Get A QuoteGauge pressure is pressure in pounds per square inch above atmo-spheric pressure which is 14.7 pounds per square inch absolute. Gauge pressure (psig) plus 14.7 equals absolute pressure. Or, absolute pressure minus 14.7 equals gauge pressure. Pressure/Temperature Relationship (Columns 1, 2 and 3). For every pressure of pure steam there is a

Sizing a Boiler Feed Pump Receiver. The receiver tank should be able to hold five minutes worth of condensate for boilers up to 200 BHP and 10 minutes of condensate for boilers over 200 BHP.

Get A QuoteThe boiler evaporates 3200 kg of water at 44.5 o C into superheated steam at a pressure of 12 bar and 274.5 o C. If the calorific value of the fuel is 32760 kJ/kg, determine (a) equivalent evaporation "from and at 100 o C"; (b) the thermal efficiency of the boiler.

Get A QuoteAs in the previous example (2.3.4), the specific enthalpy of dry saturated steam (hg) at 1 bar g is 2 706.7 kJ/kg. The actual total enthalpy of the steam is greater than the total enthalpy (hg) of dry saturated steam at 1 bar g. The steam is therefore not only dry, but also has some degree of superheat.

Get A QuoteI suspect that every industry has its own criteria for steam systems, and I am only familiar with systems in an oil refinery. At the plant where I spent the first fifteen years of my career, we had the following steam systems (all expressed in PSI

Get A QuoteBoiler feed water quality is limited owing to problems of (1) scaling, (2) corrosion, and (3) foaming. In order to avoid these problems, the quality guidelines shown in Table IV have been adopted. Data in Table IV show a major difference between cooling water and boiler feed water quality constraints, in that boiler feed water has a strong relationship between water quality and the pressure of

Get A Quote140 th 65 bar pressure high pressure boiler Our oil/gas fired boilers can be divided into SZS water tube boilers and WNS fire tube boilers depending on the medium inside the tubes. With multiple pressure designs, the water tube boilers can meet the steam supply requirements of 2.5MPa or above.

Get A QuoteSteam, Boiler, and Blowdown Pressure are the same. Combustion Efficiency is the % of fuel energy that is directly added to the feedwater and not otherwise lost or used. Blowdown Rate is the % of incoming feedwater mass flow rate that leaves the boiler as a saturated liquid at boiler pressure.
