26/6/2017 · Assume boiler operates at 10 cycles of concentration, and the residual boiler water alkalinity, M, is 250 ppm. To develop this alkalinity, we need 25 ppm soda ash (as CaCO 3 ) in the feedwater (250 ppm boiler alkalinity divided by 10 concentrations), over and above the amount required to neutralize non-carbonate hardness in the feedwater.

Read Moremakeup water, total alkalinities may be allowed as high as 1200 ppm when utilizing a specific boiler water antifoam and conducting a recommended embrittlement study. Similarly, silica concentrations can be allowed above those indicated where steam is

Read MoreThe following represents a typical boiler plant from which we can calculate the demand for a softener. 1. Determine Water Hardness. Analysis received or taken is in parts per million (ppm). Convert to grains per gallon (gpg). 342 ÷ 17.1 = 20 gpg. 2. Determine Boiler Horsepower.

Read MoreBy applying the 3kW x 0.014 = m formula the maximum water volume of the boiler is calculated; then subtract 20% (typical heat engineering boiler sizing tolerance margin) to give the estimated water volume in the system. In making this calculation it is very

Read MoreMake-up water for both a high-pressure steam boiler and for distribution of the district heating are needed. The make-up water for the high-pressure steam boiler is demineralised according to the patented water treatment principle of UPCORE, combining all the known advantages of water demineralisation through ion exchange with the counter-flow principle.

Read MoreWe 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 …
