INDIRECT FIRED HEATER 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 SPECIFICATIONS Technical features Powers between 0.1 and 15 MW Codes of design: AD-2000, DIN 4754, ASME VIII Div. 1 Marked CE Design pressure: 8 bar_g Max. working pressure: 7 bar_g Design temperature: 400º C Max. working temperature: 350º C Number of coils: 2 Number of smoke passes: 3 Thermal efficiency: 87 – 91% (*) Material’s quality of coils: ASTM A106 Gr.
