ST-707 Rotations Control
Rotations Control is a regulator with a continuous output signal, using
PID regulation algorithm
. In this type of controller the blow-in power
is calculated on the basis of the measurement of the boiler temperature
and the temperature of flue gas measured on the boiler's outlet.
Operation of the fan proceeds on an ongoing basis and the blow-in power
depends directly on the measured boiler temperature, the temperature of
flue gas and the difference of these parameters from their preset values.
Stable maintenance of the set temperature without any unnecessary
adjustments and oscillations are the advantages of the zPID regulator.
Each controller should be set individually, for own needs, depending
on the type of fuel used for burning as well as the type of the boiler. The
TECH company will not be liable for any incorrect settings of the
controller.
When using this type of controller with a flue gas outlet sensor,
savings in fuel combustion may reach up to more than ten percent; The
outlet water temperature is very stable, which affects the longer life span
of the exchanger (boiler). Checking the temperature of flue gas at the
outlet from the boiler causes low emission of dusts and gases harmful for
the environment. Thermal energy from the flue gas is not wasted and
released to the chimney, but used for heating.
