New energy and coal-fired power plant coupled low-carbon power generation system using green ammonia as carrier

Abstract

The invention relates to a new energy and coal-fired power plant coupled low-carbon power generation system using green ammonia as a carrier, which belongs to the field of new energy power consumption and coal-fired power plant carbon reduction, and comprises an energy power generation device, an electrolytic hydrogen production tank, an air separation device, an ammonia synthesis tower, an ammonia supply system, an ammonia burner and a pulverized coal boiler, the output end of the energy power generation device is connected with power interfaces of the electrolytic hydrogen production tank and the air separation device, a hydrogen outlet of the electrolytic hydrogen production tank is communicated with a hydrogen inlet of the ammonia synthesis tower, and a nitrogen outlet of the air separation device is communicated with a nitrogen inlet of the ammonia synthesis tower. An ammonia burner is arranged on the wall face of a hearth of the pulverized coal boiler, green ammonia synthesized by the ammonia synthesis tower is conveyed to the ammonia burner through an ammonia supply system and finally sprayed into the pulverized coal boiler to be burnt, and part of fire coal is replaced. Green hydrogen and green nitrogen are prepared by using new energy electric power, then green ammonia which is more convenient to convey and store is synthesized, and finally the green ammonia is outwards conveyed as an energy carrier, so that the problem of new energy grid-connected conveying is effectively relieved.

Description

technical field [0001] The invention belongs to the fields of new energy power consumption and carbon reduction of coal-fired power stations, and specifically relates to a low-carbon power generation system that uses green ammonia as a carrier to couple new energy and coal-fired power stations. Background technique [0002] Under the background of carbon peaking and carbon neutrality, my country's new power system with new energy as the main body is accelerating the construction. However, behind the rapid increase in the installed capacity of new energy power generation, the problem of consumption has gradually become prominent. Due to the randomness, volatility and intermittency of new energy power generation, and the areas rich in wind and solar resources are far from the load center, higher requirements are placed on the flexibility and controllability of the power grid and the ability of external transmission and mutual assistance. The integration of new energy power gen...
