摘要:大型浆纸厂是用热和用电大户,为节约能源、满足生产需要,需配套建设热电联产项目为工艺生产提供蒸汽和电能。本文主要介绍了常见的燃煤锅炉热电联产、燃气锅炉热电联产、燃气-蒸汽联合循环热电联产3种方式。针对3种热电联产方式,建立成本计算方法,对不同单位工程费用、不同燃料价格进行建模计算,得出供热和供电计算结果曲线,为热电联产方式的选择提供参考。
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.
