Combustion & Thermal Treatment
Combustion is one of the most significant industrial processes and also one of the most highly regulated. Combustion provides energy for process heating, reaction initiation, electricity generation, propulsion and transportation, food processing, fabrication, and waste treatment and destruction to name but a few applications.
Focus personnel have extensive experience in the design, evaluation, and operation of combustion systems and associated air pollution control equipment. This experience is the foundation of effective consulting for the full gamut of air pollution control systems. Focus is effective at evaluating alternative and comparable energy sources.
With our strong process and regulatory background, Focus engineers are well suited to perform technology assessment studies for energy consuming process systems. Our engineers conduct studies for energy efficiency, throughput optimization, increased operational capacity, use of alternative fuels, and emissions impacts. Focus engineers design and evaluate fans, ductwork, hooding, and general air handling systems.
Application of Combustion Equipment
Focus has experience with the following combustion equipment applications:
- Hospital / Medical / Infectious Waste Incinerators (HMIWI)
- Hazardous Waste Combustors (HWC)
- Aggregate and Cement Kilns
- Halogen Acid Furnaces
- Industrial Boilers
- Low Temperature Thermal Treatment
- Commercial / Industrial Solid Waste Incinerators (CISWI)
- Municipal Waste Incinerators
- Sludge Incinerators
Emissions Estimates and Waste Characterization
Focus engineers have extensive experience estimating emissions from processes including estimation of removal efficiencies across various types of air pollution control systems using both theoretical and real world estimation techniques. Focus maintains a stack testing database to verify emissions estimates generated for specific applications. These estimates form the basis for air permit applications and design.
For the proper design of any treatment system, an accurate accounting of all process inputs is an essential requirement. Focus has developed special expertise and engineering analytical tools to ensure emissions and wastes are adequately characterized, categorized, and inventoried.
Emission Control Systems Engineering
Emission control systems must be engineered to capture before they can control. Focus engineers understand control techniques, capture velocities, and hooding configurations necessary to capture hot, buoyant plumes, hazardous gases, abrasive dusts, etc. We engineer emission control systems starting at the point of capture, through the hood, the adjoining ductwork, the many transitions, the control device, the fan, and the exhaust. We ensure pressure loss, material abrasion, material consistency (wet or sticky), and conveying velocity are taken into account. Relevant applications include particulate collection, mercury and other metal controls, acid gas scrubbing, organic emissions controls, and nitrogen oxide emission controls.
