[5, 6] Also the rules of European Union impose the strict control of the processes within a FNC's technological flux. This article presents the analysis and the measurements of pollutant emissions that were carried out in different points on the technological flux of the combined fodder. We need to mention that the results of these measurements were, throughout the batch of assortement, within the limits of the actual law. INTRODUCTION The processes that are carried out along the technological flux of a FNC are: reception-storing, transportation to different installation, recirculation, processing, packing, storing-delivery. Within the manufacturing process of raw materials is performed the crumbling, then they are mixed, and under a jet of steam which is generated by a steam generator it will obtain particles of different forms and dimensions. . The steam from the generator has a role of homogenization of the particles and sterilizing them. At the end of the steam generator it has been taken samples and it has been made different measurements in order to analyze the functional parameters of the installation. So, in this working point it has been measured the burning gas emissions resulted from obtaining the jet of steam necessary to the homogenization of the mass of the prime matter in order to obtain compound feed grains. These analysis and measurements of the emissions of the burning gas at the end of the steam generator were made with the help of the gas analyzer TESTO 350 M/XL, during an interval of 100 minutes, which represents the minimum time required to create a batch of compound feed grains. MATERIAL AND METHOD The analysis principle is based on the changing the intensity of the galvanic current generated by a galvanic battery of who’s electrolyte modifies its properties, after its reaction with gas component which needs to be detected and which concentration needs to be measured [1, 2, 8]. The measurement cells are represented of some galvanic elements, which generate a current proportionally with the number of ions which is dissociate in the solution of electrolytes, as a result of the interaction with the studied gas. Analyzers built by this principle are much cheaper compared to infrared-based analyzers, but may only be used for short or normal periods of time, usually by portable devices. With the aid of these instruments, one could determine the concentration of any of the following gases : O 2 , CO, H 2 S, NO, NO 2 , SO 2 , etc. [1, 2, 3, 4] brought to you by CORE View metadata, citation and similar papers at core.ac.uk provided by Annals of the University of Craiova - Agriculture, Montanology, Cadastre Series
