    sign ones. Compared with boilers burning bituminous coal, boilers burning anthracite and lean coals have higher NOx emission and lower boiler efficiency. This indicates that boiler mode and coal type have big impacts on boiler performance and NOx emission. Normally, boilers burning higher volatile coal pro-duce less NOx[7,8]. The reasons are: (1) coal combustionLearn More
