Boiler Combustion

Low nitrogen oils can contain up to 15-20 times less fuel-bound nitrogen than standard No. 2 oil (less than 0.001% fuel-bound nitrogen). When low NOx oil is fired in firetube boilers utilizing flue gas recirculation, NOx reductions of 60%-70% over NOx emissions from standard No. 2 oils have been achieved.

Boiler Feedwater Treatment (Part I): Why Water Treatment

Boiler feedwater. Boiler ‘feedwater’ is the water supplied to the boiler. Often, steam is condensed and returned to the boiler as part of the feedwater. The water needed to supplement the returned condensate is termed ‘make-up water’. Make-up water is usually filtered and treated before use.

Boiler Efficiency and Combustion

The boiler pressure is maintained at the top of its control band, and the level of stored energy is at its greatest. Should more energy be required at short notice, the control system can immediately respond by increasing the firing rate, without pausing for a purge cycle.
