Abstract
The compound method of a kind of new section coal provided by the invention, it is to mix stirring pressing and moulding according to a certain ratio by pulverized anthracite, black liquid, alditol waste residue, tackiness agent.Characteristics such as the present invention has saving coal, reduces cost, and thermal value is big.
Description
The invention belongs to domestic fuel.
At present, using moulded coal as the civilian energy of cooking, warming oneself, is a kind of heat that can make full use of coal, reduces environmental pollution, convenient civilian comparatively science mode.With the moulded coal manufacture method of living is that coal is pulverized, and adds a certain proportion of mild clay and water, through mechanical compression molding, can use after drying naturally.But coal resources are limited, human to coal demand in continuous increase, its reserves will constantly reduce, and a day of approach exhaustion is arranged at last.
Task of the present invention is at reducing coal consumption, to improve the moulded coal thermal value, the compound method of a kind of new section coal that is provided.
The present invention can prepare (with 100 parts of re-computation) as follows:
40～70 parts of pulverized anthracites
5～40 parts of black liquids
5～40 parts of furfuraldehyde waste slags
10～20 parts in tackiness agent
Mix stirring pressing and moulding with known method.Tackiness agent is to add 0.25～5% magnesium chloride with mild clay to be mixed and made into.
The present invention has following characteristics:
1, saves coal 20～40%, reduce moulded coal cost 15～30%, improve thermal value 200～300 kilocalories (when the pulverized anthracite thermal value is 4000 kilocalories).
2, new section coal is nonhygroscopic, is difficult for brokenly, and modification not substantially after the burning is used convenient transportation.
3, eliminated the pollution of black liquid and furfuraldehyde waste slag for environment.
Embodiment:
Get the pulverized anthracite or the semi-anthracitic coal powder (thermal value is 4000 kilocalories) of 50 parts of weights, the black liquid of 10 parts of weights, the furfuraldehyde waste slag of 25 parts of weights, the tackiness agent of 15 parts of weights, put into agitator and stir, then mixture is put into briquette shaper compression moulding, the taking-up nature dries and gets final product.Its thermal value is per kilogram 4130 kilocalories.
Claims (2)
1, a kind of compound method of new section coal is characterized in that proportioning is (by 100 parts of re-computation):
40～70 parts of pulverized anthracites
5～40 parts of black liquids
5～40 parts of furfuraldehyde waste slags
10～20 parts in tackiness agent
Mix stirring pressing and moulding with known method.
2, the compound method of a kind of new section coal according to claim 1 is characterized in that tackiness agent is to be mixed and made into the magnesium chloride that adds 0.25～5% in the mild clay.
