Embodiment (2

[0020] Embodiment (2): cellulose 3%, potassium chloride 5%, sodium nitrite 3%, bentonite 79% sulfuric acid slag 10%. The above materials are mixed and ground for at least 24 hours. Fine to no particles. White coal is mixed with binder 100:3-5% for later use. After burning for 1 hour, rake out and observe, and it will be found that the coal mixed with the binder is completely burned. Embodiment (3): Maltodextrin 5%, Potassium Chloride 15%, Potassium Permanganate 3%, Ammonium Nitrate 3%, Sodium Nitrite 1%, Bentonite 73%, the above several kinds of materials are mixed and finely ground without any particles , at least stacked for more than 24 hours. White coal is mixed with binder 100:5% for use, and the effect of bituminous coal is better. Put it into the furnace and burn it for 1 hour and then rake it out for observation. It will be found that the white coal mixed with bonding is completely burned.

Embodiment

[0021] Embodiment (4): Cellulose 5%, Potassium Permanganate 10%, Repone K 5%, Ammonium Nitrate 3%, Sodium Nitrite 3%, Bentonite 74%, above several kinds of materials are mixed and ground to disappear particle, Stack for at least 24 hours. White coal is mixed with binder 100:5% for use, and bituminous coal is more effective. Put it into the furnace and burn it for 1 hour and then rake it out for observation. It is found that the white coal mixed with binder burns more completely.

[0022] Embodiment (5): maltodextrin 5%, potassium permanganate 3%, potassium chloride 3%, potassium nitrate 10%, ammonium nitrate 3%, sodium nitrite 3%, sulfuric acid slag 73%, the above several materials After mixing, grind until there are no particles, and stack it for at least 24 hours. White coal is mixed with 100:5% of the binder for later use. If it is bituminous coal, the effect is better. Put it in the furnace and burn it for 1 hour and then rake it out for observation. It is found that afte...

Abstract

The invention discloses a preparation method of a fire coal type boiler for fire coal increasing effect and bonding of crushed coal, belongs to the technical field of organic or inorganic synthesis, and in particular relates to a method using sulphur as an initiating agent and potassium carbonate, potassium nitrate, sodium nitrite, potassium permanganate, cellulose and maltodextrin as a combustion-supporting adhesive.

Description

technical field [0001] The invention is a preparation method for coal combustion or boiler coal combustion enhancement effect and crushed coal bonding. It belongs to the technical field of organic or inorganic synthesis. Specifically, it is a method of using its own carbon and its own sulfur as initiators, adding potassium carbonate, potassium nitrate, potassium permanganate, and adhesives as combustion-supporting adhesives. Background technique [0002] Currently burning coal or fuel oil has become the largest strategic substance in modern times, or called the blood of industry. Modern ironmaking and steelmaking and thermal power plants are the most important industrial raw materials that are indispensable. [0003] In the cement industry in the 1990s, there were high-efficiency coal-saving and rapid raw material firing in shaft kilns. In addition, the thermal power industry uses the grinding method, and the fluidized bed furnace grinds the coal very finely, and then spr...
