Embodiment Construction

[0078] figure 1 An exploded view of the components of a first embodiment of a piston member 1 according to the invention suitable for delivering material to a receiver (not shown) is shown.

[0079] The piston member 1 consists of a proximal end cap 2, a piston 3 with a piston rod 4, a piston barrel 5, a tubular pressurized chamber cylinder 6, a T-shaped coupling cylinder part 7, a sealing ring 8 and an outlet tube 9 with a flange 10 . The overall cylinder available for the stroke of the piston consists of the piston cylinder 5, the tubular pressurized chamber cylinder 6 and the T-shaped coupling cylinder part 7, wherein the T-shaped coupling cylinder part 7 forms the distal end of the overall cylinder .

[0080] The proximal end cap 2 has a first coupling flange 11 for coupling with a corresponding first coupling flange 12 a on the piston cylinder 5 . The piston cylinder 5 has a second coupling flange 12 b opposite to the first coupling flange 12 a for coupling with the co...

Abstract

A piston member (1,1',1'') comprising a piston rod (4) provided with a piston (3,3',3'') serves for reciprocating inside a cylinder barrel (5,6,7,5',6',7',5'',6'',7''), said piston (3,3',3'') divides the cylinder barrel chamber (34a,34a',34a'',34b,34b',34b'') into a proximal cylinder barrel chamber (34a,34a',34a'') having a proximal capped end (35a,35a',35a'') opposite the piston (3,3',3'') and a distal cylinder barrel chamber (34b,34b',34b'') having a distal cylinder barrel end (35b,35b',35b'') opposite the piston (3,3',3''). The piston member comprises at least one sealing ring (8,8',8'') or seat arranged inside the distal cylinder barrel chamber (34b,34b',34b'') at the distal cylinder barrel end (35b,35b',45''). Preferably three consecutive piston members (1,1',1'') are arranged to operate in a series in an apparatus for transporting coal powder to a gasifier. The movement of the pistons inside the cylinder barrels is controlled in relation to each other to transport apportioned batches of coal powder to a high pressure reactor.

Description

technical field [0001] The invention relates to a piston member comprising a piston rod provided with a piston reciprocating within a cylinder, the piston dividing the cylinder cavity into a proximal cylinder cavity having a proximal capping end opposite the piston and a distal cylinder chamber having a distal cylinder end opposite the piston. [0002] The invention also relates to an apparatus for the continuous transport of dispensed batches of material to a receiver, such as a gasifier or a reactor. [0003] The invention also relates to methods of continuously transporting dispensed batches of material under high pressure to a receiver such as a gasifier or reactor. [0004] In particular, the invention relates to the use of apparatus and methods for transporting coal dust and other solid materials. Background technique [0005] Gasification of fossil fuels, biomass or waste is currently widely used on an industrial scale for power generation. Gasification relies on c...
