Steam - flue gas heater for flue gas desulfurization, which is characterized in that: in the opening of the adjustable steam inlet valve, steam flow into the heater change, thus changing the heated flue gas outlet temperature, achieve the purpose of energy saving in the prerequisite to meet the emission requirements of the. This equipment solves the controllability of the steam gas heater, has a good energy-saving benefit.
Equipment characteristics:
1, the overall investment is low;
2, in a certain range of temperature controlled;
3, heat utilization efficiency is high, can produce the supercooled water.
