Description
Technical field
The present invention relates to boilers, and in particular to a kind of biomass bale packing fuel boiler anti-coking fire grate.
Background technique
In order to handle agricultural crop straw, country, which is advocating always, a few years ago is processed into particle as fuel, still for stalk
Due to the higher cost for the pellet that stalk is processed into, biomass granule fuel is caused not have advantage in cost, influences particle combustion
The popularization of material.At present China again widely popularize will bale packing stalk directly as the biomass bunch burning boiler of fuel, but it is biological
In combustion process, that there is no conventional fuels is so simple as fuel for matter bale packing, due to containing sugared part and mud in the biomass such as stalk
Soil, can generate thick coking in boiler when high-temp combustion, coking hangs over and is difficult to clean up on the heated tube wall of boiler.Coking can also
Unburned straw bonding is got up, if will seriously affect these stalks without broken and burn away in boiler.Boiler
Coking on heated tube wall can also be cumulative, can seriously affect boiler heat exchange, boiler thermal efficiency is lower and lower can make boiler without
Method normal use, it is last even thoroughly to scrap.
Summary of the invention
Biomass bale packing burning can be formed by coking the object of the present invention is to provide one kind and be crushed slagging prevention,
To guarantee biomass normal combustion in boiler, advantageously ensures that the normal use of boiler and play the biomass of boiler thermal efficiency
Pack fuel boiler anti-coking fire grate.
The technical solution of the invention is as follows: it includes several fire grate bars, transmission device and decelerator, each fire grate
The both ends of the parallel arranged in parallel of bar, each fire grate bar are rotatably installed in respectively on the side wall of boiler two sides, and each fire grate bar is located at pot
Position between furnace two sidewalls offers several broken burnt teeth being projected into outside fire grate bar, each furnace along the axially-spaced of fire grate bar
The same end of tier pole same axial extends respectively into outside boiler side walls, and transmission device is mounted on deceleration electric arbor and each fire grate bar
It extends between the end outside boiler, decelerator rotation drives each fire grate bar to rotate by transmission device.
The solution have the advantages that: biomass bale packing burning can be formed by coking and be crushed slagging prevention by it,
To guarantee biomass normal combustion in boiler, advantageously ensures that the normal use of boiler and play boiler thermal efficiency.It is tied
The simple low cost of structure makes biomass and coking generate rolling on fire grate, so that biomass be disturbed using rotational structure
Come in order to smoothly burning.The work of its continuous rotation can be bonding to fire grate with slagging prevention or be bonded in formation stubbornness on fire grate
Property coking, advantageously ensures that the normal use of fire grate, and the service life of fire grate can be improved.
Coking can be not only crushed by fire grate in the course of rotation, but also fuel and coking can be disturbed, favorably
In furnace grate ventilation, keep fuel combustion efficiency more preferable, while being also beneficial to lime-ash whereabouts, using effect is more ideal.
