The problem of the permanent light in the heating furnace
Thread Content
The pilot light of the heating furnace should remain lit as required. Everyone, please participate: Is the permanent light in your heating furnace kept burning? If it goes out, what are the possible reasons?
The furnace pilot light must remain lit during both normal and emergency shutdowns. If it goes out, there may be the following reasons: 1. The gas nozzle of the perpetual light is blocked. 2. The flame arrester of the everlasting light is blocked. 3. The gas has no pressure.
Actually, it’s not the case in all cases; some refineries also have a low-pressure interlock for the pilot flame fuel gas, only the interlock value is a bit lower than that of the main burner.
It goes out when the machine stops. . . What other reason could there be? . . . . The closed-loop circulation of the device is a temporary measure; who can manage to have lights on without incurring any costs or using any fuel, while still achieving benefits? :lol
Once the heating furnace is lit, it can be left off.
Is the permanent light of our furnace’s heating unit kept lit? When the furnace was just started, it would go out occasionally; the main reason was improper adjustment of the flue dampers and air valves. There may be several other reasons for the shutdown: 1. Clogged pipelines 2. Valve failure 3. Flame arrester failure 4. Excessively low temperature, causing the fuel or gas to freeze 5. Clogged nozzles

Our company requires that the pilot light of the heating furnace remain lit at all times, and the pipeline for this pilot light leads from in front of the fuel control valve of the heating furnace.
The permanent light is essential for the safe operation of the heating furnace, and it must not be turned off under normal circumstances. The reasons for shutdown are generally blockages at the burner nozzle of the pilot light, blockages in the air supply to the pilot light, and gas containing liquid.
The extinguishment may be due to the following reasons: 1. Clogged burner； ⒉Flame arrester clogged ； ⒊The self-standing regulator on the pipeline is blocked ； ⒋Other valves on the pipeline are blocked.
The requirement is for continuous lighting, but it seems that too many lights can affect the temperature of the furnace chamber and the surface temperature of the furnace tubes; therefore, we installed them at intervals!
In normal production, the permanent light should not be turned off; it can be turned off during shutdowns.
If purging is required during a shutdown, then the operation must indeed be stopped. Other reasons include gas issues, or serious situations such as leaks of flammable gases near the heating furnace, fires, and explosions
A permanent light is lit at the start of operations and must not be turned off during normal production, as this is for safety reasons. Some perpetual lamps are used in chain systems, while others are not; the decision is made based on the actual production conditions.
Another reason for shutdown could be a false alarm from the flame detector; we often encounter this kind of issue.
The constant-flame burner in my setup is equipped with a low-level interlock; its setting is lower than that of the main burner. After the main pipeline splits off, there is a flow meter and a control valve in each branch
