Controlling the mass ratio to be 2:1:3 when introducing hydrogen, oxygen and water; the water introduction amount is controlled so that the temperature at the time of combustion in the container main body is lower than 450 ℃.
Examples of the invention
The container body of the high-pressure steam generator is a cylinder, the diameter is 125mm, and the height is 65mm. The tubular inlets for the three groups of fluids (hydrogen, oxygen and water) are uniformly arranged on the side wall in a horizontal circumferential orientation, 120 ° apart from each other. The end of the tubular inlet is 30mm from the side wall surface. The tubular steam outlet was arranged at the center of the upper surface of the vessel with the outer end 50mm from the surface and deeper into the vessel by 30mm. A spark plug igniter is arranged at the bottom of the steam outlet pipe fitting and is ignited by electric spark.
An impeller which can rotate around a central rotating shaft is arranged in the container, and the rotating shaft is fixed at the center of the bottom of the cylinder. The impeller is made of carbon steel, and a disc-shaped first alnico magnet is fixedly arranged on the bottom surface. The impeller and the alnico magnet can keep magnetism below 450 ℃.

The motor rotation speed is about 100 revolutions/min. The first AlNiCo magnet and the second AlNiCo magnet are respectively 5mm away from the bottom of the container, and the distance is kept from contact. The container is made of non-magnetic stainless steel to avoid affecting the magnetic drive. The container and the motor are suspended by a bracket system formed by steel square tubes.
When the steam generator is in operation, hydrogen, oxygen and water are introduced into the vessel through three inlets in a mass ratio of 2:1:3, with a total flow of about 10kg/h. Simultaneously, the motor is started to drive the impeller to rotate, and the fluid entering the container is stirred and mixed. And starting the electric spark plug igniter to ignite the mixed fluid. Due to the stirring effect of the impeller, the three working mediums are quickly mixed to perform high-speed combustion, and the speed is close to the premixed combustion speed. Meanwhile, due to the cooling effect of water, the combustion temperature can be controlled to be lower than 450 ℃.
