A water-regulated porous medium pulse isovolumic burner

Abstract

The invention discloses a water temperature adjustment porous medium pulse isometric burner. The burner is characterized by comprising a liquid temperature adjustment porous medium combustion chamber, and two pulse isometric gas burner driving heads arranged on two sides of the liquid temperature adjustment porous medium combustion chamber; and the three are fixedly connected. Compared with the prior art, the burner has the advantages of safety, stability, high efficiency and low nitrogen.

Description

technical field [0001] The invention relates to a porous medium pulse constant volume burner, more specifically, it relates to a water temperature regulating porous medium pulse constant volume burner. Background technique [0002] The combustion methods adopted in existing natural gas burners and burners are isobaric combustion. [0003] Isobaric diffusion combustion has the chronic problem of incomplete and uneven mixing of fuel and air. There is a core with extremely high temperature in the flame envelope, which leads to incomplete combustion and a large amount of NOx. Even if the "high temperature air combustion technology" is used to improve the Combustion efficiency, but as the preheating temperature of the combustion air increases, the formation of high-temperature NOx is also enhanced while the combustion reaction temperature is enhanced. A paradox of high-efficiency combustion and high NOx emissions has been formed. [0004] Isobaric premixed combustion can achiev...

AI Technical Summary

Problems solved by technology

[0004] Isobaric premixed combustion can achieve the purpose of high-efficiency combustion, but it cannot reduce the formation of high-temperature Nox, and there are chronic problems such as small power adjustment ratio and easy tempering

Especially for gaseous fuel systems, the easy tempering characteristic is a safety hazard, which needs to be prevented with various performance and energy consumption costs, but it still cannot be completely eliminated

[0005] The most popular "wire mesh burner" effectively solves the contradiction between high-efficiency combustion and low NOx emissions, but there is no fundamental method to eliminate "premixed combustion and easy tempering"
