If the boiler is up to temperature, then the problem is with the pump. If the boiler is cold you should call a pro, as there is no way to diagnose it from here with out more info.
TDBFP = Turbine Driven Boiler Feed Pump
In boiler feed pumps usually the discharge pressure is 20 to 30 times tie suction Pressure so to protect the pump balancing line is given from discharge to suction.
3 things 1) the plumber sends you a bill 2) the new pump is expected to move more water through the loop than the old pump, usually at a significantly higher unit cost but only slightly higher electrical consumption 3) ideally result 2 will move more water around the radiant loop resulting in a less temperature drop around the loop, more even heat radiation for better comfort and a higher return water temperature into the boiler potentially improving combustion efficiency and boiler lifespan, but "your mileage may vary"
The boiler feed pump pumps hot feedwater into the boiler. The boiler pressure is to high for water to flow into it by gravity, so a pump is required.
You must mean "why can i model a boiler and pump" as an electrical circuit. The answer is "elecrical components can be arranged to correspond to a useful mathematical model for the boiler and pump."

A digester feed pump forces water to a boiler. It works by transferring cool water to the boiler to be heated.
it is 500N
NO!
Boiler feed pumps are an important part of any boiler operation. They control the amount of water fed to the boiler and the manner in which it is fed.
If the boiler is up to temperature, then the problem is with the pump. If the boiler is cold you should call a pro, as there is no way to diagnose it from here with out more info.
Boiler feed pump's suction pressure be aprox. 15Kg/cm2 and discharge pressure be 180Kg/cm2. So the balancing line balance the pressure and protect the boiler feed pump. my quastion is that what is the working principal of balancing leak off
Pump efficiency can not be taken as given.
