MOBILE THERMOGENERATOR Russian patent published in 2002 - IPC

FIELD: heat-power engineering; mobile thermogenerators for heating rooms with hot air. SUBSTANCE: mobile thermogenerator has body secured on truck with exhaust pipe and gate valve and air supply and discharge passage; air supercharger is mounted inside this body; thermogenerator is also provided with combustion chamber fitted burner unit, heat exchanger with central passage and fuel main; body with exhaust pipe is mounted on truck in vertical position; central passage is formed by circular row of vertical tubes which are used for communication of combustion chamber with exhaust pipe; combustion chamber is bounded with circular cavity in its upper portion which is formed by two concentric cylinders mounted above burner unit. Outer concentric cylinder is connected with body by means of diaphragm for compensation of thermal elongation of tubes and sealing-up the cavity of combustion chamber. Burner unit is toroidal in shape for organization of steady combustion of fuel and ensuring complete combustion. Provision is made for avoidance of accumulation of fuel-and-air mixture in thermogenerator which ensures its safe operation. Heat transfer is enhanced due to availability of vertical bank if tubes around which transversal air flow passes. EFFECT: simplified construction; enhanced operational reliability. 2 cl, 1 dwg
