MMS Ltd installed new inline sludge traps and high capacity magnetic filters to 6 MTHW Boiler houses at LS Donnington nr Telford.

During the annual summer shutdown of the heating systems at LS Donnington MMS had identified that iron oxide sludges and scale had accumulated within the aged MTHW pipework systems. MMS were tasked with finding a solution to these problems which had caused in a number of boiler outages during the previous heating season. As brand new boilers were scheduled to be installed it was imperative that these would be adequately protected from being contaminated by existing deposits from the old & extensive distribution systems.

A number of chemical water cleaning / pressure flushing scenarios were considered from a technical and commercial perspective. Due to extent and age of the existing distribution systems passive separation measures were selected as the preferred solution, backed up by chemical cleaning and flushing of the existing boiler house circuits.

MMS designed and installed high capacity sludge traps in the common return pipework entering each Boiler house as a primary protection, with secondary protection to the boilers provided via a high capacity magnetic filter system to remove any remaining fine particles before they entered the new boilers.

The complete installation was implemented on time, within budget, and with minimal disruption to the site, services and occupants.

There were zero accidents and no reportable near misses.

To date the new boiler installations have performed with a 100% reliability record since completion.
