Moreover, the water consumption is usually determined with the blow-down brine, depending on the recirculated steam and the make-up water concentration. B=S x (1 - r) x m / b - m. B = Blowdown. S = Steam rate. b = boiler water TDS concentration. m = make-up water TDS concentration. r = fractional condensate return

View MoreAug 28, 2018· Consider a pot of boiling water maintained at a constant level of 1,000 gallons by the addition of tap water. If the tap water used for makeup contains 1 lb. of solids in every 1,000 gallons, and initially the pot is filled with 1,000 gallons of tap water, the system water is said to be at 1 cycle. This is because no evaporation has occurred yet.
View MoreTo figure this, you begin by calculating the flow to the economizer. Use 34.5 pounds of steam per boiler horsepower and a gallon of water weighs 8.3 pounds. A 200 HP boiler will then develop approximately 6900#/hr and at 25% makeup is 1726#/hr divided by 8.3#/ …
View MoreMar 17, 2015· Blowdown Mass Flow = Feedwater Mass Flow * Blowdown Rate. Using the Steam Property Calculator, properties are determined using Steam Pressure and Quality = 0 (Saturated Liquid). The Specific Enthalpy is then multiplied by the Mass Flow to get the Energy Flow: Blowdown Energy Flow = Specific Enthalpy * Mass Flow.
View MoreThe importance of the boiler feedtank, where boiler feedwater and make-up water are stored and into which condensate is returned, is often underestimated. Most items of plant in the boiler house are duplicated, but it is rare to have two feedtanks and this crucial item is often the last to be considered in the design process.
View MoreOne boiler horsepower = 34.5 lbs/hr of steam (or water) from and at 212o F. We also know that one-gallon of water weighs 8.37 lbs. To calculate the storage tank needed use the following formula: BHP X 34.5 ÷ 8.337 lbs ÷ 60 min. X 10 = minimum useable capacity in gallons. For example, if you have a 500 HP boiler the calculation will be as follows –
