Efficiency of steam generation in a hydrogen-oxygen steam generator of kilowatt-power class

The article presents the results of experimental studies and optimization of the processes of mixture formation, combustion, and steam generation in a kilowatt power-class, experimental, hydrogen-oxygen steam generator. The optimal design of the mixturing element and the combustion chamber for their failsafe operation and minimal hydrogen content in the generated steam is determined. The influence of the pressure in the evaporation chamber and of the generated steam temperature on the completeness of hydrogen combustion is studied. The results of multiregime tests of the hydrogen-oxygen steam generator at a power of up to $200$ kW are presented.
