Turn down ratio is the maximum to minimum heat output.Turn down ratio for direct gas fired burners is 25:1, which means that the burner can modulate from 4% to 100% of full fire. Indirect gas turn down ratio is typically 2:1, which limits the heat output from 50% to 100% of full fire.

What range of values does intrinsic standoff ratio fall into?
The ratio of RB1 to RBBO is the intrinsic standoff ratio. It is the standoff voltage ratio to the power supply voltage.
What is the definition of hot work ratio?
The hot work ratio is the area ratio of the cast diameter and the pre-machined finished diameter.
What is the ratio of a boiler burner indicates the flexibility of the burner to cope with variations of boiler load without losing efficiency of atomisation?
turndown ratio
What is turndown ration?
Turndown ratio refers to the width of the operational range of a device, and is defined as the ratio of the maximum capacity to minimum capacity. For example, a device with a maximum output of 10 units and a minimum output of 2 units has a turndown ratio of 5.
What is turndown capacity?
Its is process term which means the reduced capacity w.r.t. the rated capacity. For example if plant rated capacity is x and turndown capacity is 85% that means 0.85x. And similarly the turndown ratio would be x/0.85x.
How can you make a Bunsen burner hotter?
By using the correct ratio of oxygen and fuel mixture. Opening the air hole in the Bunsen burner increase the oxygen which helps the flame burner hotter .
What is turn down ratio of oil fired boilers?
it is ratio of maximum air to minium air
What is the function of the barrel of a Bunsen burner?
The barrel of a Bunsen burner controls the amount of air mixing with the gas, affecting the flame's color and intensity. By adjusting the barrel, you can create a hotter, blue flame or a cooler, yellow flame for different heating needs.
What part of flame is hottest on a Bunsen burner?
The inner blue part of the flame is the hottest on a Bunsen burner, as this is where complete combustion occurs due to the optimal air-to-gas ratio.
What are nozzle mixing burners used for?
Nozzle mixing burners are used in combustion systems to mix fuel and air at the burner tip before combustion occurs. This design allows for precise control over the fuel-air ratio, which can result in efficient and controlled combustion processes. Nozzle mixing burners are commonly used in industrial applications such as boilers, furnaces, and heaters.
What causes a burner flame to be smoky and to separate from the tip of the burner?
A smoky burner flame that separates from the tip of the burner is typically caused by an incorrect air-to-fuel ratio. This can be due to a clogged burner or inadequate airflow. It can also be caused by a lack of proper maintenance or adjustment of the burner.
What is the most likely cause of flames that are lifting off the burner?
The most likely cause of flames lifting off the burner is insufficient air supply to the burner. This can lead to incomplete combustion and cause the flames to lift off. Adjusting the air mix ratio or cleaning the burner ports may help resolve the issue.
What is the function of the barrel of the Bunsen burner?
Control of the ratio gas fuel/air in the burner.
What is the collar on a Bunsen burner for?
The collar on a Bunsen burner is used to control the airflow to the flame. By adjusting the collar, you can change the ratio of gas to air, which can affect the size and intensity of the flame produced.
