2.6.1 Devices for preventing the boiler from overheating
Thermal discharge safety device
At around 100 °C a valve opens and sends cold water to the safety
heat-exchanger to decrease the temperature.
Safety Temperature Limiter STL
Stops combustion at a max. boiler temperature of 105 °C. The pumps
continue to run.
 Once the temperature has fallen below the unlocking point (approx.
95 °C), the safety temperature limiter (2) can be unlocked
mechanically.
Safety valve (provided by the customer)
Protection against over-heating/ excessive pressure:
When the boiler pressure reaches a maximum of 3 bar, the safety valve
opens and the heating water is released in the form of steam.
