Technology in Bubbling Beds, Fuels combined with inert materials, such sand or ash, or special media are burned inside a fluidized bed. Air is introduced into the bed at a precise velocity, which causes bubbling action both above and below the bed and causes the solid particles to mix equally and behave like a fluid. Solid fuels can burn in fluidized bed reactors with 90–95% efficiency or better, producing gas and heat at the required rate.

The fuel feeding devices, hoppers, elevator, cyclones, nozzles, ash settling chambers, ash removal mechanisms, fluidized bed furnace, fluidization air blower, pneumatic fuel feeding blower, instrumentation & control equipment, operation panel board, motors & electrical components are all part of the system.

• The fluidized Bed HAG system is capable of combusting several types of fuel such as coal, corncobs, wood scraps, and precipitates from waste water treatment, at high efficiency. In addition, the emission control system of toxic gases such as sulphur dioxide and oxides of nitrogen in this technology is easy to operate, inexpensive, and efficient.
• Virtually complete combustion at low excess air level.
• Increased energy recovery potential and system efficiency.
• Odor elimination.
• Minimal Maintenance.
• Lower capital costs.
• Fully Automated system, which maintain automatically all the operating parameters of the system according to fuel.

Favourable Ash Properties: The high combustion efficiency of a fluidized bed results in a reduced amount of inorganic material as fine ash. Low combustion temperatures in the fluidized bed minimize the formation of toxic materials that might carry over with the ash..
