Abstract
The present invention relates to a kind of novel biomass boiler oil preheating and drying fire grate subsystems, including fire grate and face arch, fire grate is equipped between the fire grate and face arch, the fire grate burns for being fallen on the fire grate again after so that biomass fuel is dried and is pyrolyzed by hyperthermia radiation on it.The present invention is first given to biomass fuel on the fire grate between fire grate and face arch, biomass fuel is fallen to again on fire grate by a degree of drying of hyperthermia radiation progress on fire grate and after being pyrolyzed to burn, burning can be more easily and sufficiently complete, biomass boiler suitability of fuel and economy are improved, and avoids generating tar pollution back-end surfaces and bag filter.
Description
Technical field
The invention belongs to biomass boiler technology field more particularly to a kind of novel biomass boiler oil preheating and drying furnaces
Grate system.
Background technique
The environmentally friendly dynamics in China is increasing in recent years, dissipates the appearance for burning coal policy as country phases out, industry combustion
Coal arcola will be banned gradually, and biomass industry arcola will replace coal-burning boiler more and more to be applied.
No matter existing biomass boiler using vibrating-grate stoker, traveling-grate stoker or reciprocal grate, is all by biomass fuel
Material is directly given on fire grate, is frequently present of biological particles and briquetting incomplete combustion, uncombusted heat when boiler is in big load
Lose big problem；Bulk cargo is being used, boiler combustion temperature is low when biomass moisture is bigger than normal, it is bad to burn, while generating a large amount of
Tar pollution back-end surfaces bag filter a series of problems, such as, make biomass boiler application by severely restricts.
Summary of the invention
It is existing to solve the object of the present invention is to provide a kind of novel biomass boiler oil preheating and drying fire grate subsystem
Biomass boiler fuel tolerance is poor, less economical and generate asking for tar pollution back-end surfaces product and bag filter
Topic.
The present invention provides a kind of novel biomass boiler oil preheating and drying fire grate subsystem, including fire grate and face arch,
Between fire grate and face arch be equipped with fire grate, fire grate for make biomass fuel be dried on it by hyperthermia radiation and heat
It falls on the fire grate and burns again after solution.
Further, which further includes for the bio-fuel on fire grate to be pushed to the feed device on fire grate.
Further, which further includes the feed bin above fire grate.
Further, fire grate is vibrating-grate stoker, traveling-grate stoker or reciprocal grate.
According to the above aspect of the present invention, by novel biomass boiler oil preheating and drying fire grate subsystem, biomass fuel elder generation
It is given on the fire grate between fire grate and face arch, biomass fuel is made to be carried out certain journey by hyperthermia radiation on fire grate
It falls on fire grate and burns again after the drying and pyrolysis of degree, burning can be easier and sufficiently completely, improve biomass pot
Furnace suitability of fuel and economy.
The above description is only an overview of the technical scheme of the present invention, in order to better understand the technical means of the present invention,
And can be implemented in accordance with the contents of the specification, the following is a detailed description of the preferred embodiments of the present invention and the accompanying drawings.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of novel biomass boiler oil preheating and drying fire grate subsystem of the present invention.
Specific embodiment
With reference to the accompanying drawings and examples, specific embodiments of the present invention will be described in further detail.Implement below
Example is not intended to limit the scope of the invention for illustrating the present invention.
Join shown in Fig. 1, present embodiments provides that the present invention provides a kind of novel biomass boiler oil preheating and drying furnaces
Grate system, including fire grate 1 and face arch 2 are equipped with fire grate 3 between fire grate 1 and face arch 2, fire grate 3 is for making biomass fuel
It falls on the fire grate and burns again after being dried and be pyrolyzed by hyperthermia radiation on it.
Novel biomass boiler oil preheating and drying fire grate subsystem provided in this embodiment, is first given to biomass fuel
On fire grate between fire grate and face arch, carry out biomass fuel on fire grate by hyperthermia radiation a degree of
It falls on fire grate and burns again after dry and pyrolysis, burning can be easier and sufficiently completely, improve biomass boiler combustion
Expect applicability and economy, and avoids generating tar pollution back-end surfaces and bag filter.
In the present embodiment, which further includes for the bio-fuel on fire grate 3 to be pushed to the feeding on fire grate
Device 4.
In the present embodiment, which further includes the feed bin 5 above fire grate.
In the present embodiment, fire grate 1 can be vibrating-grate stoker, traveling-grate stoker or reciprocal grate.
The above is only a preferred embodiment of the present invention, it is not intended to restrict the invention, it is noted that for this skill
For the those of ordinary skill in art field, without departing from the technical principles of the invention, can also make it is several improvement and
Modification, these improvements and modifications also should be regarded as protection scope of the present invention.
