steam and vapor reduction

Depending on the amount of condensate being recovered and reused, other benefits may include a reduced need for boiler blowdown through better feedwater quality, and less corrosion in the system as water quality becomes more consistent throughout the grid.
Superheated steam is not usually used in a heat cfj résultats concours exchanger due to low heat transfer co-efficient.S., Wet-Steam Turbines for Nuclear Power Plants, PennWell, USA, 2005.In science and engineering, the word 'steam' is also used for water vapor, but usually when above the boiling point of water.Highly superheated vapors are gases that approximately follow the general gas law.Evaporation from a fluid takes place when liquid molecules at the liquid surface have enough momentum to overcome the intermolecular cohesive forces and escape to the atmosphere.Not wasting, but rather recovering and reusing as much of this sensible heat as possible is one of the main reasons behind condensate recovery.Variation of the second virial coefficient, from 3034, the second virial coefficient (B) depends on temperature.J mol-1 K-1 and T is the temperature (K).The dimer formation causes deviations from ideal gas behavior in gaseous water.This is not sufficient to change its energy appreciably, but is a sufficient rise in temperature to avoid condensation problems, given the average loss in temperature across the steam supply circuit.What is Condensate Recovery?If steam doing work in a reciprocating engine or turbine, cools to a temperature at which liquid droplets form; the water droplets entrained in the fluid flow will strike the mechanical parts of engines or turbines, with enough force to bend, crack or fracture them.The Benefits of Condensate Recovery, reusing hot condensate can lead to considerable savings in terms of energy and water resources, as well as improve working conditions and reduce your plant's carbon footprint.The main disadvantages are the added complexity and cost of the superheater tubing and the adverse effect that the "dry" steam has on lubrication of moving components such as the steam valves.
