Abstract

The Low Temperature Circulating Fluidised Bed (LT-CFB) gasification process is briefly described together with the first test results from the new 500 kW test plant. The process aims primarily at co-firing low grade biomass and waste products at power plants and offer several advantages to directly co-firing: E.g. the ashes of different fuels can be kept separate, and corrosion and fouling of the furnace can be drastically reduced. Three fuels have been tested so far on this plant: High ash straw (12% ash, dry), dry matter from pig manure (28% ash, dry) and dry matter from biogas residue based on pig manure (44% ash, dry). All the tests have been very stable and a steady state content of ash components, e.g. potassium, in the ash and bed material was reached. The low temperature (max. 750°C) ensures that there are no agglomeration problems, and that almost 100% of K, Si, Ca and P is kept in solid state, and can be separated from the gas using only a simple hot cyclone. Mass- and energy balances show that the conversion efficiency from fuel heating value to energy content in the product gas is more than 90% and even higher efficiencies are anticipated in upscaled plants.
