Abstract

"SISTEMA E MéTODO PARA AUMENTAR PRODUçãO DE UMA USINA DE ENERGIA DE CICLO COMBINADO". é revelado um sistema e método para aumentar produção específica de uma usina de energia de ciclo combinado e fornecer flexibilidade na classificação da usina de energia, ambos sem um aumento correlato na taxa de aquecimento da usina. A presente invenção demonstra que o processo de atualizar as eficiências térmicas de ciclos combinados muitas vezes pode ser feita através da utilização estratégica de combustível adicional e/ou insumo de calor. Em particular, turbinas a gás que exaurem dentro de HRSGs podem ser queimadas suplementarmente para obter emissões de turbina de vapor mais elevadas e maiores taxas de usinagem, mas sem uma penalidade na eficiência. Este sistema e método em grande parte define uma usina de energia de ciclo combinado de alta eficiência que é predominantemente um ciclo Rankine (bottoming) Versões exemplares da presente invenção incluem uma carga (1304) acionada por um TCE (topping cycle engine - motor de ciclo principal) (1302), acionado por um TCF (topping cycle fluid - fluido de ciclo principal) (1301) que exaure (1305) dentro de um HRD (heat recovery device - dispositivo de recuperação de calor) (1306). HRD (1306) é queimado com um combustível suplementar e/ou é fornecida uma fonte de calor adicional (1314) para produzir mais energia e/ou maior quantidade de BCF (bottoming cycle fluid - fluido de ciclo posterior) (1309) que é utilizado para energizar um BCE (bottoming cycle engine - motor de ciclo posterior) (1310) que aciona uma carga (1311) (potencialmente a mesma carga (1304) do motor de ciclo principal (1302)). A energia contida quer no TCF (1301) ou no BCF (1308) é utilizada para energizar o TCE (1302) e o BCE (1310) respectivamente, mas esses fluidos, e/ou suas respectivas exaustões, também podem ser utilizados para suportar uma ampla variedade de aplicações de cogeração.
