We are looking at the bottom section of the Taylor Energy gasification reactor. A Pulse-Deflagration-Burner, provided by Pulse Combustion Systems (PCS of Payson, Arizona,) is attached to the bottom of the gasifier and is used to input hot-air (or oxygen-enriched air) that is employed for autothermal gasification for carbonaceous feeds. Â Note the PCS pulse-burner has an internal flame-can contained within a stainless steel housing that serves to reduce the noise generated by the pulse-burner, which tends to be a bit loud.
