Optimal thermalization coefficient of combined heating and power-district heating system based on relative primary energy saving rate

Taking the maximum relative primary energy saving rate as the objective function, proposes a new calculating method for the optimal thermalization coefficient, and establishes a mathematical model for dual-condensable gas heating and cogeneration units. Compared with the conventional method which based on coal savings, the relative primary energy saving method does not involve the coal consumption for heating and generation of combined heating and power plants which is controversial, and the parameters used in relative primary energy saving method are more seasonable on thermodynamics and easier to use in practice.
