Comfort Letters

It’s been a long time since I last posted here, but there really has not been much to write about. The EPA has now released a handful of ‘comfort letters’ allowing state DEPs and endusers to move forward with testing and long-term usage of engineered fuels. With these latest determinations, recognizing the value in diverting waste materials from landfill, the EPA seems to be giving a green light to move forward.
For many endusers across all industries that AF equipment in place, his will allow the fast tracking of existing AF programs. Other companies just starting out that are developing a program based on fuel price alone will struggle. There are many reasons for this to be true and really justifies a separate blog attempt in the future.
CFD
As always, we highly recommend CFD modeling the process ahead of time to gain a better understanding of the current process performance. Only then can you accurately establish correct location and injection velocities of a new fuel. New fuel customers should not only spent the time evaluating new fuel options but also examine the various CFD solutions that may apply. In the end, the technology is a valuable engineering tool.
Let’s hope we can curb our fossil fuel dependance further with this latest turn of events.
