摘要： The feed duct (1) for a straw firing furnace comprises a slide valve (10) with a valve member (13) for closing the duct, a sprinkler (21) in a wall of the duct upstream of the slide valve, a water supply pipe (22) for the sprinkler, and means (14) for control and activation of the opening and closing of the valve member. The sprinker (2) is positioned close to the valve member and adapted to sprinkle said valve member by water, and the bottom (23) of the housing (12) of the slide valve (10) is positioned lower than the bottom (9) of the feed duct and is provided with drain openings (24) for draining off water supplied through the sprinkler.

摘要： An elongate cleaner member (32) is at the top suspended at the uppermost end of the side of each duct wall swept by combustion gases in a multi-duct heat exchanger. The cleaner member extends throughout the height of the duct (l2) without physical contact with the wall, and extends a distance down into lower chamber (ll). To the lowermost part of the cleaner member there is secured a deflector element (36) having asymmetrical mass and area distribution in relation to the point of interconnection between the deflector element and the cleaner member. In a preferred embodiment the cleaner member (32) consists of a chain with links (34, 35) having various widths; the chain links (35) in lower chamber (ll) being smaller than the largest (34) of the links lying between the ends of the duct.
Due to the influence on the deflector element from the combustion gas flow in the lower chamber the whole chain will perform a combined motion comprising an undulating movement with hortizontal amplitudes and a twisting motion forth and back about the vertical axis of the cain. This combined motion influences the gas flow along the duct wall and prevents particulate material entrained with the combustion gas flow from depositing on the wall.摘要翻译： 细长的清洁器构件（32）位于顶部，其悬挂在由多管道热交换器中的燃烧气体扫掠的每个管道壁的侧面的最上端。 清洁器构件在管道（12）的整个高度处延伸，而不与壁物理接触，并且向下延伸到下室（11）中。 在清洁器构件的最下部，固定有相对于偏转元件和清洁器构件之间的互连点具有不对称质量和面积分布的偏转元件（36）。 在优选实施例中，清洁器构件（32）由具有各种宽度的连杆（34,35）的链构成; 下室（11）中的链节（35）小于位于管道端部之间的最大（34）的连杆。 由于来自下腔室中的燃烧气体流动的偏转元件的影响，整个链条将执行组合运动，该组合运动包括具有水平振幅的起伏运动和围绕吸力的垂直轴线向前和向后的扭转运动。 这种组合运动影响沿着管道壁的气流，并且防止夹带有燃烧气体流的颗粒物质沉积在壁上。

摘要： By the process the supplied amounts of primary air and/or fuel are reduced in a definite way under and shortly after the vibration of the vibrating grate, whereby a sudden increase of the combustion rate caused by the vibration is avoided. As a result the sudden drops of the oxygen content of the exhaust gas occurring in common boilers are avoided, said drops being caused by the fact that the common fuel control reacts too slowly on sudden changes in the combustion conditions.

摘要： By the method bales of straw (4) are conveyed towards two parallel, rotatable solids of rotation (30), each of which carries a helicoid (31). The straw is loosened and transported away by the helicoid passing through or scraping over the area of the bale of straw facing the solids of rotation in the transport direction of the helicoid. When compacted lumps of straw are jammed between the bale of straw and the solids of rotation, the solids of rotation are swung away from the bale of straw to allow further conveyance.

摘要： The boiler comprises a roof and two side walls (22, 25) formed as membrane walls each having a lower header (23, 26) at the bottom and being connected at the top with at least one upper header (27). The boiler has at least one suspended heating surface section comprising several heating surface tubes (30) supported at the top and passed from the roof down to lower headers lying crosswise in the boiler. The roof in the boiler is a membrane wall (28), and the heating surface tubes extend uninterruptedly from one lower header up through and above the roof and return through the roof to an adjacent lower header, and have been passed in a gastight and longitudinally displaceable manner through the membrane wall of the roof.

摘要： The convection cooler comprises an oblong vertically positioned pressure vessel (1) with an upper gas inlet (5) and a lower gas outlet (8) and the vessel accomodates a heat exchange element (10) with heat exchange surfaces (11) for flow of water and steam under high pressure. The heat exchange surfaces define gas ducts (12) divided into straight sections (13) connected with short duct sections (14) which, when viewed in the direction of the gas flow, slope towards the bottom of the vessel. Adjacent duct sections (13) are displaced in the lateral direction at a distance corresponding to the width of the duct. This change in direction of the duct causes the gas flow to be thoroughly mixed during passing, resulting in a uniform distribution of the temperature across the entire cross-sectional area of the duct. At their top the heat exchange surfaces (11) have a common discharge header (18) which through suspensions (19) are suspended at the top of the vessel so that the full load of the heat exchange element (10) is carried by the discharge header (18).

摘要： The radiation cooler comprises an oblong vertically positioned pressure vessel (1) with a heat exchange element including two sections (10, 11) constituting a central gas passage (12) and a peripheral gas passage (14). For the further cooling of gas and slag there is a second, central heat exchange element (15) positioned in the lowermost portion of the central gas passage (12) and a third heat exchange element (16) positioned in the uppermost portion of the peripheral gas passage (13). The tubes from the second heat exchange element (15) merge directly into the tubes forming the third heat exchange element (16) and both of the heat exchange elements are divided into vertical plane panels (15a, 16a). The tubes forming the heat exchange surfaces (10, 11, 15a, 16a) extend vertically and are welded together to form membrane walls. The heat exchange elements are supported by a common discharge header (20) at the top of the vessel, thereby avoiding supplementary, internal stiffening during transportation of the vessel in a horizontal position as well as during operation in a vertical position. This facilitates also the removal of all the heat exchange elements as a unit upon overhaul.

摘要： Le refroidisseur de gaz à rayonnement décrit comprend un récipient sous pression disposé verticalement et de forme oblongue (1) comportant un élément d'échange thermique contenant deux sections (10, 11) qui forment un passage de gaz central (12) et un passage de gaz périphérique (14). Pour le refroidissement ultérieur des gaz et du laitier sont prévus un deuxième élément d'échange thermique central (15), placé dans la partie inférieure du passage de gaz central (12), et un troisième élément d'échange thermique (16) placé dans la partie supérieure du passage de gaz périphérique (13). Les tubes partant du deuxième élément d'échange thermique (15) se rejoignent directement dans les tubes formant le troisième élément d'échange thermique (16) et les deux éléments d'échange thermique sont divisés en panneaux à plan vertical (15a, 16a). Les tubes formant les surfaces d'échange thermique (10, 11, 15a, 16a) s'étendent verticalement et sont soudés ensemble pour former des parois à membranes. Les éléments d'échange thermique sont tenus par un collecteur de décharge commun (20) situé au sommet du récipient, ce qui permet d'éviter toute rigidification interne supplémentaire pendant le transport du récipient dans une position verticale et pendant son fonctionnement dans une position verticale, tout en facilitant également le démontage de tous les éléments d'échange thermique en une seule unité lors des travaux de remise en état.
