回转窑预热器的废气温度为250℃以上,排放到大气中时温度在170℃左右,如果不加以利用,这部分热能会白白浪费。太钢复合材料厂本着节能降耗、废气回收的原则,应用纯低温余热回收技术,设置1台烟气余热换热器,可最大限度地利用烟气热量将水加热到供暖温度。
The exhaust gas temperature of the rotary kiln preheater is above 250 ° C and the temperature is about 170 ° C when it is discharged to the atmosphere. If it is not utilized, this part of the thermal energy will be wasted. TISCO composite materials plant in energy saving, waste gas recovery principle, the application of pure low temperature waste heat recovery technology, set up a flue gas waste heat exchanger, the maximum use of flue gas heat to heat the water to the heating temperature.
