Monsal concentric tube heat exchangers are designed for heating sludge and organic waste in the anaerobic digestion process. Large inner tubes, 80-150 mm in diameter are used to eliminate blocking and allow heating of thick sludges to over 10% dry solids content.
Monsal heat exchanger packages can also be provided to suit individual projects. These heat exchanger modules with integral Monsal Controllers are available skid-mounted and fully piped-up. The pre-assembled modules facilitate fast track installation and commissioning. These heat exchanger products are suitable for incorporation with heat recovery loops including CHP and thermal drier applications. Monsal Controllers ensure accurate temperature control to ± 1oC.
Monsal heat exchangers are manufactured to ISO 9001:2008 standard and are available in carbon or stainless steel. Hardened pipe work and bends can be specified for high abrasion or grit applications. Standard heat exchangers are available in 6.0 m and 3.0 m tube lengths, but products can be manufactured to suit most requirements.
Advantages:
- Purpose-designed water jackets give optimal liquid velocity and heat transfer.
- Available in units from 50 to 3,000 kW as standard.
- Heating of thick sludges – to over 10% dry solids content.
- Suitable for mesophilic and thermophilic duties.
- Monsal Steam Ejector Heat Exchangers are especially suited for advanced digestion processes including thermophilic digestion, Enzymic Hydrolysis, thermal hydrolysis, and specialist applications where there is a higher risk of heat exchanger fouling.
Steam Ejector – Heat Exchangers
Monsal Steam Ejector Heat Exchangers are suitable for high heat transfer duties for thick sludges and slurries. Monsal Steam Ejector Heat Exchangers come as completely assembly products with integrated control systems.
Monsal Steam Ejector Heat Exchangers are suited for very thick sludges and can be provided with high pressure and depressurization systems to increase the levels of solids destruction in the digestion process.
