我厂汽鍋原设計为烧煤的,在爐前有鼓风机,爐后有抽风机,而我厂已将鍋爐改为烧油,没有鼓风设备,以致造成爐膛抽力不足,爐火在爐膛內阻力过大,部分形成涡流,燃料燃烧不完全,最終使蒸发能力大为降低。此外,在烟道出口烟囱进口处,防火器的篩口过小,烟灰把防火器篩口几乎全部堵塞,使烟道气不暢通,影响汽鍋的蒸发效率。由于以上两个原因,严重影响爐膛溫度不能提 I plant the original design of the boiler for burning coal, in front of the furnace blower, exhaust fan after the furnace, and I have changed the boiler plant to burn oil, there is no blast equipment, resulting in inadequate pumping capacity, the fire in the furnace Internal resistance is too large, part of the formation of eddy currents, fuel combustion is not complete, and ultimately make the evaporation capacity is greatly reduced. In addition, at the inlet of the chimney exit chimney, the sieve of the fire extinguisher is too small, and the chimney blocks the fire sieve almost completely, which makes the flue gas unblocked and affects the evaporation efficiency of the boiler. Due to the above two reasons, a serious impact on the furnace temperature can not mention
