Abstract

PORTA DE CALDEIRA DE VAPOR COMPREENDENDO UM SISTEMA DE REFRIGERAçãO. Trata-se de um sistema refrigerante para portas de ar (4) e outras portas em paredes de fornalha (1) inclui um sistema de bombeamento de meio refrigerante e portas dotadas de um cano de meio refrigerante (3) ou canais dentro do material de porta metálica (2). O fluxo de líquido gerado através do sistema de meio refrigerante resfria as portas. As portas são construídas por um material de fundição (2) e as portas são dotadas de um fluxo de líquido refrigerante, que passa em uma cano (3) ou canos ou canais dentro do material de fundição das portas.
