Abstract
instalação e método para extrair e resfriar cinzas pesadas a presente invenção refere-se a uma instalação (1) e a um método para extrair e resfriar cinzas pesadas, com recuperação de energia térmica, do tipo apto para ser usado em associação com uma câmara de combustão, em particular para grandes fluxos de cinzas pesadas derivados, por exemplo, de combustível fóssil sólido em uma usina de produção de energia. a instalação (1) de acordo com a invenção compreende: meios (9,1 o 6) para extrair e transportar cinzas pesadas provenientes da câmara de combustão (100); um sistema de resfriamento (10, 11, 19, 17, 12) para resfriar das cinzas pesadas, disposto nos meios de extração e transporte (9, 6) e aptos a determinar uma alimentação de ar de resfriamento nos últimos, o arranjo global sendo tal que pelo menos parte do ar de resfriamento pode ser introduzida na câmara de combustão (1 00) a partir do seu fundo; meios de isolamento de pressão (8), aptos a determinar uma separação das atmosferas entre um primeiro (9) e um segundo (6) ambiente dos meios de extração e transporte (9, 6), o primeiro ambiente (9) sendo conectado à atmosfera da câmara de combustão (100) e o segundo ambiente (6) sendo capaz de ser conectado com um duto de admissão de ar (50, 57) para um trocador de ar/fumos (102) ou para uma entrada de ar do último; meios (51) para alimentar parte do ar de resfriamento para o interior do duto de admissão de ar (50, 57) para o trocador de ar/fumos (102) ou para a entrada do último; e, meios de controle, aptos a determinar a ativação do isolamento de pressão de ambientes, dependendo da temperatura e/ou fluxo de cinzas.Installation and method for extracting and cooling heavy ashes The present invention relates to an installation (1) and a method for extracting and cooling heavy, energy-recoverable ashes of the type suitable for use in combination with a combustion, in particular for large flows of heavy ash derived from, for example, solid fossil fuel in a power plant. The plant (1) according to the invention comprises: means (9.1 or 6) for extracting and transporting heavy ashes from the combustion chamber (100); a cooling system (10, 11, 19, 17, 12) for cooling from heavy ashes, arranged in the extraction and transport means (9, 6) and able to determine a cooling air supply in the latter, the overall arrangement being such that at least part of the cooling air may be introduced into the combustion chamber (100) from its bottom; pressure isolating means (8), capable of determining a separation of atmospheres between a first (9) and a second (6) environment of the extraction and transport means (9, 6), the first environment (9) being connected to the combustion chamber atmosphere (100) and the second environment (6) being capable of being connected with an air inlet duct (50, 57) to an air / smoke exchanger (102) or to an air inlet of the latter ; means (51) for supplying part of the cooling air into the air intake duct (50, 57) to the air / smoke exchanger (102) or to the latter inlet; and control means, capable of determining the activation of ambient pressure isolation, depending on temperature and / or ash flow.
