  • 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

  • Coal-Fired Performance and Cost - EPA

    Combustion air is delivered to the boiler by forced draft (FD) and primary air (PA) fans. Induced draft (ID) fans are used to transfer combustion gases through a flue gas desulfurization (FGD) system, baghouse, and stack. The 400-MW case uses a fan arrangement of 1 PA/1 FD/1 ID, and the 600-and 900-MW cases use a 2 PA/2 FD/2 IDLearn More
