Device for coke oven chamber pushing low in heat exchange

Abstract

A device for pushing the contents of a coke oven chamber includes a pusher ram head with pusher rams mounted there behind, wherein guiding plates or aprons are mounted to a pusher ram head which avoid a simultaneous pressing-in of air into the coke oven chamber, thus preventing a non-desired cooling-off of the coke oven chamber during pushing. The aprons also prevent the pusher ram and the rearward side of the pusher ram head from excessive heat burdens. The aprons can also serve for protecting measuring devices mounted in the enclosure. The aprons can be fabricated from a heat-resistant metallic or ceramic material. The aprons or the pusher ram head can also be provided with a heat-resistant or heat-reflecting coating or with heat-resistant or heat-reflecting tiles. Also shown is a method for pushing of coke oven chambers by applying the inventive device.

         26 . The device as defined in  claim 24 , wherein the pusher ram head has any arbitrary shape so that the device for pushing has the extended outer shape of the cross-section of the pusher ram head. 
     
     
         27 . The device as defined in  claim 24 , wherein the cross-section of the enclosure varies in the rearwardly directed course so that the enclosure has any arbitrary shape. 
     
     
         28 . The device as defined in  claim 24 , wherein the aprons are shorter in length than the pusher ram. 
     
     
         29 . The device as defined in  claim 24 , wherein the aprons on the sides of the pusher ram head differ in length. 
     
     
         30 . The device as defined in  claim 24 , wherein the pusher ram has a round cross-section of any arbitrary shape and is cross-section-wise positioned in the center of the pushing device. 
     
     
         31 . The device as defined in  claim 24 , wherein the pusher ram has any arbitrary cross-section of any arbitrary shape and is cross-section-wise positioned at any arbitrary position of the pushing device. 
     
     
         32 . The device as defined in  claim 24 , wherein the device for pushing the contents of a coke oven chamber has exactly the cross-section of the opening of the coke oven chamber to be pushed or charged, respectively. 
     
     
         33 . The device as defined in  claim 24 , wherein the aprons are mounted on all sides of the pusher ram head. 
     
     
         34 . The device as defined in  claim 24 , wherein the aprons are mounted on less than all sides of the pusher ram head. 
     
     
         35 . The device as defined in  claim 24 , wherein the pusher ram for pushing-out the coke cake is a T-beam. 
     
     
         36 . The device as defined in  claim 24 , wherein the pusher ram for pushing-out the coke cake is a pusher ram comprising several T-beams welded together. 
     
     
         37 . The device as defined in  claim 24 , wherein the enclosure is wholly or partly made of a heat-resistant metallic material. 
     
     
         38 . The device as defined in  claim 24 , wherein the enclosure is wholly or partly made of a heat-resistant ceramic material. 
     
     
         39 . The device as defined in  claim 24 , wherein the pusher ram at the pusher ram head or on the enclosure or at the pusher ram head and on the enclosure is provided with a coating made of a heat-protecting material. 
     
     
         40 . The device as defined in  claim 39 , wherein the coating made of a heat-protecting material is applied in form of foils or tiles. 
     
     
         41 . The device as defined in  claim 39 , wherein the coating is applied as a high-heat reflecting layer in form of a “high-emission” coating.
