The pros and cons of steam - NZ Energy Systems

Boilers aren't forced air heating systems which in turn means there's significantly lower operational noise. From when the steam leaves the boiler through pipes until it reaches a radiator there's no sound at all. This can prove useful in already loud businesses where noise is a constant factor.

Steam Sterilization | Disinfection & Sterilization ...

The oldest and most recognized agent for inactivation of microorganisms is heat. D-values (time to reduce the surviving population by 90% or 1 log 10) allow a direct comparison of the heat resistance of microorganisms.Because a D-value can be determined at various temperatures a subscript is used to designate the exposure temperature (i.e. D 121C).

Control Valve Characteristics | Spirax Sarco

In heat exchangers which use steam as the primary heating agent temperature control is achieved by varying the flow of steam through a two-port control valve to match the rate at which steam condenses on the heating surfaces. This varying steam flow varies the pressure (and hence temperature) of the steam in the heat exchanger and thus the ...
