It is a water tube, forced circulation boiler, where the feed water is compressed to supercritical pressure to prevent the formation of bubbles in the water tube. The compressed water feed increases the density of the water such that its density and that of the steam become the same, which reduces the latent heat in the water to zero making it Get Price
requirements. Every time a power plant is turned off and on, the boiler, steam lines, turbine, and auxiliary components go through unavoidably large thermal and pressure stresses, which cause damage. This damage is made worse for high temperature components by the phenomenon we call creep-fatigue interaction.Get Price

May 22, 2019 · Boiler Pressure. An increase in the boiler pressure is in the result limited by material of the reactor pressure vessel. The case of the increase in the average temperature at which energy is added by heat transfer, requires either a superheating of steam produced or an increase in the pressure in the boiler (steam generator).Get Price
The working pressure The distribution pressure of steam is influenced by a number of factors, but is limited by: • The maximum safe working pressure of the boiler • The minimum pressure required at the plant As steam passes through the distribution pipework, it will inevitably lose pressure due to: • Frictional resistance within the pipeworkGet Price
The improvement in boiler efficiency can be determined by measuring the stack flue gas temperature. The stack gas temperature should decrease when the turbulators are installed. As a rule of thumb, a 2.5% increase in the boiler efficiency is expected for each 50°C (90°F) decrease in the stack flue gas temperature. •Get Price
