Thermal specificities:
Quiri, specialist in heat exchangers, introduces you an electrical fuel heater.
We have delivered this type of exchangers to many countries as part of the construction of power plants.
The electric heater, which is a heat exchanger, of Quiri thermal design, heats the fuel oil through an electric immersion heater to obtain the required viscosity at the inlet of the turbine.

Geometric specificities:
Horizontal heat exchanger, overall length 4 m, empty weight 2 tons.
Construction Specificities:
Code : ASME VIII Div.1 + TEMA R
Regulation: PED 2014/68 / EU and/or U STAMP
Joint efficiency : 0.85
We also fit isolation, drain and vent valves on these electric heaters.
We also install thermometers, safety valve as well as temperature probes allowing the regulation of the heating power. A safety thermocouple is also installed in contact with the skin of the immersion heater in order to guarantee a maximum skin temperature.
A system of recovery tank is also installed in order to recover any fuel leaks.
We also carry out the electric heat tracing as well as the thermal insulation of these exchangers.
We also carry out the wiring of the instrumentation which we centralize on an electrical box.
We produce fuel heaters with a single immersion heater or with multiple immersion heaters according to the desired customer regulation (see photos below).
