参数法确定舰船增压锅炉的蒸发量

Parameter method used to measure evaporation capacity of marine supercharged boilers

对于新制造或中修后的蒸汽动力装置的锅炉来说,研究其热平衡、确定其热效率以及检验增压锅炉出力,都必须知道锅炉的蒸发量.针对传统方法确定锅炉蒸发量的不足,运用流体力学基本原理,用参数法推出确定舰船增压锅炉蒸发量的计算公式.只需要在稳定工况下通过记录蒸汽参数(pk和pgr、tgr及B),并在计算机上编程计算即可得到蒸发量Dk.

For the new-made or after-medium-repair steam boilers, it is important to know the evaporation capacity in order to study their heat balance, to measure their thermal efficiency and to examine their output. By using the basic principle in fluid mechanics and parameter method, this paper puts forward the formula for measuring the evaporation capacity of the supercharged boiler.
