A wood-fired gas turbine system for specialized cogeneration applications is being developed. The System is based on a patented pressurized, suspension-type combustor. A demonstration of the technical and economic viability of the integrated wood-fired System is being funded by the U.S. Department of Energy through Morgantown Energy Technology Center and the National Renewable Energy Laboratory, and Power Generating Incorporated, and the plans are underway to build and operate an approximately 400 kW prototype system at the Western Research Institute’s facilities in Laramie, Wyoming.

As a preliminary step in the Demonstration Project, a limited on-site test program was conducted to characterize the products of combustion in an atmospheric pressure, wood-fired combustor. Particulate and gas sampling were performed at a major sawmill complex, where an atmospheric pressure version of the combustor was operated on dry sawdust and planer shavings. An air-cooled probe was also exposed to the combustor environment to collect deposit samples at temperatures expected in the gas path of the turbine of the system. Particulates and deposits were analyzed for major ash constituents and the particle size distribution was determined.

This paper describes the results of the tests and other pertinent data.
