|Laser Based O2 and CO Monitoring Project|
|$250,000 funding for ‘Laser based O2 and CO monitoring'; submitted by HRL Technology Pty Ltd with support from EnergyAustralia, Siemens Ltd, AGL Loy Yang Pty Ltd, GDF SUEZ Australian Energy (Hazelwood), Macquarie Generation, Intergen - MOC, Origin Eraring, CS Energy, Alinta Energy and a number of other Australian power industry participants.|
|The performance of existing coal-fired power stations can be improved to reduce the coal utilisation and therefore CO2 gases emitted.|
Continuous measurement of the composition of the flue gases allows on-line modification of the plant boiler and fan operation to optimise coal combustion. However, power station boiler ducts present a very hostile environment for sensors and, consequently, current-generation sensor technologies have proven to be unreliable for process control.
This research project will test state-of-the-art tuneable laser sensors to measure oxygen (O2) and carbon monoxide (CO) in brown coal-fired power station flue gases.
Project trials will determine whether Tuneable Laser Diode Spectroscopy (TLDS) instrumentation, utilised successfully in the oil and gas industry, can provide a more accurate representation of oxygen and CO concentrations in station boiler economiser outlets.
Current CO measurement technologies in Australian coal-fired power stations are compromised by high levels of dust, moisture and the sheer size of the boiler ducts. Inaccurate readings of oxygen content within the boiler ducts can result in increased coal usage to generate the same amount of energy.
This research project is targeting improved CO measurement in order to optimise the combustion of both brown and black coals; thereby reducing coal fuel demand and boiler draft fan power consumption.
|This is the first trial of this technology in Australia and a successful outcome could lead to tuneable laser instrumentation being widely adopted in brown and black coal-fired power stations throughout the country. |
Improved plant efficiency will simultaneously reduce CO2 emissions produced in the boiler and achieve plant operational savings such as lower fuel and CO2 penalty costs and reduced auxiliary load.
