Cogeneration units

Electricity and heat from one system

We make energy-efficient cogeneration units in cooperation with the leading German manufacturer for CHP 2G. A cogeneration unit is the ideal solution for all those who want to reduce long-term energy costs and disconnect themselves from further rises in the electricity price. CHPs are becoming increasingly popular especially in the field of commercial and industrial buildings. CHPs will also become extremely important in general applications in future. It is estimated that by 2025, over 20% of the generated energy will be generated by CHPs and other cogeneration systems.

CHP units can be used very flexibly and make sense in any building where electricity and heat are required. Especially with regard to their energy requirements, commercial and industrial hall buildings provide a special challenge. CHP plants meet these challenges in a special way, which qualifies them for use in such buildings.

Schwank has been an expert in heating and cooling such buildings for over 80 years. We combine our experience in handling large hall constructions with 2G's motor expertise in CHP.

How does a CHP work?

The functioning principle of a CHP is really simple. A CHP is a gas-fired engine, which is connected to a generator as well as an exhaust gas heat exchanger. The gas motor drives the generator. This is how electricity is generated. The resultant exhaust gases are channelled through the heat exchanger. The heat can therefore be used sensibly. Thanks to the efficient use of the waste heat, a CHP can convert 95% of the used energy into heat and electricity. What’s more: the bigger the CHP [electrical output], the higher the overall efficiency.Possible areas of application of the generated heat:
  • Heating systems
  • Process heat
  • Steam generation
  • Hot water
  • Hot air
  • Thermal oils

For whom is a CHP beneficial?

A CHP is beneficial in any building where electricity and heat are required. A target-oriented design and size selection can take place through the following two approaches:

Current-regulated

In order to design the sizing of the CHP, the electricity requirement of the property is taken as the basis. The essential advantage of this method is that the CHP therefore serves as a backup for an extremely flexible power supply. Buffer storage is used in order to ensure a stable heat supply.

Heat-regulated

The heat requirement of the property is the focus of this approach. Unlike the design of conventional heating systems, the basic requirement - and not the peak demand - is taken in to account. The generated electricity is either consumed or fed into the public electricity grid. By means of absorption refrigeration, even a cooling solution is possible

How economically do cogeneration units work?

Blockheizkraftwerke werden aus wirtschaftlichen Gründen angeschafft. Ihre tatsächliche Wirtschaftlichkeit hängt von mehrer Faktoren ab:Annual operating hours
  • Depending on the continuity with which a CHP is operated, the efficiency can increase or decrease. The more the amount of electricity and heat generated, the more is the efficiency of a CHP.
Value of the generated electricity
  • If the generated electricity is fed into the public electricity grid, the fuel used plays a role. If the electricity itself is consumed, it need not be purchased expensively.
Value of the generated heat
  • The value of the generated heat can be derived from the costs that would arise if a conventional heating system is used.
