Benefits of technology

[0008]Another object of this invention is to let the smooth transfer between modes without interrupting the process. Therefore energy, labor and time saving is realized via the invented gasifier and the gasification method.
[0010]Another object of this invention is to obtain a gasifier and a gasification method which prevent the solidification of feedstock and clinker formation within the reactor and provides continuous gas production.
[0017]b) Incineration forms complex molecules containing poisonous materials such as dioxins and furans. Whereas gasification transforms complex molecules into gases with simpler molecule formation and prevents the formation of poisonous compounds such as dioxins and furans.

Problems solved by technology

However, it is not possible to switch from one mode to another without shutting down the process.
However, it is not easy to maintain the inside temperature at a fixed rate with this circulating bed gasifier.
Since the reduction reactions will not be regulated, sudden changes in gas output will be very high.
During the suction of the gas, partially un-processed feedstock will come out along with and the pyrolytic operation will not be proper.
In addition to that, since the unprocessed feedstock will leak from the gasifier, full process may not be realized.

Abstract

This invention is related to a gasifier and gasification methods realized in said gasifier to provide modular solutions at geographical areas where the access is difficult by processing the refuse-derived-fuel (RDF) obtained from waste including hazardous, industrial and municipal waste in an environmentally sound manner. Switching between the updraft and downdraft gasification modes in said gasifier is possible without the interruption of the system. Therefore energy, labor and time saving is realized via the invented gasifier and the gasification method.

Description

[0001]This invention is related to a gasifier which is used to recover gas from waste by thermally processing the waste and is also related to gasification methods using this gasifier. Specifically, this invention is related to gasification methods realized using this gasifier in which switching between downdraft and updraft modes can be realized without any interruptions according to the feedstock material introduced and the gas recovered, for which the gasification realized under vacuum conditions with high efficiency.[0002]In prior art, downdraft and updraft gasifies were used for waste gasification. Either downdraft gasifiers or updraft gasifiers or even the up / downdraft gasifiers are used. However, it is not possible to switch from one mode to another without shutting down the process.[0003]In prior art, WO2005 / 047435 discloses an up / downdraft gasifier. However this reference does not include any disclosure regarding the smooth switching between the systems without interrupting...
