Industry fire coal additive agent

Abstract

The invention discloses a novel industrial coal additive prepared from solid ketene dimmer residue and auxiliary materials. The additive comprises the following components by weight percentage: 70wt%-90wt% of solid ketene dimmer residue, 2wt%-10wt% of quicklime, 3wt%-10wt% of potassium permanganate and 5wt%-10wt% of kaolin. The additive has the advantages that (1) the heating value of the additive per se is not lower than 4,000KCaL / Kg, and the coal can be saved by adopting the additive itself; (2) the additive allows the fuel to burn more sufficiently and even completely, reduces carbon monoxide in the fume, and controls the discharge of the black smoke, thus achieving the coal-saving effect; (3) the additive allows the ash fusion point of the clinker to increase, so as to ensure that the cinder turns to be crisp without generating coke residue, and the additive also reduces the carbon content of the cinder, thus achieving the coal-saving effect; and (4) the raw material of the additive is derived from the industrial waste so as to solve the industrial pollution problem during the process of producing diketene, and the additive is applicable to various industrial boilers based on various coals.

Description

technical field [0001] The invention relates to a novel industrial coal-burning additive prepared from solid diketene residue and auxiliary materials. Background technique [0002] At present, there are many types of coal-fired additives on the market, and their mechanisms of action are different, but in the end they all achieve the purpose of energy saving by improving the utilization efficiency of coal; these coal-fired additives have the following disadvantages: 1. High cost and high price. The synthesis of additives requires a variety of chemical raw materials, and various raw materials must undergo certain chemical reactions before they can be synthesized. 2. The additive itself cannot be burned, nor can it provide heat. Most of the additives are inorganic salts, which cannot be burned by themselves, but only participate in the catalytic reaction, and some also absorb additional heat. 3. The raw material of the additive comes from the common raw material market, and so...

[0002] At present, there are many types of coal-fired additives on the market, and their mechanisms of action are different, but in the end they all achieve the purpose of energy saving by improving the utilization efficiency of coal; these coal-fired additives have the following disadvantages: 1. High cost and high price. The synthesis of additives requires a variety of chemical raw materials, and various raw materials must undergo certain chemical reactions before they can be synthesized

2. The additive itself cannot be burned, nor can it provide heat. Most of the additives are inorganic salts, which cannot be burned by themselves, but only participate in the catalytic reaction, and some also need to absorb additional heat.

3. The raw material of the additive comes from the common raw material market, and some industrial waste or industrial waste cannot be used

4. Coal-saving efficiency is not high

[0003] The thermal cracking method of acetic acid is currently the main method for producing diketene, and the rectification and purification of crude diketene is an essential process. During the rectification process, about 10% of the residue is produced, which is the rectification residue. The residue has a high viscosity and is irritating. Odor, most diketene manufacturers currently use landfill or incineration methods to deal with, these two methods have caused great pollution to the environment
