Example Embodiment

[0014] Example 1

[0015] A new type of burner ignition device for a gas-fired heating furnace and its use method, which mainly consists of a gas supply main pipe 1 in front of the burner nozzle, a discharge pipe 2, a discharge stop valve 3, a sampling pipe 4, a sampling stop valve 5, and a pipe cap 6 , Rubber hose 7, ignition tube 8 form. When the heating furnace is turned on and ignited, the gas system should be purged and released first, and the release stop valve 3 should be opened. After 20-30 minutes of release through the release pipe 2, the sampling stop valve 4 and the pipe cap 6 should be opened to carry out the "explosion" test. Detect the amount of residual oxygen in the gas pipeline. After passing the test, connect the rubber hose 7 and the ignition tube 8 at the end of the sampling tube 5, put a lighter on the end of the ignition tube 8, open the sampling shut-off valve 4, and press the lighter switch. Form a stable flame at the end of the ignition tube 8, loose...

Abstract

The invention discloses a fire coal gas heating furnace nozzle ignition device and an application method, and belongs to the technical field of industrial furnaces. The fire coal gas heating furnace nozzle ignition device comprises a nozzle front gas supply mother pipe, a diffusing pipe, a diffusing check valve, a sampling pipe, a sampling check valve, a pipe cap, a rubber hose and an ignition pipe. The diffusing pipe is arranged at the end of the mother pipe and provided with two DN15 check valves and is used for the on-off states of a diffusing system. The sampling pipe is arranged between the two check valves and connected with the diffusing pipe. The sampling check valve is arranged on a pipeline of the sampling pipe. The pipe cap is arranged at the tail end of the sampling pipe, and after gas blowing and diffusing or nozzle ignition is over, the pipe cap is screwed at the tail end of the sampling pipe, and gas leakage is prevented. When the nozzle needs to be ignited, the pipe cap is unscrewed, one end of the rubber hose is arranged on the sampling pipe in a sleeving manner, and the other end of the rubber hose pipe is arranged on the ignition pipe in a sleeving manner. When the nozzle is ignited, the end of the ignition pipe generates a flame current with long flames, and the flame current serves as an ignition source of a heating furnace main nozzle. The fire coal gas heating furnace nozzle ignition device and the application method have the beneficial effects that operation and maintenance are simple; safety, practicality and reliability are achieved; and the investment cost is low.

Description

technical field [0001] The invention belongs to the technical field of industrial furnaces, and in particular relates to an ignition device for a burner of a gas-fired heating furnace and a use method thereof. The main function is to provide an ignition source for the burner and ignite each time the gas-fired heating furnace is ignited. Background technique [0002] The current heating furnace tends to be fully enclosed, and it is no longer necessary to set up a special ignition door or a large ignition hole next to the burner brick for ignition as in the past. Moreover, some industrial furnaces operate quite frequently and have a large number of burners. It is necessary to install an ignition transformer, ignition arc electrode, flame detector, automatic shut-off valve and other facilities in front of each burner. At the exit, the arc discharge will stop after ignition. As for the continuous heating furnace, once it is ignited, it is seldom shut down in a short time, but ...
