Mokesys Air - Model 2E - Rear-Ventilated Tiling Systems

The rear-ventilated tiling systems offer effective protection from corrosion due to the circulating air behind the tiles. The heat extraction can therefore be individually tailored by adjusting the stud fixings. The Mokesys^® Air 2E is used in the first boiler pass. It comprises nitride bonded SiC tiles and a layer of constantly circulating air which is created by an external supply system. The newly developed Mokesys^® Air UHS, for which a patent is pending, offers permanent protection for superheater bulkheads in the second pass. Small amounts of air are blown, at low pressure, between the superheater’s tubes and the Mokesys^® Air UHS tiles. The circulating air provides ideal protection against corrosive flue gases.

Mokesys Air - Model UHS - Rear-Ventilated Tiling System

Alongside the existing Mokesys® Air system, which is used in the first pass, the new Mokesys® Air UHS offers long-term protection for superheaters in the second pass. As with all Mokesys® tube wall protection systems, this one also comprises premium-quality SiC tiles and their fixings. It is ingeniously simple to operate: at low pressure, small quantities of air are blown in between the superheater tube wall and the Mokesys® Air UHS tiles. The air which thus circulates affords optimal protection against corrosion. A further major advantage is that Mokesys® Air UHS tiles can be installed easily and quickly, thus saving valuable time during construction or dismantling in comparison with conventional methods of protection for superheaters. The result is a customised refractory lining which retains a high degree of flexibility over a long period of time and thus significantly extends the system’s disruption-free operation.
