Technical Field

The invention relates to the technical field of clean energy, in particular to a high-calorific-value clean fuel for an industrial boiler and a preparation method thereof.

Background

China is a large country consuming coal, coal-fired boilers are commonly used in early energy consumption, and the coal-fired boilers are mainly distributed in industries such as heat supply, metallurgy, papermaking, building materials, chemical engineering and the like, mainly in cities and towns with concentrated industry and in surrounding densely populated areas, so that the requirements of residents on heating and industrial hot water and steam are mainly met, the sulfur dioxide, nitrogen oxide and particulate matters in waste gas generated by burning coal influence the health and atmospheric environment of surrounding residents, and the waste gas can generate serious environmental and ecological problems if professional waste gas treatment equipment is not used for effective treatment. However, in the process of controlling the propulsion of coal-related measures, the following problems are generally faced: the natural gas and the electricity are used for replacing coal, and the problems of equipment updating, use cost, stable supply of alternative energy and the like are involved; the promotion of clean coal and the enhancement of clean utilization of coal are difficult to obviously solve the inherent emission problem of coal, and a practical solution is urgently needed to be explored so as to accelerate the implementation of measures and improve the treatment effect. In order to solve the energy problem, people are searching and developing new energy. Among them, methanol has been increasingly used as an industrial boiler fuel. However, methanol has low heat value and low combustion temperature, and the application range of the methanol is severely limited. Therefore, a high-calorific-value clean fuel for an industrial boiler and a preparation method thereof are urgently needed, so that the problem of serious emission of sulfur dioxide, nitrogen oxide and granular atmospheric pollutants caused by combustion of the conventional boiler fuel can be effectively solved, the calorific value of the methanol fuel can be improved, and the application range of the methanol fuel is wider and the methanol fuel is economical.
