Polymer valves

Groth Corp. announces a new line of relief valves designed for environments too corrosive for metallic or fiberglass valves. Constructed of non-metallic, corrosion resistant materials, these valves will operate in highly caustic environments not suitable for metal and fiberglass. The all-polymer internal construction enables these valves to operate in the harshest chemicals making them ideal for use with chlorine, ethylene dichloride, hydrochloric acid and other corrosive materials.

Polymer valves operate in a similar fashion to their metal and fiberglass counterparts. They protect low-pressure atmospheric storage tanks from excessive pressure and/or vacuum and limit fugitive emissions by preventing constant tank “breathing” to atmosphere. The non-metallic pressure and/or vacuum relief valve is available in vent to atmosphere or pipe-away configurations.

Oil-Glo dye

Maintenance specialists rely on fluorescent leak detection to pinpoint leaks in all types of industrial equipment, including milling and injection-molding machines, hydraulic tanks, fork lifts, gear boxes, punch presses and other equipment that use hydraulic fluids. Just add a small amount of Spectroline OIL-GLO 22 dye to a hydraulic system and allow it to circulate for several minutes. Wherever there is a leak, the dye escapes with the oil and accumulates at the site of each and every leak. Then scan the system with a high-intensity Spectroline ultraviolet or UV/blue light lamp and the dye glows a bright yellow color to clearly reveal the exact location of leaks.

Blasch ceramics

Tubular air heaters, or air preheaters, are used in a variety of processes to capture heat from combustion and use it to preheat air coming into the boiler or furnace. Plant operators often find serious damage within the first few inches of tubing. This requires immediate attention and many times it is not foreseen, adding substantial cost and time to the outage.

The Blasch Precision Ceramics air heater insert is designed to protect the end of the tube and the first 8”-10” of the tube ID. These inserts have a range of applications including waste coal, rice husks, sugar cane, pulp and paper, and agricultural waste. Blasch inserts may be manufactured with round flanges, to cover just the tube end, or square, to cover the entire tubesheet between the tubes.

Ash extractor

United Conveyor Corp. unveiled the VAX Vibratory Ash Extractor for dry bottom ash handling. Designed to improve operational efficiencies at utility facilities, the VAX is suitable for pulverized bituminous and sub-bituminous coal boilers, and can be retrofitted for lignite fired boilers.

The VAX Vibratory Ash Extractor incorporates a vibratory conveyor trough that can resist large slag falls and absorb clinker impact, reducing stress to the bin capturing the bottom ash. Coil springs absorb impact and transmit the vibrating motion to the steel pan, eliminating the need for tensioning devices or secondary conveyors to remove fine particles. Unlike wet designs that require rollers and belts, and secondary conveyors, the VAX is designed with no exposed moving parts in the boiler flue gas environment to minimize forced boiler outages and improve boiler efficiency.

Airpot introduces the first three in series of online technical product videos, which illustrate pneumatic control of unwanted motion using Airpot dashpots, snubbers and air-bearing actuators. Dynamic systems often produce unwanted motion and the need for control of velocity, time delay, falling mass, vibration, oscillation, over action and impact. Airpot’s glass cylinder and graphite piston technology controls motion by pneumatic damping, actuating with air or vacuum, applying a precise force, for pumping or pulsing air, and to sense, indicate or relieve pressure.

New Transporters Improve NUHOMS-type ISFSI Installations

Wheelift Systems, a Doerfer company, has developed technology that improves the safety and efficiency of spent fuel cask transfer to independent spent fuel storage installation (ISFSI) facilities where the NUHOMS horizontal storage modules are used. (NUHOMS is the registered trademark of TransNuclear Inc.)

According to Mel Terry, Wheelift Systems Group senior systems application specialist, Constellation Energy will be one of the first in the industry to adopt the new ISFISI cask transporting method.

With Wheelift’s new self-propelled modular transporter (SPMT), the heavy load transporters can operate in severely confined spaces on any kind of floor surface.

The SPMT has an all-directional steer, fluid-equalizing suspension that makes it possible to have narrower aisles between rows of horizontal storage modules.

The specialized computer-controlled axle assemblies can rotate on-center while under full load. During alignment, all-directional corrections of less than +/- 1/16th on-the-inch are the norm.

Multi-axle SPMTs produced by European manufacturers like Scheuerle and Goldhofer have been used in the nuclear industry for years to move reactor vessel loads that often weigh more than a thousand tons. Wheelift’s miniaturized in-plant version is considerably smaller but has the same or greater load capacity as the European SPMTs.

An onboard diesel-driven generator supplies electric power for the transporter and serves the transfer cask ram’s built-in hydraulic power unit.

To enhance operation during fuel loading and during precision alignment at the ISFSI, the engine can be shut down and a shore power extension cord plugged in for near-silent operation.
