PDF APPLICATION GUIDE - Slantfin

Process applications that use fresh water require the use of heat exchangers. Any process application that results in intro-duction of fresh water into a boiler can cause scaling, with deposits forming in the boiler and surrounding piping. This will damage the boiler. Introduction of fresh water from leaks will cause similar damage.

Water Treatment (Steam Boilers) | CleanBoiler.org

Water quality is primarily an issue with steam boilers that use a lot of make-up water. Closed-system hot water boilers are the least effected by water quality because they use the least amount of make-up water and operate at lower temperatures. The common minerals in water that lead to scaling problems are iron, calcium, magnesium and silica.

What is Boiler and Condenser Pressure - Rankine Cycle

Decreasing the turbine exhaust pressure increases the net work per cycle but also decreses the vapor quality of outlet steam. The case of the decrease in the average temperature at which energy is rejected, requires a decrease in the pressure inside condenser (i.e. the decrease in the saturation temperature).The lowest feasible condenser pressure is the saturation pressure corresponding to the
