| Abstract: | The exergy loss coefficient general matrix equation of heaters of regenerative system for the coal-fired power unit was educed.The exergy loss coefficient of heaters of regenerative system of the 600 MW unit have be calculated conveniently by applying the equation and the numerical distribution law of the exergy loss coefficient has be obtained.Compared with traditional methods,the matrix method is simple and was fast calculation speed.The equation can be used for programming the general calculation program,which can be applied to real-time display of the exergy loss coefficient of regenerative system of any unit.The applied method was introduced for reducing energy consumption. |
