Fuel Technology
The Division of Fuel Chemistry and Technology of the DVGW
-Forschungsstelle, is focused on technical processes and technologies for gas production, distribution and utilization. Gas
odorization is one main research topic over the last years.
The introduction of sulfur free odorization in Germany was
scientifically reviewed. Together with metrological investigations and olfactory analysis, topics like material compatibility
and physical and chemical interactions also were in the focus
of the studies.
Another important field of activity is the gas quality, with the
focus on the use of natural gas as fuel and the injection of
biogas. Current projects covering the injection of gaseous
fuels from renewable energy sources and on the resulting
requirements on the network infrastructure, measuring and
billing technology.
Sampling and analysis of fuels
• natural gas – sampling and analysis
• natural gas as fuel – sampling and analysis
• biogas, sewage gas, landfill gas – sampling and analysis
• liquefied natural gas – sampling and analysis
• industrial process gas – sampling and analysis
• checking measurements of odorants
• analysis of sulphur of gaseous, liquid and solid fuel
• calorific characteristics of gaseous, liquid and solid fuel
• development of sampling and analysis methods

Combustion technology
The Combustion Technology Department of the DVGW-Forschungsstelle, is focused on the scientific investigation of
industrial and domestic gas appliances. Particularly with
regard to innovative technologies like gas heat pumps and
micro CHP systems, the appliances are tested on several
test benches concerning performances and emissions. The
scientists also support the development of established gas
application technologies in cooperation with the gas appliance manufacturers. The ongoing projects focus on optimizing
fuel efficiency, reducing emissions and ensure high safety
standards. Hence the DVGW-Forschungsstelle makes an
important contribution to an energy-efficient, cost effective
and environment friendly gas utilization for industrial and
domestic users.
