Thirty years ago, heat transfer fluid (HTF) manufacturers would sell virgin fluids at inflated prices and dispose of the used thermal fluids without regard for the potential of remediating the used fluid. Times have changed.
A comprehensive solution for industrial combustion safety helps plant owners and operators improve safety and reliability while reducing risk and optimizing the efficiency of fuel-fired equipment used in process heating operations.
The importance of safety in industrial ovens, furnaces and other combustion systems cannot be overstated. Hundreds of combustion-related incidents and near misses occur every year, resulting in millions of dollars in business interruption, facility damage, lawsuits, fines, litigation and lost marketshare.
When the 2011 edition of the industrial ovens safety standard NFPA 86 was released, for the first time, safety programmable logic controllers (PLCs) were recognized as logic devices suitable for the safe operation of industrial heating equipment. The safety PLC could now perform the control logic, but it still could not directly control the combustion safeguard systems.
Most modern thermal fluid heaters at industrial plants are reliable, so unexplained heater shutdowns do not happen often. As a result, many plant operators do not know how to fix a shutdown problem — they have never encountered one in the past. But, eventually one does occur, and it is usually at the most inopportune time. This means the operator is under pressure to get the heater back in operation.
It is essential that heat transfer systems for chemical processes are designed to maximize efficiency. Because the heat transfer step in many chemical processes is energy intensive, a failure to focus on efficiency can drive up costs unnecessarily.
The transfer of heat from one fluid to another is an essential component of all chemical processes. Whether it is to cool down a chemical after it has been formed during an exothermic reaction, or to heat components before starting a reaction to make a final product, the thermal processing operation is core to the chemical process.
In the ever-evolving consumer economy, new technology is regularly transforming communication between buyers, sellers and manufacturers. In the consumer marketplace, buyers have unprecedented access to nearly any product imaginable.
I would like to say first, to our readers, advertisers, contributors and partners, THANK YOU! As the new group publisher for the Thermal Processing Group at BNP Media, I’m looking forward to continuing to build on our long-standing brands.
Miura Boiler, Rockmart, Ga., launched a quick ship program. According to the company, customers can receive new boilers in as few as a few days. In some cases, says Miura, companies opt for a new boiler rather than seeking a temporary solution via a rental boiler.
As part of an expansion plan, the sensor technology business of Heraeus will operate under a new name. Heraeus Nexensos platinum temperature sensors can be used to measure and regulate thermal processes up to 1922°F (1050°C).
The probable cause of an explosion and fire was a failure of the brazed aluminum heat exchanger (BAHX) due to thermal fatigue, says the U.S. Chemical Safety Board. The CSB has released its final report of the June 27, 2016, investigation of the explosion and fire at the Enterprise Products Pascagoula Gas Plant in Pascagoula, Miss.
Two Class A cabinet ovens with a maximum temperature rating of 180°F (82°C) have been shipped to the specialty filter industry. The Gruenberg industrial ovens are constructed from a structural-steel frame that supports the stainless-steel interior chamber lining and the exterior sheet metal. All interconnecting struts are non-continuous, which helps keep the exterior cool.
A vacuum-purging, semi-continuous controlled-atmosphere brazing (CAB) furnace was delivered to a North American automotive aftermarket manufacturer. Seco/Warwick, which supplied the unit, says it is the first of its kind.
A tissue production machine will be installed at Papel San Francisco’s mill in Mexicali, Mexico. Startup of the Valmet-supplied line, which will fulfill the company’s need of new capacity for standard tissue products, is scheduled for the third quarter of 2020.
An augmented reality platform from Baker Furnace allows operators, maintenance personnel and engineers to interact with an industrial furnace through a tablet. Three levels of access via a PLC — augmented operator, augmented maintenance and augmented engineering — provide step-by-step procedures, component manuals, mechanical drawings, electrical drawings and live data at the component level.
A custom 200°F (93°C) steam-heated cabinet oven designed and built by Lewco Inc. is being used to melt residuals out of special containers. A stainless steel collection pan is included in the base of the oven. The pan collects the contents melted from the containers and compiles them in a drain pipe that extends out from the bottom of the oven. The contents are then emptied into another container.
Kromschröder BCU 4 Series is a multi-functional, modular control solution designed for directly ignited or pilot/main burners of unlimited capacity in intermittent or continuous operation, and for modulated or step-controlled gas burners.
Rotork IQ includes a bespoke plug-and-socket electrical connection as an option. The plug-and-socket interface provides a fast connect/disconnect for multi-turn and part-turn actuators, encompassing three-phase, single-phase and DC electrical variants and including many actuators with explosionproof EXd enclosures conforming to ATEX, IECEx, CSA and CSAus international standards.
Two standard variations of ceramic insulation for box furnaces are rigid ceramic fiber boards and flexible blankets. They are manufactured using strands of refractory silicate compressed or woven into a lightweight textile, with excellent inherent strength and low thermal conductivity.
With a firing range of 15,000 to 200,000 MBH, Model FDR(X) combines a windbox, air register, ignition assembly, fuel train, flame-safety control, combustion control, flue-gas recirculation system and forced-draft blower into a packaged unit.
RotaBed fluidized bed scrubber is designed to handle gas capacities from 500 through 250,000 acfm. A swirl-induced Coriolis grid achieves good fluidized-bed stability, resulting in efficient gas mixing and transfer efficiency.
Electrically heated, 500°F (260°C) cleanroom oven has two chambers, each 34 x 54 x 72”. A 10,000-cfm, 7.5-hp recirculating blower provides horizontal airflow to a common central duct system while 80 KW are installed in Incoloy-sheathed tubular elements.
