Biomass particle fuel gasification combustion normal-pressure water boiler

Abstract

The invention discloses a biomass particle fuel gasification combustion normal-pressure water boiler. The biomass particle fuel gasification combustion normal-pressure water boiler comprises a boilerbody, a spiral feeding device, a fire grate and a flue. A feeding port of the boiler body is connected with a discharging port of the spiral feeding device. The fire grate is arranged at the bottom ofthe boiler body. The flue is arranged at the upper portion of the boiler body. The biomass particle fuel gasification combustion energy-saving and environment-friendly normal-pressure water boiler which adopts biomass particles as fuel, and is efficient, capable of saving energy, low in pollution, capable of achieving zero emission, safe and environment-friendly is disclosed and provided.

Description

technical field [0001] The invention relates to the technical field of biomass briquette fuel boilers, and more specifically relates to an atmospheric pressure hot water boiler for gasification and combustion of biomass particle fuels. Background technique [0002] Biomass energy is the fourth largest energy source other than coal, oil, and natural gas. Biomass is a clean low-carbon fuel with low sulfur and nitrogen content and a small ash content, so after combustion, SO 2 , NO 2 The emission of dust and dust is much smaller than that of fossil fuels, and the greatest contribution of biomass to the ecological environment lies in its CO 2 The characteristic of zero emission is a kind of clean energy that is both environmentally friendly and recyclable.

AI Technical Summary

Problems solved by technology

[0003] At present, when the biomass boiler with fixed grate burns straw pellet fuel, it is easy to slagging in the furnace, which requires frequent shutdown and manual cleaning, which cannot run continuously, insufficient combustion, and low thermal efficiency.

[0004] The feeding design of modern traditional machine-fired boilers is in front of the grate, and the fuel in the hopper is in direct contact with the grate. When burning biomass fuel, due to its high volatile content and low ignition point, it is easier to ignite and burn. When the adjustment is not correct, the flame in the furnace will backfire and burn into the hopper, which will waste fuel and easily cause fire.
