FIELD: power engineering.
SUBSTANCE: invention relates to power engineering and can be used for production of steam in a wide range of temperatures for different consumers. Steam generator comprises two steam generation chambers, one of which is equipped with at least one synthetic gas reactor for obtaining medium-temperature and low-temperature steam for conversion of natural gas into higher calorie gas, heating and circulation water chambers, side and ceiling, with protrusions and cavities in the heating wall. Upper wall of the ceiling cavity at the edges is separated from the side wall of the chamber by an annular cavity made in the side wall of the chamber. Output of heated water from side cavity is perpendicular to sidewall. Circulation of water in cavities is ensured by supply of water from below at side cavities and in the center at ceiling cavity. Other chamber for production of any type of steam, including high-temperature steam up to 1500°C is equipped with explosive gas from hydrogen and oxygen. Combustion chamber is closed in hemispherical space of cavity with cooling water with nozzles in upper and lower parts. This combustion chamber is connected to the other combustion chamber. In the lower base of the first combustion chamber a steam receiver is made.
EFFECT: reduced metal consumption, higher efficiency of steam generator.
