Duct burners operate in some of the most extreme environments, enduring hurricane-force winds and blistering temperatures round-the-clock. Inadequate or improperly engineered equipment often leads to issues such as failing or fractured on burners.
CFD analysis resolved a major performance issue at a natural gas plant. By identifying and correcting bypass flow in the HRSG, optimal steam and power output were restored. This showcases the effectiveness of CFD in solving complex industrial problems.
Grade 91 is a CSEF (creep strength enhanced ferritic) alloy introduced in the late 20th century for high temperature service in power boilers. ASME BPVC-II develops material properties based on time-to-rupture data after 100,000 hrs, with a safety factor of 3.5.
Tetra Engineering is excited to once again participate in the upcoming 501F Users Group Conference! Come visit our booth our engineers will be set up and ready to discuss our services for HRSGs, High Energy Piping, Cold Weather Readiness & Digital Transformation.
HRSGs and power boilers are built by assembling large numbers of components, mostly by welding. Design choices in optimizing heat transfer against overall cost lead to configurations that aim to minimize the number of welds per square meter of heat transfer surface. In addition, fabrication of the modules is frequently subcontracted by the OEM for manufacture in regions where manpower is cheaper. The OEM becomes in effect an integrator of components built by others. How can Product Quality for pressure parts be assured in that context?
Tetra Engineering is presenting two papers at the 2020 ASME POWER Conferencewhich was scheduled to take place at the Disneyland Hotel in Anaheim, California August 3-6 but will now be a virtual conference online this year. The second paper has been written in collaboration with our partners atTG Advisers, Inc.
Two of the most common issues that power plant owners and operators face in the HP Evaporator section areUnder-deposit Corrosion (UDC) andCorrosion-Fatigue. In this short article we will cover UDC and what key actions should be taken to predict and prevent costly forced outages.
