Boiler Cleaning

airmaxx is a boiler cleaning system for automatic cleaning for heat recovery systems/ waste heat boilers.

The boiler cleaning system airmaxx is suitable for the removal of loose or lightly adhering deposits / soot on the heating surfaces of heat recovery systems. This cleaning will be effected with compressed air via cleaning nozzle. The cleaning medium passes through a heat-resistant stainless steel hose with the aid of special locks between the passes of the heating surfaces to be cleaned. Variables tangential blowing off the heating surfaces ensures a uniform cleaning of the coiled tube in the waste heat boiler / heat exchanger. The Airmaxx belongs to the family of soot removers and has been specially developed and patented at biomass combustion for the heat recovery systems.

The function of the boiler cleaning system differs from previously used concepts in particular in that, the cleaning medium (usually compressed air) is brought very close to the heating surface to be cleaned. In this way, a very good cleaning effect is achieved already at relatively low pressures and quantities of compressed air. Moreover, the heating surfaces are not constantly blown in the same place by the pressure beam, so the risk of erosion was almost eliminated. Another advantage is the reduced piping effort, since the compressed air is attached only at one point.

Advantages

  • Reduced energy consumption and improved cleaning efficiency
  • Easy maintenance
  • The cleaning medium is released where it is needed and ensures optimum results with low energy consumption
  • Optimal cleaning effect no matter what design or size of the heating surface
  • All relevant operating parameters are evaluated continuously
  • The system can be easily integrated and installed in already existing plants
  • Programmable and repeatable cleaning cycles
  • The laser-based positioning ensures exact cleaning
  • Minimized wear and tear of the heating surfaces

Increasing the efficiency of combustion plants with heat recovery systems

Combustion installations with heat recovery systems and heat exchangers required a long and uninterrupted time of operation. Most realized modulating operation in various part load conditions draws altered amounts of exhaust gas. In the same way, the exhaust gas velocity in the alleys of the waste heat boiler and thus the self-cleaning effect is changed. This causes the formation of increased deposits/soot on the heating surfaces in the partial load ranges, leading to a reduced heat transfer, thus to lower efficiency of the heat recovery systems. Particularly high demands provide plants to generate heat and / or electricity generation by using biomass and other solids.

The airmaxx cleaning system for heat recovery systems is designed specifically for high performance in these areas and cleans the heating surfaces fully automatic, intelligent and while the plant is operating.
Increasing cost pressures by staff and fuel supply at constant revenue situation pushing for optimized system solutions with long travel times and minimum maintenance. This cost pressure makes fully automatic and reliable solutions necessary. Maxxtec developed and manufactures for many years successfully automatic cleaning systems for heating surfaces of heat exchangers and heat recovery systems.

The airmaxx boiler cleaning system for heating surfaces of heat exchangers and heat recovery systems is the result of years of experience and extensive research of Maxxtec development engineers and applied for a patent. With its innovative technical concept, it ensures that at a substantially improved cleaning efficiency at the same time the energy required for the generation of compressed air can be reduced.
