g a biomass

fired fluidized bed boiler to

provide process steam as well as steam to run a turbine and generate electricity. Maximum capacity would be250,000 lb/hr of steam, with the capability to operate at least as low as 50,000 lb/hr for extended periods (i.e.,

days or weeks). The majority of the fuel would be clean, wet (‘50% MC) wood fuel, blended with a maximum of

20% urban and/or agricultural wastes. Can you provide such a boiler, and, if yes, can you provide references of

installed examples of boilers you have provided that operate in this way? The overall project would be permitted

through the U.S. EPA, and the exhaust would have to meet best available control technology requirements.

Thanks, and please call me if you have any questions.

Here’s the contact I had at EPI (now Outotec).

Please let me know if there’s anything else you need.

Thanks.

Hi Eric and thanks for the email. EPI, now owned by Outotec, does provide fluidized bed energy systems

capable of producing process or superheated steam. Our typical systems range in size from 20,000 lb/hr

up to 500,000 lb/hr in a single boiler. Our fuels list features hundreds of different fuels and certainly

wood, urban and agricultural fuels are on the list. EPI has also been a leader in setting the standards for

low emissions. The desire to turn down from 250,000 lb/hr to 50,000 lb/hr is something that you might

try to do with a gas fired boiler but solid fuel systems do not typically have that kind of turndown without

dropping the superheat temperature.

I will ask Eric Wesselman of our group give you a call to further discuss this project.

Thanks again for thinking of us.
