Embodiment 1

[0010] Example 1, the additives of the present invention include exothermic agents, oxidants and gas conversion agents, and other auxiliary materials such as isooctyl alcohol can also be added. The exothermic agent can be charcoal powder, graphite, or higher-purity pulverized coal, or other powder with higher coal combustion value, or a mixture of the above-mentioned substances in any proportion, and the oxidizing agent can be industrial salt, calcium oxide, or di Iron, etc., or a mixture thereof, and the gas conversion agent may be potassium permanganate powder, manganese sand, or manganese naphthenate, etc., or a mixture thereof. The weight ratio of the exothermic agent, the oxidant and the gas conversion agent is: 60-90 parts of the exothermic agent, 10-25 parts of the oxidant, and 10-25 parts of the gas conversion agent; the preferred weight ratio of the additive is: 65-80 parts of the exothermic agent 12-20 parts of oxidant, 12-20 parts of gas conversion agent; the optima...

Embodiment 2

[0011] Embodiment 2, first prepare mixed coal combustion, described mixed coal combustion comprises raw coal and carbonaceous waste, described carbonaceous waste comprises fly ash, peat, cinder, and the calorific value of described carbonaceous waste should be greater than 200 kcal, preferably between 200-1000 kcal, the ratio of raw coal and carbon-containing waste is 100: (30-50) by volume, and 2-5% of the mixed coal weight is added to the mixed coal Stir the water evenly; then, add the above-mentioned additives in the mixed coal and stir evenly, the weight ratio of the additives added in the mixed coal is (120-180): 1, the preferred weight ratio is (130-170): 1, Preferably 150:1. When the prepared coal is added to the boiler for use, the flame condition of the furnace is obviously improved, the flame is high, and the fire is vigorous. At the same time, there is no coking phenomenon on both sides of the furnace, the fly ash and sulfur dioxide are greatly reduced, and the blac...

Embodiment 3

[0014] Embodiment 3, the present invention can also first add the additive described in claim 1 in the carbon-containing waste, fly ash, peat, or cinder, or any mixture of two kinds, or the mixture of the above three kinds, and stir evenly, Add raw coal and water and stir evenly, wherein the raw coal and carbon-containing waste are proportioned by volume 100: (30-50), the amount of water added is 2-5% of the total weight of raw coal and carbon-containing waste, and the amount of additives added The ratio of the weight to the total weight of raw coal and carbon-containing waste is 1: (120-180). All the other are with embodiment 2.

Abstract

The invention discloses an environment-friendly energy-saving additive for coal and an application method for the environment-friendly energy-saving additive. The invention mainly solves the technical problems that carbon-containing waste such as coal slag and the like is hardly reutilized fully and the like in the conventional coal combustion method. The technical scheme has key points that: the additive comprises the following components in part by weight: 60 to 90 parts of heat generating agent, 10 to 25 parts of oxidant and 10 to 25 parts of gas converting agent, wherein the heat generating agent comprises charcoal dust and graphite; the oxidant comprises industrial salt and calcium oxide; and the gas converting agent comprises potassium permanganate powder or industrial alkali. The application method comprises the following steps of: adding the additive into flyash, peat, or coal slag, or a mixture of any two of the flyash, peat and coal slag, or a mixture of the flyash, peat and coal slag in the carbon-containing waste, uniformly stirring, mixing with raw coal and water, and uniformly stirring, wherein the raw coal and the carbon-containing waste are mixed in a volume ratio of 100:(30-50); the water adding amount is 2 to 5 percent based on the total weight of the raw coal and the carbon-containing waste; and a weight ratio of the additive to the sum of the raw coal and the carbon-containing waste is 1:(120-180). The additive is easy and convenient to use, can effectively reduce the coal combustion cost of users, can be widely applied to boilers or kilns of medium-sized and small enterprises, and is particularly suitable for a concentrated coal distribution center.
