Gas burning system and igniting method thereof

Abstract

The invention discloses a gas burning system. The gas burning system comprises a burning chamber, a gas main pipeline, a gas branch pipeline, an air main pipeline and a central control unit, wherein the gas main pipeline and the air main pipeline are respectively connected with the burning chamber, the gas main pipeline is sequentially provided with a first gas pressure sensor, a first cutting valve, a second cutting valve and a second gas pressure sensor along the flowing direction of gas, the gas main pipeline between the first cutting valve and the second cutting valve is communicated with one end of the gas branch pipeline, the other end of the gas branch pipeline is connected with the burning chamber, the gas branch pipeline is provided with a third cutting valve and a fourth cutting valve, and an igniting device and a fire detecting device are arranged inside the burning chamber. The burning system ignites in a fire-leading mode and can control the process before and during fire-leading and during working and burning. Accidents caused by the deflagration phenomenon and the gas leakage are prevented.

Description

technical field [0001] The invention relates to a combustion system, in particular to a gas combustion system, and also to an ignition method of the combustion system. Background technique [0002] At present, gas is used as the heat source in the drying process of mineral wool boards, and the blower sends the hot gas generated by the combustion of natural gas burners into the drying area. However, when using medium and large burners, safety accidents are prone to occur during the ignition process. If the natural gas fails to ignite and enters the dry area, it may cause an explosion in the dry area, or if the natural gas is passed too much before ignition, it will cause deflagration in the combustion chamber, damage the equipment, or even cause an explosion, resulting in serious economic losses and casualties, or When the pressure of the gas source is unstable, there are large fluctuations, and when the gas leaks, the fire cannot be extinguished in time, resulting in serious...

[0002] At present, gas is used as the heat source in the drying process of mineral wool boards, and the blower sends the hot gas generated by the combustion of natural gas burners into the drying area. However, when using medium and large burners, safety accidents are prone to occur during the ignition process. If the natural gas fails to ignite and enters the dry area, it may cause an explosion in the dry area, or if the natural gas is excessively introduced before ignition, it will cause deflagration in the combustion chamber, damage the equipment, or even cause an explosion, resulting in serious economic losses and casualties, or When the pressure of the gas source is unstable, there are large fluctuations, and when the gas leaks, the fire cannot be extinguished in time, causing serious safety accidents, etc.
