Clean Technology Products

With its Clean Technology solutions, KHD Humboldt Wedag offers innovative products and services that are not only energy efficient but also environmentally friendly.

We were the first to introduce many developments in the cement industry, including the world’s first pre-heater tower and, more recently, our energy efficient COMFLEX® modular grinding system. Our PYRO-JET® Burners and PYROCLON® R Calciner with combustion chamber allow for high input of many alternative fuels. Notably, KHD is an industry leader in calcining technology with low NOX. Also, our state of the art pyroprocessing equipment requires less heat for the process, which helps avoid producing additional unnecessary CO2.

For cement plants, KHD offers:

  • Full line engineering and equipment supply
  • Individual Machines
  • Equipment Packages
  • Spare parts & the full range of plant services

Preheater

In the early fifties there was a technical revolution. KHD built the first Preheater (Germany, Bomke & Bleckmann), a starting point of a new aera of reducing the heat consumption of the clinker pyro-processing system by nearly 50% at this time.
Features
  • 270° inlet spiral with improved inlet geometry
  • An optimum of separation efficiency and pressure drop is obtained by properly dimensioned immersion tube, separation efficiency of top stage approx. 95%
  • Steep cones to minimize coating tendency
  • Low gas flow velocities in the immersion tubes between 10 and 15 m/s
Benefits
  • The raw meal processed in the kiln first passes through the preheater absorbing the heat content of the kiln and PYROCLON® gases minimizing the heat consumption of the system.

  • KHD Preheaters with modern designed cyclones produce low pressure drops and are high in separation efficiency.

  • The resulting low waste gas temperatures lead to reduced heat losses, waste gas quantitites, CO2 emissions, dust emissions and electrical energy consumption.

The standard calciner for oil and gas is the PYROCLON®-R with PYROTOP® compact swirl chamber. The PYROCLON®-R LowNOx with PYROTOP® is the standard calciner for using solid fuels. Both calciners have proved their capabilities of reaching emission limits of worldwide legislation without the use of additives.

PYROCLON Low NOx AF Calciner

Nunc iaculis nisi suscipit euismod semper. Donec placerat ante sed erat commodo finibus vitae quis est. Nam vitae varius velit. Fusce elementum ante erat, at faucibus ante euismod vel. Sed pretium dui sem.
Features
  • Staged combustion
  • Low cost NOx-reduction without additives (SNCR process)
  • High efficiency and flexibility
  • >40 references
  • BAT “Best Available Technique”
  • Emission level: <500mg NO2/Nm3with gas, oil, lignite and most kind of coals
Benefits
  • The reducing gas strand from the Low NOx zone is united with the oxidizing gas strand and later intensely mixed in the PYROTOP® compact swirl chamber. Due to this turbulent mixing, the remaining CO oxidizes to CO2 with the oxygen present in the gas stream. The use of lumpy secondary fuel or fuels characterized by poor ignitability becomes possible by additional installation of a combustion chamber equipped with a “hot spot” burner. Depending on the physical and chemical properties of the secondary fuels, up to 100 percent of the fuel required in the calciner can be substituted.
