| Abstract:Large pulp and paper enterprises were large users of heat and electricity. In order to save energy and meet the production needs， it was necessary to construct cogeneration projects to provide steam and electric energy for production. The common cogenerations of coal-fired boiler， gas-fired boiler and gas-steam combined cycle cogeneration were introduced in this paper. Aiming at the three cogeneration modes， the cost calculation method was established， and the calculation curves of heating and power supply were obtained by modeling and calculating different unit project investment and different fuel prices， which could provide reference for the choice of cogeneration modes. |
