World Leaders in Combustion Management Solutions http://www.autoflame.com/ Module EGA Trim Setup Introduction The Mk7 E.G.A Cell Status Further Information Settings EGA Trim Limits Introduction The Mk7 E.G.A Good Practice Troubleshooting Software Screenshots Combustion Management Systems Problems with O 2 trim 1. If only O 2 is measured and trimmed on then there is no measurement as to what the CO or NOx readings are 2.O 2 readings seem correct but what is actually happening? Changes in ambient conditions can cause the CO to rise significantly (>>100ppm) even though the O 2 reads well- O 2 trim does not correct Leaks through the boiler- small gaps in the boiler shell (around joints) can lead to increased air being induced into the boiler Higher O 2 readings from atmosphere so the system starts to trim, even though the combustion may be fine Combustion becomes unstable and dangerous CO levels (>>500ppm), higher NOx levels, O 2 readings correct Actual combustion O 2 readings around 0-0.5%- very dangerous!!
