在锅炉效率的计算中 ,ASME标准被普遍认同 ,在引进机组的考核验收以及电厂重要热力试验中广泛采用 ,但该标准对测量有较高的要求。德国DIN标准采用统计公式 ,其方法比较简便 ,且与ASME标准计算具有较好的一致性。文中对两者进行了全面的比较 ,并结合ASME和DIN标准两者的优点 ,提出了一种新的锅炉效率计算模型。
In the calculation of boiler efficiency, ASME standards are generally accepted, widely adopted in the inspection and acceptance of imported units and important thermal tests in power plants, but the standard has higher requirements for measurement. The German DIN standard adopts the statistical formula, the method is relatively simple, and has good consistency with ASME standard calculation. In this paper, a comprehensive comparison of the two is made. Based on the advantages of ASME and DIN, a new boiler efficiency model is proposed.
