Description

Technical Field

[0001] The invention belongs to the technical field of combustion devices, and in particular relates to a burner. Background Art

[0002] As we all know, the environmental pollution that humans rely on for survival is mainly carbon dioxide, sulfur dioxide, hydrocarbons, nitrogen oxides, which have caused great harm to people's physical and mental health. According to domestic and foreign statistics, more than 75% of environmental pollution in urban areas comes from the incomplete combustion of fossil and bioenergy. The generation of environmental pollution depends on the nature of the fuel used. At present, most fuels are solid fossils, biofuels and liquid gasoline, diesel, pipeline gas, etc. The official scientific names of their main components are carbon monoxide, carbon dioxide, C5-C12 alkanes and C15-C18 alkanes. When they burn, the flames are not stable and thorough enough. The exhaust gas contains high levels of carbon monoxide, carbon dioxide, sulfur dioxide, hydrocarbons, and nitrogen oxides, causing serious air pollution.

[0003] However, it has brought two major hazards to mankind that are still difficult to resolve: one is the emission of carbon dioxide and hydrocarbons. The other is the emission of sulfur dioxide and nitrogen oxides. It has seriously polluted the living environment on which humans depend for survival;

[0004] In response to the above two major problems that have attracted worldwide attention, some countries have also taken corresponding measures to reduce emissions accordingly. However, these two fatal problems have not been fundamentally solved so far.

[0005] Hydrogen is an energy carrier. People can use the energy stored in hydrogen on a large scale. Hydrogen, as a secondary energy source, is not only highly energy efficient, but also does not produce waste such as carbon dioxide and sulfur dioxide. It is clean, efficient, widely available, and renewable. The development of hydrogen energy and its rational application is expected to become an important way to improve energy efficiency, reduce pollution emissions, reduce the consumption of fossil energy and bioenergy, ensure energy security, improve the ecological environment, and achieve energy diversification.

[0006] Hydrogen energy is regarded as the ultimate energy source for mankind in today's society. It is an extremely superior new energy source. The reasons are: ① Water is inexhaustible as a renewable energy source. ② The fuel after hydrogen cracking and catalytic combustion greatly reduces the emission of polluting gases. The main advantages are: increasing the calorific value of combustion, reducing pollution emissions, changing the energy structure, and saving fuel consumption. The calorific value of each kilogram of fuel after cracking and catalytic combustion can be increased by 20-35%. When used in internal combustion engines, it can increase the thermal efficiency of gasoline by 17%. It is a classic process of recycling and sustainable development of natural materials.
