What are boilers?
-
The bypass is not required.
-
Can be adjusted as per the steam requirement.
-
No pressure loss
-
Pumps are stopped if there is no need for water
-
Less maintenance and operation costs
Boilers
A steam boiler is a pressurized tank. To avoid boiler failure and loss of life in the plant, the boiler must have the desired amount of water. To maintain the safe water level standard, a feed water pump is used. In Boiler Feed Pumps, the electric motor is connected to the pump body by the mechanical coupling.
The pump must generate the pressure needed to push the feedwater into the boiler. And the pressure generated must be greater the steam pressure in the boiler. During low flow conditions, the minimum flow is maintained to prevent over-pressuring. In large applications, multiple pumps are installed parallel to each other.
