and well known chain-grate burner. The boiler is a combined fire tube and water tube designed to burn bituminous coal. The boiler system is complete with coal feed hopper, chain-grate for burning the coal, dust collector system, combustion air fan, induced draught fan, ash conveyor and the control panel. BASUKI can supply, erect, and commissioning complete boiler plant for any application. The capacity of boiler vary from 6 ton/hour up to 30 ton/hour with saturated steam delivered at pressure from 10 up to 22 barg. 1.The boiler shall be employed monolayer arrangement,featuring the following advantages:compact structure,easy installation and operation, and low cost of boiler house,which shall economize more than 40 percent on investment of boiler house. 2.The design of natural circulation convective heating surface for the boiler resulted in sufficient outgas, low accident rate, and safe and reliable operation. 3.The grate shall use the technology patent of scale-type fire bars, boundary grate and so on, improving the operation reliability of the boiler. 4.The design of chamber in furnace resulted in the decrease of dust contained in flue gas. At the same time, incandescent carbon black shall burn further, enhancing the boiler thermal efficiency, and decreasing gas blackness, as a result, the gas emission concentration shall meet the requirements of grade A environmental protection area. The bigger diameter ash particle of the flue gas shall be separated form cyclone reburning chamber simultaneously decreasing the dust concentration contained in the flue gas from convection bank, reducing the erosion of convection heating surface, and improving the boiler life. 5.Beside of the sealed wind chamber, entering wind by both sides, and the application of machining cone seal structure to grate air register, the sensitivity of the grate shall be improved, which is national protected technology patent. 6.PLC Based system controller 7.According to the customers’ requirements, the layering burn device and other energy saving equipments, implemented in state,shall be matched. In conclusion, ZG chain grate boiler is not only fully automatic, high efficiency, high turndown ratio,but also water tube and fire tube combination offering capacity flexibility, but also with low emission ,advanced control system technology, low electrical power consumption.
