Operating site with an electricity/heat generator which functions on a combustion basis

Abstract

An operating site ( 1 ) with an electricity/heat generator ( 2, 3 ) which functions on a combustion basis, the waste heat of which generator is to some extent used to heat the operating site ( 1 ), wherein the operating site further has at least one thermal treatment chamber ( 20 - 25 ) for the subjecting of products arranged therein to heat and is set up for the exhaust gas of the electricity/heat generator ( 2, 3 ) to flow directly through the at least one thermal treatment chamber ( 20 - 25 ). In this case, at least one additional heater ( 26 - 32 ) which functions on a combustion basis for heating of the treatment chamber ( 20 - 25 ) is provided and the exhaust gas which flows through the thermal treatment chamber ( 20 - 25 ) and the exhaust gas of the at least one additional heater ( 26 - 32 ) can be fed to a common post treatment.

1 . Operating site ( 1 ) with an electricity/heat generator ( 2 ,  3 ) which functions on a combustion basis, the waste heat of which generator is to some extent used to heat the operating site ( 1 ), wherein the operating site further has at least one thermal treatment chamber ( 20 - 25 ) for the subjecting of products arranged therein to heat, characterized in that it is set up for the exhaust gas of the electricity/heat generator ( 2 ,  3 ) to flow directly through the at least one thermal treatment chamber ( 20 - 25 ), wherein at least one additional heater ( 26 - 32 ) which functions on a combustion basis for supplementary heating of the treatment chamber ( 20 - 25 ) is provided and wherein the exhaust gas which flows through the thermal treatment chamber ( 20 - 25 ) and the exhaust gas of the at least one additional heater ( 26 - 32 ) can be fed to a common post treatment. 
   
   
       2 . Operating site according to  claim 1 , characterized in that the operating site ( 1 ) is a production plant for glass fibre products, wherein the at least one treatment chamber serves for drying the glass fibre products produced, in particular in the form of glass fibre mats. 
   
   
       3 . Operating site according to  claim 1  or  2 , characterized in that at least one controllable valve ( 44 - 49 ) for regulating the throughput quantity of the exhaust gas of the electricity/heat generator ( 2 ,  3 ) which is to be channelled through the treatment chamber ( 20 - 25 ) is provided for achieving the desired process temperature in the at least one treatment chamber ( 20 - 25 ), wherein temperature fluctuations of the exhaust gas which is flowing through the treatment chamber ( 20 - 25 ) that may arise can be compensated by means of the at least one additional heater ( 26 - 32 ) to achieve a constant temperature in the treatment chamber ( 20 - 25 ). 
   
   
       4 . Operating site according to any one of the preceding claims, characterized in that a plurality of thermal treatment chambers ( 20 - 25 ) are provided, each with at least one additional heater ( 26 - 32 ), wherein the exhaust gas of the electricity/heat generator ( 2 ,  3 ) is, by means of suitable distribution and combining means ( 11 - 19 ;  34 - 41 ), distributed to the various treatment chambers and subsequently combined again for common post treatment with the exhaust gases of the additional heaters ( 26 - 32 ). 
   
   
       5 . Operating site according to  claim 3  and  claim 4 , characterized in that for each treatment chamber ( 20 - 25 ), a separate valve ( 44 - 49 ) for regulating the throughput quantity of the exhaust gas to be channelled through the respective treatment chamber ( 20 - 25 ) is provided, so that the temperatures in the various treatment chambers ( 20 - 25 ) can be set separately and independently of one another. 
   
   
       6 . Operating site according to any one of the preceding claims, characterized in that the post treatment is a mechanical or chemical cleaning of the exhaust gas.
