The main disadvantage of regenerative air heaters (RAH) is reduced gas confinement. As a result, a significant amount of air leaks into the heater and thus increases heat losses. A method has been proposed and tested, where air induction through radial and peripheral seals of the RAH is directed to the suction pipe of the blast fan for recirculation of flue gases, to increase operational efficiency of a 300 MW boiler unit. The test results indicated the increased efficiency of the boiler under all operating range of loads. The reduction of nitrogen oxides in the flue gases by 30% was achieved.
