EOS Series Biomass Gasification Boilers

AESI EOS Series Biomass Gasification BoilerEOS Series Biomass Gasification Boiler

The EOS series of biomass gasification boilers from AESI combust and gasify solid biomass fuels, range in output from 600,000 BTU/hr to 20,000,000 BTU/hr, and produce hot water, superheated water, and saturated steam for a variety of thermal needs. The EOS series is highly efficient, low in maintenance, and completely automated.

AESI’s biomass gasification boilers are based on European technology developed and enhanced for over 50 years by Italian-based Uniconfort, an ISO 9001 company, and exclusively fabricated by AESI in the United States. AESI and Uniconfort lead the industry in providing modular, reliable, and efficient biomass gasification solutions, services, and technologies.

The EOS series is designed for gasifying biomass with moisture levels up to 75% on a dry-basis and is well suited for agricultural biomass with high ash content. Automatic cleaning and ignition systems provide low maintenance and unattended operation. With a two-part hybrid combustion grate, (the first part is fixed and the second is moving for flexible combustion) the EOS series efficiently combusts different types of biomass fuels with low emissions.

EOS Series Highlights

High Efficiency

EfficiencyHigh exchange surface of the exchanger and low smoke temperature guarantees high yields of up to 93%.
