One of the residual gas flows of this resin manufacturer contains hydrogen, carbon monoxide and various hydrocarbons. We cleverly put this low-calorific residual gas flow to good use by turning it into fuel for a double-flame steam boiler with steam super-heater. In spite of the residual gas’s low calorific value (2100 kJ/Nm3 LHV) we managed to create a heating process without support fuel. What’s more, we executed the heating process using a special burner concept: the stabilising chamber.
