Layered regenerative denitration burner

Abstract

Disclosed is a layered regenerative denitration burner. The layered regenerative denitration burner comprises: a burner body, which includes a gas flow passage, a regenerative chamber and a combustion chamber which are connected in series, wherein the regenerative chamber includes an inner high-temperature regenerative chamber and an outer low-temperature regenerative chamber, the inner high-temperature regenerative chamber communicates with the combustion chamber, the outer low-temperature regenerative chamber encircles at least a part of the outer surface of the inner high-temperature regenerative chamber, partition walls are arranged between the inner high-temperature regenerative chamber and the outer low-temperature regenerative chamber, and the outer low-temperature regenerative chamber comprises a denitration regenerative chamber and a low-temperature regenerative chamber in turn in a direction away from the gas flow passage; a gas flow driving member that is arranged between the inner high-temperature regenerative chamber and the combustion chamber; catalyst inlets disposed on the gas flow passage; openings arranged on the burner body and communicating with the low-temperature regenerative chamber; and gas inlets communicating with the combustion chamber. The usage of the burner can significantly reduce nitrogen oxide emissions in flue gases as well as heat losses.

Description

technical field [0001] The invention belongs to the technical field of gas heat storage and denitrification, in particular, the invention relates to a layered heat storage denitration burner. Background technique [0002] With the rapid development of my country's economy, fossil fuels such as natural gas, oil and coal have been more widely used, making environmental problems increasingly serious, which has caused a series of environmental problems, such as acid rain, ozone layer destruction, greenhouse effect, etc., making us The living environment is becoming more and more severe. my country's coal-based energy structure determines that the emissions of nitrogen oxides and sulfur oxides in our country have always been high. The emission of a large amount of polluting gases has made environmental problems increasingly serious, not only seriously affecting the production and life of our people. , and is not conducive to the sustainable development of my country's economy. Th...

Problems solved by technology

[0004] Regenerative combustion technology, that is, regenerative waste heat recovery technology, the current regenerative waste heat recovery technology, the regenerator is mostly a single straight-through regenerator, and the single regenerator is mostly arranged in a horizontal arrangement, which causes The regenerator occupies a large area, and the high-temperature regenerator is in direct contact with the outside world, resulting in large heat loss

[0005] Therefore, the existing heat storage technology and the problem of nitrogen dioxide pollution in the combustion process need to be solved urgently
