Cooling Technology

Over the last few years an increase in the calorific value of the waste has been observed at our waste-to-energy facilities. Wheelabrator Technologies, Inc. in conjunction with Von Roll/Inova decided to install a zone of water-cooled grate blocks at the Millbury Massachusetts waste-to-energy facility as a pilot program. Common in Europe these water-cooled grate blocks address the issue of higher BTU waste and increase the overall life expectancy of the blocks compared to regular air-cooled grate blocks. This technical paper provides an overview on the installation, operation, and maintenance of a zone of water-cooled grate blocks. Discussed are the procedures for evaluating the overall project and some of the challenges we resolved.

The Impact

Hennepin Energy Recovery Center (HERC) is a waste to energy facility owned by Hennepin County and operated by Covanta Energy. HERC has been in operation since 1989. The facility burns 365,000 tons of residential and commercial solid waste per year and generates about 34 mega-watts of electricity that is sold to Xcel Energy. HERC is located on the north side of downtown Minneapolis in the Historic Warehouse District, a neighborhood that is changing from industrial to a more commercial/residential mix with loft conversions and construction of new condominiums. The Minnesota Twins baseball team is also siting a new stadium in the parking lot immediately southeast of the facility. The potential for odors from the tipping floor of the facility affecting the neighborhood has become more of a concern due to the changes in the neighborhood. In March 2004 the County began an odor study. This included developing baseline information on odors from HERC and from the surrounding community by conducting daily odor monitoring at select points on the facility property and throughout the community: • Determining how far odors from HERC migrate into the community. • Quantifying detected odors using a Nasal Ranger. • Determining the factors that contribute to these odors. • Developing a method of controlling these odors. • Continued monitoring to determine the impact of mitigation methods. Odors detected were characterized as garbage odors, garbage-related odors, and neighborhood odors. Baseline data showed that while garbage odors from HERC were mostly undetectable beyond the perimeter of the property, there was room for improvement in decreasing the presence and intensity of these odors. The tipping hall was designed to operate under negative pressure to control odors, however the entrance and exit doors were always open and a negative pressure could not be maintained.

Keeping Up With Growth by Recommitting to a Long-Term Waste-to-Energy Future

The Solid Waste Authority of Palm Beach County (Authority) has owned the North County Resources Recovery Facility (NCRRF) since 1989, producing clean, economical and renewable energy from refuse derived fuel while preserving precious landfill space. As with any facility as it approaches the end of its first 20-year operating term, the Authority found it necessary to initiate a comprehensive refurbishment to ensure its continued effective operations. The operating agreement between the Authority and the Palm Beach Resource Recovery Corporation (PBRRC), a subsidiary of Babcock & Wilcox (B&W), is set to expire concurrently with the end of the this 20-year term. The Authority acknowledged that PBRRC has unparalleled institutional knowledge of the NCRRF and, as such, took the opportunity to renegotiate its operating agreement with PBRRC for an additional 20-year term. The Authority was also able to build into the new operating agreement conditions for PBRRC to provide assistance to a third party design-builder performing the refurbishment. Additionally, understanding that B&W produced many of the key combustion unit components of the original NCRRF construction, the Authority worked into the new agreement terms for B&W to provide several essential components for the refurbishment that will be installed by the design-builder. When the refurbishment is completed in 2011, the Authority will still only have disposal capacity through 2021 with its existing landfill. To be able to keep up with rapid growth in Palm Beach County, the Authority has initiated the due diligence phase for the development of a new mass burn waste-to-energy facility and landfill that will expand the disposal capacity of the Authority’s system for more than 100 years.

Olmsted County is currently expanding their existing waste-to-energy facility in Rochester, Minnesota to add a third mass burn waste combustor. The new unit will have a capacity of 200 TPD, effectively doubling the size of the existing capacity. This paper will discuss some of the unique aspects of this project and review the current status. Some of the interesting and unique features to be discussed include: 1. Environmental Permitting – The county decided to do a voluntary EIS. 2. Project approach – The county is using a Construction Manager at Risk approach for construction of the facility. 3. Engineering – The engineering scope includes several separate procurements of major equipment packages, balance of plant design and several auxiliary projects related to the ‘utility’ system. 4. Operator Collaboration – Olmsted County is one of a few public owners that operate their facility. Their knowledge of the existing facility and of operating a mass burn facility has been used extensively in the planning and design of the new unit.

After sixteen years of operation, it became apparent that the pit fire protection system installed during construction of the Spokane Regional Waste to Energy (WTE) Facility (1989–1991) was inadequate. A risk analysis was performed by Creighton Engineering Inc., a fire protection consulting firm, hired by the Spokane Regional Solid Waste System (Regional System) and Wheelabrator Spokane Inc. With input from Spokane County Fire District 10 and the City of Spokane Fire Department, a replacement supplemental fire protection system was designed and ultimately installed. This paper will describe the problems with the once state of the art fire system and the planning, design and installation of the new system.

Municipal Waste Combustor

Abstract The SEMASS Resource Recovery Facility (SEMASS) is a processed refuse fuel (PRF) waste-to-energy plant serving much of Southeastern Massachusetts. Units 1 and 2 at the plant were designed with spray dryer absorbers (SDAs) and electrostatic precipitators (ESPs). A review of historical data from the plant indicated that in order to comply with the Environmental Protection Agency’s Municipal Waste Combustor (MWC) Rule (40 CFR Part 60, Subpart Cb), which is known as the Maximum Achievable Control Technology (MACT), improved emission performance would be required from the flue gas cleaning system on Units 1 and 2. A pilot test program was conducted which led to the installation of COHPAC, or COmpact Hybrid PArticulate Collector units (i.e. flue gas polishing devices) downstream of the ESPs on these two combustion trains. The COHPAC units were successfully started up in June, 2000. In addition to these modifications, it was determined that further control of mercury emissions would be required. A system to inject powdered activated carbon into the flue gas was added to the plant. This paper describes that carbon injection system. A comparison between test data obtained at SEMASS is made with predictions based upon the EPA testing at the Ogden Martin Systems of Stanislaus, Inc. Municipal Waste Combustor Facility near Crows Landing, California and the EPA testing at the Camden County Municipal Waste Combustor in Camden, New Jersey. These are waste-to-energy plants, the former utilizing an SDA and a baghouse while the latter contains an SDA followed by an ESP. In addition, the effect of carbon injection location upon mercury reduction was investigated. The results of that study are also included.

Broward County (the County), which is located on the southeast coast of Florida, is currently faced with an ash management and metals recovery decision. The County has two mass burn resource recovery plants and they process a combined total of approximately 1.65 million tons of MSW. The ash residue from these two facilities is currently landfilled. At one facility, the South Broward Waste-to-Energy Facility (the South County Facility), ferrous was being recovered at the ash monofill using mobile equipment, as the plant was not equipped with metals recovery equipment. But as market prices dropped, so did the ferrous metals recovery. This has adversely affected the useful life of the ash monofill, owned by the County. The County is looking for a cost–effective alternative for an on–line metals (ferrous and non–ferrous) recovery system.
