Ultralow-nitrogen split type combustor and combustion boiler

Abstract

The invention discloses an ultralow-nitrogen split type combustor. The ultralow-nitrogen split type combustor comprises a machine body. The machine body comprises an outer shell, a rear cover, a burning head, an igniter and an electronic control valve. The igniter and the electronic control valve are fixed to the interior of the outer shell. The rear cover is fixed to one end of the outer shell. Agas inlet is formed in the rear cover. The burning head comprises a first air duct, a second air duct, gas ejection pipes, a flame stabilizing disk, a high-temperature flue gas adjusting ring and ejectors. The flame stabilizing disk is arranged at the end of the first air duct. The high-temperature flue gas adjusting ring is slidably connected to the end of the second air duct. The ejectors are fixed to the ring end of the high-temperature flue gas adjusting ring. The ejectors and the gas ejection pipes are arranged oppositely. The ultralow-nitrogen split type combustor further comprises an air inlet part, a driving part, a control part and a power supply part. Through linkage cooperation between the machine body, the air inlet part, the driving part, the control part and the power supplypart, the ultralow-nitrogen split type combustor can realize fuel grading, combustion-supporting air grading and concentration grading, improves the combustion efficiency and reduces generation of NOx.

Description

technical field [0001] The invention relates to the technical field of burners, in particular to an ultra-low nitrogen split burner and a combustion boiler. Background technique [0002] In recent years, with the rapid development of my country's economy, the problems of environmental degradation and resource depletion have been increasingly exposed. Therefore, the efficient use of energy and the discharge of pollutants have become more serious problems at present. In the current field of boiler burners, NOx is the main pollutant emitted during boiler combustion, which is very harmful to human health and the ecological environment, so it is of great significance to the low-nitrogen transformation of boiler burners. [0003] Due to its unreasonable structure, the burner in the prior art can easily lead to unstable mixing of gas flow and air flow during the combustion process, resulting in unstable combustion, which not only brings great safety hazards in the production proces...
