Core Technology

The SK 1000 system is the standard reactor unit of the INC/OE Gasification core technology. It is a two-stage gasification process that converts sorted solid waste and biomass into a clean, inert “syngas” for thermal sinks to produce steam for industrial process and hot water for heating applications.

The SK 1000 is a standard unit that can process between 3,500 and 7,500 metric tons of solid waste per year, depending on the waste characteristics. The energy output is typically between 1.5 and 2.5 MW (thermal). Multiple units can be linked together to increase the volume of waste converted and the energy output produced.


Process Detail



1. Fuel Input

The SK 1000 accepts a variable fuel mix.


2. Gasification

Solid fuel is fed into the Primary (Gasification) Chamber, where the gasification takes place. The solids-to-gas conversion process in the primary chamber has three stages – drying, pyrolysis and gasification – where temperature and air mix are carefully controlled.

The air supply to the primary chamber is automatically controlled through a PLC to achieve gasification. The bottom ash from the primary chamber is automatically removed and collected in the bottom ash handling system. The ongoing gasification process is fueled by the glowing ash from the solid waste fuel in the bottom of the primary chamber. Hence, no external energy is required after start-up.


3. Combustion

The low-calorific gas produced in the primary chamber flows into the Secondary Chamber where secondary air is added to support the complete combustion of the flue gas.

The combustible syngas that is produced in the primary chamber can be used for several energy generation purposes. The syngas is "cleaned" by combustion in the secondary chamber and a particle separation process in the cyclone. The inert flue gas, at approx. 950ºC (1740ºF), is ducted to the boiler.


4. "The Cyclone"

The gas then flows into the cyclone-shaped Tertiary Chamber where remaining unburned fractions are completely burned out, and any remaining heavy particles in the flue gas are separated out as fly ash.

Hot water or steam is recovered from the flue gas leaving the cyclone to be used for industrial or heating applications. Leaving the cyclone, the hot flue gas is cooled down in the boiler where either hot water or steam is generated for industrial processes or heating applications.


The emissions standards are well within the EU 2000 guidelines.
This gasification of bio mass and sorted waste is considered a CO2 neutral process. Therefore, energy users who replace their current fossil-fuel burning system with gasification of organic and sorted waste, will qualify for "green" credits.
