Boiler Uptake Fire and Exhaust Gas Economiser Fire

Aug 27, 2015· Auxiliary boiler uptake or flue gases normally pass through economisers or air pre-heaters or feed water heaters. All these types of heat exchangers are fin type. Hence large amount of carbon or soot deposits on the fins. Along with the flue gases some un-burnt carbon particles also get deposited on the economisers.

Boiler Combustion | CleanBoiler.org

Boiler Combustion. In industrial boilers, NOx is primarily formed in two ways; thermal NOx and fuel NOx: Thermal NOx is formed when nitrogen and oxygen in the combustion air combine with one another at the high temperatures in a flame. Thermal NOx makes up the majority of NOx formed during the combustion of gases and light oils.

Is a high efficiency, condensing gas boiler the best

Aug 13, 2018· At this point, flue gas temperatures drop and as the flue gas cools, condensate forms in the heat exchanger. Condensing boilers cool the exhaust gas so much that they can be vented with CPVC or Polypropylene (plastic) pipe, instead of the steel venting required by conventional boilers.
