FIELD: power engineering.
SUBSTANCE: in a steam generator comprising a vessel, an igniting device, a unit to supply low-enthalpy water steam, an outlet part, according to the invention, a nozzle for hydrogen and oxygen mixture supply is installed along the axis of the vessel, and the unit of low-enthalpy water steam supply comprises a nozzle of low-enthalpy water steam supply, an end wall, a circular channel, a partition with holes arranged along the concentric circumference relative to the axis of the vessel and is located relative to the nozzle of hydrogen and oxygen mixture supply so that the steam generator vessel is simultaneously a chamber of combustion and mixing. The specified technical result is also achieved by the fact that in the method to produce high-temperature water steam, including combustion of hydrogen and oxygen in the stoichiometric ratio and mixing of combustion products with a ballasting component, according to the invention, the mixture of hydrogen and oxygen is supplied for combustion, the ballasting component is a low-enthalpy water steam, supply of the mixture of hydrogen and oxygen is carried out along the axis of the vessel, supply of low-enthalpy water steam - via holes arranged along the concentric circumference relative to the axis of the vessel, combustion of the hydrogen and oxygen mixture is carried out simultaneously with mixing in the flow of water steam.
EFFECT: simplified design of a device and a method, which results in simplicity of manufacturing and operation, in reduction of mass and dimensions of a device, in reduction of hydraulic resistance of a process.
