Coal-mill optimisation in coal-fired power stations aids flexibility

Many of the existing pulverised coal-fired (PCF) power stations are operated at a fixed steady load (i.e. baseload operation). There is however a growing requirement for load following or flexible operation, which requires flexibility in most of the components of the power station. Flexibility and efficiency can be improved by close control of the coal […]

How modern gas turbines achieve excellent environmental performance at high load

This article explains how the gas turbines used at the Dedisa and Avon peaking power plants – which were highlighted in the June 2016 edition of Energize (“Privately owned peaking power station nears completion”) – achieve their environmental performance with lower NOx emissions even when operating at peak load. Dedisa and Avon peaking power stations […]
