Differential pressure in a Circulating Fluidized Bed Combustion (CFBC) boiler refers to the difference in pressure between two points within the system, typically across the bed of the boiler. This pressure difference is crucial for maintaining the proper flow of gas and solid particles, ensuring efficient combustion and heat transfer. Monitoring differential pressure helps in optimizing the operation of the boiler, as it can indicate changes in bed density, flow resistance, or potential blockages. Maintaining the appropriate differential pressure is essential for the overall performance and efficiency of the CFBC boiler.

What is the difference in Boiler efficiency between CFBC Boiler and PF Boiler while firing powdery coal -50 percent less than 5 mm size?
Cfbc stands for circulating fludised bed combustion where as afbc is for atmospheric fluidise bed combustion afbc bed fluidising velocity is approx 4 m/s and in cfbc boiler fluidising velocity is 9-10 m/s. cfbc having low SOx & NOx comparative with afbc cfbc having higher efficiency up to 98.5 % then afbc boiler,cfbc boiler power consumption is more comparative to afbc.
What is the purpose of wall seal blower in cfbc boiler?
The wall seal blower in a Circulating Fluidized Bed Combustion (CFBC) boiler serves to maintain a proper seal between the combustion chamber and the external environment. By creating a slight negative pressure, it prevents the escape of flue gases and ensures efficient combustion by maintaining the required airflow. Additionally, it helps to enhance the overall efficiency of the boiler by optimizing the circulation of the bed material and improving the combustion process.
Function of root blower in cfbc boiler?
the pressure of the root blower is higher then the wind box pressure, because what ever the unburnt particle come from cyclone separator is collect in return leg this unburnt particle return back into combustion chamber so the function of root blower is to continuous circulation.
What is wing wall super heater in cfbc boiler?
A wing wall super heater in a Circulating Fluidized Bed Combustion (CFBC) boiler is an arrangement designed to enhance the temperature of steam produced in the boiler. It consists of tubes arranged along the side walls of the furnace, where hot flue gases from the combustion process pass over them. This setup increases the efficiency of steam generation by utilizing the high-temperature gases, thereby improving the overall thermal performance of the boiler. The design helps to reduce temperature gradients and optimize heat transfer.
What is the procedure for installing a water column on high pressure steam boiler?
To install a water column on a high-pressure steam boiler, first ensure that the boiler is shut down and depressurized. Then, locate the appropriate connection point, usually on the boiler's steam drum, and clean the surface to ensure a proper seal. Install the water column by securing it with appropriate fittings and ensuring all connections are tight to prevent leaks. Finally, connect the necessary gauge and ensure proper calibration before bringing the boiler back online.

Why loop seal provided in cfbc boiler?
loop seal is provided to stop the material from furnace to return leg back.It works with the help of diffrential pressure.There is the difference in the pressure of air beteen furnace and return leg.
What is the meaning of cfbc boiler?
The boiler in which fluidisation and combustion is done in the bed with the help of (pa,sa&ta)air and ash(un burnt particle) is re-used through cyclone and siphone to the bed is called cfbc boiler.
Function of root blower in cfbc boiler?
