摘要
Abstract
The coal consumption rates for power generation and the steam turbine heat rates were calculated based on the heat quality method for a 330 MW direct air-cooled power unit with four heating supply schemes, using the extraction steam, the high back-pressure exhaust steam, the absorption heat pump and the electricity driven heat pump for a constant heating supply load. The energy conservation characteristics for the power unit with the four heating supply schemes were also analyzed. The calculated results showed that the direct air-cooled power unit showed higher energy utilization efficiency with heating supply using the high back-pressure exhaust steam or the absorption heat pump than that of using the extraction steam; while the heating scheme using the electricity driven heat pump showed inefficient. However, the optimal operating conditions should be searched for the heating supply using high back-pressure exhaust steam. All of the above analytical results could be reference signification for heating supply schemes selection and energy conservation reconstruction for power plants.关键词
