Abstract

The invention discloses an oxygen-enriched combustion supercritical carbon dioxide cyclone furnace. The cyclone furnace comprises a cyclone furnace body and a tail flue gas comprehensive treatment system. The cyclone furnace body comprises a cyclone tube and a supercritical carbon dioxide boiler. The tail flue gas comprehensive treatment system comprises an SCR denitration device, a dust collector, a gas-gas heat exchanger, a condenser, a first-stage compressor, an air separation device, a cooler, a second-stage compressor, a flue gas mixing device and a pulverizing system. The oxygen-enriched combustion supercritical carbon dioxide cyclone furnace integrates the oxygen-enriched combustion technology and supercritical carbon dioxide power cycle generation organically.

Description

technical field [0001] The invention belongs to the field of advanced and high-efficiency thermal power generation, and relates to an oxygen-enriched combustion supercritical carbon dioxide cyclone furnace. Background technique [0002] In recent years, the issue of the greenhouse effect has become the focus of global attention. CO emissions from fossil fuel energy conversion 2 It is the main reason for exacerbating the greenhouse effect. In my country, coal-fired thermal power generation is the 2 Research and development of new coal-based fuel power generation technology is of great significance to the clean and efficient use of coal resources in my country and the mitigation of the greenhouse effect. [0003] The biggest advantage of oxyfuel combustion technology is that it can directly capture CO in flue gas. 2 It is compressed and liquefied for storage or other uses, and has CO 2 Low recycling cost, NO x Low emissions and other advantages, it is considered to be th...
