Definitions

  • This invention relates to burners for the partial oxidation of a particulate fuel, for example to a burner for introducing a combustible mixture comprising hydrocarbon fuel, free oxygen-containing gas, and optionally a temperature moderator (liquid or vapor) into a free-flow partial oxidation synthesis gas generator.
  • the oxidizing flame which combusts the mixture introduces the hot flame as well as the products of combustion into a generator such as the reaction chamber of a synthesis gas generator.
  • a generator such as the reaction chamber of a synthesis gas generator.
  • the latter is lined with a suitable refractory material to avoid damage as a result of the high temperatures that will be reached and sustained.
  • a relatively vulnerable part of the burner is that portion which is continuously exposed for extended periods of time to the high reactor temperatures. Although means have been provided for cooling internal portions of the burner, the problems which result from the high temperature still persist.
  • external walls of the burner are generally surrounded with a cooling coil or the like which circulates a liquid such as water to effectuate a cooling action.
  • a cooling coil or the like which circulates a liquid such as water to effectuate a cooling action.
  • the lower or flame. end of the burner is provided with internal passages which permit coolant to be internally circulated to maintain a desired temperature range.
  • the forward most vulnerable face of the burner can reach certain temperatures, or range of temperatures, within which accumulations of particulate slag or ash will tend to cling to the exposed burner face. Such a slag build-up will cause a reduction in burn efficiency and eventually impairment of operation and eventual unit shutdown.
  • One way for precluding or at least limiting this slag build-up along the burner face is to inject steam directly into the combustible mixture within the burner itself. This step will facilitate the avoidance of undesired build-ups at the discharge lip. It will not, however, completely preclude the accumulations as herein mentioned.
  • the back mixing and flow of the particulate matter as a result of the turbulence immediately inside the reactor will continue to cause or prompt a certain degree of build-up at the burner face.
  • An object of the present invention is to achieve progress towards overcoming the above stated problems of slag build-up along the burner face.
  • a burner for the partial oxidation of a particulate fuel to form a gaseous product characterised by:
  • the pressurized stream of fluid serves to provide a fluid dynamic shield which protects the entire burner face.
  • a number of fluids such as steam, C0 2 or even water could serve as the protective dynamic shield.
  • the fluid will be considered to be steam.
  • One or more high velocity steam jets may be caused to sweep the burner face.
  • the jets first of all form a barrier which precludes the hot par- tides from approaching and contacting the face.
  • the fluid jet is so aligned that it will flow parallel to the face, or will contact or impinge against the face preferably adjacent to the discharge lip. This creates a thermal radiation/con- vection shield to keep the burner face below 400° to 500°C.
  • the flow will clear the face of any accumulation that might be initiated.
  • FIG. 1 and 2 One embodiment of a partial oxidation apparatus is shown in Figures 1 and 2 and comprises primarily a burner 10. The latter is connected to a source of oxygen 11 as well as to a source 12 of particulate hydrocarbon fuel such as a coal slurry or the like. Thus the two components when introduced to the burner will form a combustible mixture.
  • the apparatus is subjected to sustained high internal temperatures and is formed basically of a steel shell.
  • the inner walls and openings of the shell while not specifically shown here, are so constructed and lined with a refractory material that they will withstand the harsh environment.
  • the discharge end 13 of burner 10 is positioned to introduce the resulting flame as well as the products of combustion into refractory lined reactor 14. In the latter, the hot products of the partial combustion are collected.
  • Reactor or generator 14 is provided with a refractory lined opening 16 within which burner 10 is positioned.
  • Said opening 16 as shown includes a neck 17 which surrounds the burner to provide a degree of protection thereto.
  • the upper end of the burner 10 is provided with a flange 18. which mates with a support flange 19. The latter projects outwardly from reactor neck 17 to hold the burner 10 in place, and yet permit its ready removal for replacement or repair.
  • Burner 10 comprises an elongate body 21 (Figure 2) having a longitudinal passage which extends the length of the body 21.
  • the lower end of said passage terminates at a constricted.
  • cylindrical opening 22 which is defined by a peripheral lip 23 at the burner face 24.

  • Annular passage 29 communicates with the source 12 of coal slurry (and optionally a temperature moderator), by way of a valved conduit 31 for introduction of the fuel into the mixing compartment 26.
  • a valve 33 in conduit 31 regulates the volume flow rate of particulate or finely ground coal mixture which is introduced from source 12 for combining with the oxygen to establish the desired combustible mixture in mixing compartment 26.
  • the lower face 24 of burner body 21 as herein noted is normally exposed to the maximum temperature and turbulent environment experienced within reactor 14.
  • Said lower face 24 is normally formed of a heat resistant material such as Inconnel or the like which will be capable of functioning in spite of the high temperatures to which it is constantly exposed.

  • the steam preferably traverses across burner face 24 in a substantially uninterrupted pattern.
  • the steam will achieve at least two functions. Firstly, the steam will define a dynamic curtain or barrier across the burner face 24 to substantially preclude slag or ash particles from contacting the face. Secondly, the velocity of the steam will be such that it will dislodge any solid accumulation which might be initiated at lip 23. Thirdly, the disposition of the jet will be such as to provide a thermal radiation shield.
  • the volume of steam which leaves constricted opening 42 will be regulated to avoid adversely affecting production of a partially oxidized product.
  • manifold 37 is connected directly to, and depends from the peripheral forward end of burner body 21.
  • the manifold 37 provides an annular arrangement which can be either welded or otherwise fastened in place to extend slightly forward of the burner face 24.

  • the torus-like manifold is adapted to slidably register the forward end of burner 10 and to properly position face 24 with respect to constricted opening 42 thereby permitting the steam jet from the latter to sweep across face 24.
  • the burner 10 can comprise an arrangement similar to that shown in Figure 2.
  • manifold 37 can be provided with a plurality of discrete constricted openings 43.
  • the latter as shown define a plurality of passages, each of which is communicated with the manifold chamber 37 to receive the pressurized fluid.

  • Openings.43 can further be constructed as to provide the issuing steam with a particular configuration.
  • the openings may be formed by replaceable nozzles in a wall of the manifold.
  • the configuration can be substantially in the form of an fan-like flow to best provide the desired overlapping coverage across the face of burner 24.
  • the plurality of streams will be directed substantially parallel to face 24 to form the barrier and achieve the above noted two functions, i.e. providing a shield, and also keeping the face clear of solid matter.
  • the manifold can be provided with a single constricted opening as shown in Figure 2, or with a plurality of circularly arranged and spaced apart constricted openings as shown in Figure 3.
  • the stream directing openings can be spaced downwardly from face 24 rather than positioned immediately contiguously therewith.
  • the dynamic barrier or shield forming steam will be directed upwardly from the spaced apart openings and toward face 24.
  • the focus of the steam jets in this instance witt be at the discharge lip 43. Fine particulate ash or slag will thereby be caught up into the steam jet and carried away from face 24. Further, any solid material that does engage or cling to lip 23 will be dislodged and swept away by the steam impinged thereagainst.
