TRW ADVANCED SLAGGING COAL COMBUSTOR
FOURTH QUARTERLY PROJECT PROGRESS REPORT
AUGUST 1989 THROUGH OCTOBER 1989
The TRW Advanced Slagging Coal Combustor Demonstration Project consists of retrofitting Orange and
Rockland (O&R) Utility Corporation's Lovett Plant Unit No. 3 with four (4) slagging combustors which will
allow the gas/oil design unit to fire 2.5 sulfur coal. The slagging combustor process will provide NOx and
SOx emissions that meet NSPS and New York State Environmental Standards.
TRW-Utility Demonstration Unit (UDU) is responsible for the implementation of program policies and
overall direction of the project. The program was established, project activities were monitored, and progress
is reviewed constantly to ensure that the project is advancing toward its set goals in an orderly and cost-
effective manner. The necessary inter-organization coordination and interface communication were provided
by TRW-UDU management during this quarter. The team participants are TRW, SWEC and O&R Utilities.
DOE and program sponsors are informed of the project status by TRW(UDU) through quarterly, monthly
project reports, cost and schedule status reports (program deliverables).
TRW-CBU scope of work includes the engineering, design and supply of the slagging combustors, coal and
limestone feed systems and a control system for these components.
Stone & Webster Engineering Corporation (SWEC) has the responsibility of performing the day-to-day project
management function under the direction of TRW(UDU). SWEC has in place an organization to perform
budgeting, cost and scheduling, performance measurement and general administration required to perform and
support the engineering design, purchasing, construction, testing and analysis of the project.
TRW Cleveland Program objective, which is sponsored by the Ohio Coal Development Office (OCDO), is
to demonstrate sulfur dioxide emissions control by pulverized limestone injection into the entrained coal
O&R's primary responsibilities are environmental licensing and permitting activities, transmitting technical and
operating data to team participants, providing the operating staff at their facility to implement the test
program and participating in analyzing the test results. O&R has provided management and control to ensure
that the plant preparation activities are technically adequate and are on schedule.
During this report period, the design activities for all systems progressed to permit the release of specifications
and requests for proposals. Award of contracts for long-delivery items and major equipment are being placed
to meet the revised program schedule.
1. EXECUTIVE SUMMARY
During this reporting period, Phase I and IIA activities on TRW's Slagging Coal Combustor Utility
Demonstration Program continued.
At the Advisory Committee Meeting held on August 10, we met with the program sponsors to present the
status of the program. A capital equipment cost estimate projected a significantly higher cost than the
original 1988 estimate. A detailed review of the significant cost items was made at the 40% Project Review
Meeting with DOE on August 17. At the DOE's request, a review team was formed to examine the entire
project scope and costs to firm up the estimate. TRW committed a "Tiger Team" to lead up this effort with
a goal to complete the study in October 1989. The primary task of the "Tiger Team" was to "harden" the
cost estimate to complete the project and perform an accurate assessment of the entire program so that there
is a higher confidence level in the costs.
Here’s what’s next.
