Temperature control

Water cooling can be achieved by direct channel injection for simpler applications, or with quenching towers using atomisation and complete evaporation. The injection nozzles used can be of the spill-back or twin-fluid type and can operate with upward or downward flow, depending on the specific requirements of the process.

The water used for cooling can be process water, thus contributing to the reduction of liquid purging in the system. Area Impianti is recognised for its expertise in implementing water cooling solutions in a wide range of sectors, ensuring efficiency and reliability.

Heat exchangers are an ideal and very flexible solution for various sectors. Their application limits flow rates, allowing lower sizing of the downstream equipment.

Thanks to specific design details, the proposed cooling/heating systems can also function as reactors or be integrated into the process.

Area Impianti uses tubular or plate heat exchangers, ideal for high dust levels. Cleaning is made easier by a design that has been optimised over the years, equipped, where necessary, with chain or compressed air systems with solid references.

These systems can be used for:

• Flue gas/air or flue gas/flue gas heat exchange
• Flue gas/water or oil heat exchange
• Flue gas/flue gas heat recovery
• Condensate preheating
• ORC (Organic Rankine Cycle)

The extracted dusts and ashes, often hygroscopic and complex to handle, indeed require the in-depth knowledge that we have refined over time.

Dust is stored in silos with automatic filtration systems to ensure compliance with emission limits. For transport, we use both mechanical and pneumatic technologies. Mechanical solutions include closed chain conveyors (redler), screw conveyors and bucket elevators for vertical sections. For biomass and combustion residues we use conveyor belts.

We are ready to work with our customers to design and implement the most effective dust management solutions.
