Power plants and heating systems for woodprocessing works

In the article power plants in combination with hot water heating systems (total energy systems) which supply production equipments with the main energies - electricity and heat - are discussed. Their conception is illustrated and described on the schematic flow-diagrams in two altennatives: one with the single-stage heating system and the other with the multi-stage one. General equations to determine size and performances of the main parts are derived. The energy losses of the power plant with the single-stage heating system are calculated which can be avoided when applied the multi-stage heating system. Instructions for the application and the suitability in the industrial practice depending on the number of heat consumers and the variety of their working temperatures are given. A coefficient of the utilization of the steam energy of the total energy system is introduced and specified.
