How important is it?
The film temperature is an important parameter in the design of the boiler. The durability of the boiler and the installation dependent on this one.
It is defined as the oil temperature at the inner surface of the coil tubes. The DIN 4754 standard provides its calculation. The most important parameters are:
- Oil type.
- Oil speed.
- Dimensions of the coil.
- Dimensions of the combustion chamber.
- Heat flux.
- Type of fuel.
This temperature should be low, uniform and stable.
