Steam Pressure Reduction: Opportunities and Issues

Steam generation systems are found in industry and in the commercial and institutional sectors. Some of As tested, the boiler stack temperature varies linearly with steam pressure. A savings of 0.4% to 0.8% of the fuel input can be expected from lower

Operation and maintenance schedule of a steam turbine plant and …

Steam pressures and temperatures in current practice have reached 97–164 bar and 480–565°C or 593°C. The rate of increase in efficiency with increase in pressure becomes less as the pressure increases. A limit to the practicable operating pressure is set by the difficulty in separating moisture from steam in the boiler drum.
