An indirect Fired Heaters can be understood as a boiler. The energy produced by the combustion of liquid or gas fuels in the boiler, is transferred to a heat-transmitting intermediate fluid – basically water in liquid or gas form or thermal fluids, which is responsible for transporting the energy to other equipment – reactors, exchangers, etc. – to feed the productive process.
Therefore, under this term we can group steam, hot water and thermal fluid boilers.
Obviously their applications are infinite, as heating is indirect and the final product of the process is heated by the fluid transmitting heat in exchangers, reactors, press plates, etc.
So, we can consider:
Petrochemical industry
Food industry
Textile industry
Flexography and rotogravure
Industrial laundry
Heating of all kinds of presses
Automobile industry
Industrial adhesives and glues
Solar energy
Etc, etc
