烧爱基巴斯多斯基煤的汽包锅炉运行时,过热蒸汽温度经常超过计算值。为保证额定汽温只得成倍提高喷水量和割除部分过热器受热面。如БК3-320锅炉低温过热器受热面从1450米~2减少到580米~2。为摸清超温的原因,曾在БК3-320锅炉上全面地研究了炉膛和对流过热器的换热。БК3-320-140-2锅炉蒸发量320吨/时,汽压140公斤/厘米~2,汽温570℃,П型布置。炉室容积1510米~3,炉膛受热面893米~3。八只扰动式燃烧器分二排布置在前墙上。带
Overheating steam temperatures often exceed calculated values when operating a drum boiler running on Ikibastoski coal. In order to ensure that the rated steam temperature has only doubled the amount of water spray and cut off part of the superheater heating surface. Such as БК3-320 boiler low temperature superheater heating surface from 1450 m ~ 2 reduced to 580 m ~ 2. To find out the reason for over-temperature, in БК3-320 boiler on a comprehensive study of the furnace and convection superheater heat transfer. БК3-320-140-2 boiler evaporation 320 tons / hour, steam pressure 140 kg / cm ~ 2, steam temperature 570 ℃, П-type layout. Furnace chamber volume of 1510 m ~ 3, the furnace heating surface 893 m ~ 3. Eight disturbing burners are arranged in two rows on the front wall. band
