The late G. Bickley Remmey, founder of Bickley Furnaces, Inc., was a great innovator in the kiln and burner design field. I look back on his way of thinking often when I am working on a technical problem, and I try to imagine how he would solve the problem.
One of the simplest systems available to automatically proportion the flow of fuel and air, the ratio regulator has been used for decades and continues to achieve wide acceptance because of its simplicity, low cost and accuracy
Fuel fired kilns depend on a variety of means to control the burner air-to-fuel ratio. These systems vary considerably, but all of them require a good understanding of the concepts of flow and pressure.
