With the labyrinth leakage and reclaim system for the coal-fired power unit research object, on the basis of the heat equivalent enthalpy drop method the theory, after rigorous mathematical analysis and derivation, educing the matrix model of account and analysis of the labyrinth leakage and reclaim system for the coal-fired power unit. The type in a matrix format, between the model structure and thermal systems is one-to-one relationship. Application testing show that the calculation is simple and high universality, can be applied to the analysis of different types of units and a variety of different units working conditions. More applicable to a computer with mathematical model,the achievement of the Power Unit energy consumption of great theoretical significance.
