| Fuel Mix through a given size Burner Head |
100% with venturi utilizing 100% primary air(i.e., no secondary air) |
150-180% with a good powerful blower. In other words, this system can push more combustibles through any given size head. In this regard it is often thought be the more efficient of the two systems. But keep in mind the extra fuel it pushes is not free. That is, you will pay for what you get. |

Plans for Low Pressure
(Natural Gas or Propane) System |
| The schematic below shows the low pressure "UV" safety system approximating what is current practice. It is not inexpensive but is designed to protect from the many dangers. I have contacted Stephen Abell from Abell Combustion, Inc. He is a competent engineer willing to guide you through this maze of safety issues (as of A.D. 2001). He sells a complete line of safety related gauges, mixers, solenoids, and controls.
"Abell Combustion, Inc., Meeder Equipment, and Joppa Glassworks, Inc. have no relations other than professional courtesy. Joppa Glassworks, Inc. and/or Dudley Giberson do not imply that these are the only folks out there who can help you with your gas safety issues. Look around locally and use these pages as a general guide to get help." |
