目前,北京市有近四千台快装链条锅炉,其中KZL4-13型锅炉约占2/3,从46台锅炉的热工测试报告统计得知:平均热效率59.6％、出力2.39t/h(最高的也不过3.2t/h)、煤耗153kg标煤/t蒸汽,排烟温度和炉渣含碳量比较高,还有炉墙散热、漏风等问题都造成热损失偏高。针对此情况,我们根据上海改造KZL4-13型锅炉的经验,先后在北京市沥青混凝土厂等单位进行了试点,结果表明:出力可达
At present, there are nearly 4,000 quick-loading chain boilers in Beijing, of which KZL4-13 boilers account for about 2/3. According to the thermal test report of 46 boilers, the average thermal efficiency is 59.6% and the output is 2.39t / h The highest but also 3.2t / h), coal consumption of 153kg standard coal / t steam, exhaust gas temperature and slag carbon content is relatively high, there are furnace wall heat, air leakage and other issues have caused high heat loss. In response to this situation, we based on the experience of Shanghai to transform KZL4-13 boiler, successively in Beijing asphalt concrete plant and other units conducted a pilot, the results show that: output is reachable
