正确地计算出自然循环锅炉在工作时所带水量对加药处理和排污计算很有必要。尤其是蒸发量大、带水量少的舰用自然循环水管锅炉,其每小时产汽量和带水量之比高达25以上,在高负荷时水位下的含汽泡数目甚多,而且工作压力下饱和水的重率和冷态下不同。因此,锅炉工作时带水量和冷态下的迥异。有必要研究这种锅炉在工作时带水量的计算方法。作者曾于1977年2月介绍船用自然循环锅炉在工作时所带水量的计算方法。该方法系根据76型锅炉的原水循环计算书中所载说明。由于原载说明在推导
It is very necessary to calculate correctly the water quantity brought by the natural circulation boiler at the time of working for dosing and sewage calculation. In particular, ships with large evaporation and less water have natural circulation water tube boilers with a ratio of up to 25 per hour of steam volume and water carrying capacity. At high loads, the number of bubbles contained in the water level is very large, and under working pressure The re-rate of saturated water is different from the cold state. Therefore, the boiler work with water and cold under very different. It is necessary to study the method of calculating the water carrying capacity of such a boiler at work. The author introduced the method of calculating the amount of water carried by a natural circulation boiler for ships at work in February 1977. The method is based on the original boiler water cycle calculation book contained in the instructions. As the original description is derived
