Thermal Oxidizer Pilot:

Do I need to run my pilot continuously?
Not generally. John Zink Hamworthy Combustion burners are designed for stable operation with or without a pilot. However, your facility may have its own rules about continuous or intermittent pilot operation. If your burner appears to be unstable without a continuous pilot, the instability may signal a serious safety condition that must be remedied.

My standard ignition electric pilot isn’t working. What should I do?
In most cases one of the insulators has failed, dirty, or saturated with water causing the ignition rod to ground/short out. The pilot should be removed and inspected. You may need to perform a bench test to determine the location of any shorts. Check the orifice spud for blockage.  Consider replacing your standard ignition pilot with our newer technology High Energy Ignited Pilots such as our AG-HE™ series pilots.

Should my pilot tip be glowing red?
Yes, most John Zink Hamworthy Combustion pilot tip shields are designed to glow red when the air and fuel are adjusted properly.

Thermal Oxidizer Burner Tile:

 

Why is the tile so important to the operation of my burner?
The tile helps meter the combustion air, mold the flame shape and stabilize the burner flame.

Thermal Oxidizer Burner Gas Tips:

How do I clean my gas tips?
By hand, use a drill bit smaller than the port you intend to clean, and carefully oscillate the drill bit to remove the debris.
Caution: Do not enlarge the port.


Back to Top


What is the proper orientation of my gas tips, and why is it important?
The orientation and location of the gas tips are given on all John Zink Hamworthy Combustion burner drawings. The drilling pattern or slots on a gas tip are designed to shape the flame in a specific pattern. If the orientation or location of the gas tip are incorrect, flame impingement or instability can occur.

Back to Top


When should I replace my gas tips?
The gas tip drillings or slots erode over time due to particulate in the fuel. Corrosion also affects the tip over time. If the orifice is larger than designed or corroded, the gas tip should be replaced.

Back to Top


Why are my gas tips plugging, and what should I do?
First, identify the material causing the tips to plug. Liquids, particulate, unsaturated hydrocarbons, and H2S cause most plugging problems. Generally, knock-out pots are used to remove solids and liquids. Coalescing filters may be required if knock-out pots are insufficient.

Back to Top


Why is an ignition port on a gas tip important?
Ignition ports are used to stabilize the main body of the flame. In general, ignition ports are used to create a continuous, consistent ignition zone on the burner tile or diffuser cone for stability.
