RotoGasifier Advanced Gasifier
 |
|
The RotoGasifier Advanced Gasifier ["RG"] is
a recirculating horizontal gasifier. It is
flexible in sizing, can be deployed as a mobile unit and plants
include the world's largest pellet plant, used to create
renewable fuel in the USA, for the UK. |
The RotoGasifier commenced development in the early
1990's as biomass dryers. Initially deployed as pyrolysis units,
the systems have been
modified to achieve full gasification by increasing temperature
and process duration, which is an approach common to other Advanced Gasification
systems. The horizontal layout allows for rotation, which facilitates
accepting a wide range of feedstocks and the systems can thus be designed, scaled and
deployed to suit most needs.
Current systems range from the
smallest unit at 240kg/day - which is a mobile system suitable for testing, emergency and disaster relief
- to the largest RotoGasifier, which has a capacity exceeding 1,000 dry
tonnes per day and is used to create RDF (renewable energy
pellets), shipped to the UK from the USA. RotoGasifiers are currently operating mostly for waste biomass
processing, e.g. bagasse (sugar cane waste) processing in
Louisiana - similar in nature to separated MSW kitchen scraps.
While Fluidized Bed Advanced Gasification is the highest
yielding Advanced Gasification system, RotoGasifiers are
intended as the primary
technology for MSW processing due to their scalability and
robust handling characteristics.
