自然通风方式在火力发电厂主厂房通风系统中的应用

The Application of Natural Ventilation Method in The Ventilation System of Firepower Plant’s Main Workshop

结合工程进行自然通风计算,提出为了简化计算,完全可用中和界面在进排风口的中心面上计算的方法取代传统的假想压力法。主厂房采用自然进风、自然式屋顶通风器排风的方案,在合理的气流组织设计的前提下,不仅经济实用,而且能保证其通风效果良好。

A practical project was used as an example for calculating of natural ventilation, Drawing conclusions that among the natural ventilation calculating, for predigesting purpose, it is feasible that the universal calculating method of supposed pressure is replaced by that of using the middle interface， It is economical adopting the ventilation method of natural air intake and exhaust through the roof ventilators for the main workshop of the firepower plant， It can assure kind ventilation effect through the design of reasonable airflow organizing。
