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 4):
An oxidizing gas injection system for a pyro-metallurgical furnace, comprising:\n an oxidizing gas injector for a pyro-metallurgical furnace; a cooling jacking disposed outside, around and along the full length of the oxidizing gas injector; a heat transfer fluid mixture comprising water, corrosion inhibitors, and glycol, and that combined has a predetermined specific heat greater than 2.3 kJ/kg\u00b7K, and a predetermined viscosity of less than 20 mPa\u00b7s, and wherein, the heat transfer fluid mixture is intrinsically incapable of a boiling liquid expanding vapor explosion (BLEVE); a liquid pumping system that circulates the heat transfer fluid mixture through the cooling jacking and that maintains a minimum fluid velocity at predetermined points within the cooling jacket to prevent film boiling of the heat transfer fluid mixture; a coolant pressurization system connected to contain the heat transfer fluid mixture and raise its boiling point; a filter connected to remove contaminants from the heat transfer fluid mixture; and a heat exchanger connected to remove and dispose of heat from the heat transfer fluid mixture.
