Definitions

  • the present invention relates to a coal gasification installation and more particularly using a gasification technique on a liquid metal bath.
  • the present invention aims to provide an installation for the production of high quality synthesis gas, with good efficiency in the use of coal.
  • a gasification plant for pulverized solid fuel of the type comprising a gasification reactor with a liquid metal bath, provided with at least one lance for introducing therein the pulverized solid fuel and a fuel gas, and a orifice for the evacuation of the gases produced, characterized in that it comprises, arranged in series starting from the outlet orifice of the reactor and traversed, in series, by the gases leaving the reactor: a chimney forming a boiler, a superheater of steam supplied from said boiler, a dedusted-.
  • the single figure is a schematic representation of the gasification installation according to the present invention.
  • This installation includes a coal gasification reactor 1 which is the subject of another patent application filed today.
  • This reactor 1 shown diagrammatically in section is of the bath type (2) of liquid iron, this bath being surmounted by a layer of slag (3).
  • the pulverized coal is injected with a flux containing lime and desulphurizing additives into the iron bath by means of a lance (4) from a conduit (5).
  • This same lance (4) thanks to a structure with cooled multiple envelopes (not shown) also serves for the injection of oxygen added with steam which is supplied by a conduit (6).
  • the reactor (1) is also provided at its upper part with a pipe (7) for introducing rock addition elements.
  • the reactor (1) is of the non-tilting type, but translatable and of large dimensions. Indeed, thanks to slides on which the reactor is mounted, it is possible to replace a new reactor with a used reactor, thus reducing to a minimum the shutdown of the gasification installation for repairing the reactor.
  • the reactor (1) is also provided with draining means making it possible to renew the metal which would have been polluted by non-volatile alloy metals, that is to drain it before translation.
  • the gases produced in the reactor (1) are discharged through an orifice (8) opening into a gas cooling chimney (9) described below according to the direction of flow of the gases.
  • This chimney (9) firstly comprises a direct pressure high-pressure boiler (9 A) of conical shape forming a hood, covering the orifice (8), then an ascending duct (10 A) and a descending duct (10 B), with double jacket which connects the boiler (9 A) to a steam superheater (11).
  • the gases from the reactor (1) therefore pass through the chimney (9) consisting of the three sections defined above in which they are cooled before entering the steam superheater.
  • the sections (10 A) and (10 B) of the chimney also function as a boiler thanks to a circulation of water in the double jacket.
  • the water circulating in the boiler (9 A) and the double envelopes of the conduits (10 A) and (10 B) is sent into a conventional separator tank not shown.
  • the combustible gases are sent via a line (12) into one (or more) cyclone (s) for dust collector (13).
  • the dusted gases from the cyclone (s) (13) pass through a heat exchanger (14), then are sent via a pipe (15) to a conditioning tower (16) into which a water mist is injected.
  • the gases are humidified and co-cooled with a descending water mist and extracted at the base of the tower to be sent to a dry electrostatic precipitator (17) by a pipe (18).
  • the dust collected in the cyclone (13), the conditioning tower (16) and the dry electrostatic precipitator (17) are stored in an evacuation hopper (19).
  • the purified combustible gases coming from the electrostatic precipitator (17) are sent, after saturation by spraying with water, not shown in a sheath arranged at the outlet of the electrostatic precipitator, into a gasometer (20) via a three-way valve (21) which ensures the possibility of rapidly sending gases to a flare (22).
  • the combustible gases stored in the gasometer (20), of the wet type, can then undergo an additional treatment which consists of an additional purification of the gases in a wet electrostatic precipitator (23), then in a compression in a compressor (24) and possibly in a final treatment for complete desulfurization (25).
  • the vapor separated in the separator tank not shown, is sent by a line (26) into the superheater (11) from where it is extracted by a line (27).
  • the vapor from this pipe (27) is sent on the one hand by a pipe (28), to a compressor (not shown) of the oxygen plant (29) which it drives, and on the other part, via a pipe (30) to the pipe (5) where it serves as a transport fluid for the pulverized coal feeding the lance (4).
  • the oxygen plant (29) supplies the lance with oxygen via the line (6) and also supplies nitrogen used as a drying fluid which is sent via a line (32) to a coal-mill-dryer ( 33).
  • This crusher-dryer is supplied with pulverized coal by a hopper (34) which is itself supplied from the homogenized stock of raw coal (35).
  • the dry pulverized coal from the mill-dryer (33) is sent to the intermediate storage hoppers (36) via a cyclone (37).
  • Powdered lime is also stored in a hopper (38), as well as additives such as Mn ore, dolomite, and possibly kiln dust containing zinc in a hopper (39).
  • the hoppers (36), (38), (39) constitute a supply battery for a mixer (40) which itself feeds intermediate silos (41) for weighing and adjusting the flow rate of pulverized coal which is sent into the pipe (5).
  • the slag from the layer (3) surmounting the melt (2) is granulated in a granulator (45) and stored in (46) or discharged in (47) towards its final use, for example as a cement clinker.
  • One of the defining characteristics of the present invention lies in the design of the various members making it possible to obtain an appropriate thermal cycle for cooling the combustible gases produced in the reactor (1) by gasification of coal.
  • the gases should be kept at temperature levels and during determined residence times.
  • Desulfurization is carried out during the cooling of the gases in the chimney (9) and as far as the heat exchanger (14), before the elimination by coalescence of the aerosols of sulfutres and metal oxysulfides in the conditioning tower (16).
  • Desulfurization is carried out by action on the gas produced in particular by gasification of coal, vapors in the form of aerosols of iron and / or manganese and / or zinc and / or their oxides according to a process described in another application filed this day by the plaintiff.
  • Further desulphurization with zinc can be carried out by injecting Zn vapors in the form of aerosols in the gas produced, at a point preferably situated at the outlet of the superheater (11) to the cyclone (13).
  • the devices for injecting Zn vapor in the form of aerosols have been schematically represented by the reference 70 in the single figure.
  • the gases coming from the reactor leave the latter at a temperature of approximately 1500 ° C., are first of all cooled to approximately 1450 ° C. at the outlet of the boiler (9 A) , then up to approximately 730-750 ° C at the inlet of the superheater (11).
  • the steam from the separator tank is superheated to around 400 ° C and discharged through line (27).
  • the gases are brought back to the temperature of approximately 620 ° C., then cooled to approximately 600 ° C., at the outlet of the cyclone (s) (13).
  • the gases exit the exchanger (14) at the temperature of approximately 380 ° C. after having brought the drying fluid (which is nitrogen) withdrawn by the line (32) to a temperature of 355 ° C. to 360 ° C approx.
  • the gases are then treated in the conditioning tower (16) with a water mist and extracted at the base of the latter at approximately 150 ° C., then sent to this temperature in the dry electrostatic precipitator (17), at the outlet. from which they are cooled to around 55 ° C by water saturation before being sent to the gasometer (20).
