27 Jun Temperature Is King When Using Steam
Pressure is a byproduct No mysticism here just simple basic science
Temperature and the Pressure of the saturated steam are mutually dependent. When one of them is given, the other is determined.
For example, if a steam cleaner produces 58 psi of pressure then the boiler will maintain an average 293°F (not up to 320°F as many insist on advertising). Simple science, but it appears to be quite difficult for many sellers to get this straight. However, facts are facts and it is important be provided true information when making an investment in a steam cleaner or any investment. Is that not what one expects?
The saturated steam table is a good reference. As one can see, there are 3 basic columns, pressure shown in the American measure of psi, bars (the European equivalent) and the matching temperature created under pressure.
When shopping for a steam cleaner let us make it simple, the lower the pressure the wetter the steam and the lower the efficiency. The temperature creeps up, so does the pressure in the boiler. You cannot change the table therefore if you are shopping for a steam cleaner and the pressure is 50 psi, the temperature will simply be an average of 281. If there is a discrepancy, then the advertising is incorrect and you are not getting what you pay for or paying more for less.
|Pounds Per Sq. Inch /Pressure||Bar (European measure)||= Internal Boiler Temp|
|50 PSI||3.5||281 F.|
|58 PSI||4||293 F.|
|65 PSI||4.5||298 F.|
|72 PSI||5||311 F.|
