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 differential pressure in cfbc boiler?
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 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 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 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 afbc boiler?
Atmospheric Fluidized Bed Combustion Boiler (AFBC boiler) is a type of operational boiler. In a AFBC boiler a little more fluidized bed combustor is added than a conventional shell boiler.
