Potenciál využití plynových mikroturbin v komerčních prádelnách

Potential of gas microturbines for integration in commercial laundries

journal article in Web of Science

Application potential of microturbines moved from back-up sources for electrical energy and island operation systems, and expended as a combined source for electrical energy and heat in commercial facilities and residential premises. In this paper, we wish to present an analysis of gas microturbine integration in a commercial laundry. We opted for a professional laundry care since it is a common representative of a well-known process which requires a lot of energy input. We focus on commercial laundries with a capacity over 1000 kg of processed laundry per shift. This type of laundries is very common. The gas microturbine was considered as a cogeneration unit as it has a process-adequate performance (30 kWe). Its flue gas helps heat main laundry input flows: hot water for the washing machines and hot flue gas for the dryers. Prices of commercial microturbines are still rather high and short payback period may be expected only if very specific conditions are met.

Plynové mikroturbíny už neslouží pouze jako záložní zdroje, ale stále častěji jako kogenerační systémy v komerčních provozech i v sektoru bydlení. Článek prezentuje integraci mikroturbíny (30 kWe) v komerční prádelně se zpracovatelskou kapacitou přes 1000 kg prádla za směnu. Tento typ prádelen je velice rozšířený v rámci EU. Odpadní teplo z mikroturbíny může být využito pro ohřev prací vody i pro přímé sušení prádla. Stuie ukazuje podmínky, za kterých je investice do tohoto kogeneračního systému opodstatněná.
