Associated Physics of America has developed a gasifier for process gas applications like brick kilns.

EverGreen Gasification. Technology, LLC (EGT) is a wholly-owned subsidiary of Associated Physics of America, LLC (APA). EGT manufactures, markets and services gasification technology developed by APA. In conjunction with affiliated partners, EGT can provide turnkey gasification plant Engineering and Construction (E & C) Services. EGT can also assist Clients in procuring feed stocks, analyzing biomass samples, and test gasification for feasibility studies. EGT and APA’s team of Engineers, Scientists, and Technicians can assistClients in auditing and optimizing process heat systems.

APA’s gasifiers are Pressurized Downdraft style, which provides high gasification efficiency, low power consumption and long operating life Since the Combustible Gases can be “piped,” the gasifiers can be located at a distance away from the process.

The Beta Project
• PROJECT OBJECTIVE: Design, build and test a “Beta” Gasifier specially for
brick kilns.
• Over 1,700 hours of operation over 3 month period, over 550,000 lbs of
commercial-grade woodchips gasified.
• 2.6 Billion Btu’s delivered to one zone of a Tunnel Kiln (equivalent to 2.6
Million Cubic Feet of Natural Gas).
• 17% Increase in production with no additional increase in Natural Gas usage.
• Hardwood and pine chips tested.
• Estimated less than 5,000 lbs of Residue generated (blended with plant feed
clay).
• Operational and mechanical reliability of the gasifier and control systems
were tested.
• 27 new features in both the mechanical and software design are now
incorporated into the production units to: 1) maximize heat output, 2)
maximize mechanical reliability and 3) minimize maintenance requirements.
