Propane is fed to the burner where it is lit by a spark plug. Fuel oil is then fed to the burner and is burned by the propane flame. Once a stable flame is established the coal/air mix is blown through the burner where it lights spontaneously. The propane and oil are then shut off. In 2003, we completed the replacement of all the original burners with low NOX burners to reduce the amount
of oxides of nitrogen produced.
The propane burners are used to start the boiler up, a bit like firelighters. At full output the power station can burn around 36,000 tonnes of coal a day – that’s a lot of powder!”
