FIELD: heat power engineering. ^ SUBSTANCE: heater comprises cylindrical housing provided with fan at its face, fan motor mounted inside the housing downstream of the fan impeller, furnace coaxially mounted inside the housing with a spaced relation to its wall, swirler made of a disk with cuts and inclined blades and mounted on the face of the furnace from the side of the fan, and burner mounted in the furnace and connected with the fuel source. The furnace is made of Venturi tube whose neck is perforated. The deflecting blades are mounted in the space between the housing and furnace for permitting rotation. ^ EFFECT: enhanced efficiency. ^ 1 dwg |
