  • SAACKE rotary atomising technology

  • The basis of the SAACKE rotary atomising technology is the multi-stage rotation and air atomisation with thermal support. The result of this technology is a very fine oil atomisation with a narrow homogeneous droplet spectrum and a constantly high quality throughout the entire wide control range. The combustion process is optimally controlled, since the combustion air is distributed as primary, secondary and tertiary air.
  • The essential part of the rotary cup atomiser is the rotating atomising cup. The liquid fuel is supplied to this cup almost without any pressure. The centrifugal forces produced by the cup’s rotation, draw a wafer-thin homogenous and closed oil film. This film is then uniformly distributed on the inside of the cup. When the oil film leaves the cup’s rim, the existing surface tension makes that it is widened up into an extremely fine film mist. The primary air emerging with a high kinetic energy concentrically around the cup rim now carries out the final and essential part of the atomisation.
  • The new rotary cup atomiser ist he central component of the SKV(G)-A that brings the well-proved SAACKE rotary atomising technology to a new dimension of performance. The rotary cup atomiser is equipped with a totally new drive system whose most important feature is its exceptional mechanical load factor – the precondition fort he high rotary cup atomising cup speed of 6,500 rpm. The new concept of the poly-V drive and the maintenance-free, with high-capacity EP-grease permanent-lubricated bearings both guarantee the SAACKE typical reliability and long service life. The high speed realises an ideal droplet spectrum with the largest possible atomising potential for optimum firing sequence. The result: a combustion that could not be more economic and low in pollutants, even when operating with extra heavy fuel oils. No other burner system is of comparatively efficient performance.

  • Oil safety shut-off valves

  • The SKV-A represents a new safety standard in burner technology. One of the most innovative components is its ZV central valve. It is of fundamentally new design, long-term tested and type-approved. The sealing is located directly in the rotary atomising cup thus avoiding any further fuel flow after the burner is stopped. In heavy fuel oil design, the valve is heated up the valve cone assuring immediate readiness for operation even after a long burner standstill. Post-purging with light fuel oil or blowing out of the oil transporting piping is not required.
  • In contrast to the pre-controlled valves, the directly controlled ZV has no narrow control holes thus assuring the best possible safety even for operation of extra-heavy fuels under the hardest service conditions.

  • SAACKE gas burner technology

  • The newly developed low NOx gas burner of type SG-A or SKVG-A realises cross-flow mixing of the fuel gas with combustion air and thus may be easily adapted to different gases. The gas is led to the furnace by means of 4 specially designed and easily exchangeable nozzle bores thus generating fuel-rich and fuel-poor zones within the furnace. A small portion (primary gas) forms an extremely stable core flame in the stabilising plate area. The result of this “staging¨ is a complete and low-noise combustion with very low NOx emissions.
  • The combustion air of the SG-A and the SKVG-A burner is guided to the combustion process by 3 individually adjustable partial streams. This allows quick commissioning at different firing plants and hot gas generators.

  • The result: optimum combustion.
