Description
Technical field：
The present invention relates to a kind of Coal Conveying System of Power Plant, more particularly to a kind of CFBB large scale to mix burning coal slime
Coal handling system.
Background technology：
Coal in China yield is leapt to the first in the world, and the depth and range of Coal dressing are all answered in fast development, various atures of coal
Miscellaneous changeable, especially coal slime, the yield of coal slime rise year by year, and the comprehensive utilization of coal slime turns into the problem of in the urgent need to address.
Because coal slime is a kind of emission in coal washing process, particle contained therein is very thin (generally all in below 0.5mm), overall
Character is high-moisture (water content is between 25%~40%), high viscosity, high retentiveness, high ash content, simultaneously because coal slime is in coal
Ore deposit coal washery is as discarded object, and the debris in coal slime is more, includes quartz sand, dense medium metal dust.Just because of exist many
Unfavorable conditions, coal slime are difficult to realize large-scale commercial Application, it is very long-term in kept outside of the door by power consumer, with civilian sell and be
Main outlet.Improved with the continuous innovation of technology, domestic all conglomeraties, including coal slime profit is being attempted and explored to power industry all
Maximum gain, therefore, the coal mixing combustion of boiler is into designing institute and an important topic of power plant's research of technique.At present
Domestic many electricity power enterprises all employ various schemes and attempted, and have failure, there is that technology is jejune, also have certainly not
It is successful that burning is mixed in proportion, it should be noted that as long as carrying out coal mixing combustion, more or less all achieves certain economic effect
Benefit.So it suffices to say that coal mixing combustion in the application of Thermal Power Generation Industry is to have very high economic value, plus change give up into
Treasured, beneficial to advantages such as environmental protection, the technique has very far reaching significance.
Coal slime, which mixes burning, at present two kinds of typical techniques, and one kind is that coal slime uses independent pipeline, and that directly enters boiler mixes burning
Method, but very high is required to the impurity of coal slime, it is strict to the moisture control of coal slime, and complexity of conveyance conduit equipment etc.,
Cause cost of investment huge and the operation expense of great number, although 50% or so can be reached at present by mixing burning rate, its is comprehensive
The economic benefit of conjunction is general, and system run all right is bad.Another kind is to mix coal slime in raw coal, by normally giving coal channel
Into boiler, but this scheme is perplexed by viscous bridging, and to result in serious coal breakage not smooth for the burning of mixing of small scale, dredges into
This height, or even by forced-stopping machine, economic loss is serious, although therefore the technique use earliest, come to a halt.With giving coal technology
And there are many targetedly equipment in the development of constantly bringing forth new ideas of auxiliary equipment, market, and it is all to can solve stifled, viscous, knot etc.
More problems, the technical characterstic of these comprehensive equipment, allow coal slime to mix the forward position burnt and shifted technology onto again, as long as thing can be solved smoothly
The problem of material blocks, coal slime mixes burning will be with minimum cost, and stable operating mode is taken the course of its own in industry, then raw coal direct blending combustion
Coal slime (including more combustion of mixed coal) technique will making a breakthrough property progress.Solve the conveying of worst coal slime and what is used ask
Topic, the use for other coals will be even more handy.
The content of the invention：
It is an object of the invention to provide a kind of large scale to mix burn coal slime coal handling system, can realize raw coal and coal slime or its
His coal is uniformly smooth, quantitative in order after mixing to be transported to feeder or boiler, and following for basic condition is provided for coal mixing combustion
