Your Water Seal Trough Problem

Wire mesh screens and the fiery intensity of your bottom ash hopper – it just doesn’t seem to be a fair fight.
Refractory poured castings, an original OEM type of expansion joint protection, are extremely heavy with no flexibility to absorb clinker impact. Refractory chips and falls out of the castings quickly after installation, leaving your seal skirt and trough unprotected. Once screens or castings have failed, your seal skirt is directly impacted by radiant heat from the boiler and bottom ash hopper.
Maintenance shutdowns are typically extended to repair or replace damaged wire mesh screens or castings. Longer outages result in higher labor costs and replacement material expense.
There should be a better product for the protection of the entire expansion joint in a bottom ash hopper.
