Coal-based methanol-ether fuel additive based on chemical by-products and application thereof

Abstract

The invention relates to a coal-based methanol-ether fuel additive based on chemical by-products and application thereof. The raw material formula comprises the following components in parts by weight: 50-100 parts of a first alkyl alcohol monoalkyl ether, 50-100 parts of a second alkyl alcohol monoalkyl ether, 60-120 parts of peri-acid, 60-120 parts of Laurent's acid, 5-10 parts of nanocrystalline metal oxides, 1-5 parts of an emulsifier and 500-1000 parts of polyhydric alcohols. With the adoption of a specific formula, particle morphology of pulverized coal can be improved, flowing smoothness of the pulverized coal in a pulverized coal injection process is promoted, and stable pulverized coal combustion is guaranteed, so that the air amount of a primary air fan can be reduced, the cold air entry quantity is reduced, and the aims of saving coal and reducing nitrogen are achieved; and moreover, the fuel additive has the advantage of wide adaptability, can be applied to cement plants, power plants and other industries in which coal serves as main fuel, and is applicable to different coal types such as fault coal, blind coal, bituminous coal and high-sulfur coal.

Description

technical field [0001] The invention belongs to the field of fuel additives, in particular to a coal-based alcohol ether fuel additive based on chemical by-products and its application. Background technique [0002] In 2014, China's total energy consumption was 4.26 billion tons of standard coal, an increase of 2.2% over the previous year. Among them, coal consumption accounts for 66.0% of the total energy consumption. According to the data, coal is still the mainstay of my country's energy. my country has become the world's largest coal producer, but also the world's largest coal consumer. Coal consumption enterprises have become the key industries polluting the environment in our country. At present, most coal-fired enterprises do not add coal-fired additives, and still continue the traditional way of direct combustion. The main disadvantages of direct combustion are: first, insufficient coal combustion, low boiler thermal efficiency, wasting precious coal resources; I...

AI Technical Summary

Problems solved by technology

The main disadvantages of direct combustion are: first, insufficient coal combustion, low boiler thermal efficiency, and waste of precious coal resources; It contains sulfur dioxide and nitrogen oxides, which are discharged into the atmosphere to form acid rain and pollute the environment

[0003] The existing coal-based alcohol ether fuel additives need to import raw materials from abroad during the preparation, resulting in high cost

The chemical by-products such as peri-acid, laurentic acid and polyols have caused damage to the environment of our country: peri-acid and laurentic acid are white needle-like crystals, which are poisonous and are used to make azo dyes. It can cause severe headache, dizziness, dyspnea, cyanosis, hematuria, anuria, mental disorders, muscle convulsions later on; it can be combustible when exposed to open flames and high fever, and can be decomposed by high heat to release toxic gas, which has a great impact on the environment; polyols are a An odorless, colorless, water-soluble and hygroscopic liquid, slightly toxic, flammable in case of open fire or high heat
