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.

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 circulating fluidized bed boiler?
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 is fluidized-bed combustion?
Fluidized-bed combustion is a technology used for burning solid fuels, such as coal or biomass, in which the fuel particles are suspended in an upward-flowing stream of air. This creates a fluid-like state, allowing for more efficient and uniform combustion. The process enhances heat transfer and reduces emissions of pollutants due to lower combustion temperatures. It is commonly used in power plants and industrial applications for its efficiency and environmental benefits.
What is the channeling in distillation column?
In distillation coloum the channeling means is the unequal wetting of the packings in the tower. If channeling occurs, poor mass transfer happens, and therefore, less efficiency of the tower happens. AWAIS AFRIDI DEPARTMENT OF CHEMICAL ENGINEERING UNIVERSITY OF GUJRAT...
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.
