The fuels burnt in the furnace and combustible gasses move into the fire tubes, travel through these tubes from rear to front of the boiler drum and finally the gases come into the smoke box. The hot gasses in the tubes under water transfer heat to the water via the tube walls. Due to this heat energy steam bubbles are created and come upon the water surface. As the amount of steam is increased in that closed drum, steam pressure inside the drum increases which increase significantly the boiling temperature of the water and hence rate of production of steam is reduced. In this way a fire tube boiler controls its own pressure. In other words this is a self pressure controlled boiler.
Factors regarding thermal efficiency, you can see another article of small series (method of improving the thermal efficiency of the boiler), a detailed explanation of the reasons for you to influence the thermal efficiency of the boiler.
Waste coal, high sulfur coal and even discarded tires play to the strengths of CFB. That’s because CFB boilers can use these fuels while producing low emissions. Furthermore, CFB can use a wide variety of opportunity fuels almost interchangeably without major, if any, plant modifications.
