3 Laboratory “Kleinhorst”
5
4 Energy Technology group Combustion of solid fuels “Energy from biomass and waste” Production of sustainable fuels (liquid, gas and solid) “Fuels from biomass and waste”
6
5 Combustion of solid fuels Coal fired power plants “biomass co-firing” Waste combustion
7
6 Co-firing of biomass in power plants (combustion) Focus on: Boilers with Ultra Supercritical steam conditions High ratio of biomass co-firing Slagging and fouling mechanisms Development of modelling tools Sponsors: TSA, KEMA

15
14 Fuel production from Biomass Flash pyrolysis Gasification Torrefaction
16
15 PYROLYSIS REACTOR Biomass Heat condenser Char Separation Gas Bio-oil Char Flash pyrolysis of biomass
17
Wood pyrolysis on lab scale - movie
18
17 PyRos pilot-plant with 30 kg/h biomass feed
19
PYROLYSIS REACTOR Biomass Heat condenser Char Separation Gas Bio-oil Char Near-future applications for pyrolysis oil
20
19 Algae and scrap tyres Oil from car tyres Oil from algae
21
20 Gasification in supercritical water Wet biomass Process conditions: 600 °C and 300 bar Production of a hydrogen or methane rich gas Process integrated reactor CO 2 separation C Heat exchanger supercritical reactor high P gas/liquid separator feedstock 600 °C 300 bar low P gas/liquid separator
22
Torrefaction Biomass is wet and bulky Biomass sources are distributed Pretreatment required!
23
Torrefaction process On-site preparation of biomass by drying, milling and torrefaction (no external energy requirement) Torrefaction: roasting of biomass at 250°C Friable and less fibrous Hydrophobic Preserved Reduced contaminations Homogeneous Higher heating value
