    • It is disclosed a system for feeding a ligno-cellulosic feedstock (50) to a pressurized vessel (200) having a vapor or gas phase of at least one fluid maintaining a vessel pressure greater than or equal to 1 bar. The pressurized vessel comprises a feedstock inlet (230), a feedstock outlet (220), a top and a bottom relative to the force of gravity, wherein the feedstock outlet is closer to the bottom of the pressurized vessel than the feedstock inlet. The feeding system further comprises a plug forming system (100) comprising a plug forming device (105) located in a plug forming chamber (130), the chamber having a first end (110B) and a second end (110A), said first end having a first end operating pressure which is lower than the vessel pressure and said second end being connected to the feedstock inlet and having a second end operating pressure which is greater than the first operating pressure. Said plug forming device is capable of receiving the ligno-cellulosic feedstock at the first end pressure; advancing the ligno-cellulosic feedstock through the plug forming chamber; and forming a plug from the ligno-cellulosic feedstock which prevents the passage of the vapor or gas phase from the pressurized vessel. The feeding system further comprises a sealing head located inside the pressurized vessel, which is movable at a seal opening speed between a sealing position located at the feedstock inlet and a rest position, wherein the sealing head in the sealing position isolates the pressurized vessel from the plug forming chamber. The seal opening speed is fast enough so that the sealing head disengages from the feedstock before or at the moment the sealing head reaches the rest position. The sealing head in the rest position is located at a distance far enough away from the feedstock inlet (sealing head) so that the feedstock entering the pressurized vessel does not contact the sealing head.
    • 公开了一种用于将木质纤维素原料(50)进料至具有保持容器压力大于或等于1巴的至少一种流体的蒸汽或气相的加压容器(200)的系统。 加压容器包括原料入口(230),原料出口(220),相对于重力的顶部和底部,其中原料出口比原料入口更靠近加压容器的底部。 所述进料系统还包括塞形成系统(100),其包括位于塞子形成室(130)中的塞子形成装置(105),所述腔室具有第一端(110B)和第二端(110A),所述第一端 具有低于容器压力的第一端操作压力,并且所述第二端连接到原料入口并且具有大于第一操作压力的第二端操作压力。 所述塞子形成装置能够在第一端部压力下接收木质纤维素原料; 推进木质纤维素原料通过塞子形成室; 并从木质纤维素原料形成塞子,其阻止蒸气或气相从加压容器通过。 进料系统还包括位于加压容器内部的密封头,其可以在位于原料入口处的密封位置和静止位置之间的密封打开速度下移动,其中密封位置中的密封头将加压容器与 塞形成室。 密封打开速度足够快,使得密封头在密封头到达静止位置之前或之时脱离原料。 处于静止位置的密封头位于距离原料入口(密封头)足够远的距离处,使得进入加压容器的原料不接触密封头。

    • 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.

    • The invention relates to a method for feeding of solid fuel into a process space (1) , such as a firebox, gas chamber or like, by means of a supply arrangement (2), which comprises an intermediate container (2c) that is to be opened and closed by feeding means (2a) and discharge means (2b) , whereby the level of the fuel (Pa) therein is being kept within set limits by feeding the fuel (Pa) into the intermediate container (2c) by using the feeding means (2a) , when the intermediate container is kept closed by means of the discharge means (2b) . The fuel is being discharged from the intermediate container by using the discharge means (2b) for bringing the fuel into the process space (1),' when the intermediate container is kept closed by the feeding means (2a) . A flow of process gas taking place from the process space (1) to the surroundings through the supply arrangement ( 2 ) for fuel is being prevented by pressurizing the intermediate container (2c) at a pressure that is essentially higher that the pressure in the process space (1) and by feeding the solid fuel (Pa) into the process space (1) by means of a transport conveyor (2bl) , which brings about a counter pressure with respect to the combustion process, and a discharge apparatus (2b2) of open-shut -type, both of the above belonging to the discharge means (2b) . The invention relates also to a supply arrangement operating according to the method.
