We consider the problems of complex structure teplotehnologicheskih complexes manufactures pulp and paper industry. Proposed and carried out structural analysis teplotehnologicheskih paper production complex in pulp and paper mills. Use graph theory and matrix analysis. Apply the authors developed a universal application in C # for the analysis of complex structured system of industrial circuits, power complexes. We obtained the results of the work program for the production of paper teplotehnologicheskoj scheme. Revealed all the circuits with the scheme. Identified torn flows for sequential calculation scheme without iterations. structural analysis program can be recommended for use and other industrial multi-loop circuit industry.

Keywords: structural analysis, feedback, teplotehnologicheskih scheme, industry, software, iteration

The article describes the conditions of use of heat pumps in the Russian industry. It proposed to introduce for the food industry, in particular for milk production, teplonanosnaya installation. Heat pump system allows to cover the heat load on the heating, ventilation and hot water supply of a specific milk production due to utilization of energy in the form of relief condensate produced in industrial drying processes. It is shown that the proposed plant will allow useful secondary steam and condensate will reduce fuel costs, simplify circuit heat consumption, reduce the cost of production of thermal energy, reduce operating costs for maintenance of heating systems, heat loss and reduce emissions into the environment.
