NOx-Related Project List :
Fluid Bed SNCR Optimization - Confidential Client
Customer was experiencing marginal environmental compliance, short injector life, and chemical scaling. The facility requires NOx reduction in the order of 80%. Changes were made to the basic process to eliminate the chemical scaling, and new injectors were supplied to improve injector service life and dispersion.
Kauai Power Partners Project Kauai, Hawaii
Scope: Design and Supply of a Dry Urea Handling System which creates a urea solution from dry urea. Fully shop prefabricated with PLC controls. Fabricated, pre-commissioned, and shipped 11 weeks after Approvals. Commercial operation since mid-'02.
Martell Cogeneration Facility Martell, CA
Scope: Process Optimization and equipment upgrades for an existing SNCR system at this 15MW wood fired unit. Unit demonstrated a detached stack plume from excess ammonia slip. Included furnace temperature profiling, dual fluid nozzle supply, and an atomizing air distribution system.
Gloucester County Resource Recovery Facility Westville, NJ late 200 and early 2001
Scope: Project Engineer and General Contractor for the installation of an SNCR system and Continuous Emission Monitoring System upgrade. Included the expansion of the compressed air system and the supply of dual fluid injection nozzles to replace the OEM equipment. New nozzles showing much greater service life and 25-30% lower reagent consumption. Design improvements also expected to reduce/eliminate localized corrosion to boiler tubes.
South Broward Resource Recovery Facility Ft Lauderdale, FL mid 2000
Scope: Project Engineer and General Contractor for the installation of an SNCR system at this 90MW refuse to energy facility. Design activities: civil, mechanical, electrical, compressed air addition. Installation activities: bid package development, contractor selection, and construction management.
North Broward Resource Recovery Facility Pompano Beach, FL mid 2000
Scope: Same as for South Broward work nearly identical and executed simultaneously.
Baltimore RESCO Baltimore, MD - 1999
Scope: Lead Project Engineer and Engineer-of-Record for a large ($40 MM) air pollution control retrofit project, which included expansion of their existing SNCR system.
Westchester RESCO Peekskill, NY 1998
Scope: Lead Project Engineer and Engineer-of-Record for a large ($68 MM) air pollution control retrofit project, including a new SNCR system.
Ridge Generating Station Lakeland, FL
Scope: Tested generic urea reagents as a substitute for the more expensive, proprietary, reagent. Test was successful leading to a similar conversion at 11 other facilities.
Shasta Energy Anderson, CA 1989
Scope: Project Engineer for the design and installation of an SNCR system at this 60MW wood fired plant.
Wheelabrator Millbury Millbury, MA 1986
Scope: Project Engineer for the design, installation, and testing of an SNCR system at this 45MW refuse to energy facility. This was a temporary demo project to test the performance of the system prior to installation elsewhere with commercial and regulatory guarantees. This was the first installation at a large municipal waste-to-energy facility in the US.
About DNT's Principal :
David Wojichowski, Principal and Project Manager of DNT, is a foremost expert on the design, installation, and operation of Selective Non-Catalytic Reduction (SNCR) techniques. This unique combination of sound technical understanding and real-world commercial experience is now being made available to the electric power and industrial boiler markets through De-NOX Technologies.
David's experience as Project Manager included the responsibility for the design and installation of urea and ammonia-based SNCR systems at seven small power generation facilities including the very first in the USA on a Municipal Solid Waste to- Energy facility.
