河南省唐河县化肥厂1980年购进一台SZL10—25/400型链条锅炉(简称十吨炉),安装投产后,蒸发量始终达不到设计能力,而且煤电消耗也高。针对这一问题,该厂工程技术人员进行了认真地分析研究,设计了一个“煤层疏松器”(简称“松煤器”)装在锅炉燃烧室前,用来调节进入炉膛的煤层密度。安装后,经过八个月的运行实践,证明效果良好。该锅炉蒸发量由原来的8.5吨/小时;上升到11.6吨/小时;炉渣残碳量由原来的15％下降到5.5％;送风机电流由原来的59安培下降到43安培;吨氨耗烟煤也由原来的768公斤下降到422公斤。
Tanghe County, Henan Province, fertilizer plant in 1980 purchased a SZL10-25 / 400-type chain boilers (referred to as ten tons of furnaces), after installation and commissioning, the evaporation capacity has not reached the design capacity, and coal consumption is also high. In response to this problem, the plant engineering and technical personnel conducted a careful analysis and design, designed a “coal loose” (“loose coal”) installed in front of the boiler combustion chamber, used to adjust the density of coal into the furnace. After installation, after eight months of operational practice, proved effective. The boiler evaporation from the original 8.5 tons / hour; rose to 11.6 tons / hour; residual carbon from the original 15% to 5.5%; blower current from the original 59 ampere down to 43 amps; tons of ammonia-bituminous coal also From the original 768 kg down to 422 kg.
