Summary of Expertise:
|
Listed with other top experts in: |
|
He has developed combustion modifications for reducing emissions of CO, unburned hydrocarbons, NOx and SO2, and specified and designed post-combustion systems for the control of NOx, SO2, HCl, and PM. These systems have been both prototype and commercial. He can develop and apply strategies to comply with the new National Emission Standards for Major and Area Sources of Hazardous Air Pollutants.
|
|
|
He has designed multi-component air pollution control systems for NOx, SO2, CO a PM for both coal and wood combustion. These air pollution control systems have been for combustion systems with through puts from 16 MegaBtu/hr to utility boilers.
|
|
|
He is co-inventor of the Riley CCV burner, and holds a patent for NOx and CO control from waste combustors. He managed a program to select a low-NOx burner for a 400 MWe oil fired boiler. He was also heavily involved in the development of heat release and absorption models for design of industrial boilers.
|
|
|
He performs diagnostic analysis for industrial burners and boilers, and recommends changes to operation and control design. This has resulted in a regular clientele who rely on these services for trouble shooting and annual certification.
|
|
|
He performs diagnostic analysis for industrial burners and boilers, and recommends changes to operation and control design. During site visits the operation of the combustion system is analyzed and solutions are recommended. Each project results in a written report for the client's future reference.
|
|
|
He provides NaHCO3 injection systems for control of acid gases. As part of this service he has recently developed an injector for air in air born reagents.
|
|
|
He designed and operated emissions monitoring systems for NOx, SO2, CO, and O2 for prototype combustion systems. This included data analysis software to utilize the measurements. These systems included design of the gas conditioning and selection of the analysis instruments and data logging system.
|
|
|
He designed and developed combustion systems for coal, oil and gas for Riley Stoker (Riley Power). This included the development of the CCV burner from concept, through prototype and to eventual field installation.
|
|
|
He has developed burners for NOx coal combustion and staged combustion to control NOx emissions from waste fired boilers. His experience includes evaluating oil and gas fired burners for utility boilers. He has also designed and operated selective catalytic NOx reduction systems.
|
|
|
He is familiar with both baghouses and electrostatic precipitators (ESP). This has required specifying and operated baghouses for PM control from combustions systems. He has also evaluated the application of existing ESP to new systems.
|
|
|
He has provided service engineering for Process Combustion Control (PCC) Corp. PCC provides oil, methane and propane fired burners and thermal oxidizers.
|
|
|
He has investigated process for the control of mercury and other toxic metals. This work resulted in a patent for the thermal fixation of toxic metals in clays. He also recently developed an propretary injector which can be used for introducing sorbents for the capture of toxic metals.
|
|
|
While working for Riley Stoker he developed reburing to control emissions of NOx, CO, HC and dioxins from waste to energy plants. Later this transitioned into developing the computer simulation program for designing waste to energy furnaces.
|
|
|
He is the owners engineer for South Point Power. This required developing the air pollution control plan, the preparation of the Permit to install and certifying the plant for New Jersey renewable energy credits. He also provides combustion tuning services for wood fired boilers.
