Multi-layer water jacket environmental protection boiler

Abstract

The invention discloses a multi-water jacket environmental-friendly boiler which relates to an environment-friendly boiler for clean burning. The multi-water jacket environmental-friendly boiler is characterized in that the boiler mainly comprises an inner layer water jacket, a middle layer water jacket, an outer layer water jacket and a drum, wherein the inner layer water jacket, the middle layer water jacket and the outer layer water jacket are arranged coaxially and straightly; the inner layer water jacket is arranged in the hollow cavity of the middle layer water jacket, and the outer layer water jacket is arranged outside the middle layer water jacket; the middle layer water jacket is provided with a downward extension section; the inner space of the extension section is formed into a hearth a; the bottom or the side surface of the hearth a is provided with a burner interface; the upper spaces of the inner layer water jacket, the middle layer water jacket and the outer layer water jacket form a hearth b; the drum is arranged in the hearth b; the inner space of the inner layer water jacket is formed into an internal heat channel a; a space between the inner layer water jacket and the middle layer water jacket forms an internal heat channel b; a space between the middle layer water jacket and the outer layer water jacket is formed into a flue gas channel; and a flue gas chamber is arranged below the outer layer water jacket and the flue gas channel. According to the multi-water jacket environmental-friendly boiler, the heating surfaces of the multiple water jackets are large, the heat efficiency of the boiler is high, and the consumption of resources is reduced and the environmental friendliness is realized.

Description

technical field [0001] The invention relates to boiler equipment, in particular to a clean combustion environment-friendly boiler. Background technique [0002] Boilers are necessary equipment for people's life and production. The boilers currently used mainly include fire tube boilers, water tube boilers, water and fire tube combined boilers, and shell boilers. The effective heating surfaces of these boilers are not large, and there are poor heat exchange capabilities and thermal efficiency. Low temperature, high exhaust gas temperature, slow production of steam, etc. Usually, it is necessary to increase the auxiliary heating surface, such as installing a superheater on the upper part or outlet of the furnace, and installing an economizer in the tail flue of the boiler to improve the thermal efficiency of the boiler. . [0003] For a long time, boilers mainly burn solid fuels directly, and there are generally insufficient combustion, low thermal efficiency of boilers, seri...
