RTO maintenance

Maintenance of RTO & RCO systems

Solutions for energy and environmentally optimised operation.

APPLICATIONS

Solutions for routine and general maintenance of RTO & RCO systems.

REFERENCE APPLICATIONS:

During the operation of regenerative thermal oxidizers (RNV/RTO), combustion residues are deposited on the honeycomb ceramic elements. These deposits reduce the performance of RTO & RCO systems. Therefore, the honeycombs need to be cleaned regularly and replaced if necessary.

APPLICATIONS BY INDUSTRY:

  1. paint shops (incineration of basecoats …),
  2. production of polyurethane foam (pulverization of release agents),
  3. production of batteries (manufacture of electrical circuits),
  4. cement manufacturing plants (NO deposits in kilns and exchangers …).

WE CLEAN:

  1. volatile organic compounds (VOC),
  2. ammonia (NH3),
  3. hydrogen sulfide (HS2),
  4. polycyclic aromatic hydrocarbons,
    (PAH),
  5. nitric oxide (NOx),
  6. polychlorinated dibenzodioxins (PCDD/F),
  7. dust,
  8. carbon monoxide (CO),
  9. hydrogen cyanide (HCN),
  10. carbon disulphide / carbon sulphide (CS2/
    COS).

Advantages - maintenance of RTO and RCO systems

Up to 30% higher energy efficiency of RTO & RCO systems and lower emissions.

Important:

REDUCED ENERGY CONSUMPTION: a multi-stage blowing and non-abrasive cleaning process ensures up to 30% better flows and energy efficiency

WE ADHERE TO STANDARDS AND PROTOCOLS: all our maintenance work and procedures are conducted in accordance with the standards and protocols of equipment manufacturers and our customers

WE ALSO CLEAN HARD-TO-REACH PLACES: we have developed a proprietary system for cleaning hard-to-reach places, which are inspected with a camera after the procedure

Manual cleaning (above) and system for cleaning hard-to-reach places in small cross-section combustion chambers (below).

THE EQUIPMENT REMAINS INTACT: we execute the maintenance operations safely, with no damage to the ceramic cores or equipment (flaps, impellers, cabling, compressed air …)

WATER- AND CHEMICALS-FREE: we use a completely dry cleaning process to clean the incinerators, so you can run the equipment immediately after the maintenance.

SHORTER DOWNTIME: we organize work in 2 or more workshifts and thus ensure the shortest possible downtime of your equipment.

DRY ICE CLEANING

For EFFICIENT CLEANING WITHOUT DAMAGING the ceramics or other parts of equipment (flaps, valves, electronics, compressed air installations …), we use the dry ice cleaning technology.

It is a completely COMPLETELY DRY cleaning process. After the cleaning, the units can be RUN IMMEDIATELY for up to 30% LESS DOWNTIME of your incinerators.

BLASTING AND PAINTING

In the phase of restoration works on internal and external structural parts of a RTO unit, we perform a comprehensive restoration of surfaces. Blasting removes the rust, old paint and dirt, and roughens the surface for excellent paint adhesion. For painting we work with different application systems (manual, gun, airless …) and paints according to customer requirements.

CERAMICS REPLACEMENT

In scope of general overhaul, we perform the disassembly, cleaning and, if necessary, replacement of ceramic packing (“saddles”, ceramic blocks) according to the standards and protocols of incinerator manufacturers.

We use quick-assembly conveyor belts for fast and safe transport.

opinions of our customers

Routine maintenance and cleaning of RTO systems in the paint shop is a prerequisite for reliable operation and optimal energy efficiency. In such projects, one needs a flexible partner who respects your schedule and technical requirements ... Blast Tehnik has proven to be a reliable long-term partner with whom we have successfully carried out more than 30 cleaning interventions and other service operations on our RTO unit.
