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.

What ar the fluid zed bed boiler ant it's types?

A fluidized bed boiler is a type of industrial boiler that uses a fluidized bed of solid particles, typically sand or ash, to combust fuel efficiently at lower temperatures. The process involves blowing air through the bed, causing the solids to behave like a fluid, which enhances heat transfer and combustion efficiency. There are two main types of fluidized bed boilers: bubbling fluidized bed (BFB) boilers, where the bed bubbles up due to air flow, and circulating fluidized bed (CFB) boilers, where particles are continuously circulated through the system for better combustion and heat transfer. Both types are known for their ability to burn a wide variety of fuels, including biomass and waste materials, with reduced emissions.


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.


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 channeling in fluidized bed?

Channeling occurs when a fluid flowing through a bed is not evenly dispersed throughout the bed. For instance large diameter reactors have more frequent channeling problems where liquid is prone to channel along the reactor walls. Channeling should be avoided and reduces efficiency and conversion since reactants do not have proper contact with catalysts or separation media.


Why is the boiler water circulating pump required for EGB?

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?
