(kW/ton of installed cooling capacity)specifies the boiler blowdown flow rate as a fraction ofsteam losses from a steam turbine (i .e., steam enteringthe turbine less condensation pumped from the condenserinto the feedwater system). If no steam turbine isspecified, then the blowdown calculated by this parameteris zero.accepts a code-word that defines the boiler controlscheme. If the boiler operates only when a boiler loadis passed from SYSTEMS, the code-word should beDEMAND-ONLY, which is the default. If the boileroperates in a standby mode whenever the HEATING-SCHEDULEin SYSTEMS is "on", even if there is no load, theappropriate code-word is STANDBY.accepts a cOde-word that specifies the type of fuel usedin a boiler. The allowable code-words are DIESEL-OIL,NATURAL-GAS, FUEL-OIL, LPG, COAL, METHANOL, and BIOMASS.is the fraction of the total capacity of the electrichot-water boiler lost through skin or leads while it isoperating (does not include circulation losses).is the fraction of the total capacity of an electricsteam boiler lost through skin or leads while it isoperating (does not include circulation losses).is, for a hot-water boiler, the ratio of fuel input (Btu)to heat energy output at full load.specifies the makeup water temperature for a boiler (OF).specifies the effectiveness of blowdown heat recovery fora steam boiler.is, for a steam boiler the ratio of fuel input (Btu) toheat energy output.is, for a domestic water heater at full load, the ratioof fuel input (Btu) to heat energy produced.V.30 (Revised 5/81)
