  • Boiler Operations That Affect Efficiency (Part 1)

    In variable pressure operation, boiler pressure is varied to meet turbine requirements. This can significantly improve cycle efficiency when operating at low loads (15 to 40% of maximum continuous rating, or MCR). However, boiler response to turbine requirementsLearn More

  • Boiler (power generation) - Wikipedia

    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.Learn More

  • BOILER SAFETY MEASURES – Boiler World Update

    25/5/2021 · Furnace explosion is the main cause in severe boiler accidents that leads to escaping out of flue gas and ash from the furnace and allied pressure part components & resulted into fatal accidents. Therefore, utmost safety is required to be taken while working on boiler and boiler mountings.Learn More

  • Plant Engineering | Maintaining boiler safety

    Low-water trips protect boiler pressure parts by shutting down the fuel combustion process, eliminating high temperatures in the furnace when the natural circulation cooling process is interrupted. Control of the boiler drum level is sophisticated, and even the best-tuned control systems cannot always prevent a low-water condition.Learn More

  • Boiler Pressure - an overview | ScienceDirect Topics

    Boiler pressure is the key factor for determining the need for a condensate polishing system. With a steam generator plant with low steam pressures (below 40 kg/cm2 ), the requirement of the CPU is usually avoided. Hard scale formation and boiler metal corrosion can easily be prevented through FW treatment before sending to the boiler proper.Learn More

  • Boiler Operation with Low Furnace Pressure - Bright Hub …

    23/1/2010 · High furnace pressure in boilers is a direct indication of a disturbance in combustion performance. The rate of change in the furnace pressure can vary from a simple sudden surge due to fuel variations to a huge furnace explosion. All forced draft fan trips in a boiler will cause a boiler trip.Learn More

  • Boiler Furnace Pressure Excursion and Set Points

    At steady state operation, P is held constant at approximately atmospheric pressure by balancing the resident mass M and the existing temperature T. Furnace temperature in a boiler is not directly controlled and depend on the thermal balance between the heat in (in the burning fuel and heated air) and the heat out (in the flue gas and heat transferred to the pressure parts). The resident mass is automatically balanced by controlling the flue gas flow out of the boiler to maintain a given furnace pressure. When the fuel input is terminated, this balance no longer exists. The flue gas being pulled out f the furnace by the ID fan is now being replaced only by preheated air rather than by the products of combustion in the firing zone. The average temperature of the gases resident in the furnace (or other subsystem) at any given time following fuel trip will decrease rapidly. Because of the temperature drop, the pressure in the furnace …Learn More
