Figure 3.1 Steam Phase Diagram For a boiler is operating at a pressure of 8 kg/cm2, steam saturation temperature is 170 oC, and steam enthalpy or total heat of dry saturated steam is given by: h f +h fg = 171.35 +489.46 = 660.81 kCal/kg. If the same steam contains 4% moisture, the total heat of steam is given by: 171.35+ 0.96 x 489.46 = 641.23 Learn More
Boiler - Fundamentals Steam production and steam uses Steam purity and steam quality Steam Production When heat is added to water, its temperature rises at a rate of 0.56°C (1°F) for each heat input of 2.095 kJ/kg (1 Btu/lb) If we take water at 0°C (32°F) and we add 419 kJ/kg (180 Btu/lb) then we 4 151.96 640.70 2108.10 2748.80 0.374Learn More
mill has a boiler producing saturated steam at, say, 250 psi and you are using steam at your dry kilns at 100 psi (which has been reduced from 250 psi through a pressure reducing valve), the steam will be 407°F, not at the saturation temperature of 338°F for 100 psi steam. The steam retains its original temperature of 407°F,Learn More
steam system, (3) improving boiler operations, (4) improving resource utilization in the steam system, and (5) investigating energy losses in the steam distribution system. The guide discusses major areas where steam systems can be improved and outlines calculations that can be per-formed to quantify steam system improvement opportunities. 1.Learn More
