This Application Note illustrates the use and advantages of dielectric heating, which as the name implies, is used for materials that are non-conducting. The essential advantage of dielectric heating is that the heat is generated within the material to be heated. In comparison with more conventional heating techniques (hot air, infrared, et cetera) in which the material is heated via the outer surface, dielectric heating is much more rapid. This is because electrical insulating materials, i.e. the domain of dielectric heating, are usually also poor conductors of heat.
Other interesting characteristics of radio frequency and microwave heating are the high power density and the potential for selectively heating materials. However, dielectric heating is a very expensive technique that cannot usually compete in cost terms with techniques such as resistance or infrared heating.
Resistance heating deals with the heating of conducting materials, metallic or non-metallic, in which an electrical current (DC or AC) flows.
In Direct Resistance Heating (DRH) the electrical current flows directly in the con-ducting workpiece to be heated; in Indirect Resistance Heating (IRH) the current flows in special resistance elements, from which the heat is transferred to the work-piece by radiation and convection. Resistace elements and workpiece are situated in a furnace.
Both heating systems must be conveniently designed in order to maximize efficiency and obtaining the desired heating pattern in the workpiece.
In the course the following topics will be dealt with:
• DRH with DC supply
• DRH with AC supply
• Characteristics of DRH bar heating installations
• IRH resistance furnaces
• Materials and design of IRH furnaces
• DRH and IRH heating systems efficiency

Induction Heating – Operation, Applications and Case StudiesLeonardo ENERGY
The industrial process heating applications that use electrotechnologies have been found to improve product quality, productivity, energy efficiency, reduce energy intensity and have many other non-energy benefits. Induction technology is another electrotechnology based heating method for heating electrical conductive materials. It involves sending an alternating current (AC) through a copper coil which surrounds the material to be heated or melted. When a metal is placed inside the coil and enters the magnetic field, circulating eddy currents are induced within the metal. The resistance of the metal to the flow of the eddy currents causes the metal to heat up. In this webcast, the operation principles of induction heating technology used for both heating and melting, its applications and EPRI case studies will be presented. The information of vendors as well as other links to reference materials will be presented at the end.

Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.

2. WHAT IS ELECTRIC HEATING ?
WHAT IS THE PRINCIPLE BEHIND IT ?
Electric heating is any process in which
ELECTRICAL ENERGY is converted to
“HEAT ENERGY”.
Electric heating works on the principle
of ”JOULE HEATING” (an electric
current through a resistor converts
electrical energy into heat energy.)
3. INTRODUCTION
Electrical heating is based on the principle of that
when electric current passes through a medium
heat is produced. Let us take the case of solid
material which as resistance ‘R’ ohms and current
flowing through it is I amps for ‘t’ seconds than heat
produced in the material will be H=I²Rt Joules.
4. DOMESTIC APPLICATION OF
ELECTRICAL HEATING
Room heater for heating the building
Immersion heater for water heating
Hot plates for cooking
Geysers
Electric kettles
Electric Iron
Electric oven for baking products
Electric toasters etc…
5. INDUSTRIAL APPLICATION
Melting of metals
Electric welding
Mouldling of glass for making glass
appliances
Baking of insulator
Mould ling of plastic components
Heat treatment of pointed surpasses
Making of plywood.
6. ADVANTAGES OF ELECTRICAL HEATING
OVER OTHER METHOD OF HEATING
• Clean and atmosphere / Free from dirt.
• No pollution / No flue gas is produced
• Response quickly
• Accurate Controlled temperature can made easily
• Comparatively safe
• Localized application
• Overall efficiency is much higher
• Uniform heating
• Highest efficiency of utilization
• Cheap furnaces
• Mobility of job
7. TRANSFER OF HEAT
Conduction:- This phenomenon takes place
in solid, liquid and gas.
Heat transfer is proportional to
the difference of temperatures between two
faces.
No actual motion of molecules.
8. Convection
This phenomenon takes place in liquid
and gas. Heat is transferred due to
actual motion of molecules
Radiation
This phenomenon is confined to
surfaces. Radiant energy emitted or
absorbed is dependent on the nature
of the surface.
9. CLASSIFICATION OF ELECTRICAL
HEATING

1. Resistance heating 1. Induction heating
a. Direct Resistance heating a. Direct Core type
b. Indirect Resistance heating b. Core less type
2. Arc heating 2. Dielectric heating

b. Indirect Arc heating
10. Classification of Heating Method:-
Low Temperature Heating ± up to
400°C
Medium Temperature Heating ± from
400°C to 1150 °C
High Temperature Heating ± above
1150 °C
11.
12. 1) high resistivity
2) able to withstand high temperatures
without deterioration
3) low temperature coefficient of
resistance
4) positive temperature coefficient
of resistance
5)free from oxidation at high
temperatures
Characteristics of Heating Elements
13. RESISTANCE HEATING
(Example – Electric Water
Heater)
This method is based upon the I²R loss.
Whenever current is passed through a
resistor material heat is produced because
of I²R losses.
The generation of heat is done by electric resistor
carrying current.
14. RESISTANCE HEATING
DIRECT HEATING
• Electric current is
passed through the
body (charge) to be
heated.
• High efficiency
• Mode of heat transfer
is Conduction
• Example-
1) Electrode boiler for
heating water
2)Resistance Welding
INDIRECT HEATING
• Electric current is passed through
highly resistive material(heating
element) placed inside an oven.
• Heat produced due to I²R loss in
the element is transmitted to the
body
• Mode of heat transfer is Conduction
&/or Convection &/or Radiation
• Example-
1) Room Heaters
2) Domestic & commercial cooking
3) Heat treatment of metals
19. Dielectric Heating
Dielectric heating, also known
as electronic heating, RF heating, high-
frequency heating and diathermy.
Dielectric heating is a special way of
transforming electric current into heat.
By the method of dielectric heating,
generally, foils, plates and profiles with a
thickness of 0,1-2,0 mm is are welded.
20. Dielectric Heating (contd…)
• We understand dielectric heating as the
generation of thermal energy (heat) in a non-
conducting material by the application of an
electromagnetic force or field t it. This is the
way a microwave oven heats things placed in
it.
