Low-nitrogen double-heat-storage natural gas burner

Abstract

The invention provides a low-nitrogen double-heat-storage natural gas burner, and relates to the field of industrial heating furnace burners. The low-nitrogen-based double-heat-storage natural gas burner comprises a furnace body, wherein the interior of the furnace body is divided into a hearth area B and a hearth area A, two high-temperature heat storage chambers are symmetrically arranged at the top of the furnace body and communicated with the hearth area B and the hearth area A correspondingly, and medium-temperature heat storage chambers are fixedly connected to the tops of the two high-temperature heat storage chambers correspondingly. According to the low-nitrogen double-heat-storage natural gas burner, the heating technology is further optimized, the gap between energy conservation, emission reduction and the like and the international advanced level is reduced, and the development of a heating furnace has a sustainable development road with high technological content, good economic benefit, low energy consumption and less environmental pollution.

Description

technical field [0001] The invention relates to the technical field of industrial heating furnace burners, in particular to a low nitrogen double heat storage natural gas burner. Background technique [0002] At present, the regenerative natural gas burners used in China are generally combustion-supporting air single regenerative energy-saving burners. According to energy saving and emission reduction, regenerative natural gas burners can be divided into single regenerative energy-saving burners, double regenerative energy-saving burners, single regenerative energy-saving low-nitrogen burners, and double regenerative energy-saving low-nitrogen burners. [0003] The low-nitrogen dual regenerative natural gas burner adopts an organic combination of regenerative combustion energy-saving technology and low-nitrogen combustion emission reduction technology. It is mainly composed of a high-temperature regenerator, a medium-temperature regenerator, a layered multi-fire port struct...

AI Technical Summary

Problems solved by technology

Since the single regenerative energy-saving burner only pre-storages energy-saving combustion for the combustion-supporting air, and does not adopt low-nitrogen emission reduction combustion and natural gas pre-storage and energy-saving combustion, the sensible heat of the high-temperature flue gas, which accounts for a large proportion, cannot be obtained. Effective recovery and utilization, high NOx emissions; in terms of thermal automatic control technology, there is generally a single firepower adjustment, and the temperature adjustment in the heat preservation stage can only be realized by turning on and off the gas. Big waste of gas

When the heating furnace, especially the intermittent heating furnace, is shut down, the air enters the high-temperature furnace through the combustion-supporting air blower pipe, and then is discharged through the smoke exhaust fan pipe, so that a part of the sensible heat of the high-temperature furnace is released from the furnace and enters the atmosphere through the air carrier, causing a large number of physical heat loss
