  • Boiler Economizer Tube Failure - CR4 Discussion Thread

    2013/8/1 · In reply to #6. Re: Boiler Economizer Tube Failure. 05/31/2013 7:11 AM. When we analyze flue gas the oxygen in flue gas is 3 to 5 % when boiler is running on furnace oil and SO2 is below 800 ppm. When boiler is running on natural gas the oxygen in flue gas is 2 to 3 % . These are results of Oxygen not air.Get Price
