Description
Technical field
The utility model is related to biomass fuel burning technology, especially a kind of biomass powder combined gasification mixing arrangement.
Background technology
For new energy technology as one of the technology most influenced in 21st century development of world economy, the mankind finally will be according to
The energy crisis and problem of environmental pollution that the whole world is solved by the development of New Energy Industry, realize sustainable development.Country encourages
Regenerative resource in, maximum one piece be exactly biomass energy power generation and utilization, China possesses abundant Biomass Energy Resources, according to
Measuring and calculating, China's theory Biomass Energy Resources are 5,000,000,000 tons or so.Currently, the Biomass Energy Resources for exploitation are mainly made a living
Physical obsolescence object, including agricultural crop straw, husk, fuel wood, industrial organic wastes and municipal solid organic waste etc..In face of warp
Like the shadow following the person high consumption, high pollution and resource environment restricted problem in Ji development, in recent years, China is sought for economic growth
Comprehensive transformation of pattern, walks resource efficient development strategy.Circular economy be it is a kind of with resource efficiently utilize and be recycling as core
The heart is that principle meets sustainable using low consumption, low emission, high efficiency as essential characteristic with " minimizing, recycling, recycling "
The mode of economic development of idea of development is the basic change to traditional growth pattern of " mass production, is largely discarded at a large amount of consumption "
Leather.Biomass energy is an important energy, it is contemplated that comes from biomass energy, China to next century, the 40% of world energy sources consumption
There are abundant Biomass Energy Resources, the 70% of fuel in China's rural areas is biomass, and the only every annual amount of straw from village is up to more than 600,000,000 tons.
With the development of economy, the improvement of people's living standards, the reinforcement of environmental protection consciousness, to biomass energy it is reasonable, efficiently open
Hair utilizes, inevitable to be more and more valued by people.
Currently, gasification of biomass is one of the effective ways of clean utilization biomass energy, but existing gasification of biomass
Transformation efficiency it is relatively low under, if not further raising efficiency, be difficult to commercialization, industrialization promotion.
Utility model content
The purpose of the utility model is to overcome above-described the shortcomings of the prior art, provide a kind of biomass powder
Combined gasification mixing arrangement can greatly improve the efficiency of combustion of biomass powder.
In order to achieve the above objectives, the technical solution of the utility model is：Biomass powder combined gasification mixing arrangement, including it is vertical
