Abstract

Patente de Invenção: <B>"SISTEMA DE REGULAGEM DE GáS PARA ALTO-FORNO"<D>. Um sistema para introduzir uma mistura homogênea de gás natural e de oxigênio nos algaravizes de um alto-forno. Incluídos no sistema estão condutos de gás com controladores de fluxo conectados a um misturador que produz uma mistura homogênea. Provisões são feitas para se desviar do misturador e para introduzir um gás inerte no misturador para impedir a formação de misturas de gás explosivas.Invention Patent: <B> "GAS REGULATION SYSTEM FOR HIGH OVEN" <D>. A system for introducing a homogeneous mixture of natural gas and oxygen into the algaravizes of a blast furnace. Included in the system are gas ducts with flow controllers connected to a mixer that produces a homogeneous mixture. Provisions are made to bypass the mixer and to introduce an inert gas into the mixer to prevent the formation of explosive gas mixtures.
