摘要
为确保氢和氧稳定、完全地燃烧 ,采用临界喷管控制氢氧的质量流率 ,以及同轴环向的预混方式。实验结果表明 :改变氢氧质量流率或尾喷管临界截面积可调节燃气总压 ,建成结构简单且造价低廉的高焓水蒸汽发生器。
Critical nozzles are used to control the mass flow of hydrogen and oxygen, to keep the ratio of hydrogen and oxygen to be stoichiometrical. The mixing uniformity of co-axial hydrogen and oxygen jets satisfies the requirement of stable combustion well. The results of the experiments show that changing the mass flow of hydrogen and oxygen or adjusting the critical section area of the nozzle can change the gross pressure of the high enthalpy gas in the combustion chamber. These two kinds of methods can be used to build the high-enthalpy steam generator with simple structure and inexpensive cost.
