Pressurized Fluidized Bed Incineration System

Sludge treatment facility

Structure and Principle

This pressurized fluidized bed incineration system combines a turbocharger (supercharger) with a fluidized bed incinerator. In this system, dewatered sludge is incinerated under a pressure of 150 kPa・G. Flue gas generated by the combustion is under pressure, so it flows towards the stack which is at low pressure, and it is introduced into a turbocharger through an air preheater and a dust collector.
The system does not need a forced draft blower and an induced draft fan which consume much electric power. So 40-60% of electric power and CO2 are reduced, and the system is self-driven without air supply and exhaust power if sludge is continuously supplied as fuel.
