Industrial Furnace Mastery

The document discusses a training course on furnace design and operation over three days. It will cover topics like combustion processes, furnace fuels, burner selection, aerodynamics, safety, and optimization. The goal is to enable attendees to develop and operate industrial furnaces effectively. Furnaces are classified into different types based on their design and examples are given. Design objectives are outlined like producing a quality product using minimum energy and costs while achieving a long service life. Common industrial furnace types are then briefly described like pottery kilns, cement kilns, glass furnaces, and those used in steel, copper, and oil refining.

Furnace design and

operation

Presented by
Prof. Barrie Jenkins
Kuala Lumpur, Malaysia, 18 - 20th July 2011
Introduction

 The course is designed to enable


attendees to develop and operate
industrial process furnaces to maximise
their potential
 Over the next three days comprehensive
training in all aspects of furnace design
and operation will be covered
Introduction

 Topics that will be covered include


 the combustion process and its control
 furnace fuels
 combustion and process efficiency
 burner design and selection
 aerodynamics
 safety and control
 optimisation
Introduction

 Each of the lectures is designed to


develop the subject from its engineering
basics to their specific application to
furnaces, concentrating only on those
aspects that are relevant and important,
and using practical examples to
demonstrate their use

What is a furnace

 Heat is liberated by burning fuel with air (or oxygen), or


from electrical energy, and some of this heat is
transferred to the product. The remaining heat leaves in
the flue gas and through openings such as charging
doors, or is lost from the external surface
Design objectives
 1. Obtain a satisfactory product
 2. Use minimum fuel and energy to achieve that product
 3. Construct the furnace for the lowest capital cost
 4. Operate with the lowest possible manning levels
 5. Achieve a satisfactorily long life with low maintenance costs
 Objective 1 overrides all others because, if the product is
unsatisfactory, then it cannot be sold or must be sold for an inferior
price
 While safety has not been included in the above objectives, it can
be taken as “a given” in today’s environment
 The art of furnace design involves achieving the best combination
of these five objectives over the entire life of the furnace, in other
words to produce a high quality product at the lowest achievable
cost
