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 […]

Testing the acoustical noise of a generator set and interpreting the data

A growing number of businesses find that large, heavy-duty generator sets are critically important to their operations, whether for continuous, prime or standby power. Not surprisingly, large generator sets produce high levels of noise that often must be mitigated to meet local, state and federal regulations or directives. This usually involves key decisions about the […]

How nuclear can support green applications for a sustainable SA

We often hear about next generation nuclear power plants under development and construction worldwide. These nuclear power plants are designed from the ground up utilising different philosophies and more importantly, different objectives than conventional light water reactors widely in operation today. Fig. 1 illustrates how nuclear power plant designs have evolved since the late 1940s up […]
