Combustion of peroxy-fuels
(2011)
The diffusion flames of organic peroxides exhibit quite different characteristics than hydrocarbons. What makes them interesting to study is their fast burning behaviour. As a result the flame temperature enhances and so does the thermal radiation. Due to all these they demand safe handling during processing. However, they can be utilised at several places in different industries where a fuel with fast burning, high temperature and intense radiation are desired. Some of the possibilities to use them as a main or supporting fuel in a wide range of industrial utilities are the major content of this paper.
The use of energetic materials as a main fuel in high temperature process
industries are not known to the scientific community as such. This paper
highlights some of the features and advantages of using organic peroxides
especially di-tert-butyl peroxide (DTBP) in high temperature process industries.
The feasibility of using DTBP as a main or supporting fuel in process industries
have also been justified with the help of Computational Fluid Dynamics (CFD)
simulations. For peroxides requirement of less fuel and air for the same amount
of heat flux has been shown. The resulted emission from the combustion of
DTBP is also discussed.
A new burner concept (PEROXY-BAM®) for the combustion of liquid organic peroxides (Peroxy-fuels) is presented. As peroxy-fuels are thermally unstable the design of burners for them should be accordingly modified ensuring a safe operation. It is found that 10 to 100 time less amounts of peroxy fuels are required for the same heat flux or output in comparison to hydrocarbons. Correspondingly, the fuel pump power and the volume of combustion chamber (furnace) are also reduced. As a result of less amount of fuel the emissions will also be stepped down and oxygen in the molecule helps to establish conditons like in an oxy-fuel combustion process. The advantages of using peroxy-fuels over hydrocarbons inside a model combustion chamber are also investigated with the help of CFD (Computational Fluid Dynamics) simulations.
