The objective of the Healy Clean Coal Project is to demonstrate the integration of an advanced combustor and a heat recovery system with both high and low temperature emission control processes. Resulting emission levels of SO2, NO(subscript x), and particulates are expected to be significantly better than the federal New Source Performance Standards. (VC).

This Quarterly Technical Progress Report is required under U.S. Department of Energy (DOE) Cooperative Agreement, Section XV, {open_quotes}Reporting Requirements{close_quotes} and Attachment C, {open_quotes}Federal Assistance Reporting Checklist{close_quotes}. It covers the period of October 1, 1994 through September 30, 1995. The primary objective of the HCCP is to conduct a cost-sharing project that will demonstrate a new power plant design which features innovative integration of an advanced combustor and heat recovery system coupled with both high and low temperature emission control processes. The parties anticipate that if the demonstration project is successful, the technology could become commercialized in the near term and will be capable of (1) achieving significant reductions in the emissions of sulfur dioxide and the oxides of nitrogen from existing facilities to minimize environmental impacts such as transboundary and interstate pollution and/or (2) providing for future energy needs in an environmentally acceptable manner. The primary equipment elements comprising this new power plant design includes entrained combustion systems coupled with a boiler which will produce low NOx levels, function as a limestone calciner and first stage SO2 remover in addition to its heat recovery function; a single spray dryer absorber vessel for second stage sulfur removal; a baghouse for third stage sulfur and particulate removal; and a lime activation system which recovers unused reagent from particulate collected in the baghouse. The emission levels Of SO2, NOx, and particulate to be demonstrated are expected to be better than the federal New Source Performance Standards (NSPS).
The Healy Clean Coal Project, selected by the US Department of Energy under Round 3 of the Clean Coal Technology Program is currently in construction. The project is owned and financed by the Alaska Industrial Development and Export Authority (AIDEA), and is cofunded by the US Department of Energy. Construction is 99.8% complete and scheduled for physical completion on November 15, 1997, with startup activity concluding in early 1998. Demonstration testing and reporting of the results will take place in 1998, followed by commercial operation of the facility. The emission levels of nitrogen oxides, sulfur dioxide, and particulates from this 50 megawatt plant are expected to be significantly lower than current standards. The primary objective of the project is to demonstrate a new power plant design which features the innovative integration of an advanced combustor and heat recovery system coupled with both high- and low-temperature emission control processes. Equipment includes entrained combustion slagging systems coupled with a boiler which will produce low NOx levels, and function as a limestone calciner and first-stage SO2 remover in addition to its heat recovery function; a single spray dryer absorber vessel for second-stage SO2 removal; a baghouse for third-stage SO2 and particulate removal; and a lime activation system which recovers unused reagent from particulate collected in the baghouse.

During this past quarter, engineering and design continued on the boiler, combustion flue gas desulfurization (FGD), and turbine/generator systems. Balance of plant equipment procurement specifications continue to be prepared. Construction activities commenced as the access road construction got under way. Temporary ash pond construction and drilling of the supply well will be completed during the next quarter.
