PROCESS AND EQUIPMENT OF FOSSIL FUEL POWER GENERATION WITH ZERO CARBON EMISSION

摘要

A electricity generation method and device using combustion of fossil fuels and having zero-carbon emission provide a complete technical solution of carbon capture and storage (CCS): electricity is generated by carrying out oxygen-enriched combustion of coal and other fossil fuels in an electricity plant at a carbon dioxide sequestration location, and the produced carbon dioxide is introduced, in an onsite manner, into a saline aquifer at the carbon dioxide sequestration location, and the generated electricity is outputted outside. By means of the method, the whole transportation process comprising loading, long-distance transportation and unloading of coal is omitted, so that the difficulty and cost for implementing the complete CCS technical solution are greatly reduced, the feasibility of the CCS technical solution is improved, the implementation of the large-scale carbon capture and storage during electricity generation based on combustion of coal and other fossil fuels is facilitated, electricity is generated by means of combustion of the fossil fuels while zero-carbon emission is achieved, a technical path is added for breaking through difficulties in CCS, so as to finally implement large-scale comprehensive utilization of a great quantity of coal, oil, gas and other fossil fuels and a large quantity of saline aquifer geological resources.
