Definitions

  • the present invention relates to a reactor for carrying out a partial oxidation process of a finely divided solid carbon-containing fuel and an oxidant.
  • Finely divided solid carbon-containing fuels are applied in processes for the preparation of synthesis gas by the partial combustion of a finely divided solid carbon-containing fuel with an oxygen-containing gas in a reactor wherein liquid slag formed during the partial combustion process is removed through an outlet in the bottom of the reactor and passed by gravity through a slag discharge means into a water bath or slag quenching vessel where it is solidified by quenching.
  • finely divided solid carbon-containing fuel is generally meant coal or another solid fuel, such as brown coal, peat, wood, coke, soot etc., but mixtures of liquid or gas and particulate solid fuels, are also possible.
  • a moderator is also introduced into the reactor.
  • the object of the moderator is to exercise a moderating effect on the temperature on the reactor. This is ensured by endothermic reaction between the moderator and the reactants and/or products of the synthesis gas preparation.
  • Suitable moderators are steam and carbon dioxide.
  • the gasification is advantageously carried out at a temperature in the range from 1200 to 1700 °C and at a pressure in the range from 1 to 200 bar.
  • the reactor in which the preparation of synthesis gas takes place may have any suitable shape.
  • the supply of finely divided solid carbon-­containing fuel and oxygen-containing gas to the reactor can take place in any manner suitable for the purpose and will not be described in detail.
  • Liquid slag formed in the partial combustion reaction drops down and is drained through the outlet located in the reactor bottom.
  • the fuel is fed from a supply device to a gasifier by means of a suitable carrier fluid.
  • the hot product gas usually contains sticky particles which lose their stickiness upon cooling.
  • the sticky particles in the hot product gas will cause problems in the plant where the product gas is further processed, since undesirable deposits of the particles on, for example, walls, valves or outlets will adversely affect the process. Moreover, such deposits are very hard to remove.
  • the sticky particles may be partly or completely in the molten state; they may comprise metals, salts or ashes, and, in general, these particles lose their stickiness at a temperature below about 800 °C.
  • the hot product gas is quenched in a quench section which is located above the product outlet on top of the reactor.
  • a suitable quench medium such as for example water or a gas is introduced into the product gas in order to cool the product gas.
  • the invention therefore provides a reactor for carrying out a partial oxidation process of a finely divided solid carbon-containing fuel and an oxidant, said reactor comprising a reactor vessel having an outlet for the product gas at its top, a slag outlet at its bottom, a plurality of burner openings in its side wall, a plurality of tangentially directed burners located on the same horizontal level at circumferential spaced points, with a small firing angle, the reactor being provided with a quench above its outlet, wherein a stack having a predetermined length-to-diameter ratio is located between the reactor outlet and the quench inlet.
  • firing angle is defined as the angle between the symmetry axis of the burner jet and the line through the centre of the burner and the centre of the reactor at the same horizontal level.
  • a reactor vessel 1 has been shown.
  • the reactor vessel 1 is provided with a slag outlet 2 at its bottom, a plurality of tangenti­ally fired burners 3, a gas outlet 4 at its top and a quench system 5 comprising a quench inlet 5a above the reactor outlet 4.
  • the tangentially directed burners 3 are located on the same horizontal level at circum­ferental spaced points and cause vortex flow in the reactor vessel 1.
  • the quench system 5 is at its outlet 6 connected to equipment for further treating the synthesis gas. Such equipment is known to those skilled in the art and will not be described in detail.
  • equipment for further treating the synthesis gas.
  • Such equipment is known to those skilled in the art and will not be described in detail.
  • fig. 2 the same reference numerals have been used as in fig. 1.
  • the reactor 1 is provided with an extended pipe or stack 4a at its outlet 4. This extension is located between the reactor outlet 4 and the quench inlet 5a and has a predetermined length-to-diameter ratio Ls/Ds.
  • the quench system 5 is located remote from the reactor outlet.
  • Ls/Ds is 4 to 6 and more in particular Lq/Dq is 5 (as shown in fig. 2).
  • Fig. 3a represents a tangential burner arrangement comprising 4 burners A, B, C, D.
  • the burners are arranged horizontally and are directed to a central point E, which means that the firing angles are 0 degrees.
  • Fig. 3b represents a tangential burner arrangement of the invention comprising 4 burners A′, B′, C′, D′ wherein the firing angles are 5 degrees.
  • the firing angles according to the present invention are in the range of 3 to 5 degrees.
  • the burners are directed to a central circle E′ having a determined area.
  • the stack will also reduce the turbulence of the syngas. This reduction and the fact that the stack wall immediately below the quench inlet is vertical and thus much steeper than the reactor roof in fig. 1 will be beneficial to prevent slag lifting or slag entrainment.
