US 2015/0027038 A1 · PROCESS AND APPARATUS FOR BRIQUETTE PRODUCTION

Abstract

Process for producing a briquette containing carbon carriers (2): mixing the carbon carriers (2) together with a binder system (3) with introduction of steam and the mixture obtained is pressed to form briquettes. At least one of drying carbon carriers (2), setting the temperature of the carbon carriers (2) to be mixed with the binder system before mixing or heat treating the briquettes after pressing by direct or indirect interaction with superheated steam. Waste steam is at least part of the steam introduced during mixing. An apparatus for carrying out such a process has such interaction with steam, from which a waste steam conduit leads and opens directly or indirectly into the mixing device.

Dependent claims

A process for producing a briquette containing carbon carriers comprising:

mixing the carbon carriers together with a binder system and with the introduction of steam;
pressing the mixture obtained to form briquettes,
performing at least one step selected from the group consisting of
drying the carbon carriers before mixing,
setting the temperature of the carbon carriers to be mixed with the binder system before mixing in a predefined temperature range,
heat treating of the briquettes after the pressing,
wherein
the drying of the carbon carriers before mixing, and/or
the heat treating of the briquettes after pressing, and/or
the setting of the temperature of the carbon carriers to be mixed with the binder system before mixing in a predefined temperature range,
are performed by means of direct or indirect interaction with superheated steam.

8 more elements

An apparatus for producing a briquette containing carbon carriers, comprising

a mixing mechanism configured and operable for mixing carbon carriers with a binder system for the briquette;
the mixing mechanism comprising a steam supply conduit for supplying steam:
a pressing mechanism configured and operable for receiving and a mixture obtained from the mixing mechanism and for pressing briquettes on the basis
at least one member of the group consisting of
a dryer before the mixing mechanism for drying the carbon carriers,
a heat treatment apparatus for heat treatment of the briquettes during and/or after the pressing by the pressing mechanism,
and apparatus configured and operable for changing the temperature of the carbon carriers before their entry into the mixing mechanism,
wherein
the dryer, and/or
the apparatus for changing the temperature of the carbon carriers before entry into the mixing mechanism and/or
the heat treatment apparatus for heat treatment of the briquettes comprises an apparatus configured and operable for direct or indirect interaction with steam, having a steam-feeder conduit for feeding steam therein and a waste-steam conduit therefrom and the waste-steam conduit opens into the steam supply conduit and/or into the mixing mechanism.
