ABB launches guide to combustion optimisation 12 September 2012

ABB Measurement Products has published a beginner's guide to combustion, providing a step-by-step process to achieve optimum combustion efficiency for any plant.

The guide makes the point that poor control of the combustion process can lead to plant damage as well as soot formation and flue duct corrosion.

Available free, it covers the key parameters that affect combustion performance, including: fuel flow rate, moisture content and composition; temperature; and pressure.

It explains the importance of oxygen measurement in combustion and how this can be used to optimise the air/fuel ratio to reduce harmful emissions and improve efficiency.

The guide also highlights how the latest generation of MCERTified Zirconia oxygen sensors (ATEX/ IECEx) can be deployed to measure oxygen concentration, together with the advantages of using in-situ analysers over portable devices.

Potential pitfalls such as partial pressure effects and errors caused by combustibles in flue gases are also explained, with calculation examples and simplified equations.

Copies of the guide are available by emailing moreinstrumentation@gb.abb.com or phoning 0870 600 6122.
