燃具检验热负荷的确定

Determination of Heat Input of the Gas Appliance in Detecting

本文从气体通过孔口的流动规律出发,推导了燃具在设计条件和测试条件下所通过燃具喷咀的燃气流量间的关系,提出了燃具检验时热负荷的计算方法,同时分析了本文提出的计算方法与传统的计算方法间的偏差及造成偏差的原因。

Based on the principles of the gas flowing through nozzles, this paper infers the relationship of the gas rate through the range's nozzle between in design conditions and in test conditions. It is put forward a calculating method of the heat input at which a range will be tested. Meantime, the error between the calculating method, put forward in this paper, and the conventional calculating method is analyzed and explained.
