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
