Stack Busch
BML Stack busch are designed to minimise heat loss from your boiler and to prevent the ingress of rain water. Our stack isolating busch are bespoke so can be designed for use with any exhaust stack in the range of 300mm – 8000mm Diameter.
A stack damper can be supplied as either a butterfly or multilouvre design and will typically incorporate an automatic pressure relieving system which opens the blades in the event of unexpected pressure spikes. Opening the blades therefore prevents over pressurisation and subsequent damage to the HRSG and gas turbine.
An optional drain channel built into the central beam of the framework provides weather protection by channelling rain water from the blades out to a dedicated drain point on the side of the damper, therefore protecting the boiler.
BML Stack Busch are also referred to as a Weather Protection Busch or Rain Busch are generally manufactured in Carbon Steel or Stainless steel. However, for special applications we can utilise any material to suit your requirements such as 800HT, 310S, Alloy 31, Alloy 59…
Our stack busch are often supplied with electric actuation, but can also be provided with pneumatic or manual operating systems. All actuation systems are flexible so can be supplied to operate locally, remotely, or from floor level.
