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.

stationary source air pollution control

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.

combustion system pollution control

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. Holds a patent for advance mixing technology, near field far field (NF³) mixing which can be applied to overfire air and other furnace and flue gas injections. It enables simultaneous injection near the wall and far into the flow. It is being commercialized by White Cliff Technologies, LLC.

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.

combustion control


combustion control system

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.

combustion control


combustion problem

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.

emission control device

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.

emission monitoring


flue gas

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.

fossil fuel


wood burning

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.

nitrogen oxide treatment

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.

particulate pollution process

He has provided service engineering for Process Combustion Control (PCC) Corp. PCC provides oil, methane and propane fired burners and thermal oxidizers.

propane combustion

He performs computational fluid dynamics modeling using Fluent™ simulating furnaces and ducts including chemical reaction and particle tracking; process modeling using Chem CAD and Aspen; and heat and mass balances using spreadsheets.
