Royal Institute of Technology (KTH)

KTH Innovative Combusion and Gasification Lab (KTH CombGas) enables users to study fundamental combustion physics in two innovative fuel utilization approaches with particular interest to biomass applications: high-temperature fuel/oxidant preheating (also known as flameless combustion) and catalytic combustion. The high-temperature preheat concept is also applied in a gasification rig designed to shed light upon critical transport phenomena.

KTH offers 4 facilities in total.

1. High-temperature Air and Steam Gasification (HTAG) Test Facility

Unique facility in the world offering preheating gasification agent (air/steam) levels up to 1300°C possible, a very uncommon level for any type of gasification equipment. Fuels include woody biomass and organic wastes. Capacities range from as low as 20 kW up to 800 kW.

2. High-temperature Air Combustion Semi-industrial Test Facility (HiTAC)

Unique large-scale HiTAC research furnace in Europe (500 kW), enabling users to conduct fundamental research in synthesis gas from biomass thermal conversion (gasification and/or pyrolysis) combustion test with advanced combustion technology.

3. High-pressure homo/heterogeneous, full/hybrid catalytic combustion & conversion test facility

Unique large-scale HiTAC research furnace in Europe (500 kW), enabling users to conduct fundamental research in synthesis gas from biomass thermal conversion (gasification and/or pyrolysis) combustion test with advanced combustion technology. Extremely flexible operation; for instance four advanced burner systems are available. Unit is fully instrumented with e.g. 120 thermocouples, water-cooled suction pyrometer, water-cooled radiation heat flux probe, micro-GC, and NOx chemiluminescence analyzer. Accompanying research-scale furnace available for complementary studies such as optical measurements.

4. Pressurized fluidized bed reactor facility

Extremely high pressure levels (3.0 MPa) in a relatively large-scale laboratory gasification facility. This unit consists of a fuel hopper (120 litres; fuel feed rate 15 kg/hr), a pressurised fluidised bed reactor followed by a high-temperature filter and a secondary reactor, along with a steam generator. Air, steam, and carbon dioxide may be employed, with operational temperatures of 900 – 950°C for the reactor and the secondary reactor, and 500°C for the Inconel filters.
