Proper sizing of Boiler Feedwater System
2017/11/29 · One 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

Boiler water consumption - Lenntech
This equation doesn’t take account of the process leaks, the windage and drift which are just forms of uncontrolled blowdown. 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.

Boiler feedwater - Wikipedia
Boiler feedwater is an essential part of boiler operations. The feed water is put into the steam drum from a feed pump. In the steam drum the feed water is then turned into steam from the heat. After the steam is used it is then dumped to the main condenser. From the condenser it is then pumped to the deaerated feed tank. From this tank it

Boiler water - Wikipedia
Acceptable phosphate concentrations decrease from 140 mg/L in low pressure boilers to less than 40 mg/L at pressures above 1,500 pounds per square inch (10,000 kPa). Recommended alkalinity similarly decreases from 700 mg/L to 200 mg/L over the same pressure range. Foaming problems are more common with high alkalinity.
