Hotel Estoril Eden, Estoril-Lisbon, Portugal, 19-20 March 2007



The challenges for the near future are the need for the development of new solutions for sustainable energy supply and increasing energy prices. The general tendency with increasing energy prices will continue because of an expected increase in energy consumption by 50% during the next 25 years.


Within this context the importance of rational use of energy is increasing from day to day. According to the actual energy prices the payback time for the implementation of the latest energy saving technologies has been cut by 50% during the last 3 years in many applications. One of the best options for energy recovery from flue gas is preheating of the combustion air. For example in process heating between 30 and 70% of the energy consumption could be reduced with novel technologies. In order to prevent a strong increase of NOx emission in conjunction with increasing air preheating latest combustion technologies have to be employed. Within this context the new flameless combustion technology offers a big potential in order to avoid high NOx emission.


Besides the NOx reduction potential flameless combustion has a lot of other advantages like uniform temperature distribution within the combustion zone, improvement of product quality, reduced noise emissions and enhancement of heat transfer. The advantages of this innovative combustion technology can be applied in different areas like process technology and power generation (boilers and gas turbines). The technology is applicable to all kind of fuels like natural gas, fuel oil and coal and is on the marked for air fuel and oxy-fuel combustion.


This Short Course on flameless combustion and energy saving technologies is particularly concerned with improving the energy and environmental performance of combustion equipment like fuel-fired high-temperature furnaces, boilers, gas turbines and other combustion equipment. Consequently the Course will provide a greater understanding of the principles associated with the efficient application and operation of novel combustion and energy saving technologies.

The Course provides an overview about the state of the art of the latest waste heat recovery technologies for preheating of the combustion air and will introduce the fundamentals of the flameless combustion technology. Additionally actual applications of the technology will be presented and the potential of the technology for the future will be highlighted. 

The Course will involve lectures and case studies. Delegates will be encouraged to take part in discussions on the topics covered in the sessions to ensure that they obtain maximum benefit from the Course and comprehensive handouts will be provided.




The Course is dedicated to people who are the decision makers in industry and politics, engineers and technicians from plant operating companies as well from engineering and consulting companies. The Course will be of value to staff who are responsible for the efficient management and operation of combustion equipment like industrial furnaces, gas turbines, boilers and other combustion equipment. It will also benefit personnel involved with technical marketing of combustion equipment and those working in associated fields such as fuel technology and energy management. Additional it will be also informative for people from research funding organization and politicians. Research staff working in relevant areas may also find the Course of value since it provides an overall grounding to understanding the behavior of flameless combustion technology.
