Calculation models for influence of back pressure changes on thermal economy of units;

Based on the mechanics analysis of reheater desuperheating spray used in large scale power units and the partial differential theory and matrix analysis method,an analysis model for calculating the influence of reheater desuperheating spray on power plant s thermal economy has been established through rigorous mathematical derivation.

Empirical research on the heat economy index of thermal power plant;

On heat economy improvement of enterprise-owned thermoelectric power plant;

This paper constructs equations of heat economy on the impact of main steam parameters by strict derivation that based on the partial differential theory.

Based on the combination of the matrix equation,the small disturbance theory and the fundamental equations of thermal efficiency analysis,the internal work and thermal analysis equations are educed,and then the quantitative analysis equations for the system energy saving analysis are built.

By strict mathematical deduction,it is being proven that the influence of steam extraction pressure loss on a unit s thermal efficiency is equivalent to the linear superposed effects on efficiency,caused by relevant heaters out flowing feed and drain water enthalpy variation.

Discusses the advantages of building the air-coaling heat-power combination generation unit by a brief review of the development history of it, analyzes the technological feasibility and thermal efficiency of the air-cooling heat and power combination generation unit.
