Thanks rmw for your valuable suggestions It`s a 80 t/hr 3200 k Pa 450 deg C bagasse fired boiler. One strange thing I`m noting, may be it`s not anornal, is that the O2 measured at the boiler gas outlet, that is before preheating the cold air, is around 1 % and the O2 measured just before the economiser is 3 %.One obvious reason might be that it is sucking air in between, but it is not visible.
