Problems solved by technology

[0003] At present, the commonly used regenerative combustion technologies include regenerative oxygen-enriched combustion technology and purified regenerative combustion technology. Among them, regenerative oxygen-enriched combustion technologies are mostly simply mixed with oxygen on the basis of regenerative combustion, so that To increase the oxygen concentration, this method often needs to purchase or manufacture oxygen separately, and there are problems of oxygen transportation and cost, especially the continuous operation requires a large amount of stable oxygen source, which is difficult to realize; the purification regenerative combustion technology refers to the regenerative combustion technology used The material of the regenerator is replaced with one that can catalyze the combustion reaction, so that the combustion is as complete as possible, and the generation of carbon ash and carbon monoxide is reduced. This technology is limited to the material of the regenerator, and it has not realized the accumulation of carbon dioxide, and cannot achieve carbon neutrality.
