Checking power plant components in a more targeted manner

11.06.2018

In future, conventional power plants based on coal and natural gas will have to work much more flexibly than was previously the case. One reason is that they work in close conjunction with power fed into the electricity grid from renewable energies, which means that the power plants run more often under partial load. This imposes greater stresses on the components and in a different manner than they were originally designed for. The new BINE-Projektinfo brochure entitled "Material loading in flexible power plants" presents a new concept for investigating and evaluating power plants with varying loads.

This enables operators and monitoring institutions to calculate the stability of components in terms of their damage more accurately and without compromising on safety.

Adjusting inspections to the actual load

Until now, conventional power plants were designed for full-load operation with constant pressure and temperature conditions. However, if in future it is intended that they should only produce the electricity requirement not covered by renewables, this will require a new, flexible mode of operation.

For all components, this means more part loads, more start-up and shut-down cycles, and more extreme and rapid temperature changes. Scientists have therefore studied the loads on thick-walled power plant components under cyclic temperature changes.

They have developed and tested a new method for conducting fracture mechanics-based analyses of the damage tolerance. The findings were also incorporated into a draft guideline for the fracture mechanics-based concept, which is currently in the validation phase.

The results are important for the business calculations made by power plant operators because the more frequent partial load operation causes not only higher maintenance costs but also reduced revenue from electricity sales than under full-load operation. TÜV Nord carried out the research project together with the University of Rostock and Research Centre Jülich.

Im Focus: The “TRiC” to folding actin

Proteins must be folded correctly to fulfill their molecular functions in cells. Molecular assistants called chaperones help proteins exploit their inbuilt folding potential and reach the correct three-dimensional structure. Researchers at the Max Planck Institute of Biochemistry (MPIB) have demonstrated that actin, the most abundant protein in higher developed cells, does not have the inbuilt potential to fold and instead requires special assistance to fold into its active state. The chaperone TRiC uses a previously undescribed mechanism to perform actin folding. The study was recently published in the journal Cell.

Actin is the most abundant protein in highly developed cells and has diverse functions in processes like cell stabilization, cell division and muscle...
