Below are listed the main advantages of the Low Temperatura Circulating
Fluidized Bed. From these it is clear that this is a flexible machine in many
ways and that it can serve many purposes.
A variety of difficult and low value fuels can be fed into the Low
Temperature Gasifier. Despite this a stable and reliable production of
combustible gas can be maintained.
Easy Gas Cleaning
Due to mainly the low exit temperature, ash components such as K and P - also
without prior raw gas cooling - can be efficiently separated along with the ash.
In case of raw gas cooling prior to (even more efficient) particle filtering,
the low dew point of essentially only light tars is a further major
Recycling of nutrients
By keeping especially potassium and phosphorus in the non-sintered ash, it is
possible to recycle these valuable nutrients to the farming industry.
Furthermore a low content of heavy polyaromates (PAH) means that the ash often
are allowed to be returned directly to e.g. farming land.
The Low Temperature Gasifier is fully scalable allowing great flexibility for
adapting it to different uses.
By producing a cleaned and potentially also reformed gas, the Low Temperature
Gasifier can have many different applications such as producing combustible gas
for boilers, gas turbines, engines, fuel cells and synthesis processes. Even the
production of bio oil and/or biochar is possible.
Reduction of CO2 emissions
The use of Low Temperature Gasification will allow a reduction of CO2 from
highly efficient and timely controllable power generation which is in accordance
with DONG Energys 85/15 vision.
