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 1):
A water-based heat transfer fluid cooled system that is intrinsically safe from BLEVE when used in a pyro-metallurgical furnace, comprising:\n at least one water-cooled appliance comprising a vertical lance, a subsonic top submerged lance (TSL), a sonic lance, a torch, a tuyere, and a burner block, as are variously included in both ferrous and nonferrous pyro-metallurgical furnaces; a coolant circulation network disposed in, jacketed around, or embedded within the water-cooled appliance of the furnace and providing for intrinsically safe liquid cooling of the appliance; a coolant comprising a blended mixture of a single phase organic compound of glycol alcohol, water, and a corrosion inhibitor, wherein the water is limited to a range of about 10% to 50% of the total by weight, and wherein all of the water is fully absorbed in the glycol alcohol; and a pump with a particular critically sized minimum capacity dependent on the viscosity and specific heat of the coolant and that circulates the coolant through the coolant circulation network at a predetermined minimum volume and velocity to preclude film boiling; wherein, the coolant continually physically absorbs the water and desiccates the interior passages of the coolant circulation network such that a leak of the coolant into the pyro-metallurgical furnace cannot cause a BLEVE with free water.
