Aalborg Energie Technik a/s (AET) Biomass Co-generation Plant:

Boehringer Ingelheim Pharma KG, Germany

In 2004, the pharmaceutical company Boehringer Ingelheim Pharma in Ingelheim wanted to change the fuel from coal to waste wood for an existing boiler plant.

The CHP plant was originally built as a 100% coal fired travelling grate unit for the supply of electricity and process heat to the pharmaceutical process. The cogeneration plant was originally commissioned in 1983.
 

Redesigned for 100% biomass

In 2004, the boiler was re-commissioned after conversion to 100% biomass and redesigned to AET Combustion System where possible and feasible.

The CHP plant was redesigned to burn demolition wood (A1 - A4)  in accordance with the requirements of the German WID.
 

A ChlorOut system has also been implemented via the AET SNCR DeNOx System in order to minimise fouling and corrosion at the last stage of the superheater. The ChlorOut system is rather advanced, as it is a two-step injection with dedicated sulphate liquids in order to reach a certain KCl level and reduction of emissions. The KCl level is monitored by an in-situ Alkali Chloride Monitor (IACM).

 

AET supply

In connection with the conversion, AET has designed, engineered, procured and supplied the following:

  • Fuel dosing system
  • AET spreader stokers
  • Modification of furnace and superheater
  • Gas burners
  • AET combustion air system
  • Modification of flue gas and flue gas recirculation system
  • AET SNCR DeNOx system integrated with ChlorOut system
  • Flue gas cleaning with absorbent injection system
  • Modification of ash handling system
  • Modification of carbon re-injection system
  • Mechanical erection
  • Electrical systems
  • Instrumentation
  • Engineering of PLC control
