Combustion electricity production method implementing staged utilization of flame

Abstract

The invention relates to the technical field of combustion electricity production, and aims at providing a combustion electricity production method implementing staged utilization of flame. The method comprises the steps: 1) setting at least one group of photovoltaic batteries around a combustor in a combustion chamber for a traditional fuel oil or combustion gas boiler, wherein the group of photovoltaic batteries are connected with the matched parts, of the photovoltaic batteries, outside the combustion chamber through wires; a cooler is arranged on the back of the group of photovoltaic batteries; and the group of photovoltaic batteries directly convert the optical energy released from combustion into electric energy, and store the electric energy in a storage battery in the matched parts of the photovoltaic batteries; and 2) adjusting the structure form selection of the cooler, the distance between the combustor and the group of photovoltaic batteries, and the dielectric circulation process parameter to enable the heat exchange amount of the cooler to occupy 10-20% of the total combustion energy in the combustion chamber. The combustion electricity production method implementing staged utilization of flame expresses the idea of cascaded utilization of energy, takes photoelectric conversion of the optical energy which can be directly converted into electricity as the first step for energy conversion, takes recovery of heat energy as the second step for energy conversion, and can avoid waste of the energy quality through reasonable utilization of the energy so that the system heat efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of combustion power generation, and in particular relates to a combustion power generation method for realizing staged utilization of flames. Background technique [0002] Combustion technology is the core technology of modern industry and the main way of consuming fossil energy. At present, the most important application of combustion technology is boiler combustion, and its combustion efficiency can reach more than 95%. However, if it is considered that the main heat is used to generate electricity, the actual efficiency is not high. The thermoelectric conversion efficiency of the most advanced ultra-supercritical combustion technology is only 45%, and this efficiency has reached the bottleneck of the field, and further improvement is difficult and space-consuming. limited. [0003] At present, new chemical energy utilization methods include: fuel cells, chemical chain combustion, thermal photovoltaics, ...
