Should South Africa prioritize domestic manufacturing to improve the efficiency of national power infrastructure?
Steinmüller Africa has successfully delivered a locally manufactured header-type HP heater to a power station. The unit is designed to use turbine steam to preheat boiler feedwater and improve overall plant efficiency.
Why it matters
The component enhances power plant performance by reducing thermal stress on boiler pressure parts and decreasing boiler tube leaks. This increase in thermal efficiency also allows for reduced coal firing and lower flue gas emissions.
The project spanned a total of 6 years from initial concept to final delivery. The production process integrates 3D modelling, computational fluid dynamics, and Kanban-based assembly methods.
The players
Steinmüller Africa
An engineering and manufacturing firm based in Pretoria that specializes in components for the power generation sector.
The details
Engineers at the Pretoria workshop replaced traditional submerged arc welding with friction welding for nipple-to-header joints to improve structural integrity. The use of 3D modelling and computational fluid dynamics during development ensures the unit meets precise operational demands.
