ENERGY FROM WASTE HEAT
According to the Federal Environment Agency, the “final energy consumption” (EEV) for heating and cooling accounts for a good half of the total final energy consumption in Germany. Process heat alone accounts for a good 20% of the EEV.
The term process heat refers to heat that is used in commercial and industrial processes to change raw materials or workpieces, for example for production or central production processes such as casting, hardening, firing or drying processes. From part of the process heat that is not used for the manufacture, production or processing of waste heat, we convert energy into electricity.
With 66% of total industrial energy consumption , process heat is the most important commercial energy input, with heat and cold being required for different areas of application.
Share of process heat from total industrial energy consumption
Retail, Commerce, Services
In the areas of trade, commerce and services, almost 60% of the total final energy consumption is used for heating applications.
In the processing and manufacturing industries, process heat also has the largest share of final energy consumption at almost 60%.
BENEFITS OF ENERGY FROM WASTE HEAT
Our energy is becoming more and more valuable as resources become scarcer. In the future, use your unused energy from production, manufacture or other processes and convert it into electricity . In this way you will significantly reduce your energy costs and at the same time protect the environment.
Use the waste heat from your production to generate clean electricity. You also need less gas or oil and thus use fewer resources and reduce your company’s CO 2 emissions.
Thanks to the efficient use of waste heat, there is no need to install an additional plant for heat generation. Together with you, we improve what is already there – your waste heat.
INEFFICIENTLY USED RESOURCES
Power generation from waste heat from the metal production and processing industry
Conversion of waste heat from the chemical industry or mechanical engineering into electricity
Generating energy from unused gaseous waste
Conversion of waste heat from pyrolysis processes into electricity
ELECTRICITY FROM PROCESS HEAT
Due to the composition of the process gas and the process temperature, we use an externally fired micro gas turbine process (EFGT) as a basis. The process of the externally fired gas turbine is not to be equated with a conventional gas turbine process.
➀ The clean ambient air compressed in the compressor is passed through the heat exchanger and heated to the required turbine inlet temperature.
➁ After the hot air in the turbine has been expanded, it is used as process heat in the customer application. Whether the optional electrostatic precipitator is required depends on the flue gas composition of the heat source.
➂ After a heat sink, the EFGT can be connected and generate electricity from the waste heat.
Excursus on the subject of heat exchangers
The heat exchanger is not only characterized by its high temperature resistance, but also by its resistance to the chemical effects of the combustion gas. The flow-optimized design can be scaled to different performance classes.
Excursus on the topic of micro gas turbines
The micro gas turbine is the heart of the CHP system . The drive unit of the micro gas turbine is called a powerhead. The powerhead consists of the turbo group, which consists of the compressor wheel, turbine wheel and connecting shaft. The turbo group is air-bearing so that no lubricants or coolants are required. The powerhead including the turbo group is the central element of the micro gas turbine. Other components of the micro gas turbine are the generator, power electronics and control.
Which customer groups benefit from an EFGT system?
With two target groups, the profit margin can be increased with the added value::
What is the unique selling proposition of an EFGT?
The unique selling proposition of EFGT: Your fuel flexibility and decentralization. With a power range between 60 – 200 kW electrical, the EFGT is unique.
