METHOD AND APPARATUS FOR PROCESSING OF CARBON-CONTAINING FEED STOCK INTO GASIFICATION GAS

摘要

The invention relates to chemical technology and equipment, in particular to apparatuses of processing of solid household and industrial waste, as well as other carbon-containing feedstock into combustible gasification gas and methods for pyrolysis and downdraft gasification process.

主权项

1. A downdraft gasification method comprising the steps of
providing a loading mechanism trunk, providing a drying zone providing a plasticization zone providing a pyrolysis zone providing a combustion zone providing a reforming zone providing a slag discharge zone supplying feedstock, forcing said feedstock through said loading mechanism trunk as well as through each of said drying zone, pyrolysis zone, combustion zone, reforming zone and slag discharge zone with a loading mechanism that comprises an elongated loading mechanism trunk and a feedstock feeder, causing said feedstock being forced through said loading mechanism trunk to form a plug that substantially hermetically separates said drying zone, said plasticization zone, said pyrolysis zone, said combustion zone, said reforming zone and said slag discharge zone from the atmosphere; causing formation and separation of steam from said feedstock in said drying zone,
causing pyrolysis gases to form in said pyrolysis zone,separating substantially all of said pyrolysis gases from said feedstock in said pyrolysis zone, thereby causing separation of carbon char residue;and forming gasification gases;
