Propane Air

Much like standby generaton for electrical backup power, customers may desire to have a backup in case their natural gas supply for boiler fuel, process support or building heat is lost. The solution is a propane air system. The challenge is that methane (CH4) and propane (C3H8) have different fuel densities and you cannot merely substitute one fuel without having separate point of use fuel nozzles for each application. The creative soltuion is to utilize a system that will dilute the propane with air creating a fuel density close to natural gas and allowing existing natural gas equipment to oeprate without the need for expensive modifications and fuel delivery systems (i.e., redundant piping one for natural gas and one for propane) throughout your facilty. A propane air system can help you:

  • Sustain critical process or life safety functions during severe weather.
  • Sustain critical process or life safety functions with an unreliable utility supply.
  • Disaster recovery, business continuity, emergency preparedness, etc.

Application Fit

If you think propane air may be a fit for your application, you should consider:

  • How much capacity do you need?
  • Does your local utility offer incentives for interruptible fuel delivery?
  • What sorts of permits are required?
  • Do you need to register the storage tank with federal authorities?
  • Who decides when you operate your propane air system and for how long?
  • Who takes care of managing fuel inventory in the propane tank?
  • Where should you site the equipment?
  • Do you have the expertise to operate and maintain the equipment (i.e., is it part of my core business)?

Many utilities offer incentives for customers that are willing to take fuel delivery on an interruptible basis. These incentives can help pay for a propane air system.
