HEAT TRANSFER ANALYSIS AND THERMAL EFFICIENCY CALCULATION OF GAS-FIRED SUCTION HEAT WATER BOILER

摘要：

The thermal efficiency is an important target of performance of the boiler. Efficiency of gas-fired vacuum hot water boiler is researched by the heat transfer calculation and experimental mensuration. The methods of forward balance and inverted balance are applied to calculate the efficiency. The thermal efficiency calculated by the method of forward balance is 91.7％ and 92.8％ by the method of inverted balance respectively . The error is 1.1％, and it is accord with the standard. The research results show that the burning of gas-fired vacuum hot water boiler is enough and the thermal efficiency is above 91％, and the fuel is utilized adequately.
