机械炉排锅炉炉渣含碳量高,超出国家规定的要求。我们在对辽宁省五金公司仓库、沈阳市邮政局大修厂等单位六台燃煤锅炉的改造中,改装水平逆推往复炉排,将原炉排末端一排固定炉排,增为两排或三排。即将末端固定炉排长度加长一倍或两倍,在运行中,对降低炉渣含碳量产生明显效果。经过改造后热工测试及化验分析,省五金公司仓库锅炉炉渣含碳量为4.16％,市邮政局大修厂为8.25％,市汽车三公司一队为4.91％,其他也都在10％以下。过去这些锅炉都因种种原因不好烧而停止运行。在改造中,除因有其它原因使炉渣含碳量降低外,有一处过去有明显区别的是加长了炉排末端固定炉排长度。改造前末端只有一排固
Mechanical grate boiler slag carbon content is higher than the national requirements. In the transformation of the coal-fired boilers of Liaoning Province Hardware Company warehouse and Shenyang City Post Bureau overhaul factory and other units, we retrofitted the level reciprocating reciprocating grate to add a row of fixed grate at the end of the original grate to two rows or three row. About the end of the fixed grate length lengthened double or double, in operation, to reduce the carbon content of the slag have a significant effect. After the transformation of the thermal test and laboratory analysis, the province’s hardware company warehouse boiler slag carbon content of 4.16%, City Post Office overhaul plant was 8.25%, the city of the three companies a team of 4.91%, others are also below 10%. In the past these boilers all stopped working due to various reasons. In retrofitting, in addition to reducing the carbon content of the slag due to other reasons, one obvious difference in the past is that the grate length at the end of the grate is lengthened. Before the transformation only a row of solid end
