【摘要】 针对石家庄和保定热电厂的老厂状况,为减少污染物排放,扩大供热量,进行了“以大代小”技改方案的论证。通过分析,提出分别建设200MW和125MW等级的双抽汽式供热机组,锅炉采用410t/h和450t/h等级的循环流化床锅炉,2厂锅炉总蒸发量达到2540t/h。更多还原

【Abstract】 In right of the conditions Shijiazhuang and Baoding two old co generation power plants,in order to reduce the discharge of pollutants and incr ease the heat supply,the retrofitting scheme "with large size unit to replace small one"has been expounded and verified.Through analysis,the following sugg estions is put forward:to build200MW and125MW class double-extraction s team tur-bines separately in the two power plants,completed with410t/h an d450t/h class circulating fluidized bed combustion(CFBC)boilers,the total evaporation capacity of boilers in two power plants will reach2540t/h.更多还原
