一、公司规模简介宁波长丰热电公司一期原来安装有3台75吨循环硫化床锅炉,配备2台C15-35/10抽凝机组, 选用4台85m3/h电动定速给水泵。随着发电量和对外供热量日益增加,原有的设备已经不能满足要求。从2003年4月份起,二期扩建工程正式开工,扩建规模为1台150吨循环硫化床锅炉和1台7.5MW背压式供热机组,扩建以后锅炉额定产汽量达到150t+3×75t=375t,而3台机组发电负荷达到2×15+7.
First, the size of the company Ningbo Changfeng Thermoelectric Company originally installed three 75 tons of circulating fluidized bed boiler, equipped with two C15-35 / 10 pumping condensate units, the selection of four 85m3 / h electric constant speed feed pump. With the increasing power generation and external heat supply, the original equipment can no longer meet the requirements. From April 2003 onwards, the second expansion project was officially started to expand the scale of a 150 ton circulating fluidized bed boiler and a 7.5MW back-pressure heating unit, the expansion of the boiler rated steam output reached 150t +3 × 75t = 375t, while the power generation load of 3 units reaches 2 × 15 + 7.
