Get a QuoteLets now look at a few boiler specifications: Ideal Logic Combi 30: specified flow rate 12.4 litre/min for 35C rise requires 12.4/60 x 35 x 4.2 = 30.4kW. The specification states DHW output (kW) Max = 30.3kW.
Get a QuoteThe more powerful a boiler is (represented in kW) the faster the boiler will be able to heat the water coming into your home. However it is important to recognise a high kW output will not always increase your flow rate. If you have 10 litres per minute coming into your property you will only be able to receive 10 litres per min of hot water.

S = Weight density lb/ft 3 or N/m 3. V = Velocity in pipe ft/s or m/s. V 1 = Upstream velocity ft/s or m/s. V 2 = Downstream velocity ft/s or m/s.

Get a QuoteIf for example it takes 5 seconds then divide 60 into 5 this then gives you a flow rate of 12 litres per minute which is more than enough to meet the boiler manufacturers minimum specification if how ever the flow rate is less then 9/lpm then you will suffer from poor cold water service flow rate.
Get a QuoteIt means that the gas flow in the pipe has its maximum depending on the available energy on beginning. If the pressure drop is sufficiently high the exit gas velocity will reach the speed of sound and maximum weight gas flow rate will occur.
Get a QuoteUsing the calculated feedwater mass flow and blowdown rate: Blowdown Mass Flow = Feedwater Mass Flow * Blowdown Rate. [ Blowdown Mass Flow = 2.7 klb/hr = 42.4 klb/hr * 0.064 ] Using the Steam Property Calculator properties are determined using Steam Pressure and Quality = 0 (Saturated Liquid).
Get a QuoteMar 17 2015 · The feedwater flow rate can be calculated from steam mass flow and blowdown rate: Blowdown Mass Flow = Feedwater Mass Flow * Blowdown Rate; Steam Mass Flow = Feedwater Mass Flow - Blowdown Mass Flow; Steam Mass Flow = Feedwater Mass Flow - Feedwater Mass Flow * Blowdown Rate; Feedwater Mass Flow = Steam Mass Flow / [ 1 - Blowdown Rate]

Get a QuoteHowever it is critical to measure the exact flows of the boiler's cooling circuit to avoid undershooting of a certain flow rate threshold which can lead to a whole plant shutdown. Previously installed Vortex flow metes have not been able to cope with the extremely demanding environment of dynamic temperature and pressure swings up to 260°C ...

Get a QuoteThe output specifications for a boiler will often show the maximum flow rate that the boiler can provide at a specific temperature. For example you might see a flow rate of 12 l/min at a temperature of 40 degrees centigrade. This is how much water it can send out to the taps in your home at that temperature.
Get a QuoteFeb 05 2013 · The flow rate can be calculated based on the consumption and power of your boiler. So if you have 24 kW boiler maximum flow rate is about 2.6 m3/s on standard conditions. Equation for this is like this: Q = 3600 * P / Hd = 3600 * 24 / 33600 = 2.57 m3/h on standard conditions (t=15 C
