Boiler Efficiency and Combustion | Spirax Sarco

Because the atomisation is produced by the rotating cup, rather than by some function of the fuel oil (e.g. pressure), the turndown ratio is much greater than the pressure jet burner. Advantages of rotary cup burners: Robust. Good turndown ratio. Fuel viscosity is less critical. Disadvantages of rotary cup burners: More expensive to buy and maintain.

Turndown ratio - Wikipedia

Oil burning boilers can achieve turndown ratios as high as 20, but typically only 2 to 4 with conventional burner designs. Small domestic "vaporising" (i.e. burning kerosene or 28 second oil) burners do not modulate at all and are relatively inefficient. Boilers using the pressure jet type of burner, i.e. with a fan, (usually with 35 second oil) can achieve a turndown ratio of 2, while the rotary cup type burner can …

Why Does My Boiler Make A Banging Noise When Firing Up

Delayed ignition is a problem that's common in gas boilers that use pilot lights (as opposed to electronic ignition systems). You see, during normal operation, when a gas boiler receives the call for heat, the gas valve opens and releases a small amount of gas into a sealed combustion chamber via small "jets".

Rotary Cup Burner ・Boiler Burner・SUNFLAME.CO.,LTD.

By the development of the third generation, the Sunflame rotary cup burner managed to widen its turn down ratio. The direct driven rotary cup burner regulates the speed of the cup rotation according to the volume of the fuel flow and can enjoy large turn-down ratio, minimizing unnecessary start/stop operations of the boiler according to the steam pressure. This system offers the best atomization at every range, …

How Do Burner Combustion Control Systems Work? - CrossCo

They power package boilers, start up larger furnaces with fluidized beds and grates, and heat many other processes. Larger burners have Combustion Control Systems (CCSs) which should be tuned periodically. To understand how to tune a gas and/or oil (usually #2 Diesel oil) burner, it helps to first understand how and why they work the way they do.
