Abstract
The present invention discloses a gasified briquette which is made of 0.5 to 20 % of starch, 5 to 15 % of water, 5 to 15 % of bentonite and rest amount of coal powder, wherein the content of SiO2+Al2O3 in the bentonite is 50 to 70 %, and the content of Fe2O3 is 0.1 to 0.5 %. The present invention has high mechanical strength, the structure is hard to break even at high temperature, and production cost is low.
Description
The present invention relates to a kind of industrial moulded coal.
In the prior art, industrial moulded coal generally adopts pitch to make binding agent, and its hot strength is not high, and binding agent produces environmental pollution; The moulded coal of making binding agent with polyvinyl alcohol is also arranged, its production cost height.The moulded coal of other type exists in various degree also that physical strength is not high, the unfavorable problem of water resistance.
The object of the present invention is to provide a kind of physical strength height, gasified briquette that production cost is low.
Technical solution of the present invention is:
A kind of gasified briquette, its feature: form by following composition by weight:
Starch 0.5～20% water 5～15%
Wilkinite 5～1 5% surplus is a coal dust,
SiO in the wilkinite wherein
2+ Al
2O
3Content be 50～70%, Fe
2O
3Content be 0.1～0.5%.
During making, at first will discharge water in the starch pasting groove, yet be heated to 60～100 ℃ to it with steam or hot water, after dissolving evenly with 40～50 ℃ of left and right sides warm water 0.5～20% living starch again, drop into the gelatinization groove, continue to be heated to 60～100 ℃ to it with steam, stir simultaneously, make colloid, it is 5～15% that above-mentioned water adds total amount, again colloid is mixed, stirs (SiO in the wilkinite wherein with the coal dust of 5～15% wilkinite, surplus
2+ Al
2O
3Content be 50～70%, Fe
2O
3Content be 0.1～0.5%), promptly get the moulded coal of forming by above-mentioned composition by weight with the shaper moulding.Can also carry out drying treatment after making.
Physical strength height of the present invention, even at high temperature structure is also survivable, and production cost is low.
The invention will be further described below in conjunction with embodiment.
