A Method for Non-Reheating Rower Plant Thermal System Analysis-Method of Conversion Cefficient of Heat/Steam Rate

Guo Minchen; Wang Qingzhao; Wei Nan; Wang Jiaxuan (Dept.of Power Engineering,NCEPU,Beijing 100085)  
The two important parameters (conversion coefficients of heat rate,ξ i and steam rate,k i)for analysing thermal system are obtained under the condition of constant output.The quality of turine regenerative steam-drawing can be represented by them.The thermal economy and structure for power plant thermal system can be caculated and improved with them.They are calculated with matrixmethod,that is particularly suitable for computer processing.The principle for computing these two parameters for non-reheating power plant themal system is presented in this paper.A condensing unit of 100MW is taken as an example to show the correctness of the method.
