| Abstract: | In a boiler room in Beijing,a direct-contact flue-gas heat recovery system based on absorption heat pump is designed and applied to recover flue-gas heat of a 29 MW boiler. Measurement analysis shows that the exhaust gas temperature can be reduced to 20~30 ℃, the average amount of heat recovery is 2.67 MW and the average COP of pump is 1.62. And the heating efficiency is increased by 11.54% on average. By using direct-contact flue-gas heat recovery, energy efficiency can be greatly improved. |
