Read MoreBoiler Flow Rates Explained - what is a boiler flow rate and how does it affect my hot water supply? When manufacturers & installers talk about water heaters, especially combi-boilers, a key phrase used is "flow rate".In most cases this is really referring to how

Read MoreIn 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. The steam pressure and steam boiler manufacturer will help determine what the water quality needs to be.

Read MoreSteam Production When heat is added to water, its temperature rises at a rate of 0.56 C (1 F) for each heat input of 2.095 kJ/kg (1 Btu/lb) If we take water at 0 C (32 F) and we add 419 kJ/kg (180 Btu/lb) then we will increase the temperature of the water by 100 C

Read More2015/3/17 · Step 2: Determine Feedwater Properties and Mass Flow. The feedwater flow rate can be calculated from steam mass flow and blowdown rate: Using the Steam Property Calculator, properties are determined using Deaerator Pressure and Quality = 0 (Saturated Liquid). The Specific Enthalpy is then multiplied by the Mass Flow to get the Energy Flow

Read More2021/4/4 · Use btu/hr (British thermal units/hour) heat input rate to calculate boiler steam flow. It takes 970.28 btu/hr to produce 1 pound of steam at the above conditions. If 50 million btu/hr are being applied to the boiler, divide by the 970.28-btu/lb to yield 51,531-lb/hr steam flow. flow.
