Abstract

An analysis of the existing methods and schemes of heating the air by combustion products in the tailings of the heating boiler indicates that such measures provide an opportunity to increase the efficiency and reliability of power plants, as well as increase the efficiency of boiler plants. This paper considers the results of the study of the economic performance of the modernized RAH-98 boiler TGMP-314 A 300 MW on natural gas in the range of load variation of the power unit 160–260 MW and on the fuel oil in the range of load variation of the power unit 200–260 MW. Experiments were carried out at a stable mode of operation of the boiler in two stages: for the off and for the included scheme of suction environment from the seals of RAH. The average increase in the efficiency of the boiler is 0.35 % gross during operation of the boiler, both on natural gas and on fuel oil in the specified range of loads. Absorption of air in RAH for loads of the power unit 160–260 MW for the included circuitry is reduced by 7 % on average compared to the disconnected circuit. Bibl. 10, Fig. 5.
