Energy saving and consumption reduction of hot blast stove house is a comprehensive project, and there is still much work to be done. Feasible measures for energy saving and consumption reduction of hot-blast stove house can be taken from many aspects, such as energy-saving transformation of equipment, auxiliary machine, thermal pipeline and management of hot-blast stove house, selection of new energy-saving hot-blast stove, adoption of frequency conversion regulation and automatic control technology, strengthening heat preservation and maintenance of thermal pipes, and popularization of direct burial of thermal pipes. Comprehensive treatment of condensate and sewage to improve recovery rate
Attention should be paid to the insulation measures for flanges, valves and various pipeline accessories to reduce the heat loss of the whole heating network. "Leakage" is an old problem of heating network. It is necessary to improve the quality of daily maintenance and regular maintenance of heating network, which plays an important role in improving the efficiency of hot blast stove house. 蒸汽经过用热设备后生成的冷凝水水质好，且温度可达60—100℃，但90%以上在用工业热风炉的用户未对冷凝水进行回收，而当废水排掉了。若能对凝结水采用多区段过滤附加锅内加药法进行综合回收利用，不仅减轻了水处理的负荷，节省了水处理费用，同时提高了给水温度，降低了燃料耗量，通常给水温度每提高6℃，可节约燃料1%。节能可达10%～12%。为降低热风炉排污热损失，应加强热风炉给水品质控制，并尽可能减少热风炉排污量，同时应采取措施回收排污热量。热风炉房热力系统的排污量应控制在5%以下，最好为2%左右。此外，可采用加装排污扩容器及换热器来回收部分排污热量，以起到节能降耗的作用。
The quality of condensate water produced by steam through heat equipment is good, and the temperature can reach 60 - 100 C. However, more than 90% of users in industrial hot blast stoves do not recycle the condensate water, but when the wastewater is discharged. If the condensate water can be comprehensively recovered and reused by multi-section filtering and adding medicine in the additional pot, not only the load of water treatment can be reduced, the cost of water treatment can be saved, but also the temperature of water supply can be increased and the fuel consumption can be reduced. Usually the fuel can be saved by 1% for every 6 C increase in the temperature of water supply. Energy saving can reach 10%-12%. In order to reduce the heat loss of hot blast stove discharge, the quality control of hot blast stove feed water should be strengthened, and the discharge of hot blast stove discharge should be reduced as much as possible. Meanwhile, measures should be taken to recover the heat of discharge. The discharge volume of the thermal system of the hot blast stove house should be controlled below 5%, preferably about 2%. In addition, some heat from sewage can be recovered by installing expanding containers and heat exchangers to save energy and reduce consumption.
