Rapid growth and innovation in the past decade have enabled companies to implement key technologies to monitor, analyze, control and automate their assets. Wireless resistance temperature detectors, or wireless RTDs, have bridged the gap from decades of hardware to remotely connected devices.
A typical control approach for an industrial fired heater uses global measurements to keep the system efficient and within safe operating limits. Differences in combustion stoichiometry between individual burners, however, can cause global measurements to produce an incomplete picture of the combustion taking place within the heater.
Fluid-bed dryers offer an inherently efficient method of moisture removal that has not changed since the systems were developed in the 1950s. The introduction of ever-improving control technologies — personal computer-based and PLC control systems, smart sensors and other technological advances — in the last 40 years, however, has changed how process engineers operate their fluid-bed drying systems.
An ever-increasing need for steam at specific temperatures and pressures exists in many modern plants. Fortunately, significant improvements have been made to increase operational thermal efficiency and heat rates by the precise, coordinated control of the temperature, pressure and quality of this steam.
Some applications use a modular approach to temperature sensing while others must be built from scratch. Fortunately, there is no shortage of temperature sensor options to solve even the most complex problems.
Most people who purchase personal computers buy fully configured and assembled units. This is especially true for computer buyers who plan to use them for everyday tasks like word processing or surfing the web.
It’s a point of pride that I have every issue of Process Heating ever published cataloged in a small library in my home office. Admittedly, it’s not as tidy as you might find at your local library. I tend to stack issues that I “check out” on the floor in front of the library until it’s time to clean my office. And, while my lazy filing means a career as a bibliophilic cataloger is doubtful, it also provides opportunities for rediscovery.
Morris L. Crafton, founder of Thermcraft Inc., Winston-Salem, N.C., died in February at the age of 93. Crafton and his wife Clara founded the oven and furnace maker Thermacraft in 1971, initially focused on making replacement heating elements for industrial and laboratory furnace applications.
Epcon Industrial Systems was selected to build an industrial oven with two combustion chambers located on top and three guillotine doors. The large unit, which will cure airplane parts, was funded by the United States government with a comprehensive site factory acceptance test (FAT) and on-site commissioning.
A provider of stamping oil cleaning services utilized a thermal deoiler to eliminate toxic wastewater and reduce water consumption. The unit has a built-in secondary heat recovery system that uses a shell and tube heat exchanger design to recycle the heat from the oxidizer back into the burner-less oven.
An electrically heated catalytic oxidizer will be used by a Midwest medical products manufacturing company for the abatement of ethylene oxide (EtO) emissions. EtO, a volatile organic compound (VOC), is a flammable, colorless gas used as an agent to sterilize equipment and plastic devices that cannot be sterilized by steam.
BriskHeat, a provider of flexible heating, insulating, temperature-control and composite-curing solutions, opened a calibration center in Shenzhen, China. It joins the company’s ACR hot bonder calibration and repair centers in Columbus, Ohio, and AeroNed B.V. in Rotterdam Netherlands. These centers are manned by technical product specialists and sales engineers to provide field training and phone support.
Used in tandem, boiler feed and condensate return units can help ensure safe, reliable and efficient boiler operation.

In processes that require steam, the boiler is the heart of the operation, and if it fails, production can come to a grinding halt. So, if your industrial process uses steam, it is critical that the boiler and any of its auxiliary parts are in good working order, allowing the system to run most safely, effectively and efficiently.
A pulp-and-paper facility in the Pacific Northwest was forced to take down its large power boiler for repairs. The company called on Nationwide Boiler Inc. to provide two 70,000 lb/hr package watertube boilers on a fast-track emergency basis.
Hengyuan Refining Company Berhad chose the Rotork client-support program (CSP) for the asset management of Rotork valve actuation equipment at its Port Dickson refinery in Malaysia. The CSP encompasses 157 Rotork electric actuators, a Rotork master station and Pakscan control-loop testing facility.
An East Coast Brewery implemented a low pressure steam heating system and energy-efficient boiler to help increase its production.Cypress Brewing, Edison, N.J., wanted to go from a two-barrel system to a 20-barrel system. After a review, the three-year-old company installed low pressure steam, cast-iron boiler.
Lucifer Furnaces supplied several convection ovens to a manufacturer of small medical parts in the southern United States. The units, which heat to 1200°F, are insulated with 4.5" of multilayered firebrick and 2" insulating cold face block with overlapped seams for reduced thermal loss. Temperature uniformity is achieved with recirculating airflow.
Portable calibration baths are designed for on-site calibrations, allowing the technician to carry the bath to the location of hard-to-remove instruments. Models CLB30 and CLB31 units have cooling capabilities, allowing for calibration at temperatures as low as -31°F (-35°C). Models CLB50 and CLB51 provide heating for calibrations up to 437°F (225°C).
Offered as stationary and handheld models, VarioCAM HDx thermographic camera and the IRBIS 3 active thermography software can be paired with a trigger unit and connection cables to create a lock-in thermography station.
Digital mass-flow controllers provide stable control of mass-flow rates of process gases. With simultaneous display of mass-flow, volumetric-flow, pressure and temperature parameters, it can be used with manufacturing, bioreactors and surface depositions, and gas-sampling activities.
Model HTZ simultaneously measures humidity and temperature in industrial manufacturing applications. Based on the humidity and temperature values, the Smart HART transmitter also provides a dewpoint measurement as a calculated variable.
Suited for applications that require clean, dry parts such as brazing, coating, soldering and plating, thermal deoilers use indirectly heated dry air to clean parts contaminated with oils or lubricants.
Nicholson industrial steam traps are suited for condensate systems, main steam systems, process control and process heating. The product line includes mechanical, orifice, thermostatic, thermodynamic and clean steam designs.
