Boiler capable of preventing biomass coking

Abstract

The invention discloses a boiler capable of preventing biomass coking. The boiler comprises an air distribution chamber, a chain grate stoker, a steam conveying pipe, a steam manifold, a reducing valve, a pressure gage and steam outlet holes; the air distribution chamber is arranged below the chain grate stoker, and the steam conveying pipe is arranged at the position, above an air distribution bend, of the air distribution chamber, and is fixed to an inclined lateral wallboard of the air distribution chamber through a support; the steam conveying pipe is connected with the steam manifold through the reducing valve; the pressure gage is further installed at the position, in front of the air distribution chamber, of the steam conveying pipe and is located at the front end of the reducing valve; and the steam outlet holes are arranged at the positions, located inside the air distribution chamber, on the steam conveying pipe and face a main burning area of the chain grate stoker, and steam can rapidly reach portions needing to be cooled. The boiler capable of preventing biomass coking includes two steps of feeding burning and steam leading in. According to the method, the air distribution chamber is combined with steam conveying, the structure is compact, using is simple and convenient, biomass burning coking is effectively prevented, the burn-off rate is improved, the cost is reduced, and the method is suitable for industrial production.

Description

technical field [0001] The patent of the present invention relates to the technical field of biomass boiler manufacturing, in particular to a biomass coking prevention boiler. Background technique [0002] With society's increasing demand for energy, fossil fuels as the main source of energy are rapidly declining. Therefore, looking for a renewable alternative energy source has become the focus of widespread concern in society. Biomass energy is an ideal renewable energy source. It has a wide range of sources, and a large amount of industrial, agricultural and forest wastes are produced every year. In the world's current energy consumption, biomass energy consumption accounts for 14% of the world's total energy consumption, ranking fourth after oil, coal and natural gas. Biomass energy is a clean and renewable energy source, CO 2 The emission is close to zero, so the use of biomass energy plays an important role in protecting the environment, improving ecology, and improv...

AI Technical Summary

Problems solved by technology

When biomass is burned, ash is easy to melt and coke on the surface of the grate, which affects the full combustion of biomass

If no measures are taken, the ventilation will be affected and normal combustion will not be possible
