The Importance of Boiler Water and Steam Chemistry

1900s Large industrial steam boiler like in thermal power plant typically use water tube boilers as it can produce large steam flow rate (500 kg/s) and pressure up to 16 MPa (160 bar). [Ref22] Furthermore, water tube boilers can be installed in modern furnace that is …

Orders of magnitude (pressure) - Wikipedia

The division of megapascal pressure (MPa) determines whether a boiler is low and high pressure. Boilers that produce pressure above 80 MPa are considered to be high pressure. Low pressure boilers have a MPa below 80 MPa. Water circulation can be forced or natural. If the water is pumped, it is forced. If it is natural, it is by convection.

The maximum energy efficiency for the three curves occurs at a boiler pressure of 14 MPa. Therefore, this pressure can be considered a thermodynamic optimum for such a cycle under the design conditions. Exergy-efficiency profiles in Figure 12.2 b follow the same trend as energy-efficiency curves in Figure 12.2 a. Moreover, the pressure of 14 MPa appears to be the optimum pressure from an exergy perspective. …

Water Treatment Requirements for Low and Medium Pressure

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.

Pressure vessel - Wikipedia

For most dissolved solids found in boiler water, it is negligible by comparison to mechanical carryover at pressures less than 2000 psig (13.8 MPa). An exception is silica for which vaporous carryover can be substantial at lower pressures. Vaporous carryover depends on pressure and on boiler water chemistry. It is not affected by boiler design.
