Description
Technical field
It is specifically a kind of to be suitable for more biomass fuels, Anti-slagging, knot the utility model relates to a kind of biomass combustion machine
Burnt biomass rotary fire grate combustor.
Background technique
Biomass fuel is a kind of using agricultural waste as raw material, by techniques such as crushing, mixing, extruding, drying,
A kind of various Novel clean-fuels that forms (such as blocky, graininess), can directly burn are made.
Existing biomass fuel is many kinds of, fuel have moisture high (generally 45% or more), impurity it is more (mixed with
Soil, fine sand), the features such as ash is high, alkali metal content is high, the fuel of current combustion machine is mainly biological particles, can not be compared with
It is good to be suitable for biomass block, chip, the fuel such as rice husk, corncob, when this fuel is deposited directly in burner hearth, due to furnace
Thorax unreasonable structure, can be low after the ash softening of high-temperature region if heat distribution is irregular in burner hearth after burner hearth fuel combustion
Warm area coking.After pot slagging, the efficiency of combustion of normal fuel can be reduced, blocks burner hearth, changes the heat distribution in burner hearth,
It is further exacerbated by coking to become formula, reduces the vapor (steam) temperature of boiler, exhaust gas temperature rises, and generates the nuisances such as large quantity of exhaust gas dense smoke
Matter, so aggravate slagging, coking and increase detonation a possibility that so that burning after biomass ash can not easily, quickly, even
Continuous cleaning causes combustor that can not continue working, and then the requirement normally produced is not achieved.
The slagging of biomass combustion machine processing at present, there are mainly two types of methods for coking: a kind of to use steam sootblower to heated
Face carries out the processing of coking deashing, because the Determination of Potassium in biomass fuel is higher, the dust stratification adhesive force containing potassium is very strong, is difficult
Product coke button is handled into the method completely also having using decoking inhibitor, it is another in fuel after addition inhibitor, life to be increased
Cost is produced, nor is conducive to environmental protection, has violated the original intention using biomass fuel.Although above two method is to a certain degree
On alleviate slagging and coking phenomenon, but solve incomplete combustion there is no basic, burning cost is big, and since burning is not filled
The problem of noxious material caused by point and flue gas emission, pollution environment.
There are mainly two types of methods for biomass combustion machine processing biomass ash at present: it is a kind of to use artificial scarfing cinder ash removal method,
By manually carrying out scarfing cinder deashing with scarfing cinder ash cleaning tool for heat, but artificial scarfing cinder deashing is not thorough in the presence of cleaning, and low efficiency, danger is made
The problems such as industry, the external slag-removing ash-cleaning machine that another kind uses carry out the operation of scarfing cinder deashing, but external slag-removing ash-cleaning machine need with
Combustor connects external conveyance conduit, time-consuming, arduously, and has scarfing cinder deashing to be not thorough, cannot operation simultaneously, efficiency is slow etc. to ask
Topic.
