摘要:Efficiency and energy consumption of boiler systems are affected by many factors. Firstly, the idea of boiler system being divided into different level subsystems is put forward, and the evaluation model of boiler efficiency and energy consumption is established. Secondly, analytic hierarchy process (AHP) is used to judge the matrix of the evaluation model’s influence weight on the overall target. The model can be used to guide the energy saving diagnosis and analysis of boiler system. Compared with the key factors, the energy saving potential is analyzed from the aspects of economy, energy saving and environmental protection.
