Quenches / Saturators

Properties and possible applications of quenches


  • self-priming
  • applicable up to 1200° Celsius (special designs for higher temperatures available)
  • co-current flow operation
  • Fluctuations in flow permissible over a wide range
  • no pressure loss
  • insensitive to caking and incrustations
  • high solids load possible
  • can be integrated into pipelines
  • low space requirement
  • inexpensive
  • Version without internals available
  • Combination with absorber possible


Possible applications of quenches:

  • direct gas cooling
  • Saturation / Pre-saturation
  • Combination of cooling, absorption and dust

Monitoring systems for triggering emergency cooling

As a rule, quenches are not constructed entirely from temperature-resistant materials (e.g. Hastelloy or tantalum), but also from materials such as PP/GF-UP or steel/rubberised, for reasons of cost or material properties (corrosion, etc.). However, both subquantities (blockages, defective pump) and overquantities (nozzles worn out, torn off) in the liquid supply can lead to unacceptably high temperatures, which then lead to damage to the quench. These damages can be avoided by using a suitable monitoring system.
The following monitoring options exist and are used for specific applications:

  • Individual monitoring of nozzles with flow (FZA +/-)
  • Monitoring of the partial flow required for cooling (FIZA +/-)
  • Monitoring of the motor current consumption of the pump (EIZA +/-)
  • Gas temperature monitoring (TIZA +/-)

For critical cases, several monitoring options are also combined. VUM advises you in your individual case and provides the optimal monitoring system. There is also a monitoring system available to ensure the emergency water supply. The picture shows a quench, through which the exhaust gases of a process air combustion are disposed. In addition to monitoring the entire volume flow, relevant process nozzles are also monitored individually to ensure that there is no shortage. This system represents an optimal concept for medium-sized designs.
