How Do Steam Boilers Work - What Do Steam Boilers Do?

A steam boiler is a type of heat exchange system where water is heated to its’ boiling point via combustion of a fuel blown through a tube submerged in water. The heat produced in this system is then rejected into the system as steam. This steam flows through pipe systems to the equipment that is being heated, whether it be hot water coils in air handling units, or other water heating equipment.

Thermal power station - Wikipedia

For a typical late 20th-century power station, superheated steam from the boiler is delivered through 14–16-inch (360–410 mm) diameter piping at 2,400 psi (17 MPa; 160 atm) and 1,000 °F (540 °C) to the high-pressure turbine, where it falls in pressure to 600 psi (4.1 MPa; 41 atm) and to 600 °F (320 °C) in temperature through the stage. It exits via 24–26-inch (610–660 mm) diameter cold reheat lines and …

Pressure Gauges and Switches - Omega Engineering

Pressure gauges and switches are among the most often used instruments in a plant. But because of their great numbers, attention to maintenance--and reliability--can be compromised. As a consequence, it is not uncommon in older plants to see many gauges and switches out of service. This is unfortunate because, if a plant is operated with a failed pressure switch, the safety of the plant may be …

Make-up water for steam boiler — Heating Help: The Wall

Why is cold water used for make-up water on a steam boiler? Why not hot water? I would think hot water would be better because a lot of the soilds have already dropped out of it in the water heater meaning less sludge in the boiler. 0 · Share on Google+.

06-10-2008 · Without expansion room, there will be no steam. The pressure will build up, but the water will not turn to steam. This results because the partial pressure of the heated water does not exceed the partial pressure of the surrounding volume, a necessary condition for steam is that its pressure exceed the surrounding environment outside the water.

why return condensate to the boiler operation

Why Return Condensate to the Boiler Operation

 · PDF file

If condensate is not returned to the boiler plant, the steam system has to make-up the loss with cold, untreated, raw water that has to be prepared for the boiler operation. The preparation of the make-up water has a preparation cost. The make-up water is also going to contain substantially lower BTU content that has to be raised in the deaerator or atmospheric feed water heater. This energy addition …
