HAROLD BECK & SONS INC. WELCOMES WILLIAM T. FEJES JR. AS NEW CEO
Harold Beck & Sons Inc., a leading manufacturer of reliable and high-performance electric actuators, is pleased to announce the appointment of William T. Fejes Jr. as its new chief executive officer, effective immediately.
Harold Beck & Sons Inc., a unique employee-owned manufacturer of industrial electric actuators headquartered in the Philadelphia area, is excited to unveil its new website.
Improved Combustion Control Leads to a Reduction in NOx Emissions
In March 1996, EPRI sponsored a demonstration project to showcase the potential for reducing NOx emissions by improving combustion control without the use of SOFA or Low-NOx burners. The project scope included the installation of Beck Drives on the windbox dampers, burner tilts, coal mill dampers, fan dampers and boiler feed pump fluid couplings. A Foxboro IA DCS and Rosemount sensors were also installed. TVA/EPRI is convinced that the accuracy and repeatability of the Beck drives has allowed them to maximize NOx reduction and improve boiler efficiency.
The Nucor facility in Flowood, MS was previously owned by the Birmingham Steel Corporation, and it was sold to Nucor Steel in November 2002. The site is a mini-mill that produces approximately 400,000 tons per year
of structural steel including flat, angle and rebar products. Major equipment in the mill includes one electric arc furnace (EAF), one multi-strand continuous caster, and one rolling mill with a Bricmont reheat furnace. PLC controls are used in all operating areas.
Prolonging Equipment Life in a WWTP can be accomplished by using More Reliable Actuators on the Ducking Skimmer Scum Troughs
In 2011, the City of Durham’s North Water Reclamation Facility (WRF) identified an opportunity to improve reliability and reduce maintenance costs associated with their ducking skimmer scum troughs by replacing the multi-rev electric actuators with Beck rotary actuators. Scum troughs remove sludge from the surface of the feed water and are integral to most primary, secondary and final clarifiers.
Actuator Resolution’s Impact on Steel Mill Furnace Combustion Valves
The ArcelorMittal – Galati mill was having trouble maintaining a reducing atmosphere in their continuous galvanizing preheat furnace. An oxygen starved environment within the furnace is created by maintaining
slightly fuel rich combustion at the burners. This limits oxidation of the steel sheet, improving quality as it’s heated prior to coating. Combustion air flow is monitored and, in a cascade control scheme, the gas valve is
adjusted to control CO to a level of 4 to 6%.
Precise control of fan fluid couplings is critical to boiler performance, and structural integrity. This pulp mill performed an evaluation of their Recovery Boiler FD & ID fan application to determine the cause of cyclical speed fluctuations.
