abstract

Boiler building in power plant includes various types of different equipments. These equipments can be boiler itself and others delivering energy which are acting as heat sources. Moreover, complex piping system to deliver hot steam to turbine and other auxiliary components add additional heat sources and make internal arrangement even more complex. In this study, ventilation analysis is performed to find proper location of openings such as louvers and windows, which ensures desired heat transfer. Various openings provide air passage to reduce stagnation area of high temperature inside enclosed structure. Ventilation analysis is applied to entire internal space of the enclosed structure with standard k-ε model. Opening size of the louver determines amount of air flow which gives direct cooling effect. Different combinations of the louver locations are studied together with size variations to find optimum condition for better ventilation. The location of louver is found as important factor in the ventilation effect. Vertical location change, especially, results enhanced cooling effect which provides effective passive design concept. The opening size of louver is found to have proportional effect on cooling. From the analysis, it is also found that high local temperature can be removed effectively by lowering upper louver location.
