FIELD: heating systems. ^ SUBSTANCE: heating boiler includes a furnace, a recuperative heat exchanger, a gas duct and a damper. The boiler is equipped with an additional regenerative heat exchanger located immediately after the furnace in front of recuperative heat exchanger in the direction of movement of combustion products. Regenerative heat exchanger is made in the form of a loose ceramic, metal or other head piece. Head piece of regenerative heat exchanger is arranged on the grid which is water-cooled. The housing of regenerative heat exchanger is water-cooled and hydraulically connected to recuperative heat exchanger. ^ EFFECT: high efficiency of the heating boiler, simplifying the design and the service of the heating boiler, and providing considerable heating lifetime. ^ 1 dwg |
