摘要:

以广东地区某燃煤电厂封闭式锅炉房为例,利用CFD软件对锅炉房4种不同通风工况下的热环境进行了模拟,并对模拟结果进行了对比分析,得出了最优的设计方案。结果表明,夏热冬暖地区封闭式锅炉房采用自然通风方式具有一定的可行性,可以通过优化锅炉房通风设计达到满意的通风效果。

Abstract:

Taking a closed-boiler room of a coal-fired power plant in Guangdong as an example, simulates the thermal environment of the closed-boiler room under four different ventilation conditions using CFD software, compares the simulation results, and obtains the optimal design scheme. The results show that natural ventilation design is feasible for closed-boiler room in hot summer and warm winter zone, and the satisfactory result can be achieved through optimizing ventilation design for boiler rooms.
