BOILERS | Energy-Models.com

2.1 Introduction. A boiler is an enclosed vessel that provides a means for combustion heat to be transferred into water until it becomes heated water or steam. The hot water or steam under pressure is then usable for transferring the heat to a process. Water is a useful and cheap medium for transferring heat to a process.

Our Boiler Feedwater Pumps Just Do Not Perform Like …

1/4/2012 · Plant steam pressure was 215-225 psig and feedwater pressure was normally 320 to 340 psig with one pump in service. Each pump was rated for 290 gpm at 720 feet of head. The deaerator was being operated at 7 psig (233 °F); however, it was installed on the roof of the boiler building with a pump suction elevation head of 45 feet.

The types of industrial steam boiler | Feedwater Article

i) Coil Boiler. The basic design is for feedwater to be pumped to single or multiple coils arranged around a burner. The heat input and fluid flow produce steam at the coil exit of between 10-20% wetness. This steam can then be passed through a separator and superheater if required. The coil arrangement can include an economiser section in the
