### Boiler Feed Water Flow Rate Requirements Chart | Nalco PTS

9 litres of water weighs 9 kilos, so the flow is 0.15 kg per second. So we get 0.15 x 50 x 4.2 = 31.5 kJ/sec (1 kiloJoule per sec = 1 kiloWatt) ( rapidtables.com/convert/electric/kj-to-kw) Which broadly means you need something like a 31.5 kilowatt power output on your boiler without allowing for any inefficiencies.

Dec 29, 2006 · This chart relates boiler horse power to the flow rate in gallons per minute and pounds per hour. In this case, we need a demineralizer or softener rated for a maximum flow rate of 28 gpm. It will be less depending upon how much condensate is returned. The next part of this question is what water quality is needed for the application.

Water Circulation - Boiler Capacity in kW - Temperature drop in degrees Celsius 1 kW = 3,412 Btu/h = 1.341 British hp Example - Water flow through Boiler A boiler with capacity 50 kW increases the temperature of the circulated water with 20oC - the water flow through the boiler …

### Boiler Flow Rates — Heating Help: The Wall

The heat flow rate can be calculated as h = (4.2 kJ/kg o C) (1000 kg/m 3 ) (10 liter) (1/1000 m 3 /liter) ((100 o C) - (10 o C)) / ((30 min) (60 s/min)) = 2.1 kJ/s (kW)
