Abstract

The invention provides a flameout detection protection and re-ignition device for a heating furnace, and relates to the technical field of heating equipment. The technical problems that no detection means is used for fire extinguishing of the heating furnace, manual discovery is required and hidden dangers exist are solved. The flameout detection protection and re-ignition device for the heating furnace comprises a furnace body, a ventilation door and a chimney are arranged on the furnace body, and the flameout detection protection and re-ignition device further comprises a fire nozzle, a gassupply assembly and two fire extinguishing monitoring assemblies, wherein the fire extinguishing monitoring assemblies are installed in a premixing area and a flame area respectively; the device further comprises a sleeve type tee joint, a switching air valve and a high-pressure fan; a combustible gas sensor is arranged in the chimney; the self-pressurization high-energy high-frequency igniter isarranged in the furnace body and is close to the fire nozzle; and a flame stabilizer is arranged in the air inducing area. The flameout detection protection and re-ignition device disclosed by the invention has the characteristics of safety and capability of monitoring whether fire is extinguished in the heating furnace in real time and closing fuel gas in time or not.

Description

technical field [0001] The invention relates to the technical field of heating equipment, in particular to a flameout detection protection and re-ignition device for a heating furnace. Background technique [0002] Oilfield heating furnace is the key equipment for temperature rise and viscosity reduction in the process of gathering and transportation. Most of the well station heating furnaces use oilfield associated gas (casing gas) as fuel and adopt natural ventilation mode for combustion. Such as figure 1 As shown, a natural ventilation heating furnace currently used in the oil field adjusts or closes the casing gas through the manual valve group 1 to adjust the air supply volume of the burner 3, and adjusts the air volume through the manual damper 3 to generate a flame zone 4 and burn The generated heat is transferred to the fire pipe 5 through radiation and convection, and then transferred to the softened water 6 through the fire pipe 5, and then transferred to the heat...
