Drying with steam or drying with air - a case study for clay
Clay is a term used to describe a group of hydrous aluminium phyllosilicate. Phyllosilicates being a subgroup of silicate minerals that are typically less than 2 µm in diameter...

Fuel Cells Versus Heat Engines: A Perspective of Thermodynamic and Production Efficiencies
Fuel Cells are being developed as a powering method which may be able to provide clean and efficient energy conversion from chemicals to work. An analysis of their real efficiencies and productivity...

Equations for the Physical Properties of Moist Air
In a closed container partly filled with water there will be some water vapor in the space above the water. The concentration of water vapor depends only on the temperature. It is not dependent on the amount of water and is only...

Low Ionization Plasma Sources for Enhanced Aluminum Processing
Low ionization plasma melting of aluminum is shown to be effective due to the speed of melting and the highly efficient nature of the process. Additionally, the input power is low as compared to the alternatives, and it produces no noise and no emissions...

HGA output for Steam and Superheated steam
In engineering, steam refers to vaporized water. It is a pure, invisible gas (not a mist) which at standard atmospheric pressure has a temperature of around 100 degrees...

MHI Semiconductor Gas Abatement Physics and Principles
With the ever growing menace of perflourocompound emissions, MHI has pioneered an energy efficient way to abate these materials through a plasma process...

Does convection really enhance uniformity?
Very Often the key to high productivity lies in good uniformity in the furnace/oven.  As ovens become larger this is a key concern. Energy efficiency and uniformity are increased by...............

Processing Materials with Forced Air Convection
Material manufacturing involves several complex processing steps, many of which use heat to accelerate drying, firing, sintering and other operations. These processing steps are usually performed with gas or oil-fired burners in kilns or other types of equipment that often require a great deal of...

Economics of MHI PC Furnaces for Aluminum Industry
(requires macromedia flash player free from Macromedia web site)
A new PC-RAM-PLASMA™ method is the key to melting aluminum, cleanly and efficiently. The low cost plasma melting devices described in this report along with the power concentration technology is the key to

Heating Elements:  Which are the best type for me?

Manufactures often increase their productivity and quickly recoup their initial furnace investment by choosing the proper heating elements...
(a study by the National Academy of Engineers condensed for your use!!).  See also another article below on Productivity gains once you have identified the best heating elements.  What can you do more to increase productivity. (Productivity vs. Temperature)

MHI Foams for use in Fuel Cells
Fuel cells are electrochemical devices that convert the chemical energy of a reaction directly into electrical energy. A variety of fuel cells are in different stages of development. They can be classified by use of diverse categories, depending on the combination of type of fuel and oxidant, whether the fuel is processed outside...

Heating Elements for Higher Productivity

Experiments have shown that manufacturers can often increase their productivity and quickly recoup their initial furnace investment by choosing higher temperature heating elements...

Die Heating Comparison: Airtorch vs. Flame

The heating of the die is often the most critical start up procedure in forging, extrusion, and pressure die casting operations. Improper pre-heating results in a variety of problems, the most significant being low die life on...

Productivity vs. Temperature (in pdf format)

Productivity vs. Temperature (in flash paper format; requires macromedia flash player free from Macromedia web site )
Heating is an essential and expensive step in almost all material processing operations. The first decision which has to be made when choosing a heating device is...
.  A wrong decision on heating elements may prove extremely costly for productivity.   Determine which element may work best for you.
