Abstract

In this paper, an application for the calculation of energy prices and product energy costs in the pulp and paper industry by using the Xi Plus expert system is presented. The use of expert systems in the energy field and also the Xi Plus expert system and its general features are also discussed. The application has been made after collecting data from several sources. It runs in an IBM AT compatible microcomputer therefore being easily used in mills. The name of the application is PRODUCT ENERGY COST. It has a three level structure: the mill level, the department level and the main equipment level. Currently, the mill level and, in the energy production area, the department level (power plant) and the equipment level (boilers, turbines) are used. The application consists of four knowledge base groups. Altogether there are 52 separate knowledge bases having 534 rules or demons. The knowledge base groups are: BASIC DATA, ENERGY USE, ENERGY PRODUCTION and ENERGY COSTS. The application can be used for various heat and electrical energy price calculations or for energy cost calculations for different pulp and paper products. In this study, the energy prices for kraft pulp, TMP, newsprint and fine paper in different operating conditions and the associated energy costs of the products are calculated. Also, in some cases a sensitivity analysis is done. The expert system is quite suitable for this type of calculation and the method could be further developed for specific industrial needs, e.g. to enhance the energy management systems.
