Equipment For Reducing Particulate Atmosphere

MOIST SOOT RETAINERS: 

Caldema’s moist soot retainers provide the best retention of particles when water is available, as in industries of sugar and alcohol. Its optimized design allows efficiencies up to 95%, with reduced water consumption. The cleaning water is recirculated, requiring only a small replacement due to evaporation. The supplied materials and design developed based on the experience of several facilities in operation result in high durability of the equipment and low pressure drop in the flue gas. 

This low pressure drop, coupled with the reduction of the gas temperature, resulting in low power consumption in the extractors. It can be installed one of the gas temperature control after the washer for better operation in any boiler load conditions and ambient temperature. 


Multi-cyclones: 

The multi-cyclones appear as the best solution when the client cannot have water and space required for use of the wet seals. It should also be used when the emission limits require higher retention efficiencies than 95%. In this case a multi - cyclone can be installed before the wet soot retainer. The designs developed by Caldema and their partners have low pressure drop - 50 mmca - and high durability due to the use of high hardness cyclones.
