Emergency cooling
▀
In accordance with the EN303-5 standard the boiler is tested with a emergency cooling coil.
When firing solid fuels in a pressurized system it is at all times recommended to use the cooling
coil. The quench valves SYR 3065 and 5067 makes it possible for closed plants to be used
with solid fuels, for example wood, chips or turf. There are two different sytems for emergency
cooling of the boiler. Either direct injection in the boiler (5067) or with the coil that is placed on
the top of the boiler (3065).
Without emergency cooling
The quench valve (5067) serves as a temperature controller
for boilers in open or closed plants that are fired with solid
fuels and is not equipped with cooling coil. The valve is
mounted on the hottest place, the flow pipe(1). Incoming
coldwater is connected to the return pipe (2) and the
cooled water is connected through the valve on the flow
pipe (3). The cooled water is then led down to a floor drain
or another outlet that can stand high tempertures.
With emergency cooling
The quench valve (3065) serves as a temperature controller
for boilers in open or closed plants that are fired with solid
fuels and are equipped with a cooling coil. The valve is
mounted in the thermowell on the top of the boiler(1). The
cold water is connected through the valve in the cooling
coil. The cooled water is then led down to a floor drain or
another outlet that can stand high tempertures.
