Ignition reactor

The ignition reactor is an electrically heated cylindrical oven in which investigations regarding to the ignition properties of fuels can be conducted. Temperature and gas atmosphere are adjusted in advance (e.g. O2, O2/N2, O2/CO2).          

Initially a sample of solid fuel is blown into the reactor, subsequently a dust cloud is formed which then ignites.

The time span up to ignition and the duration of combustion are measured by a computer controlled acquisition system.

Objectives

The influence of different parameters is investigated, e.g. type of fuel, furnace temperature, reactor atmosphere, particle size and inflow velocity. Furthermore additional information such as combustion kinetics, reaction rate, activation energy and frequency factor are derived. 

Projects

New production processes, quality strategies and optimization for the application of high-quality Refuse Derived Fuels (RDF)
