SAACKE Energy Efficiency

Power production through CHP
combined heat and power
Direct use of gas turbine flue gas for combustion –
with high efficiency

The idea of using excess heat from generating electricity for process
steam or hot water is not new. It could better be described as a
logical step, because the hot flue gases of a cogeneration unit or a
gas turbine contain great quantities of valuable energy.
In a traditional combined heat and power plant (CHP) the hot flue
gas is directed immediately through a heat exchanger or waste heat
boiler. In this solution just presented by SAACKE it supplies a
DDZG-GTM series burner instead. That way SAACKE not only opens
the path to new high-temperature process for CHP plants, but also
makes production more flexible and profitable overall. Because CHP
plants can achieve high efficiency, they are not only very economical,
by also environmentally friendly.

In the low and medium load range these plants have most commonly been impemented with cogeneration units, which are very
maintenance-intensive, however. SAACKE is therefore now offering
an alternative: an extremely low-maintenance combination of micro
gas turbines with proven SAACKE burners known as „Micro CHPs“.
A gas turbine generates from 50 to 1000 kW of electrical power,
with its flue gas used to supply a SAACKE DDZG-GTM burner, which
fires in the downstream heat generator. Depending on the design
and configuration of the heat generator, a CHP like that produces
heat, steam or hot water with conventional heat generators – and
also produces valuable electrical energy.
