STRUTTURA DI RECIPIENTE DI RISCALDAMENTO IN PARTICOLARE PER LA MODIFICAZIONE DELLA CIRCOLAZIONE DEL GAS DI SCARICO ENTRO UN FORNO DI LIQUEFAZIONE AD ALTA TEMPERATURA.

摘要

The circulation of exhaust gas within a heating vessel is controlled to reduce the adverse effects of the abrasive and corrosive exhaust gas on exposed interior surfaces of the vessel. The firing rates of the burners in the vessel may be varied to alter the flow patterns within the vessel. Additional jet burners with high exhaust gas velocity may be used to direct their exhaust flow in a direction opposing the exhaust flow of other selected burners. Burners may also be angled so as to reduce the flow component of the exhaust gas that may pass over the exposed interior surfaces of the vessel.
