Original abstract
Discussion about utilization of waste for energy production (waste-to-energy, WTE) has moved on to next development phase. Waste fired power plants are discussed and investigated. These facilities focus on electricity production whereas heat supply is diminished and operations are not limited by insufficient heat demand. Present results of simulation prove that increase of net electrical efficiency above 20 % for units processing 100 kt/y (the most common ones) is problematic and tightly bound with increased investments. Very low useful heat production in Rankine-cycle based cogeneration system with standard steam parameters leads to ineffective utilization of energy. This is documented in present paper with help of newly-developed methodology based on primary energy savings evaluation. This approach is confronted with common method for energy recovery efficiency evaluation required by EU legislation (Energy Efficiency – R1 Criteria). New term highly-efficient waste-to-energy is proposed and condition under which is the incinerator classified as highly-efficient are specified and analyzed. Once sole electricity production is compelled by limited local heat demand, application of non-conventional arrangements is highly beneficial to secure effective energy utilization. In the paper a system where municipal solid waste incinerator is integrated with combined gas-steam cycle is evaluated in the same manner.
Czech abstract
Diskuze o využití odpadů k výrobě energie (waste-to-energy, WTE) se posunula do další vývojeové fáze a mluví se o tzv. elektránách sodpademjako palivem (Waste fired power plants). Tato zařízení se zaměřují na výrobu elektřiny přičemž dodávka tepla je omezována nebo zcela vypuštěna. Prezentované výsledky simulačních výpočtů potvrdili, že zvýšení čisté účinnosti výroby elektřiny nad 20% pro jednotky se zpracovatelskou kapacitou 100 kt/r je problematické a je úzce spojeno s vyššími investičními náklady. Nízká produkce užitečného tepla v kogeneračním systému založeném na Rankinově cyklu s nízkými parametry páry vede k neefektivnímu využití energie. To je v příspěvku dokumentováno na základě metodiky vytvořené autory příspěvku. Metodika založená na vyčíslení úspor primární energie je porovnána s běžným způsobem hodnocení systému WTE, který je ukotven v evropské legislativě (Energy Efficiency – R1 Criteria). V příspěvku je zaveden nový pojem vysoce-účinný proces waste-to-energy.
