The boiler shall adopt double drum, monolayer arrangement, compact structure, as well as large heating surfaces which are more 10 per cent than those of same kinds of products, featuring the following advantages such as sufficient output, safe and reliableoperation, short construction period, and low installation cost ect.2. The design of cyclone reburning chamber in furnace resulted in the decrease of dust contained in the flue gas.At the same time, incandescent carbon black particles 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.3. The grate shall employ the technology patent of small roller structure, boundary grate and so on, improving the operation reliability of the boiler4. Since the adoption of technology patent for the sealed wind chamber and bilateral grate air ,and the application ofmachining cone seal structure to grate adjusting air equipment, the sensitivity of the grate shall be improved,5. The boiler was awarded the following titles: first class products of mechanical and electrical department, excellent energy-saving products promoted by state, excellent energy-saving products of Shandong province.6. According to the customers' requirements, the layering burn device and other energy saving equipments, implemented in state,shall be matched.
