  • Steam Calculators: Boiler Calculator

    Mar 17, 2015 · Steam, 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.Learn More

  • Boiler Feed Water Flow Rate Requirements Chart | Nalco PTS

    Feb 27, 2019 · This steam has a corresponding latent heat of 794 btu/lb. If the steam flow is 1,000 pounds per hour, then the total heat input per hour is 794,000 btu. Determine the process heat that is removed from the steam flow. For instance, assume a vessel's heating system removes 30,000 btu/hr to perform a reaction.Learn More

  • Calculate How To

    In the following equations, the operating cost of the boiler is CO per hour and the process requires S pounds/hour (lb/h) of steam. To deliver this much steam, it is necessary to actually generate (1+X)S lb/h of steam, where X is a factor typically ranging from 5 to 20%. So we already have two distinct equations to determine the cost of steamLearn More

  • How to size a condensate return unit - Xylem Applied Water

    May 20, 2015 · Boilers are rated to tell you how much steam they can put out, in terms of boiler horsepower, pounds per hour of steam, BTUs or other ratings. It makes sense to convert the information you get from the engineer or customer into common terms across the system. When everything is said and done, what comes back from the boiler as condensate is Learn More

    The steam is raised in boilers at 70 bar pressure and superheated to 500 oC. The steam is expanded in a turbine and then condensed at 0.05 bar. The process heat is provided by the steam bled from the turbine at an appropriate pressure, and the st eam condense d in the process heat exchanger is returned to the feed water line.Learn More
