Abstract

The invention discloses a supercritical water gasification and supercritical carbon dioxide Brayton cycle joint production system which comprises a supercritical water gasification coal or biomass or organic waste reaction system and a supercritical carbon dioxide Brayton cycle power generation system. Dioxide carbon generated in a supercritical water gasification system is used for supplementation of dioxide carbon in the Brayton cycle system, the cost is reduced, effective utilization and clean conversion of coal, biomass and organic waste are conducted, waste heat in the supercritical carbon dioxide Brayton cycle power generation system is used for preheating preheated water in the supercritical water gasification system, and therefore the heat efficiency of the system is improved. By means of the supercritical water gasification and supercritical carbon dioxide Brayton cycle joint production system, a new idea is provided for coupling application of the supercritical water gasification system and the supercritical Brayton cycle power generation system.

Description

technical field [0001] The invention belongs to the technical field of clean energy conversion and renewable energy utilization, and relates to a combined production system of supercritical water gasification and supercritical carbon dioxide Brayton cycle. Background technique [0002] With the exponential growth of population, rapid industrialization, urbanization and the improvement of people's living standards, energy, electricity and the environment have become the focus of increasing attention of the international community. In order to solve and deal with energy and electricity shortages and environmental pollution, in recent years, The government continues to increase support for clean energy conversion and renewable energy research. [0003] Coal, biomass and organic waste are abundant resources on the earth, and their effective utilization and clean transformation are very necessary. Thermochemical gasification technology is considered to be the most commercially p...
