for a coal-fired power station. Due to the coal composition, the specially required flow conveyance and the very high temperatures, our customer had specified silicon carbide as the wear protection material. After we had calculated the costs of the material and the production, the responsible project managers at ALSTOM almost had a heart attack. The costs were very far over the planned budget and the delivery time for the custom-made silicon carbide elements was almost three times as long as ALSTOM had planned.
We then offered ALSTOM a lining with a silicon carbide UHPC wear-resistant concrete as an alternative. The material costs were reduced by more than 50% and the delivery time of the elements manufactured by us was reduced by more than 70% compared to the elements made of silicon carbide ceramics. As we had already supplied many UHPC linings for ALSTOM over the past decades, the project managers had complete confidence in our proposed solution.
The production of the burner elements was carried out according to our time schedule and the elements
have fulfilled their purpose until today.
In the meantime, other burner suppliers for coal-fired power plants have also successfully used this solution worldwide.
