The paper reports the status of three EPA biomass-to-energy development and demonstration projects. EPA's Air Pollution Prevention and Control Division is participating in research, development, and demonstration projects with goals of coverting biomass energy to electrical power, waste utilization, pollution alleviation and energy conservation. Each project is aimed at demonstration of the technical, economic, and environmental feasibility of an innovative energy conversion technologic. The first project is a demonstration of a design by Thermal Technology, Inc. and Mech-Chem and Associates, Inc. that consists of a fixed-bed gasifier, a gas cleanup system, and a syngas and diesel engine. The second project is a continuation of the development of the Cratech, Inc. biomass-fueled integrated-gasifier gas turbine power plant. The third project is a demonstration of the ENERGEO, Inc. AGRI-POWER 200 biomass-fueled power plant that operates with an open Brayton cycle using fluidized-bed combustor and several heat exchangers to heat compressed air and drive a turbine/generator set. The system also discharges clean hot air that can be used for cogeneration.
