School Heating Renovation

application area: commercial gas heating

use type: condensing gas boilers

project scope: line commercial freestanding chimney for condensing operation

added value: corrosion-resistant, air-tight and waterproof finish

Background

The combustion gases from the school's boiler room are exhausted through a freestanding 28-metre brick chimney. The structure was not suitable for the wet operation of condensing boilers. FuranFlex-25 Black was the chosen lining material.

The new boiler plant required a 500mm diameter flue liner but the chimney could not accommodate a rigid liner this size. A FuranFlex25 Black liner was therefore specified as it expands into the rectangular flue shape when inflated with steam.

Statement of work

FuranFlex25 comes as a folded and soft tube. Inflating with steam irreversably hardens the liner fixing it in place. Within a few hours of steaming the liner was ready for connecting to the boilers. The appropriate adaptors/terminals were fitted making the chimney ready for operation.
