Get priceJan 28, 2017 · I don't have experience in calculating demineralized water demand for amine contactor or chemical dilution. So, in this post, I assume demineralized water is used as boiler feed water. Let say we have boiler with capacity of 10 ton/hour. Assume blow down rate is 3%. Demin water demand is = (1+3%) x 10 ton/hour = 10.3 ton/hour
Get priceSince you usually talk about gpm to the boiler, a rule of thumb is divide the number of PPH of steam out by 500 and that is the number of gpm you need to put into the boiler. 1000 PPH steam/500 = 2 gpm into the boiler. If the feed water temperature is less than 212F and the pressure is above 0 psig then the number of PPH of steam you can
Get priceOne 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
