To minimise
heat loss from the boiler and to prevent the ingress of rain water,
Damper Technology Ltd have a range of stack isolating dampers which
are designed for use with stacks from 300mm dia to in excess of
7m diameter.
The
stack isolating damper can be of the butterfly, twin louvre, multilouvre
or twin flap design and can incorporate an automatic pressure relieving
system to prevent over pressurisation and damage to the turbine.
