A steam supply system comprises a steam source (10) for producing a supply of steam and a steam accumulator (30) for supplying accumulator steam to a steam load. The accumulator (30) is connected to said steam source for heat exchange and comprises a vessel (30) containing water under elevated pressure and temperature. Said vessel (30) has a footprint that is smaller than a height of said vessel relative to said foot print and comprises circulation means (50) that are connected between a lower section (31) of said vessel and an upper section (32) of said vessel, said upper section residing above a water level (35) inside said vessel. Said circulation means comprise at least one water pump (50) communicating upstream with said lower section (31) and downstream with water outlet means (55), opening in said upper section (32) of said vessel.

A burner (1) for combusting metal powder, particularly iron powder, comprising a combustion chamber (2) containing a combustion space for holding a combustion flame during operation, the combustion chamber having an air inlet (3), a metal powder inlet (4), and a exhaust gas outlet (5), characterized in that the combustion chamber (2) has a recirculation channel (7) for recirculating exhaust gases, the recirculation channel (7) being in communication with the combustion space within said combustion chamber (2), and the recirculation channel (7) intersecting with the air inlet (3).

Spray device as well as a method for manufacturing an spray device, comprises assembling at least one spray nozzle plate into a thermoplastic holder, while controlling the temperature of the spray nozzle plate and/or the holder and as a result at least locally plastically deforming the holder permanently. After the thermoplastic deformation of a seat of the holder, a diameter of the seat of the holder upstream of the spray nozzle plate exceeds a diameter of the seat of the holder downstream of the nozzle plate. The thermoplastic holder may have a tapered seat, where the smallest cross section of the tapered seat is smaller than the spray nozzle plate, wherein the method may comprise: - heating the spray nozzle plate; - pressing the spray nozzle plate into the tapered seat of the holder by bringing the nozzle plate towards a smallest side of the tapered seat, thereby thermoplastically deforming a wall of the tapered seat; and - forming a spray device from an assembly of the spray nozzle plate and the thermoplastic holder, whereas a widest side of the tapered seat is pointing towards a supply side of the liquid

A transport device comprises a frame (1) with a rolling chassis (2) on which is provided a loading floor (3) on which a load can be received. A roll-out stop which confines the load laterally inside the frame comprises at least one blocking arrangement (10) on a flank of the frame (1). The blocking arrangement comprises a blocking body (12) which is adjustable therein between a raised blocking position and a downward directed passage position. The blocking body (12) provides in the blocking position a stop surface (14) against which the load strikes in the lateral displacement, but allows this displacement out of the frame in the passage position. The blocking arrangement (10) comprises spring means, comprising at least one first spring (21), which urge the blocking body (12) to the blocking position under spring tension.

Because there is a need for larger rigs and there are many smaller rigs available that are no longer in use, a method converts a substructure of a wellbore rig for use with a larger mast. The substructure includes a floor and a bed laterally offset and lower than the floor, the method includes: installing a hydraulic cylinder lug on each side of the substructure below the bed, wherein each hydraulic cylinder lug includes a lug eye and the lug eyes are positioned below the bed; and installing lugs under the floor to receive a rotatable connection of mast rear legs. A rig transport package and a method for transporting the rig, including the converted substructure is also described.
