SAFETY AND CONTROL
Safety measures have been taken in case the used steam exceeds the maximum operating temperature and
pressure. These are;
Safety Switch
If the device is single-stage, it has one operating and one safety switch. The safety switch turns the burner on or off
according to the pressure it takes from the produced steam. If this operating switch fails to function for any reason,
the safety switch is activated. This switch is set 1 bar above the set value of the operating switch. Stops burner when
activated.
Flow Switch
In SHS type steam generators, flow switch is used to control the water flow on the feed water line. The task of the
device is to determine whether there is any water supply to the system due to any failure in the feed water
pumps and to stop the system completely.
Steam Thermostat
There is a steam thermostat which continuously measures the steam
temperatures during operation. The steam has a corresponding
temperature with pressure. The system automatically shuts down
when the current steam temperature reaches the limit temperature
set on the steam temperature line on the electric control panel.
Safety Valve
The safety valve is set at 1 bar above the working pressure of the safety switch. This
process is carried out during the manufacturing stage of the device. When the safety
switch does not work, the steam pressure in the generator increases as the burner will
continue to burn. When the operating pressure reaches the safety valve setpoint, it
relieves excess steam and balances the pressure.
Smokestack Thermostat
The system automatically stops as
soon
temperature exceeds the set value.
