Interest in heat engineering has increased again in a time in which‎,‎ on the one hand‎,‎ industrial‎-furnace technology is booming and‎,‎ on the other hand‎,‎ costs for gaseous fuels and electrical energy are rising rapidly‎.‎ In addition‎,‎ the rational utilization of energy in heat‎-processing technology is set to attain an ever more central significance due‎,‎ not least of all‎,‎ to current controversies on the subject of CO2 emissions‎.‎ The work examines from a practical viewpoint the current state of the technological art and all relevant fundamental principles of heat transfer‎,‎ fluid mechanics and combustion systems‎.‎ The reader is provided with a detailed overview of all relevant principles‎,‎ calculations‎,‎ terms and processes in industrial heat engineering‎,‎ and thus with important aids for his or her daily work‎.‎ This compact‎-format book‎,‎ with its plethora of information‎,‎ is an indispensable reference for all those involved in any way at all with thermal processing technology and industrial‎-furnace engineering and operation‎.‎
