Abstract:
A cooling system for use in support of a pyro-metallurgical furnace includes a liquid heat transfer fluid blend of 10%-50% water with monoethylene glycol (MEG), diethylene glycol (DEG), or triethylene glycol (TEG), and corrosion inhibitors. When using such glycols, a minimum of 10% water prevents the heat transfer fluid from becoming too viscous for economical pumping, and a maximum of 50% water prevents BLEVE incidents inside the furnace. Such intrinsically safe cooling system circulates the liquid heat transfer fluid blend with an optimally sized pump, filtration, pressurization, and at flow velocities sufficient to avoid film boiling.

Claim (Index 5):
A gas injection system for a pyro-metallurgical furnace, comprising:\n a heat transfer fluid mixture of water, corrosion inhibitors, and monoethylene glycol (MEG), and having in combination simultaneous predetermined limits on viscosity and specific heat; wherein, the heat transfer fluid mixture is intrinsically incapable of a boiling liquid expanding vapor explosion (BLEVE); a cooling system that extracts and disposes of heat from the heat transfer fluid mixture and that provides liquid pumping for minimum circulation velocities that preclude film boiling of the heat transfer fluid mixture; and a gas injection lance with a liquid cooled jacket that extends the full length to a lance tip, and that receives the heat transfer fluid mixture from the cooling system, and that returns heated heat transfer fluid mixture, and that thwarts thermal curving of the gas injection lance by precluding uneven heating of it during operation; wherein, the liquid cooled jacket maintains a minimum velocity of the heat transfer fluid mixture within at any particular point to prevent film boiling; and wherein, the gas injection lance includes a conduit for the injection of a gas flow into a ferrous or nonferrous pyro-metallurgical furnace.
