摘　　要： 建立由整体黑液气化联合循环发电厂、蒸汽生产车间、蒸煮车间、蒸发站、纸浆干燥车间和苛化车间组成的节能制浆厂模型。模型中,以机械热泵替代多效蒸发器进行黑液浓缩,以黑液气化炉替代传统焚烧炉处理浓黑液,并联合燃气-蒸汽发电机组进行发电生产。通过模型分析和计算机模拟运算,得出以下结论:在接近试验条件下,节能制浆厂每生产1t风干浆,发电厂供电量为6771310kJ,整体制浆厂电能消耗3072435kJ,电能剩余3698875kJ,相当于1027.5kWh。整体制浆厂热能消耗7802235～8318929kJ,需要标准燃煤380.6～405.8kg,该节能制浆厂模型的节能效果显著。 A model of an energy-saving pulp plant comprised of an integrated black liquor gasification combined cycle （IGCC） system, a steam production workshop, a cooking workshop, an evaporation workshop, a drying workshop and a basification workshop were set up and simulated. A mechanical vapor compression（MVC） system substituted the multiple-effect evaporator system to concentrate black liquor and a black liquor gasifier substituted the traditional combustion furnace to dispose the concentrated black liquor, which was combined with a gas-steam generator unit to compose an IGCC system for power in the model. After model analysis and computer simulation calculation, the simulation results indicate under the condition closed to the experiment, for production of i ton of air dry pulp, the net electric output of power plant is 6771310kJ, 3072435kJ of that should be consumed and the surplus was 3698875kJ （equivalent to 102Z5kWh） in the pulp plants. The overall thermal energy consumption of the pulp plants is 7802235-8318929kJ of thermal energy, corresponding to 380.6-405.8kg of standard coal. The energy saving effect with the pulp plant model is remarkable.
