Smoke bending circulation type multi-water jacket energy saving heating furnace

Abstract

The invention relates to a flue gas bending circulating type multi-water jacket energy-saving heating furnace. An inner shell is arranged inside the outer shell, and outer liquid channels formed in the outer shell and the inner shell are respectively connected with the liquid inlet and the liquid outlet on the outer shell, An inverted liner is arranged at intervals inside the inner shell, the inner liquid channel arranged inside the inner liner is connected with the outer liquid channel, and the space enclosed by the inner edge of the inner liner is connected to the space provided on the outer shell for installing the burner. The mounting holes are connected. In the present invention, the flue gas can quickly heat the heat transfer fluid after the bending cycle, and the heating efficiency is high. At the same time, the combustion agent uses alcohol hydrocarbon fuel, which is pollution-free after combustion, and the environment is clean. The control loop of the temperature controller and the temperature sensor is added to make the The heating circuit automatically heats up, saving fuel and reducing costs.

Description

technical field [0001] The invention belongs to the technical field of energy-saving and environment-friendly improvement of traditional boiler structures, in particular to a flue gas bending and circulating multi-jacket energy-saving heating furnace. Background technique [0002] Boiler is a kind of energy conversion equipment. The energy input by external equipment to the boiler includes chemical energy and electric energy in fuel. The boiler outputs high-temperature water with a certain temperature. These high-temperature water enter the radiator or hot water storage of the user terminal through pipelines. In the pool, the indoor heating or domestic hot water supply is realized. The chemical energy mentioned above is mainly wood, coal, fuel oil and gas. When wood and coal are burned, a large amount of pollutants such as smoke, sulfur nitrogen, carbon dioxide and slag will be produced. These smoke dust will cause pollution when discharged into the air. The slag needs Regu...

Problems solved by technology

The chemical energy mentioned above is mainly wood, coal, fuel oil and gas. When wood and coal are burned, a large amount of pollutants such as smoke, sulfur nitrogen, carbon dioxide and slag will be produced. These smoke dust will cause pollution when discharged into the air. The slag needs Regular cleaning and stacking also cause some pollution to the environment. Fuel and gas are relatively less pollutants, but most of the existing boilers use direct-fired structures, and the heat absorption rate of fuel and gas combustion is low, resulting in Waste of energy, so some manufacturers have developed boilers with spiral flue or multi-stage combustion structure. The former spiral flue is a closed structure, which is difficult to clean, while the latter has a complex structure, larger floor space, and higher cost.
