Hydrogen mixed combustion test device for flexibly modified unit in park

Abstract

The invention belongs to the technical field of combustion tests, and particularly relates to a hydrogen mixed combustion test device for a park flexible transformation unit. In order to overcome the defect that hydrogen mixed combustion engines used for flexibility of an existing park power grid lack related research, the technical scheme adopted by the invention is as follows: the hydrogen mixed combustion test device for the park flexibility transformation unit comprises a combustion assembly, a combustion chamber, a power supply assembly and a power supply assembly, the combustion assembly comprises an end cover and a combustor, and the combustor is provided with a rotational flow section, a combustion chamber and an outlet section; the end cover is connected with the rotational flow section, two sections of combustion parts are arranged in the combustion chamber, and the two sections of combustion parts comprise a front combustion convergence section and a rear combustion diffusion section; the fuel assembly is arranged on the end cover and provides hydrogen / natural gas mixed gas and air for the combustion chamber; the combustion-supporting assembly is used for supplementing air to the combustion chamber; a smoke exhaust assembly; the cooling assembly comprises a water cooling assembly and an air cooling assembly; and a fire-extinguishing assembly. The hydrogen mixed combustion test device has the beneficial effect that a hydrogen mixed combustion test can be carried out.

Description

technical field [0001] The invention belongs to the technical field of combustion tests, and in particular relates to a hydrogen-mixed combustion test device for flexible reformation units in industrial parks. Background technique [0002] The vigorous development of large-scale intermittent renewable energy represented by wind power and photovoltaics has placed great demands on the flexibility of the power grid. There are four main sources of existing flexible resources: flexible operation of dispatchable power plants, energy storage facilities, cross-provincial and cross-regional transactions, and demand-side resources. Compared with the other three types of flexible resources, the flexible operation of dispatchable power plants is currently the most important way to provide flexibility for the power system. [0003] Gas-fired power generation has the advantages of short start-stop time, clean and environmental protection, and plays an important role in power grid peak re...
