THERMOSELECT Comparison between High Temperature Gasification and Incineration During high temperature gasification – as is THERMOSELECT – waste is converted into a gaseous energy carrier (synthesis gas) at high temperatures and an oxygen deficiency. The organic substances are split into combustible compounds and the remaining carbon is converted into carbon monoxide. The process heat required is provided by partial oxidation of the organic waste constituents. Energetic utilisation The low calorie synthesis gas produced can be used in boilers for the purpose of heat production or in gas engines or turbines for electricity production or for the combined provision of heat and electricity. Material usage for chemical synthesis Optionally, pure hydrogen, methanol or other basic chemical materials can be obtained from this synthesis gas. THERMOSELECT: Thermoselect offers a modern and sustainable process of thermal treatment of waste, by which the organic part of the waste is transformed into synthesis gas and the inorganic fraction into mineral wool products. Incineration: Incineration offers a partial solution to the waste problem, since slags, ashes and filter dusts are left. Decisive advantages: THERMOSELECT • High temperature gasification with pure oxygen (process temperatures up to 2000°C) enables direct melting of the mineral and metallic waste components • Small volumes of synthesis gas to be treated as there is no nitrogen ballast. • Extremely low emissions from the process due to the high temperatures, oxygen free synthesis gas and shock cooling. • Conversion of synthesis gas into electric energy in modern gas turbines or fuel cells with high efficiencies • Production of basic chemical substances • Conversion of inorganic feedstock components into Mineral Wool for insulation purposes and plant breeding • Sustainable waste to energy. Waste incineration • When the waste is incinerated with significant excess air only temperatures of approx. 900°C are reached. Highly contaminated bottom and fly ashes are produced. • Large volumes of flue gas must be cleaned, which is expensive • Gradual cooling of the flue gases leads to the formation of dioxins and furans • Conversion into electric energy only possible with steam turbines, efficiency is inherently low • No valuable use of inorganics • The contaminated ashes and filter dusts must be expensively disposed.
