Abstract

The invention provides a low-NOx gas burner. The low-NOx gas burner comprises a main pipe body, an inner core pipe and an outer core pipe. Under the condition that the gas inflow amount is constant, afirst position adjusting mechanism is used for changing the gap between the head of the inner core pipe and the main pipe body, in other words, a total outlet of the burner is changed, thus, the flowrate is changed, and the jetting length of jet flames is controlled; under the condition that the flow rate is constant, a second position adjusting mechanism is used for changing the amounts of gasentering the inner core pipe and an inner cavity of the main pipe body separately, and then the positions of hot spots in the jet flames are adjusted; and the jet flames at proper lengths can be rapidly adjusted, lower NOx emission is generated, meanwhile, the positions where the hot spots in the jet flames are released can be conveniently adjusted, and the flame stability and the jet permeabilityare improved.

Description

technical field [0001] The invention relates to a gas burner, in particular to a low NOx gas burner and a flame regulating method thereof. Background technique [0002] In industrial furnaces, especially regenerator glass melting furnaces, the combustion temperature is extremely high, usually in the temperature range of 1300-1650 °C. High furnace and flame temperatures result in high NOx emissions. In order to solve the increasingly stringent emission restrictions, many developed technologies suppress the formation of NOx by modifying the air-fuel ratio, including oxygen-enriched air classification, but such technological transformations require a large investment and high operating costs. [0003] At present, jet flames are also used to produce lower NOx emissions than traditional ones. The burner body is equipped with a manual speed adjustment mechanism. By changing the area of ​​the flame outlet, the flow rate is changed to control the flame length. However, after the f...
