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.
