Intelligent gas burner ignition system

Abstract

The invention discloses an intelligent gas burner ignition system, and relates to the technical field of burner ignition devices. The intelligent gas burner ignition system comprises a burner ignition part which is skid-mounted in one closed device and a fuel gas conveying part which is skid-mounted in the other closed device. The burner ignition part is provided with an intelligent ignition state tracking subsystem, an incandescent light ignition subsystem, a burner ignition subsystem, a nitrogen purging subsystem, a double-valve leak detection subsystem and a fire extinguishing subsystem. The fuel gas conveying part is provided with the double-valve leak detection subsystem. The fuel gas conveying part is used for conveying fuel gas to the burner ignition part. According to the intelligent burner ignition system disclosed by the invention, the ignition efficiency can be improved, and the safety in the ignition process is improved.

Description

technical field [0001] The invention relates to the technical field of burner ignition devices, in particular to an intelligent gas burner ignition system. Background technique [0002] The key to the successful start of a gas burner is the ignition of the burner. The ignition process of the burner will have a set of strict procedures and specifications. There will be an implosion caused by ignition, causing casualties or safety accidents that damage the equipment of the furnace, and even make the mechanical equipment of the gas furnace damaged or unusable. [0003] The following 8 risk factors lead to safety accidents of gas furnaces [0004] 1. Incomplete purging before starting the gas furnace results in explosive mixtures in the gas furnace combustion chamber after the gas furnace is ignited. [0005] 2. Too little combustion-supporting air leads to incomplete combustion, so that combustible gas will accumulate in the combustion chamber or an explosive mixture will be ...

AI Technical Summary

Problems solved by technology

[0004] 1. Incomplete purging before starting the gas furnace leads to explosive mixture in the gas furnace combustion chamber after the gas furnace is ignited

[0005] 2. Too little combustion-supporting air leads to incomplete combustion, so that combustible gas accumulates in the combustion chamber or forms an explosive mixture after combustion

[0006] 3. The liquid brought out of the fuel gas-liquid separation tank will cause the flame to be unstable when the combustion furnace is ignited, and the liquid in the combustion chamber will cause the liquid in the combustion chamber to implode or burn the equipment over temperature

[0008] 5. Fuel gas enters the furnace area pipe network. Due to the complexity of the pipe network, seal leakage, various valves, flanges, and pipelines are scattered, the leakage of combustible gas generated, entering the furnace and encountering an open flame ignites the furnace area to explode

[0009] 6. Due to the long opening time of the gas shut-off valve, the fuel gas pressure of the igniter, flame sensor, and valve position feedback device does not meet the specified standards, resulting in a mismatch, resulting in ignition failure, or flammable gas release due to prolonged time

[0010] 7. Leakage of the gas valve causes the gas furnace to accumulate combustible gas and cause ignition and implosion

[0012] Due to the current conventional burner ignition operation or the use of PLC program control, none of the above-mentioned 8 risk factors can be overcome, resulting in safety accidents, and even returning to the previous backward manual ignition, resulting in long operation time and high labor intensity. Artificial ignition with naked flames has dangerous consequences for the personal safety of operators
