Abstract

"RECUPERADOR PARA TROCADOR DE CALOR". A invenção se refere a um recuperador para tocador de calor do tipo regenerativo de pré-aquecedores de fluidos. Trata-se de recuperadores de calor cilíndricos verticais (também conhecidos como 'Cowpers') utilizados para o pré-aquecimento do ar insuflado em altos fornos na indústria siderúrgica Os recuperadores de calor de acordo com a invenção consistem em conjuntos (A) constituídos por três camadas de tijolos refratários (1, 2 e 3), inferior, intermediária e superior, respectivamente as quais são sobrepostas sequencialmente com um deslocamento horizontal pré-estabelecido em relação às camadas imediatamente adjacentes, onde vários canais verticais (b) da camada superior (1) se sobrepõem vários canais verticais (g) da camada intermediária (2), e vários canais verticais (h) da camada intermediária (2) se sobrepõem a vários canais verticais (m) da camada inferior (3), proporcionando um fluxo tal que garanta a máxima circulação horizontal do fluido transportador de calor que passa através de todas as cavidades verticais da estrutura."HEAT EXCHANGER RECOVERY". The invention relates to a regenerative type heat exchanger of fluid preheaters. These are vertical cylindrical heat exchangers (also known as 'Cowpers') used for the preheating of blast furnace air in the steel industry. The heat exchangers according to the invention consist of assemblies (A) consisting of three lower, intermediate and upper refractory brick layers (1, 2 and 3), respectively, which are sequentially overlapped with a pre-established horizontal offset from the immediately adjacent layers, where several vertical channels (b) of the upper layer (1) ) overlap several vertical channels (g) of the intermediate layer (2), and several vertical channels (h) of the intermediate layer (2) overlap with several vertical channels (m) of the lower layer (3), providing a flow such that ensure maximum horizontal circulation of the heat carrier fluid passing through all vertical cavities of the frame.
