Embodiment 1

[0013] Embodiment 1: The components of the coal-saving agent are 10% of the catalyst chromium trioxide, 7% of the combustion aid ammonium persulfate, 40% of the penetrant water, 20% of the leavening agent sodium chloride, and 20% of the cleaning agent cyclopentadiene. 6%, dispersant polyoxyethylene ether 7%, sulfur-fixing agent calcium oxide and sodium carbonate mixture 10%, diluted with water, mixed into coal, compared with coal without coal-saving agent, the carbon content of ash slag increased from 17.45 % is reduced to 12.98%, harmful gas is reduced by more than 60%, Ringelmann blackness is less than 1 grade, and coal saving rate is 11.2%.

Embodiment 2

[0014] Example 2: The coal-saving agent components are 7% of the mixture of catalyst titanium trichloride, nickel sulfate, and cerium nitrate, 3% of the combustion aid ammonium persulfate, 40% of the penetrating agent water, and the leavening agent sodium chloride according to the weight percentage. 22% mixture with potassium chloride, 10% detergent cyclopentadiene, 12% dispersant polyoxyethylene ether, 6% sulfur-fixing agent calcium oxide and sodium carbonate, diluted with water, mixed into coal, and without Compared with the coal of the coal-saving agent, the carbon content of the ash is reduced from 12.65% to 9.35%, the harmful gas is reduced by more than 60%, the Ringelmann blackness is less than 1, and the coal-saving rate is 11.9%.

[0015] At the same time, after adding the coal-saving agent, the number of boiler cleaning ash and slag is greatly reduced, and there is no ash and slag coking phenomenon.

Abstract

The invention relates to a coal-saving agent and a preparation process thereof. The coal-saving agent comprises, in weight percent, 6-12% of catalysts, 1-7% of combustion improvers, 25-35% parts of penetrating agents, 25-35% parts of bulking agents, 7-15% of cleaners, 10-20% of dispersing agents and 7-12% of sulfur fixing agents. According to the coal-saving agent, combustion conditions of a furnace body can be improved, coal seam permeability is enhanced, coal is sufficiently combusted, coal burning heat efficiency is improved, soot emission volume is reduced, heat transmission efficiency isimproved, sulfur is fixed, smoke is reduced, emission of CO and SO2 is reduced, environmental pollution is reduced, so that combustion is facilitated, the sulfur is fixed, energy is saved, the sulfuris removed, coal can be saved by 5%-10%,heat power is improved by 10% or more, carbon deposit is removed by 50-90%, and the sulfur is reduced by 20-50%.

Description

technical field [0001] The invention relates to coal energy, in particular to a coal-burning additive, in particular to a coal-saving agent. Background technique [0002] Coal is one of the main energy and chemical raw materials in our country, especially as an energy source, it is the most widely used energy raw material in modern industry. However, as the reserves of coal resources on the earth are getting less and less, the price of coal is getting higher and higher, and the country and relevant departments have stricter and stricter requirements on coal combustion smoke exhaust. How to improve the utilization rate of coal and reduce its pollution has become an important world issue. According to the current research direction, the coal-saving agent can effectively solve these problems, but the existing coal-saving agent is only in its infancy, the effect is not obvious, and there are shortcomings such as large amount of addition, pollution of the environment, and substa...
