  • Such watertube boilers in thermal power stations are also called steam generating units. The older fire-tube boiler design, in which the water surrounds the heat source and gases from combustion pass through tubes within the water space, is a much weaker structure and is rarely used for pressures above 2.4 MPa (350 psi).

  • Types. There are two types of air preheaters for use in steam generators in thermal power stations: One is a tubular type built into the boiler flue gas ducting, and the other is a regenerative air preheater. These may be arranged so the gas flows horizontally or vertically across the axis of rotation.

  • the field with boilers with less heating surface per square foot overheating, specifically the rear tube sheet attachment. The optimized furnace has a heat release rate of 125,000 BTU/hr/cubic foot compared to a boiler industry average of 150,000. The low heat release rate keeps flue gas temperature lower and reduces thermal expansion.

  • Available in vertical or horizontal configurations, tubular air heaters increase thermal efficiency by recuperating heat from the exit flue gases. This heat is used to preheat the air coming into the boiler unit, which means it takes less energy to achieve proper temperatures – resulting in better thermal efficiency.
