The function of back pressure valve is to prevent back flow to the pump in case there is an obstruction on downstream side of valve.

externally fired
a boiler operator should know and be capable to run it smoothlyt
TDBFP = Turbine Driven Boiler Feed Pump
By measuring outlet temperature of water at downstream of pump and upstream of boiler.
A boiler with a circulating pump and pipes to convey heating water around a house, through radiators or underfloor pipes.
The function of back pressure valve is to prevent back flow to the pump in case there is an obstruction on downstream side of valve.
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.
Circulating fluidised bed combustion
steam boiler
Function - It adds the pressure to the feed water before it entyers into boiler feed pump suction Advantage - Ensures high margin NPSH A for boiler feed pump spinning at high rpm (5250Rpm) Drive for booster - Normally @1450 rpm Type of impeller- Mostly preferred Double suction
If the pump is not circulating coolant insure that the thermostat is not stuck closed. If the thermostat is ok then the pump will have to be replaced.
I think because it works more like a heat exchanger taking heat from the exhaust gas, rather than a "standard" boiler with a furnace?An EGB needs a pump to circulate the water through the pipes in the exhaust stack, whereas a furnace-heated boiler can use convection to move the fluid through the system..?Might have something to do with lower temperatures in an EGB?
A circulating fluidized bed boiler helps to hold fuels in a solid states in upwards air jets when combustion occurs. This creates a mixture of unstable solids and gasses, which can promote chemical processing.
The boiler and pump in a heating system are similar to a cell in a circuit as they both provide the necessary energy or power to the respective systems. The boiler generates heat energy for heating, while the pump circulates the heated water. Similarly, a cell in a circuit provides electrical energy for the components in the circuit to function. Both systems rely on a source of energy to power their operations.
