| Abstract: | Based on constant-heat equivalent enthalpy drop method and matrix method,constant-heat equivalent enthalpy drop matrix equation for power unit with double reheat was derived from strict mathematics deduction and demonstration.Using this matrix without power equation and heat absorption equation,the thermal economic analysis of double reheat unit can be completed well.In this way,a new method of thermal economic quantitative analysis was provided,so the scope of application of constant-heat equivalent enthalpy drop method was extended.Through some case calculations,the reliability of the model proved that it is common,accuracy and suitable for computer calculation. |
| Keywords: | power unit with double reheat equivalent enthalpy drop method thermodynamic system thermal economy matrix method |
