Sprung hatch seals need to maintain the internal pressure during the start up and powering down of boilers. Any leaks due to a reduction of pressure on seals are automatically prevented by a set of external spring KSD ‘Premium’ hatch seals are guaranteed safe and durable
The seal systems are planned according the the Client’s specific needs and can be installed by a KSD service team upon request.
The seal systems are located in the power shunts. With the reduced width relative to a standard seal, the pressure tolerated is increased because of it smaller surface area . The double-T bar prevents to great a pressure being applied upon the seal.
After the opening of the hatch the supporting double-T bar can be re-used, however the seal needs to be replaced. The seal itself is flexible and adjusts the applied surface. The seal available are round, oval or angular.
The primary aim of the MICA program is to block out oxygen by means its protective clear graphite layer. By the preliminary switching on of the blocking sphere, neutral conditions arise in the seal globes
The closed blocking is preliminarily switched on on the side which is to be protected. With collar seals the following combinations are possible:
