我国小型锅炉在工业生产和生活中应用广范、数量大、种类多。如 KZL 型快装纵置式链条炉、KZW 型快装纵置式往复炉排、SZS 型双锅筒纵置式往复炉排、SHS 型双锅筒横置式链条炉、WNL 型卧式内燃链条炉以及各种立式水管、火管或水火管混用锅炉等,约有30万台,年耗煤量达2亿吨,占我国原煤产量的三分之一。小型锅炉是重点耗能设备,其燃煤量大,燃煤后的产物——烟气量也大。若30万台小型锅炉,每台锅炉单位时间烟气量按10000米~3/时考虑,烟尘排放测试按平均数值(按最少值算)为300毫克/标米~3计算,则每小时将有900吨烟尘排放到大气中。劳动局和环保局要求锅炉烟气排放标准为
China’s small boilers in the industrial production and life of a wide range of applications, the number of large, many kinds. Such as KZL-type vertical mounted vertical chain furnace, KZW-type vertical longitudinal reciprocating grate, SZS double-drum vertical reciprocating grate, SHS-type double drum horizontal chain furnace, WNL-type horizontal internal combustion chain furnace and the There are about 300,000 sets of vertical water pipes, fire tubes or water-fire tube boilers. The annual coal consumption amounts to 200 million tons, accounting for one-third of China’s coal output. Small boilers are the key energy-consuming equipment, the large amount of coal, coal-fired products - the amount of flue gas is also large. If the 300,000 small boilers, flue gas per unit of time per unit of time by 10,000 m ~ 3 / time to consider, the soot emissions test by the average value (calculated as the minimum) of 300 mg / m ~ 3 calculation, the hourly 900 tons of soot discharged to the atmosphere. Labor and Environmental Protection Bureau requirements for boiler flue gas emissions standards
