In cfbc boiler fuel system like a very important funtion of in all process.

fuel feeding have two types one is over beding system and other one is under bed system.In over bed system coal is carried by conveyer belt from bunker to spreader that's time coal size approx 6-10 mm crushed.spreader distribute coal on the surface of bed uniformly.This type of fuel feeding system accept over size of fuel also.In compared with under feeding system this is more reliable.Now these days have some boiler have both feeding system.In under bed feeding coal size crushed approx 1-6 mm which is throw from conveyer to combustion panel.

In the automobiles, in the fuel system,sometimes large amount of vapour formation takes place at higher temperature.The cause is evaporation of some of the more volatile components of the petrol. Bubbles of vapour from in the fuel system can prevent the easy flow of fuel. This is called vapour lock.

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.
