Boiler - an overview | ScienceDirect Topics

II.C.1.a Firetube boiler. The firetube boiler can be described in simple terms as a water-filled cylinder with tubes running through it which provide the escape path for the combustion gases or flue gas. As the flue gas passes through the tubes, the hot gases heat the tubes, which then heat the water to produce steam.

Steaming Rate Definitions - Clayton Industries Boiler and

Net steaming rate is the steaming rate at which a boiler produces steam to your plant or process. This makes it the most important steaming rate to consider. Net steaming rate differs from gross steaming rate in that it takes into account the amount of steam needed to heat the feedwater in the feedwater receiver (deaerator or hotwell).
