摘　　要：通过对不同型式的新建或改造后的机力通风冷却塔热力性能试验的结果认为 ,大部分机力通风冷却塔存在风机风量不足 ,塔内配风不合理 ,除水器冬季飘滴严重等问题 ,对此给出了解决建议。可供石化、电力行业今后设计。Thermal performance tests for various types of newly built or retrofitted mechanical draft cooling towers have been made, it is considered from obtained results that some problems, such as insufficient air-blast capacity of ventilators, irrationable air distribution in the tower, and serious droplet-floating from dewaterers in winter season etc., are existing in most mechanical draft towers. Hence, some recommendations for solving said problems are given, providing useful reference for designing and retrofitting mechanical draft towers in the future for petro-chemical and power industries.
