- Within the commercial sector, oil and natural gas are the predominant fuels used to meet the space-heating needs of schools, office buildings, apartment complexes, and other similar structures. In general, these buildings require firing rates of 1 to 10 million Btu/hr. The objective of this program is to demonstrate the technical and economic viability of a coal-fired combustion system for this sector. The commercial-scale coal-water slurry (CWS) fired space heating system is a scale-up of a CWS-fired residential warm-air heating system developed by Tecogen under contract to the Department of Energy (DOE), Pittsburgh Energy Technology Center. This system included a patented nonslagging combustor known as IRIS, for Inertial Reactor with Internal Separation. The combustor concept employs centrifugal forces combined with a staged combustion process to achieve high carbon conversion efficiencies and low nitrogen oxides generation. Along with the necessary fuel storage and delivery, heat recovery, and control equipment, the system includes pollution control devices to meet targeted values of SO₂ and particulate emissions. In general, the system is designed to match the reliability, safety, turndown, and ignition performance of gas or oil- fired systems. During the past quarter, installation of the slurry production facility and coal water slurry fired space heating system at the Illinois Coal Development Park`s High Bay Building was initiated. Installation is approximately 75% complete.
