Abstract

The invention discloses a fire coal catalyst. The fire coal catalyst is prepared from, by weight, 4 to 7 parts of calcium hydroxide, 6 to 12 parts of magnesium oxide, 16 to 24 parts of electrolytic aluminium waste residue filtrate, 4 to 7 parts of a nonionic surfactant, 23 to 45 parts of potassium chloride, 8 to 15 parts of dispersing agent NNO, 30 to 40 parts of urotropine, 15 to 25 parts of aerosol, 10 to 20 parts of quick lime, 22 to 34 parts of a sylvite, 12 to 24 parts of atlapulgite, 6 to 10 parts of calcium oxide, 8 to 14 parts of quartz sand, and 2 to 3 parts of rare earth oxide. Beneficial effects are that: no potential safety hazard is caused by the fire coal catalyst; coal combustion characteristics are improved; more complete combustion is realized; excellent economic benefits are achieved; and no influence on the environment is caused.

Description

A kind of coal combustion catalyst

Technical field

The present invention relates to a kind of coal combustion catalyst.

Background technology

China is a big coal country, and being simultaneously also one uses coal big country, and since the establishment of the nation, coal accounts for about 75% in China's primary energy source structure of consumer demand, and expecting the year two thousand fifty this ratio will up to more than 50%.Within longer period, coal will be topmost role in China's energy.Resources for construction saving type, friendly environment society is the long-term task of of China's present stage, and therefore By Reasonable Utilizing Its Coal Resources improves the efficiency of combustion of coal, not only has higher economic benefit, also has great social effect simultaneously.Study efficient burning, low-load combustion-stabilizing, low stain, prevent the combustion system that the problem of slagging scorification and these five aspects of high temperature corrosion is all useful, tool is of great significance.Therefore how improving resource utilization, alleviate environmental pollution, except transforming except combustion unit and processing parameter as possible, also needing more effective coal product.Catalyzer by improving the dynamic characteristic of fired coal combustion, can improve fired coal combustion speed in stove, and make burning more abundant, decreasing pollution, to improve current environment pollution problem.

Summary of the invention

For the deficiencies in the prior art, the problem to be solved in the present invention is, provides a kind of coal combustion catalyst, without any potential safety hazard, improves coal combustion character, makes burning more abundant, brings good economic benefit, and do not affect environment.

For solving prior art problem, technical scheme provided by the invention is, a kind of coal combustion catalyst, and it is made up of the raw material of following parts by weight:

Calcium hydroxide 4-7 part, magnesium oxide 6-12 part, waste slag of electrolytic aluminium filtrate 16-24 part, nonionogenic tenside 4-7 part, Repone K 23-45 part, sodium metnylene bis-naphthalene sulfonate 8-15 part, urotropine 30-40 part, aerosil 15-25 part, unslaked lime 10-20 part, sylvite 22-34 part, atlapulgite 12-24 part, calcium oxide 6-10 part, quartz sand 8-14 part, rare earth oxide 2-3 part.

The invention has the beneficial effects as follows: coal combustion catalyst of the present invention, without any potential safety hazard, improve coal combustion character, make burning more abundant, bring good economic benefit, and environment is not affected.
