Monitoring and Instrumentation Capabilities

Data acquisition is critical to every burner and flare test performed at our International Research and Development Test Center. John Zink Hamworthy Combustion uses a myriad of technologies and equipment to measure emissions, opacity, temperature, pressure drop, heat flux and more.

John Zink Hamworthy Combustion’s world-class engineers and technicians use special software to remotely monitor and record burner data from test furnaces. The test data can be projected onto screens and monitors in the customer rooms for immediate analysis. For example, customers in the control room of the customer center can view live burner operation by video.

Our hard-bound test reports include the test procedures, pictures of the burner and furnace, the customer specified objectives and the test results, including emissions, temperature, flow rate, noise, relative air humidity, pressures and more.


Noise has become problematic to community and environmental councils around the world. Uncontrolled noise emissions in industrial environments can pose health hazards to employees exposed to high noise levels over extended periods of time, and can also be a source of discomfort to residents in the vicinity of the plant. Understanding the sources and spectrum of noise helps John Zink Hamworthy Combustion engineers develop fired equipment and accessories that control noise emissions.

John Zink Hamworthy Combustion employs some of the world’s leading experts (consultants and our own staff) in advanced acoustics, bringing “sound” experience and innovation to the John Zink Hamworthy Combustion team. Leading researchers in noise control, combustion instability and acoustic coupling work together to develop advanced noise-reduction techniques in combustion systems. Determining the fundamental characteristics of noise generation in combustion systems allows John Zink Hamworthy Combustion engineers to adjust fired equipment for ultimate noise control and combustion stability.

Test Analysis Monitors

John Zink Hamworthy Combustion measures burner emissions from the test furnaces in real time using dry and wet analyzers. The dry analyzers use water-cooled suction probes or quench-suction probes to pull gas from the stack. The sample is then conditioned, and analyzed for NOx, CO, O2 and unburned hydrocarbons.

Measuring the UV and IR radiations from the burner flame provides John Zink Hamworthy Combustion experts with more emissions data. John Zink Hamworthy Combustion uses NDIR to measure CO emissions, Chemiluminescent analyzers to measure NOx emissions and paramagnetic sensors to measure O2 concentrations.

Radiant effects can bias standard thermocouples by +/- 200 ˚F. That is why John Zink Hamworthy Combustion uses a suction pyrometer – the most accurate way to measure true flue gas temperature. The suction pyrometer minimizes heat loss or gain from radiant effects. Precision temperature measurement helps John Zink Hamworthy Combustion predict and guarantee NOx emissions from the burner.

Heat Flux
Uniform heat flux is essential to the ethylene cracking and crude oil refining industries. John Zink Hamworthy Combustion uses state-of-the-art heat flux probes to ensure uniform heat flux from the burner through the furnace walls and tubes. For maximum accuracy, the heat flux probes are regularly calibrated.

Instrumentation – CO, O2 and NOx

John Zink Hamworthy Combustion is meeting emission-regulation challenges with a new generation of emission control. From the moment a test is initiated, data is electronically recorded using John Zink Hamworthy Combustion’s state-of-the-art monitoring and control capabilities.

Our test furnaces are equipped with access ports to conduct extractive sampling for gas composition analysis across the height or length of the furnace. John Zink Hamworthy Combustion also uses the latest in continuous emission monitors (CEMs) to measure flue-gas emissions. Stack samples are continuously extracted at a high flow rate to minimize response time. A continuous slipstream goes to the sample conditioner to chill the sample below its dew point. Once the moisture is extracted, the CEMs measure NOx, CO and O2.

Our research and development furnaces, which contain many data-gathering probes and thermocouples, and provide extensive information regarding combustion and emissions.
