FIELD: power industry. ^ SUBSTANCE: outdoor condensation boiler contains blower furnace, main heat-exchanger, direct and reverse lines, circulation pump. Boiler is equipped additionally with two flue ducts with heat-exchangers installed inside them, at that flue ducts are located below chimney outlet of main heat-exchanger and two heat-exchangers are installed inside flue ducts in order to warm up heat carrier by flue gases with subsequent delivery of hear carrier to heat-exchangers. At that each flue duct is equipped with condensate drainage tube located at the base. ^ EFFECT: reduction of heat production costs and improvement of efficiency factor due to use of auxiliary flue ducts. ^ 2 dwg |
