Biomass chain boiler

Abstract

The invention discloses a biomass chain boiler. The biomass chain boiler comprises a boiler body provided with a feed port. An upper boiler barrel, a lower boiler barrel, a hearth, a combustion chamber, a front arch, a back arch and a chain grate stoker are arranged in the boiler body. The front end of the upper boiler barrel stretches to the front side of the front end of the lower boiler barrel. The upper boiler barrel and the lower boiler barrel are connected through a convection bank, and the combustion chamber is formed between the upper boiler barrel and the lower boiler barrel. The hearth is located on the lower side of the front of the upper boiler barrel and located on the front side of the combustion chamber and is communication with the combustion chamber. A throat is formed between the front arch and the back arch, and located under the hearth and on the front side of the lower boiler barrel. The chain grate stoker sequentially penetrates through the feed port, the lower portion of the front arch, the lower portion of the back arch and the lower portion of the lower boiler barrel from front to back. The biomass chain boiler can make biomass briquette fully combust and improve combustion efficiency.

Description

technical field [0001] The invention relates to a biomass chain boiler. Background technique [0002] With the increasing human demand for energy, the shortage of mineral energy or conventional energy and the serious environmental pollution caused by it, the emissions of NOx, SOx, and soot particles from biomass energy are far lower than conventional energy, and carbon dioxide is close to Zero emissions, biomass energy is gradually being placed in an important position for sustainable development. At present, my country's straw as energy utilization methods mainly include: direct combustion, solidification molding, biogas technology, pyrolysis and vaporization. Due to the shortcomings of general crop straws such as looseness, low density, and low calorific value per unit volume, it is inconvenient to use as fuel. Biomass briquette fuel technology should be developed rapidly, but biomass fuel is directly burned in coal-fired boilers. There is a large waste of energy, as an ...

Problems solved by technology

Due to the shortcomings of general crop straws such as looseness, low density, and low calorific value per unit volume, it is inconvenient to use as fuel. Biomass briquette fuel technology should be developed rapidly, but biomass fuel is directly burned in coal-fired boilers. There is a large waste of energy, as an important part of the application process of biomass briquette fuel: the design and production of biomass briquette fuel boilers, there is a misunderstanding of blindly imitating coal-fired boilers, but the combustion equipment after transformation still has combustion efficiency and Outstanding problems such as low thermal efficiency, decreased output and working fluid parameters, and high combustible content in exhaust smoke

my country's biomass briquette fuel boilers are still immature, and there are problems such as insufficient combustion of biomass briquette fuel, resulting in low combustion efficiency
