Problems solved by technology

[0003] Methanol fuel is a new type of clean fuel that is prepared by using industrial methanol or fuel methanol, adding denatured alcohol additives, and existing national standard gasoline and diesel or component oils according to a certain volume or weight ratio through strict scientific processes. It can replace gasoline and diesel , because it contains oxygen, it can be fully fueled and belongs to clean energy. In addition, methanol has a wide range of sources and can be obtained through various channels. It is a renewable energy source. The use of methanol fuel in boiler combustion has great impact on reducing environmental pollution and creating economic benefits. Great significance and abyssal impact, however, the methanol fuel in the prior art has problems such as low calorific value, incompatibility with the current boiler combustion system, and storage danger, so it cannot be directly applied

Abstract

The invention relates to methanol fuel specially used for boiler combustion. The methanol fuel comprises the following components in percentage by mass: 85% of methane, 1-7% of acetone and 8-14% of a component A, wherein the component A is one or mixture of more than one of zinc peroxide, diethyl ether, dimethyl methane, a fat type active agent, methyl tertiary-butyl ether and normal octane. The methanol fuel provided by the invention has the advantages that caloric value of the methanol fuel can be beneficially improved, a preparation technology is simple, period is short, and technological conditions are controlled, so that non-renewable boiler fuel at present can be conveniently replaced, tail gas discharged through boiler combustion is cleaner, and carbon monoxide in exhaust gas emission is reduced by at least 95%.

Description

technical field [0001] The invention relates to a special methanol fuel for boiler combustion, which belongs to the technical field of new energy. Background technique [0002] Now the main raw material of boiler fuel is diesel. Diesel belongs to fossil energy and is a non-renewable resource. With the development of the economy, the demand for energy is increasing, but the available energy is less and less, and the exhaust gas emission after diesel combustion is huge. , become one of the important reasons of haze weather, more and more uneconomical and applicable. [0003] Methanol fuel is a new type of clean fuel that is prepared by using industrial methanol or fuel methanol, adding denatured alcohol additives, and existing national standard gasoline and diesel or component oils according to a certain volume or weight ratio through strict scientific processes. It can replace gasoline and diesel , because it contains oxygen, it can be fully fueled and belongs to clean energ...
