What could be the cause of a small uneven pilot flame?

More specifically, the problem is usually that an insufficient amount of gas is flowing through the pilot orifice. This is generally caused by one of two things: Poorly adjusted gas valve, Foreign debris inside of the pilot tube.

What are the two main types of burners?

Burner types

gas and diesel burners.
ultra-low emission burners.
low emission burners.
older-style burners.
open fires.

What are the three classifications of burners?

Burner Types
- Direct Fired Burners.
- Regenerative Burners.
- Radiant Tube Burners.
- High Thermal Release (HTR) Burners.
- Self-Recuperative Burners.
- Ladle, Tundish Stations.
- Low Temperature Regen (LTR)
  
  How many types of burners are used in the heater?
  
  What types of furnace burners are there? There are three primary types of furnace burners installed in homes: Conversion, Inshot, and Upshot. Conversion burner – A conversion burner actually converts one type of fuel to another before mixing it with air.
  
  How does a standing pilot work on a gas burner?
  
  On a standing pilot model we still use a thermocouple, but in a different way. The pilot valve is also built into the combination gas valve, so there’s no more “B” cock. To light the pilot, you hold down the button on the gas valve to start the flow of gas to the pilot burner.
  
  What should the pilot flame be in a gas oven?
  
  A correctly adjusted pilot flame is steady and blue, between 1/4 and 1/2 inch high. If the flame goes out repeatedly, or if it’s yellow at the tip, it’s getting too little air. If there’s a space between the flame and the pilot feed tube, it’s getting too much air.
  
  Why is the pilot not working on my gas oven?
  
  Most modern gas ranges use an electronic pilot igniter to start the pilot. If the pilot flame is properly adjusted, but the flame doesn’t ignite the burners, the problem is probably in the flash tubes that run from the pilot to the burners. These tubes may be blocked by spilled food from the burners.
  
  What should the flame look like on a gas range?
  
  The flame of gas range burners should be steady and slightly rounded, with a light-blue tip. The flame should be quiet and should respond to adjustments made at the control knobs. Most burner troubles can be quickly solved by adjusting the air shutter mixer plate, which is located at the end of the burner tube near the knob controls.
  
  What happens when the pilot flame goes out on a gas heater?
  
  A thermocouple is connected to a shutoff valve and is heated by the pilot flame. As long as the electrical current in the thermocouple energizes the coil in the safety valve, the gas can flow. If the flame goes out, the thermocouple will cool off and stop the current flow. This will cause the safety valve to close and stop the gas flow. pg 735-736
  
  Why is the flame in my gas burner pulsing?
  
  On 2018-12-26 by (mod) – flame in my gas range burners is pulsing. Please understand that it’s impossible for us to make an accurate diagnosis of a fuel gas safety Problem by a brief e-text. Pulsing gas pressure could be a problem with the regulator. Also variations in combustion air or drafts around the heater an cause apparent gas flame pulsing.
  
  What makes the flame visible on a gas grill?
  
  The final step is into the burners and out through the burner ports to make the visible flame. Above the burners, you have some type of barrier that protects the burners and helps to distribute the heat. The barrier catches drippings from foods so they can be burned off by the heat of the grill .
  
  Why does the pilot light on my furnace keep going out?
  
  The thermocouple is the copper rod the pilot flame directly hits. Sometimes it’s referred to as the “flame sensor.” It’s a safety mechanism that shuts the gas off should the pilot go out. If the thermocouple fails to shut off the gas, all the gas flowing through the furnace could get into your home.
