Problems solved by technology

However, the chemical composition of the process exhaust gas is not fixed, and sometimes the effective combustible components are low. At the same time, the process exhaust gas is also affected by the process and unfavorable factors such as unstable gas source, which brings difficulties to the ignition and stable combustion of the new burner.

Abstract

The invention discloses a double-gas burner, which comprises a shell, a spray head arranged on the top of the shell, a gas pipe extended into the shell from the lower part of the shell, a whirl sheet arranged on the middle part of the shell, and a process waste gas pipe which is communicated with process waste gas and opened vertical to the axis of the shell in the shell, wherein the whirl sheet divides the inner part of the shell into a waste gas chamber on the lower part and a mixing chamber on the upper part; the process waste gas pipe is opened in the waste gas chamber, and the gas pipe upwards extends from the center of the whirl sheet to enter the mixing chamber; and the whirl sheet is provided with an oblique whirl hole for producing whirl gas. By the burner, the fuel is saved, environmental pollution is reduced, waste gas and natural gas are mixed in the shell and then burnt, the burning effect is strengthened, and the flame is rigid and powerful.

Description

technical field [0001] The invention relates to a double gas burner, in particular to a gas burner used in the bottom center of a heating furnace in the petrochemical industry. Background technique [0002] For a long time, burners in the chemical industry usually use single fuel natural gas or liquefied petroleum gas as fuel for combustion. Natural gas and liquefied petroleum gas have the advantages of stable gas sources and high effective combustible components. However, after chemical companies start up and put into production normally, a large amount of process waste gas will be generated. Process waste gas contains effective combustible components (such as: H2, CO, CH4, etc.). However, there will still be a large amount of process waste gas discharged in vain, resulting in waste of resources and environmental pollution. On the one hand, the use of a single fuel such as natural gas or liquefied petroleum gas has the advantages of stable fuel gas source and high effectiv...
