Problems solved by technology

[0002] Coal is my country's main primary energy source, but coal combustion is insufficient, energy utilization efficiency is low, and it brings serious air pollution
At present, most of the clean utilization of coal is to pulverize coal and add solid concentrate, and then process shaped coal, which not only increases equipment, but also adds solid substances such as clay, lime, etc., which do not burn themselves and absorb heat during combustion , reduces the combustion efficiency of coal, so the effect is not ideal

example 1

[0053]Produce concentrated liquid raw material ratio of the present invention: potassium permanganate 10kg, potassium perchlorate 50kg, sodium nitrate 50kg, potassium dichromate 10kg, boron oxide 20kg, borax 10kg, sodium chloride 100kg, rare earth chloride 10kg, water 740kg, put Put into a shearing machine with a rotating speed of 1800 rpm, and stir; then 15kg of calcium carbonate, 5kg of calcium oxide, and 5kg of magnesium carbonate are respectively pulverized into powders with a particle size of less than 1mm, mixed, and 75kg of water is added, stirred evenly, and then mixed with the above Agents were mixed and stirred for 1 hour to obtain the concentrated solution of the present invention. When spraying on coal, take 5kg of energy-saving, sulfur-reducing and dust-removing concentrate and dilute it with 200kg of water, spray it on 5000kg of coal, and test it on a 10T / hour chain boiler. The temperature of the furnace is increased by 121°C, which can reduce the smoke and dust b...

Abstract

The invention discloses an energy-saving, eliminating sulfur and falling dust concentrated liquid, which comprises the following steps: choosing kalii permangana, thyronorman, sodium nitrate, common salt, rare earth chloride, calcium carbonate, calcia, magnesium carbonate, potassium bichromate, boric oxide and borax as raw material; grinding calcium carbonate, magnesium carbonate and calcia to powder with grain size smaller than 1mm; mixing the raw material; adding into water; stirring evenly; getting the product. This concentrated liquid can be mixed into coal, which can increase the temperature of fire box and the heating efficiency of high boiler.

Description

technical field [0001] The invention belongs to a coal-burning additive concentrated liquid capable of fully burning coal and reducing pollutant discharge, in particular to an energy-saving, sulfur-reducing, dust-removing concentrated liquid. Background technique [0002] Coal is the main primary energy source in our country, but the combustion of coal is not sufficient, the efficiency of energy utilization is low, and it brings serious air pollution. At present, most of the clean utilization of coal is to pulverize coal and add solid concentrate, and then process shaped coal, which not only increases equipment, but also adds solid substances such as clay, lime, etc., which do not burn themselves and absorb heat during combustion , reduce the combustion efficiency of coal, so the effect is not ideal. Contents of the invention [0003] The object of the present invention is to provide an energy-saving, sulfur-reducing and dust-removing concentrated solution, which can be m...
