2019-9-29 · On a ship, the fire room, or FR or boiler room or stokehold, referred to the space, or spaces, of a vessel where water was brought to a boil. The steam was then transmitted to a separate engine room, often (but not always) located immediately aft, where it was utilized to power the vessel. To increase the safety and damage survivability of a

Boiler Efficiency |

Boiler efficiency, when calculated by the ASME heat balance method, includes stack losses and radiation and convection losses. But what factors have the most effect or “sensitivity” on boiler efficiency? As discussed earlier, the basic boiler design is the major factor. However, there is room for interpretation when calculating efficiency.
