Flameless gasification of coals and oil shales offers great opportunities for the production

Raw materials
According to the proposed technology, a wide range of energy fossil raw materials, such as coal, oil shale, peat and many other, may be subjected to processing on the Flameless Gasification complex.

PRODUCTION PROCESS
main stages (by the example of coal)

PREPROCESS


OPEN-CUT COAL MINING


MINING METHOD OF COAL PRODUCTION

PREPARATION AND FEEDING OF RAW MATERIALS INTO FLAMELESS GASIFICATION COMPLEX


FEEDING RAW MATERIAL INTO THE FLAMELESS GASIFICATION UNIT
Having passed the sorting and grinding stage (to the required parameters) the raw material proceeds from the industrial site to the Flameless Gasification block for production of syngas.


FROM THE HOPPER THE RAW MATERIAL IS DELIVERED BY SCREW CONVEYER INTO THE GASIFICATION UNIT

PROCESSING OF THE INCOMING RAW MATERIALS BY THERMOLYSIS METHOD


GASIFICATION OF THE INCOMING RAW MATERIALS


FOUR STAGES OF GAS CLEANING AFTER GASIFICATION PROCESS

Syngas

 

Syngas is the main product of the processing of coals and oil shale in the Flameless Gasification complex.
In its turn the syngas becomes the raw material for the production of highly demanded marketable products.

CONCEPT
proposal for the introduction of flameless gasification technology

Extracted by open-cut and mining methods coal and oil shale, under the proposed process chain, are subject to Flameless Gasification, for the purpose of production of syngas, suitable for the generation of considerable quantities of electricity and heat, as well as for the production of various kinds of chemical products, including methanol, ethylene propylene, fertilizer, hydrogen or motor fuel.
