Direct vs. indirect heating technology

 · Quite simply, direct heating technology involves a bulk solid material coming into direct contact with a heating gas to change the final temperature of the material. On the other hand, indirect heating technology does not allow the product to come in contact with air or gas or any other heating agent to change the final temperature.

Working Principles of Ceramic Heating Elements

 · Silicon carbide ceramic heating elements also boast improved electrical efficiency, converting of all electricity supplied into heat with a shallow drop-off in terms of watt loading. The drawback of exposed ceramic heating elements comprised of silicon carbide is that the material is not fully densified, which makes it susceptible to cross-reactivity with atmospheric gases at elevated ...

What is a Heat Exchanger and How Does it Work?

 · Secondary Heat Exchanger If you have a furnace that is considered high-efficiency (90%+ efficient), it contains both a primary and secondary heat exchanger. As the combustion exhaust leaves the primary heat exchanger, it travels into a secondary heat exchanger where more heat is released from the flue gas and water vapor begins to form.

DESIGN OF SHELL AND TUBE HEAT EXCHANGER

Do not use finned tubes when shell-side fouling is high. Stream with a lower heat transfer coefficient goes on the shell side. Toxic fluid should be placed on the tube side. 5.2 Shell and Tube Velocity High velocities will yield high heat transfer coefficients but also a

What''s the difference between parallel flow, counter flow and crossflow heat …

 · It''s important to note that because the heat exchange rate isn''t as high as other flow patterns, parallel flow heat exchangers need greater heat transfer surface area. As such, it''s critical that facility executives ensure they have the available floor space for their parallel flow shell and tube heat exchangers, as they may be larger than another exchanger with a different flow rate.

1. Basic heat transfer

Glossary. The most basic rule of heat transfer is that heat always flows from a warmer medium to a colder medium. Heat exchangers are devices to facilitate this heat transfer with the highest possible efficiency. A good heat exchanger is able to transfer energy (heat) from the hot side to the cold side with small thermal losses and high efficiency.

Design Considerations When Using Heat Pipes | Electronics Cooling

 · First, minimum bend radius is three times the diameter of the heat pipe. Second, every 45 degree bend will reduce Q max by about 2.5%. From Table 1, an 8 mm heat pipe, when flattened to 2.5mm, has a Q max of 52 W. Bending it 90 degrees would result in a further 5% reduction. The new Q max would be 52 – 2.55 = 49.45 W.
