A heater assembly with enhanced cooling pursuant to various embodiments described herein makes use of fluidic flow in the insulation or in the space used for insulation. By creating a natural convection or forced convection flow, the heater cools down faster, it can operate at lower temperatures and/or higher temperature precision, and it can improve temperature controllability by generating higher heat loss rates.

A system used in monitoring one or more operating parameters of a coolant-fluid cooled industrial installation includes one or more an acoustic sensors positioned to receive and sense one or more acoustic signals in an installation coolant-fluid flow. The acoustic sensor assembly operates to emit and sense acoustic signals at frequency ranges above and/or below the background noise frequency ranges which are associated with the normal industrial installation operation. Output data signals representative of sensed acoustic signals are compared to target frequency profiles predetermined as representing an acoustic frequency associated with a predetermined installation operating parameter or event.

A quenching cell including an enclosure containing at least one element for stirring a quenching gas at a pressure greater than 0.4 MPa and a synchronous electric motor capable of rotating the stirring element.

A cooling plate for use in a blast furnace is described. The cooling plate contains a copper body having an inner face containing ribs parallel therebetween, having first extremities opposite therebetween and separated by grooves having second extremities opposite therebetween. At least one of these ribs contains at least one housing located between its first extremities and containing at least one insert made of a wear resistant material that increases locally the wear resistance of this rib.
