Energy-saving Analysis Based on the Specific Consumption Theory for Large Coal-fired Power Units

The specific consumption theory is applied to model and analyze the main equipment and steam flow of large coal-fired power unit at different operating loads, based on the First and Second Thermodynamic Laws. A 600MW subcritical coal-fired power generating unit is selected as the research object to analyze the energy consumption distribution at different loads, listing the main equipment of higher energy consumption rates. The results indicate the energy-saving potential of the effects of influencing the energy consumption rates. The research also puts forward the directions of optimizing and reforming to reduce energy consumption.
