FIELD: heating systems.
SUBSTANCE: invention refers to industrial and public heat engineering, and namely to heat supply, and can be used in low-power hot water boilers. Hot water boiler furnace includes hopper fuel supply system, air supply system and ash disposal system with ash discharge opening; at that, grates of full supply system are made at least in the form of four in-series and overlapped hinged transverse rows of grates, from which, for example uneven ones are mounted on rod and kinematically connected drive and even ones are rigidly connected to steady furnace bottom; on external surface of grates at least one protrusion is made; at furnace bottom an ash discharge opening is made, which is provided with hinged pendulum-type grate with counterbalance. At that, furnace is also equipped with air supply channel to hopper fuel outlet zone.
EFFECT: simplifying hot water boiler design and providing furnace operating reliability.
