The Resources to Provide Total Plant Solutions
Our comprehensive solutions target real economic improvement
within your processes. With thousands of installed systems, our
engineers and designers work together to address more than
just the immediate need. We focus our efforts on your entire
facility—from optimizing equipment to improving the bottom
line. John Zink Hamworthy Combustion is able to manage this
comprehensive approach because of our extensive resources.
Our People: Experts with unrivaled combustion and emissions
control experience know the process like no other. These experts
can combine our state-of-the-art combustion technologies with
any required post-combustion emission reduction technologies.
Our single-source, end-to-end emissions solutions will reduce
emissions and optimize operating costs.
Our Facilities: Our research and development center is the
largest and most advanced testing complex in the industry. These
exclusive resources allow us to push innovation, gain expertise,
and measure performance in an industrial-scale setting to better
replicate real-world conditions.
Our extensive Computational Fluid Dynamics (CFD) capabilities
play a key role in simulating the performance of our emissions
control technologies in your operating environment.
A John Zink Hamworthy Combustion Selective Catalytic
Reduction (SCR) system downstream of a wet scrubber
reduces NOx emitted into the atmosphere. It consists of
the following components:
+ Ultra-low NOx burners
+ Flameless combustion
+ Flue gas recirculation
(external or in-furnace)
+ Flue gas reheat
+ Oxy-fuel firing
+ Steam and water
injection systems
+ Air staging (OFA ports)
+ Bias firing
+ Oxidation catalyst
+ SCR (Selective Catalytic
Reduction)
+ SNCR (Selective
Non-catalytic Reduction)
+ A demister vessel to
dry the flue gas and
prevent any soluble
salts from entering
the catalyst bed
+ A direct-fired
flue-gas heater
+ An ammonia
injection section
with a static mixer
+ A catalyst bed
+ A vent stack
With our expertise and in-house capabilities, we can provide an integrated approach to meeting your emissions needs,
utilizing an array of effective emissions reduction technologies including:
Each situation is unique and each technology has specific capabilities
and requirements for achieving NOx reduction, making off-the-shelf
options less likely to deliver optimum results. That’s why our experts
assess not only each technology, but combinations of technologies for
your specific facility. It takes an all-encompassing expertise to custom-
engineer a system with multiple technologies. We take that know-how,
along with our understanding of your existing equipment, current and
expected regulations, operating costs and more, to design the most
effective and efficient emissions solution for your situation.
A Single Source For Emissions Control
As emissions standards for NOx, CO and other pollutants become increasingly stringent, it’s more
important than ever to partner with experts who have a full range of capabilities in both combustion
and post-combustion cleanup technologies. John Zink Hamworthy Combustion has been a pioneer
in emissions control for almost a century and has unmatched resources and expertise necessary to
push toward the goal of near-zero emissions with increased efficiency and lower operating costs.
Near-Zero Emissions. Low Operating Costs.
• Utility, field-erected and package boilers
• Gas-fired turbines / heat recovery steam generators
• Process furnaces
• Thermal oxidation systems
• Sulfur recovery systems
• Fired air heaters and dryers
APPLICATIONS
Extensive CFD modeling experience helps us ensure proper flow and temperature distribution, vital to post-combustion emission control such as SCR. This example shows CFD-based assessment of ammonia mixing downstream of an injection grid.
