Energy Efficiency Analysis of Preheating Boiler Feedwater System with Air Source Heat Pump

Abstract:

In order to solve the problems of high energy consumption and serious pollution caused by boiler rooms, this paper mainly introduces a preheating boiler feedwater system with air source heat pump, which includes an air source heat pump, plate heat exchanger and so on. The calculating results show that the system can save coal of 35.67 tons, reduce emissions of carbon dioxide of 94.90 tons per year and would recover all the investment eight years later; It has been proved that the system has better characters such as energy-saving, economical efficiency and so on; it is worth popularizing widely in the city as Lanzhou city with heaviest air pollution.
