WNL4-13-A_3型工业锅炉改烧次煤时燃烧操作技术及设备改进

THE COMBUSTION OPERATING TECHNOLOGY AND IMPROVEMENT ON THE EQUIPMENTS IN THE IND- USTRIAL BOILER WNL4-13-A _3 WHEN THE POOR QUALITY COAL IS USED AS FUEL IN THE BOILER

对 WNL 4-1 3 -A3型锅炉原设计的三类烟煤改烧次煤进行了设计计算 ,采取了调整煤层厚度、降低引风机风量、增设炉拱、减少炉体漏风等措施 ,使锅炉运行良好 。

Accoding to the original design the third class of coal is used as fuel in the boiler WNL4-13-A 3. When the poor quality coal is used as fuel in the boiler, the boiler is in a good state and the heat efficiency is raised by means of changing the thickness of coal layer and reducing air flow of the wind machine and increasing the quantity of furnace arches and decreasing the air leak of the boiler body and so on on the basis of the design calculation.
