Check out the November 2019 edition of Process Heating: Installing heat tracing, IIoT, boilers, reducing cross contamination in pharmaceutical applications, optimizing your steam-injection heating application and much more!
The use of optical fiber for temperature sensing is expanding beyond safety applications. Optical sensors are replacing spot sampling in implementations that require accurate heat measurement and control.
Boiler water treatment is critical to ensuring your boiler is operating as efficiently as possible, and no proper water treatment program is complete without a thorough understanding of the feedwater setup. A crucial step in preparing the feedwater for the boiler is preheating and deaerating the water in a separate vessel directly upstream of the boiler.
Feedwater tanks are heated storage tanks that do not have a specific deaerating section and operate at atmospheric pressure. In addition to being a feedwater reservoir, these tanks also act as condensate receivers, cold-water makeup locations and as a point for chemical injection.
Cross contamination in the pharmaceutical industry is not just an issue for those working in it, but for the wider public as a whole. As general awareness of the potential issues has increased, more questions are being asked of manufacturers and health professionals about the safety, integrity and potential side effects of a range of products and medicines.
Many companies have a need for the heating of fluids in their facilities. These can include heating of fluids to improve chemical reaction, slurries for production needs, wastewater processing, hot water for equipment washdown and parts cleaning, and many other fluid-heating requirements.
One of my favorite things to do near the end of the year is review the most popular content on our site — in the last year and overall. It helps me recognize topics that may warrant more coverage, and it can prompt me to revisit still-popular topics I may have missed in 2019.
Gasbarre, Plymouth, Mich., hired Tom Spicer as a field service technician for Gasbarre Industrial Furnace Systems, the OEM of J.L. Becker brand equipment. Spicer has more than 20 years’ experience with field service for industrial thermal processing.
Gasbarre Thermal Processing Systems commissioned a 48” belt annealing furnace for a global manufacturer. The furnace is equipped with three heating zones that can heat up to 1200°F (650°C). The company required a target belt speed of 10 in/in and 2,000 lb/hr, which were achieved.
A control system has been developed for use on composite curing ovens. Wisconsin Oven’s Premium Control system provides data acquisition and is intended for applications where process control is critical.
Sandvik’s team based in Dubai will partner with Serck Services of United Arab Emirates to manufacture heat exchangers. Duplex tube-to-tube sheet welding is key to fabrication, and Sandvik will offer this support as part of the agreement.
A $12 million contract to refurbish a recovery boiler for a U.S. manufacturing facility was awarded to Babcock & Wilcox. B&W’s scope includes the design and manufacture of a steam drum, furnace, superheater, generating bank, air system, economizer and other components.
A cleanroom oven will be used for final cure of hard-coated optical lenses. Designed and shipped by Grieve Corp., the 350°F (177°C) electric oven has 60 kW installed in Incoloy-sheathed tubular heating elements.
Superior Boiler received a contract for a major boiler-room expansion at Dalhousie University in Halifax, Nova Scotia. The Hutchinson, Kan.-based company will supply two watertube boilers with a square furnace. Each boiler is designed to deliver up to 85,000 lb/hr of steam capability.
Dover Precision Components, a provider of performance-critical solutions for rotating and reciprocating machinery, broke ground on a new laboratory. Dubbed the “Innovation Lab, the nearly 12,000 ft2 building is being built north of the company’s Pearland operations in Houston, Texas. It is scheduled for completion in the second quarter of 2020.
United Process Controls upgraded the vacuum furnace controls and automation platform for Woodward Inc., a Fort Collins, Colo.-based provider of fuel and control systems for aircraft engines. The new controls will be used to provide streamlined reporting for Nadcap compliance and integrate with the company’s enterprise-planning system.
The horizontal, conveyorized gas-fired and electrically heated convection drying and curing systems are intended for applications to dry off water or cure liquid and powder coatings on products processed horizontally.
The metal-housed heating mantles have built-in temperature controllers and magnetic stirrers. The magnetic stirred heating mantles are designed to uniformly heat round-bottom flasks while stirring the contents.
The 500°F (260°C) gas-fired oven is supplied with a shelf truck and equipped with shelf supports on 3.5” centers. A modulating natural gas burner provides 175,000 BTU/hr, and a 2,000-cfm, 2-hp recirculating blower motor provides horizontal airflow from a top-mounted heat chamber.
