Principle of a HTCW Gasification Furnace

HTCW Reactor Diagram

Input waste materials and additional materials (coke, limestone and others as required) at normal pressure and the following temperatures:

100 to 200C:
Drying of input; elimination of physical water

250C:
De-oxidation; de-sulphuration; elimination of constituents like water and CO2; depolymerization; beginning elimination of H2S

340C:
Cracking of aliphatical bonds; beginning separation of CH4 and other aliphates

380C:
Carbonization

400C:
Break-up of C-O and C-N-bonds; separation of heteroatoms

400-600C:
Conversion of bitumen into smoldering oil and smoldering tar

600C:
Cracking of bitumen into thermally stable substances (short chained, gaseous hydrocarbons); synthesis of aromatic hydrocarbons

800-1,200C
Gasification: Synthesis of N2/NH3 and H2S/COS. Halogens are completely in vapour state (as alkalichloride or HCl) Melts: Synthesis of mineral melting phases

1,200-2,000C
Complete decomposition of aromatic hydrocarbons, HCN and organic chlorine compounds; formation of carbon black Melts: Synthesis of iron metallic melting phases

2,000C-2,700C
Beginning of molecular dissociation; lower plasma region
