HEAT GENERATOR Russian patent published in 2005 - IPC

FIELD: heat power engineering.

SUBSTANCE: heat generator comprises housing which receives combustion chamber with fire bottom and branch pipes for supplying fuel gas and air and mixing chamber with openings for injecting vapor or water arranged coaxially to provided a ring space between the housing and combustion and mixing chambers. The space receives water boiler with ring collectors and branch pipes for supplying water and withdrawing hear carrier. The branch pipes for supplying fuel gas and air enter the chamber for preparing combustible mixture. The combustion chamber is made of a vortex chamber with tangential supplying of combustible mixture and Laval nozzle at the outlet. The fire bottom is provided with a cylindrical steam boiler mounted coaxially to the combustion chamber and provided with a device for supplying water and supersonic nozzle at the outlet, the exit of the nozzle being downstream of the minimum cross-section of the Laval nozzle. The device for supplying water to the steam boiler is centrifugal and provided with a check valve-controller at the exit. Water and vapor are injected into the mixing chamber through the ejecting nozzles.

EFFECT: reduced sizes and mass and simplified heat carrier control.
