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.
