Abstract

The invention discloses a high-calorific-value clean fuel for industrial boilers, which is prepared from the following raw materials in percentage by weight: 50-80% of methanol fuel, 20-50% of high-calorific-value additive, 1-10% of cosolvent and 0.1-1% of corrosion inhibitor. The high-calorific-value additive consists of the following substances: naphtha, pine tar and diesel oil; the cosolvent isethylene glycol butyl ether; the corrosion inhibitor is composed of sodium benzoate, benzotriazole, pyrazolone and sodium dodecyl sulfate. The method is simple, is convenient in operation and low inraw material cost; in addition, some wastes generated in the chemical production process are treated and converted into high-calorific-value clean fuel, so that the fuel is green and environment-friendly; and in the production, storage and transportation process, flammability and explosiveness are avoided, and safety and reliability are achieved. The biomass fuel can be widely applied to industrial boilers and can also be used as domestic fuel.

Description

technical field [0001] The invention relates to the technical field of clean energy, in particular to a high calorific value clean fuel for industrial boilers and a preparation method thereof. Background technique [0002] my country is a big country that consumes coal. Coal-fired boilers are widely used in early energy consumption, and they should be concentrated in heating, metallurgy, papermaking, building materials, chemical industries, etc., mainly distributed in industrial and populated towns and surrounding areas. Dense areas mainly meet the needs of residents for heating and industrial hot water and steam, and the exhaust gas sulfur dioxide, nitrogen oxides and particulate matter produced by burning coal affect the health of surrounding residents and the atmospheric environment. If these exhaust gases are not used professionally Effective treatment of waste gas treatment equipment will cause serious environmental and ecological problems. However, in the process of pro...
