Conversion equipment.
(3) Conversion equipment. Conversion equipment includes equipment that converts solid waste into a fuel or other usable energy, but not beyond the point at which a fuel, steam, electricity, hot water, or other useful form of energy has been created. Thus, combustors, boilers, and similar equipment may be eligible if used for a conversion process, but steam and heat distribution systems between the combustor or boiler and the point of use are not eligible.
