Description
Technical Field

Background
The electric power industry in China starts late, and the development way of technology introduction, digestion and absorption, improvement and innovation is developed. In a coal electric structure system in China, the number of 300 MW-grade subcritical units is the largest, wherein the percentage of service life within 20 years reaches 82.8%, and the units of the group can reach the design life in recent years. Compared with developed countries, the power industry starts early, the service time of the unit is long, and the average service time of the coal-electricity unit is more than 24 percent of 30 years in service in the global range. The service life of nearly 50% of coal electric units in Japan is 30-39 years, and the service life of 25% of coal electric units exceeds 40 years. The average life span of a coal-fired power plant in the united states is 42 years, with 11% of the plants operating over 60 years. Therefore, the unit can still run safely and stably for a long time after reaching the design life through the service life prolonging transformation, and brings a great amount of marginal benefits for the society and enterprises.

Hydrogen energy has become one of the important alternatives for future energy sources as a current and popular research direction. The method is a feasible technical route for preparing hydrogen and storing the hydrogen by various methods and converting the hydrogen and the stored hydrogen into high-quality electric energy again.
On one hand, the residual value of the active coal-fired unit is exerted, the waste of resources is avoided, and on the other hand, the large-scale conversion of hydrogen energy is realized. The two problems are coupled to solve, namely most of the equipment of the active coal-fired thermal power generating unit is used, hydrogen fuel power generation is realized, and the requirements of the two aspects can be met simultaneously.
Boiler equipment using hydrogen as fuel for combustion has application cases in the chemical industry, but the boiler equipment is small in scale and simple in system, and mainly exists in the form of recycling waste gas and utilizing residual energy at present. But the large-scale application in the coal-fired thermal power industry is not reported. From the combustion characteristic of hydrogen, the flame propagation speed is high, the combustion intensity is high, and the technical problems of combustion, heat transfer and equipment matching need to be solved for coupling with an active coal-fired thermal power generating unit.
