The purpose of this project is to study the technical and economic feasibility of conversion to coal with possible implementation of cogeneration at the central power plant of the New York Institute of Technology Central Islip (NYIT CI) campus. The existing facility contains five moderate pressure (155 psig) 60,000 pph boilers installed in 1953-1954 which were originally designed for coal firing. Among the several systems assessed, three potential projects were identified as having economic merit and conceptual designs for their implementation were developed. The final decision as to which should be pursued must await a final determination of environmental issues related to sulfur dioxide emissions and manufacturer recommendations on the ability to reconvert one of the existing boilers back to coal. The three projects, in order of economic merit, are as follows: (1) reconversion of one of the existing 60,000 pph stoker boilers back to firing coal; (2) installation of a new 60,000 pph stoker fired, high pressure coal boiler with a 2300 kW backpressure steam turbine, the turbine to provide some cogeneration capability. Compliance, low sulfur, coal is to be burned; (3) installation of a new 50,000 pph, low pressure, firetube, fluidized bed combustion (FBC), boiler burning high sulfur coal but including sulfur dioxide capture. The first two projects are predicated on the burning of a compliance, low sulfur, coal. This may be allowed under ''grandfather'' clauses in the regulations that permit such burning in boilers that once fired coal. If not permitted, the installation of the low pressure FBC boiler would be the only remaining viable coal conversion option. Though it has a smaller payback, it still provides significant savings to the college.
