The synergist of the invention can provide sufficient oxygen for the fuel in the combustion process, improve the combustion speed of the fuel, reduce the emission of carbon monoxide and realize the full combustion of the fuel.
The carbon monoxide emission reduction sintering synergist comprises the following raw materials in parts by weight:
preferably, the oxygenation agent is potassium permanganate.
Preferably, the alkali metal salt is sodium chloride or potassium chloride.
Preferably, the alkali metal hydroxide is sodium hydroxide or potassium hydroxide, and the alkaline earth metal oxide is calcium oxide.
Preferably, the desulfurizing agent is ferric oxide.
Preferably, the combustion improver is formed by mixing copper oxide, cerium oxide and aluminum oxide.
Further preferably, the mass ratio of the copper oxide to the cerium oxide to the aluminum oxide in the combustion improver is 1: 1-5: 3.
The invention also provides a use method of the carbon monoxide emission reduction sintering synergist, and specifically the carbon monoxide emission reduction sintering synergist is added into fuel, wherein the addition amount of the carbon monoxide emission reduction sintering synergist accounts for 0.01-0.03% of the mass of the fuel.
Preferably, the fuel includes, but is not limited to, coal.
Compared with the prior art, the invention has the following beneficial effects:
the carbon monoxide emission reduction sintering synergist can provide sufficient oxygen for fuel in the combustion process, and simultaneously reduces dissociation energy of the oxygen and activation energy required by fuel combustion, thereby remarkably reducing the emission of carbon monoxide and improving the combustion efficiency of the fuel. The synergist of the invention improves the RDI +3.15 index of the sinter by about 4-7%, improves the strength of the sinter by about 1-3%, improves the finished product rate of the sinter by about 1-2%, reduces the fuel consumption per ton of ore by about 3-6kg, and can improve the sintering dealkalization metal rate by 10-20%.
