Targeted cleaning

CTP environnement has developed a range of cleaning solutions specifically designed for cogeneration heat exchangers, for the flue gas side.

Although the majority of cogeneration plants burn clean gas, the oils and greases used to lubricate moving parts break down at high temperatures and contaminate the vapour, which creates a fouling on the downstream heat exchange surfaces (whether these are finned or tubular).

A beneficial application

The nominal operating characteristics of heat exchangers are restored, with specifically:

  • An improvement in heat transfer and efficiency
  • A reduction in the quantity of fuel and CO2 emissions

When performed regularly, these operations ensure the long-term sustainability of equipment and maintain the energy efficiency that is the basic principle of cogeneration.

Processes tailored to the design of heat exchangers

CTP environnement has a choice of two methods, combining mechanics and chemistry, which cover all kinds of cogeneration heat exchangers:

  • Rotary jet cleaning is suitable for intra-tube cleaning: the combined action of the chemical degreaser, the temperature and the jet pressure enable residues to be removed. Each tube is treated individually to ensure completely consistent results.
  • The high-pressure spraying process is suitable for deep cleaning finned tubes: the powerful degreaser applied using a fan nozzle reaches beyond the most accessible tubes, guaranteeing a 100% uniform result, which is conducive to the right heat transfer balance.
