CMS Emergency Repair Services

In many cases, boiler operators are forced to de-rate their plants due precisely to air pre-heater leakage and fouling. Statistics from the NERC GADS database demonstrate that between 2007 and 2011 a total of 3,233,636 MWH of forced de-rates were lost due to ‘Combustion Air & Gas Causes’. If a generating unit can no longer attain the desired generation at the boiler or unit maximum capability rating (MCS) this reduces sales revenue at a time when the value for energy is the highest.

At CMS, we pride ourselves on our ability to react at a moment’s notice and help our clients regain capacity. The ability to mobilize and complete complex repairs on an emergency basis within a ridged timeframe is a core competence at CMS. We understand the financial implications at stake and through decades of experience we have learned to prepare for the unexpected. CMS maintains over a million liner feet of steel at our fabrication facility for precise purpose of responding to the needs of your emergency.
