The tensioning device (3) includes a cylinder (4) inserted into the oven wall, a hollow piston (7) guided therein and a spring (26), which can be adjusted in its tension. The grate side plate has a carrying plate (12) directly fastened to the piston bottom (10) with a grate border plate (13) suspended, or hanging, on the carrying plate (12). The piston (7) has diameter and length dimensions such that it can support and guide the grate side plate without further guiding devices. Neighboring pistons (7) are connected flexibly to each other by guiding bars (36), so that the pistons (7) can influence each other reciprocally. An upper edge of the grate side plate, particularly the grate border plate (13), has a flange (17) extending toward the oven wall. The flange (17) sealingly engages an elastical seal (19), fastened onto the oven wall.

Title: Method for the reduction of n2o separation in the combustion of nitrogen-containing substances in fluidized bed reactors
Inventor: HILTUNEN MATTI
IPC: F23J15/08
Filed: 1992-11-16
Abstract: The amount of N2O emission from a fluidized bed reactor is reduced by adding a hydrogen radical providing additive (e.g. a hydrogen containing fuel such as natural gas or alcohol) to the flue gases discharged from the fluidized bed. Sufficient oxygen is present in the flue gases-either by addition with the additive, or by addition of an excess to the combustion chamber-so that the additive reacts with the oxygen, typically raising the temperature of the flue gases (e.g. from about 700 DEG -900 DEG  C. to about 950 DEG -1100 DEG  C.) so that N2O production is reduced about 10-90%. The additive may be injected in or just prior to a cyclone for separating particles from the flue gases. In a gas discharge immediately after the cyclone, just prior to a superheater of a convection section, or in a combustion chamber just prior to a gas turbine.

Abstract: Es wird eine Ankerhemmung umfassend einen Anker (Ab) und ein Ankerrad (2) für ein mechanisches Uhrwerk offenbart, bei denen erfindungsgemäss federnde Elemente (4b) vorhanden sind für eine gefederte Berührungsaufnahme und Berührungsabgabe zwischen Ankerpaletten (4b) und Ankerradstiften (3). Die federnden Elemente (4b) sind durch Ankerpaletten ausgeführt, die aus federndem Material gefertigt sind. Bei der Berührung zwischen der Ankerpalette (4b) und einem Ankerradstift (3) und beim Anhalten des Ankerrads (2) bewirken die federnden Elemente (4b) eine Umwandlung und Speicherung von kinetischer Energie des Ankerrads (2) in Federenergie, die beim Verlassen des Ankerradstifts (3) wieder an den Anker (Ab) abgegeben wird und der Anker (Aa) einen Impuls erhält. Weitere Ausführungen enthalten federnd ausgeführte Ankerstifte oder Federn an drehbaren Ankerpaletten. Die Erfindung bewirkt eine Reduktion der benötigten Antriebsenergie und mechanischen Belastung aller beweglichen Komponenten einer Uhr. Bei kleinen Uhren erhöht sich die Laufzeit, bei Grossuhren sind die Kräfte am Anker (Aa), am Ankerrad (2) sowie im gesamten Räderwerk reduziert.
