ENSURING RELIABILITY AND UPTIME
Controlled humidity means greater reliability
Humidity challenges in power generation plants
Water, airborne moisture and steam are often present in modern power plants – both large and small. The high levels of humidity that result from this can easily give rise to a wide range of problems and operating glitches stemming from corrosion, condensation and rust in – and on – turbines, boilers, reactors and other generating equipment, as well as piping, support structures and other installations.
Temperature differences between hot or cold materials and the surrounding air provide a good basis for airborne moisture condensing and pooling. This then results in corrosion of metal surfaces and components as well as having negative effects on mechanicals and electronics. All this can then impact both operational availability and generator-set reliability.
All these in turn impacts uptime, generating capacity and operating costs, adding a level of risk decidedly unwelcome in an industry where KPIs, profits and reputation depend heavily on reliability.
Tackling the problem
When equipment is big, expensive and operations-critical, it pays to keep it in best possible condition. Prevention is a whole lot cheaper than cure – be it mopping up or repairs.
Equipment and machinery inside power plants requires reliable protection against airborne humidity. In many cases, this involves blowing dry air into the equipment in order to hinder the onset of any problems stemming from condensation and resulting corrosion of metal components and surfaces.
In energy generation plants powered by gas turbines, considerable volumes of air are required, and the output as well as the fuel bills depend heavily on the specifications of the air flow into the combustion chamber.
Cotes dehumidifiers help you improve the quality of the air passing into – or inside – your turbines, generator sets and boilers. Better air specs, including controlled removal of airborne moisture and any suspended corrosive salts, add up to less risk, longer service life and lower operating costs.
Cotes dehumidifiers make it easier to completely prevent corrosion condensation and issues of this kind by controlling the point at which the inevitable water vapour in the air inside your power plant condenses (the dew point). The basic laws of physics mean corrosion simply cannot occur if relative humidity is kept below 65% at 20oC.
