Abstract: A gasification reactor with a heat exchange unit having a gas flow channel and one or more heat exchangers arranged within the gas flow channel, the heat exchangers having one or more heat exchange surfaces and one or more associated structures, such as a support structure or deflector plates. The associated structures are provided with fouling protection devices, such as blasters or flow guiding surfaces.

Abstract: Tubular wall assembly (8) comprising a plurality of tubular conduits (10) in parallel arrangement interconnected to form a gastight structure, each tubular conduit (10) being connected on one end to a common distributor (12) and on another end to a common header (11), wherein through each conduit a flow path extends between the distributor and the header, wherein each flow path crosses a passage opening in a seat (21, 28, 43) for an insertable flow restrictor (22, 44), wherein for each conduit the wall assembly comprises an opening (17, 51) bordered by a collar (15, 42) with an open end in line with the seat, wherein the open end of the collar is closed by a cap (26, 35, 49).
