Metal fuel-based zero-carbon emission energy conversion system

Abstract

The invention discloses a metal fuel-based zero-carbon emission energy conversion system. The metal fuel-based zero-carbon emission energy conversion system comprises a metal particle supply device, agas source, a metal combustion system, a metal electrolytic reduction system and a heat engine, and is characterized in that the metal particle supply device is used for conveying metal fuel particles to the metal combustion system to be combusted with an oxidant conveyed by the gas source to generate oxidation reaction, heat generated by the oxidation reaction is converted into secondary energythrough the heat engine, solid metal oxide generated in the oxidation reaction is conveyed to the metal electrolytic reduction system to be subjected to the reduction reaction, and metal generated after the reduction reaction is treated into metal fuel particles and then conveyed to the metal combustion system again through the metal particle supply device, so that recycling of the metal fuel is realized. Compared with traditional thermal power generation, the metal fuel does not generate any toxic substance or greenhouse gas during combustion, and according to experimental measurement, the carbon emission level is 7 g / kW.h and is only 0.67% of that of coal-fired power generation. The purposes of zero carbon emission and stable combustion power supply are achieved.

Description

technical field [0001] The invention belongs to the field of metal fuel and renewable energy, in particular to a zero-carbon emission energy conversion system based on metal fuel. Background technique [0002] At present, fossil fuels account for more than 80% of the world's energy consumption, but there is a potential energy crisis and it is easy to cause regional turmoil. What is even more difficult is that the mining, transportation and burning of fossil fuels will cause great damage to the environment, especially the burning of hydrocarbon fuels will emit greenhouse gases, leading to global climate change and causing serious ecological problems. Therefore, the search for environmentally friendly renewable energy has always been a focus of attention of the international community. In the 21st century, the application of renewable energy has developed rapidly, and its power generation has accounted for more than 20% of the world's total power generation. However, renewabl...

Problems solved by technology

In the 21st century, the application of renewable energy has developed rapidly, and its power generation has accounted for more than 20% of the world's total power generation. However, renewable energy represented by hydropower, wind power and solar energy has obvious volatility and randomness. And the uneven geographical distribution, if applied on a large scale, may have an adverse impact on the stability of the entire power grid, which has become one of the key factors restricting the further development of renewable energy
