In assembly in Mexico, this Steam Generator counts with dry gas cleaning system, with CSC (Caldema Sand Collector) for protection against economizer and air preheater wear and tear multicycle and ESP (Electrostatic Precipitator). At the ashes will be dry removed and packed in a silo with 12 hours of residence time. Guaranteed emission of particulate matter on exit of gases is 100 mg / Nm³ at 6% O2. The project is ready for operation with regenerative cycle and water temperatures at 160ºC and air at 80ºC.
