Background

As is well known, the environmental pollution causing human beings to live is mainly carbon dioxide, sulfur dioxide, hydrocarbon, oxynitride, which cause great harm to physical and psychological health of people. According to the statistical data at home and abroad, more than 75% of the environmental pollution in urban areas is caused by insufficient combustion of fossil and biological energy. The environment pollution is caused by the property of the used fuel, most of the fuels at present are solid fossil, biological fuel, liquid gasoline, diesel oil, pipeline gas and the like, the formal chemical names of the main components of the fuels are carbon monoxide, carbon dioxide, alkane of C5 to C12 and alkane of C15 to C18 respectively, the flames are not stable and complete during combustion, and the contents of carbon monoxide, carbon dioxide, sulfur dioxide, hydrocarbon and oxynitride in the discharged waste gas are higher, so that the serious pollution of air is caused.

However, two major hazards which are difficult to solve up to now are brought to human beings; 1. is the emission of carbon dioxide and hydrocarbon. 2. Is the emission of sulfur dioxide and oxynitride. Seriously polluting the living environment on which human beings rely for survival.

In order to solve the two problems noted by the world people, some countries also take corresponding measures to correspondingly reduce the emission, but the two fatal problems are not fundamentally solved so far.

The hydrogen is an energy carrier, people can utilize the energy stored in the hydrogen in a large scale, the hydrogen is used as a secondary energy source, the energy efficiency is high, wastes such as carbon dioxide and sulfur dioxide are not generated, and the hydrogen has the characteristics of cleanness, high efficiency, wide source, renewability and the like. The development of the reasonable application of the hydrogen energy is expected to become an important way for improving the energy efficiency, reducing the pollution emission, reducing the consumption of fossil energy and biological energy, ensuring the energy safety, improving the ecological environment and realizing the diversified development of the energy.

Hydrogen energy is regarded as a final-grade energy of human beings by the present society, and is a very superior new energy, and the reason is as follows: (1) water is inexhaustible as a renewable energy source. (2) The fuel after hydrogen cracking catalytic combustion greatly reduces the emission of pollutant gases.

The main advantages are: the combustion heat value is improved, the pollution emission is reduced, the energy structure is changed, and the fuel consumption is saved. The heat value of fuel after cracking and catalyzing can be increased by 20-35% after each kilogram of fuel is combusted. For internal combustion engines, the thermal efficiency of 17% gasoline can be increased. The composite material is used for heat exchange and flame processing of a kiln, can improve the combustion efficiency by 20-35% and reduce the pollutant emission by more than 85-95%. The classical process of recycling and continuous development of natural substances is demonstrated.

If a hydrogen-oxygen gas and fuel integrated combustion control system can be designed, the use popularity of hydrogen energy can be further improved.
