AET Biomass Cogeneration Plant

AET designs and supplies turnkey biomass cogeneration (CHP) plants with excellent and well-documented performance and availability.

The benefits of an AET cogeneration plant include:

  • The unique AET Combustion System
    » Low flue gas emissions,
    » High combustion efficiency,
    » Low in-house power consumption
    » Best Available Technology
  • High fuel flexibility
    » Lower operating costs
  • High boiler and plant efficiency
    » Optimised heat balance
    » Good customer business case
  • High availability
    » Improved customer business case

Determining the optimal design for a biomass fired combined heat and power plant involves factoring in many different parameters such as optimal operating conditions, fuel, boiler, turbine, steam/water cycle, heat requirements etc.

AET can assist you to optimise the plant parameters as our expert employees have many years of experience and extensive knowledge of steam cycles, boiler systems and steam turbines.

 

AET Biomass Cogeneration Plant parameters

 

The AET combined heat and power (CHP) plants can be designed for all types of biomass. The high efficiency, very stable electricity production and extremely high availability ensure a good business case for you as the investor. The design parameters below form the basic platform for our plants:

 

Fuel heat input

25 – 170 MWth

Net electrical power output

7 - 60 MWe

Net plant efficiency

45 - 90 % depending on steam requirements and process integration
70 - 105 % depending on district heating requirements and process integration

Boiler design

Water tube boiler with natural circulation
Single pressure or double pressure (reheat, e.g. 140 bar and 25 bar)

Operating time

At least 8000 hours without shutdown for manual cleaning

Boiler efficiency

91% - 94% depending on fuel moisture

Emission values

Better than European requirements (large boiler or WID)

Fuel flexibility

Fuel moisture content: 10 - 55 %

Auxiliary burner

Not necessary

In house power consumption

< 2.5% of fuel heat input

Availability

Better than 96 %
