Recycling Hydrogen with a Novel Electrochemical Process

January 8, 2013

In numerous controlled-atmosphere, metallurgical-based heat-treating processes, hydrogen becomes an expensive wasted asset because it is typically vented or flared shortly after being introduced into the furnace. This practice is predominately due to the lack of commercially available, cost-effective, reliable recycling technology.

Helium Leak Detection

Geoff Humberstone

November 29, 2012

Finding leaks in a furnace or chamber that has been used for several years takes some careful “sniffing” around using a helium leak detector. However, it’s easy to get sidetracked and frustrated if you are not careful.

Getting the Most Out of Your Combustion System

Brian Kelly

September 30, 2012

The production of high-quality heat-processed products (steel, alloys, aluminum, ceramics, etc.) at the lowest cost depends largely on the quality and integrity of the combustion system.

If your facility has a gas line running onto your property, there are new rules that will impact you, no matter what kind of business you are in.

Computer Modeling Helps Identify Induction Heating Misassumptions and Unknowns

Dr. Valery Rudnev

October 6, 2011

Whenever someone is discussing induction heating, reference is often made to the skin-effect phenomenon, which is a fundamental property of induction heating. It can be clearly observed during billet heating. Skin effect represents a nonuniform distribution of an alternating current within the workpiece cross section.

The Basics of Pulse Firing

October 3, 2011

The primary purpose of a furnace is to provide heat to the product or load, so basic knowledge of desired furnace heat-transfer characteristics helps in understanding why and how pulse firing can be beneficial.

The Basics of Pulse Firing (Part 2)

Dan Curry

October 3, 2011

The basics of pulse firing were discussed in October’s article. This online-exclusive part summarizes some of the advantages and disadvantages of pulse as compared to traditional amplitude-modulating systems.
