Definitions

  • the present invention relates to a fuel and the use of this fuel, in particular the use in refuse incineration.
  • Combustion is one of the most important chemical processes which people use. In the course of time, different fuels have therefore been found or developed for the various applications of combustion processes and have been optimized in their properties for the specific applications.
  • combustion processes One of the main uses of combustion processes is heat generation, whether for industrial use, electricity generation or heating purposes.
  • a further important field of use of combustion processes is mobility, since at present the vast majority of all vehicles are driven with the aid of internal combustion engines.
  • combustion processes are also used for thermal utilization of wastes or for rendering poisonous substances harmless by means of incineration.
  • the present invention proposes a fuel according to Claims 1, 7 and 13 and uses of the fuel according to Claims 18, 19 and 20. Further advantageous configurations, details, aspects and features of the present invention are evident from the subclaims, the description and the attached drawing. In the latter:
  • Fig. 1 shows the variation of the relative flame length of a tert-butyl peroxybenzoate pool flame as a function of time.
  • a fuel which comprises a compound having the empirical formula C n H n+3 O n - S , n > 9.
  • the compound may have the empirical formula CnHi 4 O 3 ; in particular, the compound may be tert-butyl peroxybenzoate (TBPB) .
  • a fuel which comprises an organic peroxide.
  • the organic peroxide may be a peroxy ester, in particular tert- butyl peroxybenzoate (TBPB) .
  • Organic peroxides in particular peroxy esters and among these TBPB, are known as free radical initiators for the polymerization of various monomers.
  • a use of this class of substance as fuel or fuel additive is not known to the applicant.
  • a fuel which comprises a compound whose pool flame has a Froude number which is 50 times to 100 times greater than the Froude number of a pool flame of kerosene.
  • the Froude number may be 70 times to 80 times greater than the Froude number of kerosene.
  • tert- butyl peroxybenzoate has a Froude number in this range.
  • the pool fire is understood as meaning a generally turbulent diffusion flame whose liquid fuel is horizontally propagated.
  • pool fires are a type of frequently occurring harmful fires which may arise, for example, during storage, transport and processing of liquid fuels.
  • the Froude number characterizes the initial pulse of the flame, small Froude numbers tending to be typical for pool fires since the flow velocity results substantially from the uplift of the combustion. Overall, the chemical and physical principles of pool fires have been thoroughly investigated and will not be further stated here.
  • Fig. 1 shows the variation of the relative flame length of a pool flame of tert-butyl peroxybenzoate as a function of time.
  • the relative flame length is obtained as the ratio H/d of the flame length H to the diameter d of the fuel pool.
  • the flame length H is defined as the maximum visible length of the flame, i.e. in the wavelength range between 380 nm ⁇ ⁇ ⁇ 750 ran.
  • Typical- values for the relative flame length H/d of conventional fuels, such as, for example, liquefied natural gas (LNG) or kerosene, are in the range between 0.8 and 4.
  • LNG liquefied natural gas
  • kerosene are in the range between 0.8 and 4.
  • the relative flame length H/d for tert-butyl peroxybenzoate as a function of time can increase to 18.
  • the tert-butyl peroxybenzoate flame has a relative flame length up to 18 times the pool diameter.
  • the relative flame length of the tert-butyl peroxybenzoate pool flame also decreases to low values of H/d « 2.
  • This variation in the relative flame length is not unusual per se and is also observed for other fuels.
  • what is surprising about the fuels described here is firstly the large variation of the relative flame length in order of magnitude and secondly the regularity of this variation.
  • the fuel shows an approximately periodic pulsation of the relative flame length which, owing to its appearance in the diagram (cf . Fig.
  • Fr f is the Froude number of the pool flame of the fuel. Since the Froude number of the fuels described is 50 times to 100 times greater than that of kerosene, their pulsation frequency f is accordingly 7 times to 10 times lower than that of kerosene. Furthermore, the combustion rate of the fuels described here is typically 80 times to 120 times higher than that of kerosene.
  • the fuels described here have a natural pulsation behaviour. If the fuels described here are therefore used in combustion processes, the advantages of pulsating combustion processes can be achieved without having to provide additional means, such as, for example, pressure generators or complex injection apparatuses. This not only reduces the costs but also permits more compact designs of the combustion devices.
  • the fuels described here can be used in particular in the area of refuse incineration and in particular in special waste or toxic waste incineration.
  • the fuels described firstly provide the described natural pulsation of the combustion; secondly, they simultaneously serve as a powerful combustion accelerator owing to the active oxygen present in the molecule. In this way, the pollutant and tar content of the combustion products can be greatly reduced, and this can be done with a simultaneously simpler mode of operation of the plant, since additional means for generating the pulsation are not required. Moreover, this reduces the costs of corresponding plants.
  • the fuels described here can also be used as fuels in a liquid drive or in a hybrid drive for a rocket.
  • the thrust F is in which r& is the mass flow rate, V e is the outflow velocity, p 0 is the external pressure, p e is the pressure of the outflowing gas and A e is the area of the outlet opening.
  • the fuels described have a substantially higher burn rate than conventional fuels, such as, for example, kerosene. Thus, an enormous gain in thrust can be achieved.
  • the fuels which are described here and which exhibit the pulsating combustion behaviour described may also be present as a mixture with other fuels, in particular other liquid fuels.
  • the fuels exhibiting the pulsating combustion behaviour can be provided as a fuel additive with a proportion of 0.1% by weight to 80% by weight of the total weight of the fuel.
  • said fuels can be provided with a proportion of 0.1% by weight to 20% by weight of the total weight of the fuel.
  • the exact proportion in the fuel depends on the specific use, provided that combustion of the additive can reliably take place. Thus, in some cases, a small proportion may be sufficient to initiate the desired pulsating combustion behaviour in the total system, while in other cases a high proportion is required.
  • the fuel may consist completely of a fuel having pulsating burning behaviour.
