Figure 4 diagrammatically shows a typical domestic layout of the paraffin fuel utilising system with the geyser as forming part of it being shown in partly cut-away side elevation
(5) DETAILED DESCRIPTION OF THE DRAWINGS
Referπng to figures 1 and 2 of the drawings, combustible fuel water heating equipment in the form of a paraffin geyser is generally indicated by reference numeral 10
The geyser 10 comprises water flow path defining means defined along a mantle 12 within which a flue 14 is formed extending between an bottom heated air inlet end 14 1 , as extending above a burner 16 and an air exhaust end 14 2 with the flue being fitted with a heat exchange configuration generally indicated by reference numeral 18 The heat exchange configuration 18 incorporates primary heat conducting means provided by a grid of heat conducting material in the form of a plurality of parallel bridge members as provided by a number of flat plates 20 bridging the flue 14 in adequately spaced relationship to enable the unimpeded flow of heated air along the flue 14, and a heated gas flow path 5 layout in the form of a helically extending formation 22 extending inward from the flue encompassing wall 24.
The plates 20 are fitted adequately towards the inlet end 14 1 of the flue 14 to cause their direct exposure to the flame of combustion from the burner 16 once the geyser 10 is in use 0 To promote the transfer of heat as conducted along the plates 20 to cold water as introduced to the mantle 12 via its cold water inlet 12.1 , as is more clearly shown in figure 2, the plates 20 are integrally secured to the flue wall 24 at their corresponding ends 20.1 in the vicinity of the the inlet 12 1 The opposite ends of the plates 20 are naturally secured to the opposite side of the wall 24. 5
The plates 20, the helically extending formation 22 and the wall 24 of the mantle 12 are of suitable heat conducting material to promote the transfer of heat from heating medium as rising along the flue 14 once the geyser 10 is in use.
C The mantle 12 is naturally fitted with a heated water outlet 12.2 from which heated water is withdrawn when required.
The burner 16 can be of any conventional type such as an ordinary paraffin type burner as, for example, used by a 'primus stove'.The burner 16 is supplied with fuel from a pressurised 5 supply source and is fitted with a conventional electrical igniting facility 26 The facility 26 is, however, optional and not a requirement for proper operation of the geyser 10.
As the possibility of flame extinction always exists while the geyser is in use. the fuel supply to the burner 16 is fitted with a fuel supply cut-off valve 28 that closes off the flow of fuel to ι the burner 16 once the flame becomes extinct. This is achieved by way of a heat detecting probe 30 extending into the flaming zone above the burner 16 that causes the closing of the valve 28, fitted along the fuel supply line 32 to the burner 16 once a pre-set drop of temperature is detected in the flaming zone The mantle 12 is mounted along an outer shell 34 (shown in broken lines in figure 1) and packed with lagging material to limit the undesirable loss of heat to the environment once the geyser 10 is in use. As shown in figure 2, the outer shell 34 can conveniently be formed to be fitted into the corner of a room.
Referring to figures 3 and 4 of the drawings a liquid fuel operable system in the form of a pressurisable paraffin burning system is generally indicated by reference numeral 40. The system 40 comprises a manually pressurisable and transportable fuel supply reservoir 42 fitted with a pressure relief valve 44 and at least one but preferably a number of liquid fuel burner operable pieces of equipment 46 connected via fuel supply tubing 48 to the reservoir 42 once the system 40 is operatively installed. The reservoir 42 is fitted with a number of fuel supply outlet connections (not shown in detail) to enable its direct connection to a number of pieces of equipment 46. The system 40 also includes a conventional fuel flowrate control valve (not shown) for each piece of equipment 46 to enable controlling the fuel supply to the equipment enabling the simultaneous use of a number of pieces of equipment 46
Referring particularly to figure 4 a typical domesic application of the system 40 comprises the reservoir 42 connected by the tubing 48 to a burner operable oven 50, a stove 52, as conventionally situated on a support 54, and a geyser 56 The geyser 56 can conveniently be of the construction described with reference to figures 1 and 2 The reservoir 42 as manually transportable is held by a holder 58 mounted to oe out of the way but enabling convenient removal for recharging
The size of the reservoir 42 is selected to be adequate to hold fuel for an extended length of time when the system 40 is used in a conventional fuel consuming fashion it is also of adequately strong construction to enable its pressurisation to an extent only requiring infrequent repressurisation As an example in a domestic use situation the reservoir 42 has an overall volume of about seven litres When filled it holds about four litres of paraffin leaving the balance as air space for pressurisation The normal extent of pressurisation is in the order of 50 bar It will be appreciated that any suitable equipment can form part of the system 40. It can thus include a paraffin fridge, a vaporiser, a power generator or whatever further equipment that are operable via one or more burners. Although the system 40 is described by running on paraffin it will be appreciated that any suitable liquid and even gaseous fuel can be used with the neccessary adaptation of the burners.
The invention also extends to a set comprising the manually pressurisable and transportable fuel supply reservoir 42 as fitted with its pressure relief valve 44 and at least one but preferably a number of liquid fuel burner operable pieces of equipment 46. The set can conveniently include desired tubing, tubing connectors and an appropriate number of conventional fuel flowrate controllers enabling the full installation of the system 40 from the set.
