Abstract:

For the flue gas selective catalytic reduction (SCR) denitrification urea hydrolytic system, the mixed gas at its outlet should have a certain degree of superheat. In order to meet that requirement, this paper introduced a method of using a gasgas heater (GGH) to heat the cold dilute wind and the GGH device has internal flue at outlet of denitrification system, which has some advantages of simple system, small investment, convenient maintenance and obvious energy saving effect. The practical operation effect meets the expected performance requirement and provides reference for similar energy saving transformation project, which has good popularization value.
