Step 42: Enter number of economizer tubes connected to manifold (in this case it is same as number of tubes in row). This is needed to calculate water velocity in tubes. Previous step was the last one in data entry process.

Chat OnlineThe Condenser, Reheater and Feedwater Heaters. Consider Example 1. The steam tables show that the enthalpy of the turbine inlet steam is 1,505.9 Btu per pound of fluid (Btu/lbm). Thermodynamic calculations indicate the exiting enthalpy from the turbine is 1,080.9 Btu/lbm (steam quality is 93 percent).

Chat OnlineDec 05, 2017· Sizing a Steam Boiler. December 5, 2017. By Ron Beck, U.S. Boiler Company. Last month we discussed sizing a hot water boiler with a heat loss calculation. Unlike a hot water boiler, a steam boiler is sized by determining the square foot of radiation connected to the steam system. Once thats been determined, you can accurately select a boiler

There are two methods of assessing boiler efficiency. 1) Boiler Efficiency by Direct Method: Where the energy gain of the working fluid (water and steam) is compared with the energy content of the boiler fuel.

Chat OnlineSteam provided to the deaerator provides physical stripping action and heats the mixture of returned condensate and boiler feedwater makeup to saturation temperature. Normal design practice is to calculate the steam required for heating, and then make sure

Chat OnlineThese steps apply to pump selection for an industrial steam boiler with a horsepower range of 100 to 1,200 and a design pressure of 150 to 500 psig.

Chat OnlineSteam, Boiler, and Blowdown Pressure are the same. Combustion Efficiency is the % of fuel energy that is directly added to the feedwater and not otherwise lost or used. Blowdown Rate is the % of incoming feedwater mass flow rate that leaves the boiler as a saturated liquid at boiler pressure.

Chat OnlineUse boiler horsepower to calculate steam flow. Boiler horsepower is not related to mechanical horsepower. It is a boiler industry rating that predicates the amount of saturated steam a boiler will generate starting with water at 212 degrees Fahrenheit and 0 pounds per square inch gauge (psig--meaning atmospheric pressure) and ending with steam at 212 F and 0 psig.
