Gas steam boilers have no oxygen removal requirements

Module 106: Natural gas boiler flue gas recirculation

NOx is the collective term for oxides of nitrogen. Nitric oxide (NO), also known as nitrogen oxide and nitrogen monoxide, is a clear gas formed from nitrogen and oxygen at high temperatures. NO is the signalling factor that controls the body's vascular tone, and levels of

Boiler feedwater - Wikipedia

2019-7-15 · Boiler feedwater is an essential part of boiler operations. The feed water is put into the steam drum from a feed pump. In the steam drum the feed water is then turned into steam from the heat. After the steam is used it is then dumped to the main condenser. From the condenser it is then pumped to the deaerated feed tank. From this tank it
