Možné způsoby optimálního výběru "Utility-Systémů"

Possible Aproach for Optimum Selection of Utility Systems

Increasing demand for heat and power is without doubt one of the major problems both in the process industry and elsewhere. This problem can be solved by improving existing heat and power systems and/or by retrofit of existing processes. This paper strives to provide an overview of convenient methods for rapid and optimum (and/or near optimum) selection of utilities. The choice and trade-off is based on a relation between a process and utility system. Simple mathematical models created or adapted especially for this purpose are described. Further, criteria for evaluation of the most suitable system from economic, technical and environmental points of view are specified. Combined heat and power (CHP) systems are discussed including their utilizing in a process. Various trends of further development in the field are described and discussed.

Tento příspěvek sa snaží poskytnout přehled konvenčních metod používaných pro rychlý a optimální (nebo skoro optimální) výběr jednotlivých "utilit". Výběr a kompromis jsou založeny na vztahu mezi procesem a "utility systémem". Jednoduchý matematický model vytvořený a přizpůsobený speciálně pro tento účel je popsaný v tomto příspěvku. Taktéž kritéria pro vyhodnocení nejvhodnejšího systému z ekonomického, technického a environmentálního hlediska jsou specifikována. Kombinované systémy výroby elektrické energie a tepla zahrnující jejich využití v procesu jsou v tomto příspěvku diskutovány. Dále jsou popsány a diskutovány různé trendy dalšího vývoje v této oblasti.

Trade-off, utility systems.
