Operating Procedures for the Unit Torch

I need information on this too!

VIII. Preparations and checks before driving 8.1 The torch tower structure has been completed, and upon passing the inspection, it is ready for use. 8.2 The flare cylinder, flare burner, and ignition control system have been installed, and tests conducted by the manufacturer have confirmed that they meet the requirements for use. 8.3 The torch auxiliary systems (instrument air system, nitrogen system, fuel gas system, etc.) are ready. 8.4 The pipeline purging and pressure testing have been completed and meet the usage requirements. 8.5 The instrumentation system meets the operating conditions. 8.6 The electrical system meets the usage requirements. IX. Ignition Operation and Control 9.1. Ignition of the permanent flame: Open the valve on the pipeline leading to the permanent flame; once the pipeline is filled with fuel gas, ignite it using a surface detonation system on the ground. 9.2 Ignition of the surface deflagration system 9.2.1 Working principle Surface deflagration refers to the process in which fuel gas and air are mixed in a certain ratio; once they enter the explosion zone, they undergo small explosions upon contact with fire. The resulting flames travel at subsonic speeds along enclosed pipes to the top of the flare tip. 9.2.2 Key operating points: When venting air, first ensure that the pipelines for the fuel gas and compressed air supplied to the ground detonation chamber are unobstructed and have sufficient pressure; then connect the power supply to the igniter on the ground detonation chamber. Open ball valve C in the compressed air pipeline again (to full open), adjust pressure regulator A so that the pressure after the purified gas valve is set at 0.35–0.4 MPa, and then open ball valve E ； Simultaneously open fuel gas control ball valve D (fully open), adjust pressure regulator valve B to set the pressure behind the fuel gas valve at 0.1–0.15 MPa, and then open ball valve F (fully open) ； Compressed air and fuel gas mix in the deflagration chamber; once the mixture fills the entire deflagration tube (approximately 30 seconds later), the “ignition button” on the igniter panel is pressed to start the ignition process. When vibrations occur, blue flames can be seen through the observation hole in the deflagration chamber, indicating that the ratio of compressed air to fuel gas has been adjusted properly and that the deflagration tube has been ignited. The three deflagration tubes will then ignite the corresponding permanent lights. 9.3 Ignition of the flare tip 9.3.1 Open the nitrogen inlet valve to purge the flare tower ； 9.3.2 Open the gas inlet valve and fill the flare stack with fuel gas ； 9.3.3 Once the fuel gas rises to the torch burner, it is ignited by the pilot flame. Note: The torch cylinder must be maintained at a slight positive pressure to prevent air from entering it, which could cause backfire! 9.4 Operation and Control of the Torch System: The torch tip must remain free from air ingress at all times during operation. Do not introduce oxygen-containing gases into the torch to prevent the formation of flammable mixtures in the pipeline system. If there is oxygen in the system, it should be purged with nitrogen before connecting to the flare tip. The gas purge points, FI-71101 and 71102, should be checked regularly to ensure that they operate within the purge flow rate range specified by ECEC, namely at a flow rate of 1 meter per second. The torch tip cannot collect liquid. At high flow rates, if the vent valve is open, the liquid plug at the flare tip can create high backpressure on the valve mechanism. When the liquid flows at high speed, it generates high pressure in the piping components such as elbows, and is then ejected at the top of the flare pipe. The Torch KO tank V-701 is used to collect liquids before they enter the torch. LI-71208 and LG-71209 can display the liquid level on KO tanks. These two devices should be checked regularly, and any liquid found should be drained.

Ours is a ground torch; the simple operation involves using nitrogen to displace the air, lighting the permanent flame, and filling the water seal tank with water to a level of 50–70 mm of water column； First, purge with nitrogen and open the primary vent; that’s sufficient. If black smoke appears, turn on the steam
