Heat Supply Concepts for Industrial Conurbations with a View to Reducing Primary Energy Consumption.

The state of development of regional heat supply networks and the future need for substitution of considerable steam output capacities in industrial conurbations of the GDR require integrated long-term district heating concepts. For the communal heat supply, a significant part of the basic funds are tied down. They are utilized fully only for about 30% of the year. Their use for industrial heating requirements would result in an increase inthe utilization time factor and a more effective unloading of the production capacities with better energy utilization. Using an example, a concept is presented, in which steam heat is provided and the adjustment of the heat supply to the differentiated demand conditions takes place by means of a satellite turbine and storage with simultaneous utilization of steam power for electric power generation.
