In order to maximize the utilization rate of steam heat energy and reduce indirect carbon emissions in the production of plasterboard, the cascade utilization of steam is essential. Based on the existing production line of plasterboard with an annual output of 30 million square meters, this paper optimizes the step utilization process of steam in the drying system. The results show that the steam consumption of the optimized drying system is obviously reduced, and remarkable energy saving effect is achieved.展开更多
基于生命周期评价方法,采用Ga Bi ts软件分析1 m^3定向刨花板(OSB)生产过程中的物料和能源消耗及环境排放。结果表明:酸化效应(AP)、光化学臭氧创造潜力(POCP)和全球气候变暖(GWP 100)是最重要的环境影响类别,分别占总环境影响值的52.1%...基于生命周期评价方法,采用Ga Bi ts软件分析1 m^3定向刨花板(OSB)生产过程中的物料和能源消耗及环境排放。结果表明:酸化效应(AP)、光化学臭氧创造潜力(POCP)和全球气候变暖(GWP 100)是最重要的环境影响类别,分别占总环境影响值的52.1%、23.7%和20.8%;主要环境影响工序为施胶、热压成型和刨片,分别占总环境影响值的28.4%、18.0%和16.8%;而电力和胶黏剂是AP、POCP和GWP100中最关键的清单数据。展开更多
