A Matrix Method And System Development For Thermodynamic System Analysis In A Power Plant With Double Reheat Cycles

Based on the present coal-fired unit thermal system analysis method, a method of thermal economy analysis of supercritical pressure unit with double reheat cycles was constructed. Compared with the present the supercritical pressure unit with double reheat cycles thermal analysis methods, there is a one-to-one corresponding relationship between the topologic configuration of the matrix equation and actual thermal system configuration, and its matrix element values reflect the thermal parameters of the actual thermal system. The structure and thermal characteristics of the supercritical pressure unit with double reheat cycles thermal dynamic system can be expressed in mathematics conveniently. The paper also developed a software for analyzing the supercritical pressure unit with double reheat cycles thermal efficiency.
