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.
Difference between hot cyclone and cold cyclone in cfbc?
Main difference between hot cyclone and cold cyclone is 1. In hot cyclone flue gas temperature is above 800'c., in cold cyclone is is 400 to 500'c. 2. For 3-pass boiler we are used hot cyclone. 3. In reheater system we use hot cyclone to improve the efficiency of boiler.
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 bras are available for woman who need an H cup bra?
There are many bras that make an H cup. Jeunique, Tab, CFBC, Glamorise, and Goddess are among them. I would highly recommend that you have a Custom Bra Fitting to make sure you end up in the right size, since all brands are a little different. For instance if you wear a H cup in Jeunique, you will fit better in a J cup in a CFBC. Keep in mind that Bra size is not as important as how it fits. Everyone is different and some bras fit certain body types better than others.
