Circulating condensation boiler

Abstract

The invention discloses a circulating condensation boiler. The circulating condensation boiler comprises a boiler body, the lower side and the upper side of the right end of the boiler body are fixedly connected with a water inlet and a water outlet respectively, the boiler body communicates with the water inlet and the water outlet correspondingly, a gas furnace is installed below the inner partof the boiler body, the outer wall of the left side of the gas furnace is connected to the inner wall below the left side of the boiler body in a sleeving mode, the right end of the gas furnace communicates with the left end of a pressure reducing valve, and the outer wall of the middle of the pressure reducing valve is connected to the inner wall below the right side of the boiler in a sleeving mode. According to the circulating condensation boiler, odor removing for smoke is carried out through two activated carbon plates, filtering impurities in the smoke is carried out through two filter plates, the qualified smoke is exhausted to the atmosphere through a smoke outlet, and the problem that in the using process of the existing circulating condensation boiler, although a condensation type boiler condenses water vapor in the smoke, the harmful substances in the flue gas can be conveniently removed, impurities and odor in the smoke can still bring health problem to people and the atmosphere is solved.

Description

technical field [0001] The invention relates to the technical field of boilers, in particular to a circulating condensing boiler. Background technique [0002] The condensing boiler is to use the efficient flue gas condensation waste heat recovery device to absorb the sensible heat in the tail exhaust of the boiler and the latent heat released by the condensation of water vapor to achieve the purpose of improving the thermal efficiency of the boiler. The condensing boiler can recover the water vapor in the flue gas The amount of latent heat is related to the type of fuel used by the boiler and the outlet water temperature of the boiler. When an ordinary boiler without a condensing recovery device burns natural gas, if the thermal efficiency of the boiler is 90% based on the low calorific value of the fuel, a condensing waste heat recovery device is used. Finally, when the exhaust gas temperature drops to 30-50°C, its thermal efficiency will increase to about 107%. During the...

Problems solved by technology

[0003] The purpose of the present invention is to provide a circulating condensing boiler to solve the problem that the existing circulating condensing boiler proposed in the above-mentioned background technology can be easily removed while the condensing boiler is condensing the water vapor in the flue gas during use. These harmful substances in the smoke, but the impurities and odors in the smoke can still cause health problems for people and the atmosphere
