The invention relates to a method of manufacturing a front face () for a burner (), particularly for the gasification of solid carbonaceous materials by partial combustion. The front face () comprises a central aperture () corresponding to the discharge end of the burner, a front side wall () and a backside wall () spaced by one or more baffles () defining a coolant flow path with a coolant inlet () and a coolant outlet (). The front side wall () and the one or more baffles () are made of a single piece of metal and the backside wall () is welded on the free top ends of the one or more baffles. The front face can for example be made of a steel according to UNS N07718.

Method of manufacturing a burner front face

Disclosed is a removable cooling module (), for use in a reactor () for carrying out an exothermic reaction, comprising a coolant feed tube (); a distribution chamber (); a plurality of circulation tubes (); and a collection chamber (); said coolant feed tube () having at its first end an inlet (), for charging the coolant module () with coolant, and communicating with said distribution chamber () at its second end; each of said circulation tubes () communicating with the distribution chamber () through a first end and communicating with said collection chamber () through a second end; the collection chamber () having an outlet for discharging coolant. The modular nature of the invention facilitates removal of individual cooling module () from a reactor shell ().

Heat-exchanger for carrying out an exothermic reaction

A sparger system () for a reactor () includes a feed pipe arrangement for feeding reactants to the spargers on the floor of the reactor, via a distribution system disposed above the spargers. The outlets () of the spargers are typically oriented towards the floor or parallel to it in order to eject gas or other reactants across the floor. This reduces settling of catalyst on the floor of the reactor, which improves mixing of the slurry and reduces the problems associated with uncontrolled reactions.
