FIELD: heating.
SUBSTANCE: invention designed for steam heating and can be used in heat-and-power engineering. A straight flow boiler includes a case with combustion chamber and a burner, a steam supply chamber, low temperature inlet pipe, a steam heating tube, installed within the combustion chamber frames, a low temperature steam outlet pipe. The boiler designed with ability to generate low temperature steam form feeding water, filling in steam supply chamber, with its following supply to low temperature steam inlet pipe for the secondary heating at running through the heating tube with outside withdrawal through high temperature steam outlet pipe at high temperature steam faze. The boiler includes a ring water tank, installed in the case bottom part, an exhaust pipe, located immediately under the ring water tank and connected to the combustion chamber through exhaust tubes, which go through the ring water tank and vertical water injection tubes for feeding water heating, routed to the top from the ring water tank. Vertical water tubes upper ends connected to the steam supply chamber, which located in the upper part of the case.
EFFECT: performance factor the boiler heat radiation increase.
