1. ENERGY PERFORMANCE ASSESSMENT OF BOILERS

In case of boilers with intermittent blowdown, blowdown should be avoided during the trial period. In case of boilers with continuous blowdown, the heat loss due to blowdown should be calculated and added to the heat in steam. 1.6.3 Boiler Efficiency by Direct Method: Calculation and Example Test Data and Calculation

Boilers - University of Alabama

Fire-Tube Boiler (~1800) The fire tube boiler, the oldest design, is made so the products of combustion pass through tubes surrounded by water in a shell. The furnace/flame volume can either be inside or external to the shell that contains the water. The upper steam capacity of fire tube boilers is about 20,000 Ibm/hr, and the peak pressure

Return Condensate to the Boiler - NREL

This amount is the flash steam loss. Return Condensate to the Boiler When steam transfers its heat in a manufacturing process, heat exchanger, or heating coil, it reverts to a liquid phase called condensate. An attractive method of improving your power plant's energy efficiency is to increase the condensate return to the boiler.
