  • What is the safe pressure for a hot water heating system?

    The water pressure in a hydronic boiler shouldn't be over 12 to 15 psi. It should have only enough pressure to raise the water a few feet above the top of the highest point in the piping system. A 12 psi setting will lift water 28' above the fill valve.

  • What is the temperature of a boiler in a power plant?

    Jan 15, 2017 · If a power plant has both CFBC and WHRB boiler operating for same TG then there furnace temperature will have similar range of temperature.So we can't generalise a certain temperature for CFBC or WHRB boiler or any other boiler.In some cases it' s temperature range varies from 850 to 950 degree centigrade.

  • Lower Pressure Operation of Boiler than Designed

    Implications of Operating Boilers at Lower Pressures than Design Pressure. It is found that in a 176 kg/cm 2 steam cycle with 540 degree C superheated steam temperature for a 500 MW power plant lowers the overall plant heat rate around 1.2 kcal/hr. However a reduction of 10 degree C in superheated steam temperature lowers the overall plant heat rate around 9 kcal/hr.

  • Lower Pressure Operation of Boiler than Designed

    In constant pressure operation the boiler superheater outlet pressure is designed to be maintained constant from as low as 40% of the rated maximum continuous load. In sliding pressure boilers the superheater steam outlet pressure is slowly taken up at a particular ramping rate acceptable to both boiler and turbine designers.

  • Boiler (power generation)

    A boiler or steam generator is a device used to create steam by applying heat energy to water.Although the definitions are somewhat flexible, it can be said that older steam generators were commonly termed boilers and worked at low to medium pressure (7–2,000 kPa or 1–290 psi) but, at pressures above this, it is more usual to speak of a steam generator.
