冬季采暖用燃煤锅炉的运行经济性分析

根据我国国情,北方地区的冬季采暖仍然以燃煤为主.针对前段时期兴起的以煤粉炉替代层燃炉作为冬季供暖锅炉有利于节能和环保的说法,以58 MW燃煤热水锅炉为例,从设备基建投资、能源综合利用率、运行经济性等方面对煤粉炉和层燃炉进行了分析比较,结果表明,无论从燃料的选择范围、运行经济性、维修保养还是从供热负荷适应性和运行安全性角度来说,就应用于冬季采暖的锅炉而言,层燃炉仍优于煤粉炉.

Economic Analysis of Winter Heating with Coal-fired Boiler

According to the situation of our country, it was still the priority of using coal for winter heating in north China. Based on the earlier idea that it was helpful to energy saving and environmental protection by replacing grate-fired boiler with pulverized-coal boiler for winter heating, the comparisons were made by taking 58 MW coal-fired hot water boiler as an example, in terms of equipment and basic construction investment, comprehensive energy utilization degree, economy of running, and so on. It was found that the grate fired boiler was superior to pulverized-coal boiler for winter heating in the respect of fuel selection, economy of running, maintenance, heating load adaptability and running safety.
