The invention discloses a boiler flue gas power generation device, which comprises a power generation shell body and a heat recovery shell body, wherein the lower part of the heat recovery shell body is connected to a chimney; the outer surface of the heat recovery shell body is provided with heat insulation cotton, the heat recovery shell body internally provided with a lower part cavity body and an upper part cavity body, a plurality of parallelly-arranged gas ducts are arranged between the upper part cavity body and the lower part cavity body, the gas ducts are connected with internal empty cavies of the upper part cavity body and the lower part cavity body, a heat collecting cavity is formed between every two adjacent gas ducts, and the heat collecting cavities are connected with one another through a water inlet pipe and a water outlet pipe; the inner wall of each heat collecting cavity is provided with a plurality of arc-shaped projections, and a protruding radian of the arc top is 2.65; and the power generation shell body is a spherical shell body, and is internally provided with a thermal expansion airbag. The boiler flue gas power generation device has the advantage of being capable of overcoming disadvantages in the prior art, and being reasonable and novel in structure design.
Description
technical field [0001] The invention relates to a boiler flue gas power generation device, which belongs to the field of environmental protection. Background technique [0002] The two major losses in thermal power plants are cold source loss and exhaust heat loss. The exhaust heat loss is the largest among all heat losses of power plant boilers, and the exhaust heat loss of modern power plant boilers is generally about 4% to 8%. An important factor affecting the heat loss of exhaust gas is the exhaust gas temperature. However, the existing recovery device will lead to the existence of waste heat, and the recovery is not comprehensive, and there is a lot of waste in the recovery of waste heat. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the technical problem to be solved by the present invention is to provide a boiler flue gas power generation device, which absorbs the heat of the boiler flue gas and then generates electricity through ...
