Description

BURNER OPERATION
Field of the Invention
This invention relates to burners and is concerned with the provision of an environmentally friendly method of operating a burner.
It is an object of the present invention to provide a method of operating a burner that is such that the burner system can be operated independently and fitted anywhere in a house or other dwelling. A further object of the present invention is to provide a method of operating a burner which is such that the burner can be used with a chimney or flue but does not require the provision of a chimney or flue.
A further object of the present invention is to provide an improved burner operating system.
Summary of the Invention According to a first aspect of the present invention there is provided a method of operating a burner which comprises: a) providing a fuel supply reservoir, b) placing a fuel containing an alcohol in the fuel supply reservoir, c) connecting the fuel supply reservoir to a control chamber so that the fuel can flow from the reservoir to the control chamber, d) connecting the control chamber to the burner so that the fuel can flow from the control chamber to the burner, and e) providing a float valve within the control chamber for controlling the flow of the fuel from the reservoir into the control chamber.
The arrangement will thus be such that the level of the fuel in the control chamber will be maintained at a substantially constant level and the level of the fuel in the burner will not exceed a substantially constant level.
The fuel is preferably bioethanol, but other fuels containing an alcohol can be used in place of or in admixture with bioethanol. The fuel may contain any proportion of alcohol and the alcohol may be, for example, ethyl alcohol obtained by the fermentation of an agricultural product and, therefore, obtained from a renewable energy source. The alcohol may, alternatively, be methyl alcohol.
According to a second aspect of the present invention there is provided a burner operating system comprising a fuel supply reservoir in which, in use, a fuel containing an alcohol is placed, a control chamber connected to the fuel supply reservoir so that, in use, the fuel can flow from the reservoir to the control chamber, a float valve within the control chamber for controlling the flow of the fuel into the control chamber, and a burner having a combustion chamber connected to the control chamber so that, in use, the fuel can flow from the control chamber into the combustion chamber.
As explained above, the level of the fuel in the control chamber will be maintained at a substantially constant level and the level of the fuel in the burner combustion chamber will not exceed a substantially constant level.
The walls of the burner combustion chamber are preferably formed with a plurality of apertures for the flow of air into the combustion chamber, the apertures being so positioned thaVthey are above the maximum level of the fuel in the burner combustion chamber.
Brief Description of the Drawings
Figure 1 is a schematic view of a burner and its fuel supply system,
Figure 2 is a partly sectioned view of a control chamber, and
Figures 3 and 4 show the inlet valve of the control chamber in its open and closed positions respectively. Description of the Preferred Embodiment
The system shown in Figure 1 comprises a fuel supply reservoir in the form of a tank 10 connected by a line 11 to a control chamber 12 which, in turn, is connected by a line 13 to a burner 14. The fuel within the tank 10 is bioethanol though, if desired, other fuels containing an alcohol can be used in place of, or in admixture with, bioethanol.
The control chamber 12 contains a float 15 and the arrangement is such that, when the level of fuel within the chamber 12 is below that indicated in Figure 1 , the float 15 will be in a position corresponding to that shown in Figure 3 whereas, when the level of fuel within the chamber 12 reaches or exceeds that shown in Figure 1 , the float 15 will be in a position corresponding to that shown in Figure 4.
When the float 15 is in the position shown in Figure 3, an inlet valve 16 will be open (as shown in Figure 3) whereas, when the float 15 is in the position shown in Figure 4, the inlet valve 16 will be closed (as shown in Figure 4). As can be seen from the drawings, the float 15 is connected to a plunger 20 that forms part of the inlet valve mechanism. Movement of the plunger 20 from the position shown in Figure 3 into the position shown in Figure 4 serves to reduce the rate of flow of fuel from a maximum value to a minimum or zero value. The fuel within the control chamber 12 will thus be maintained at a substantially constant level, i.e. that shown in Figure 1.
As the control chamber 12 is connected by the line 13 to the burner 14, maintaining the fuel within the control chamber 12 at a substantially constant level will also maintain the fuel within the burner 14 at a substantially constant level, i.e. that shown in Figure 1. A control lever (not shown) may be provided for controlling the rate at which the fuel is supplied to the burner 14. The burner 14 comprises a burner chamber the top of which is substantially open to allow for the entry of air into the burner 14 and for the escape of the combustion products. In addition, the walls of the burner chamber are formed with a plurality of apertures 17 for the flow of air into the burner chamber. The apertures 17 are positioned just above the maximum level of the fuel in the burner chamber so that additional combustion air can enter the burner chamber without there being any possibility of the fuel escaping from the burner chamber. The flow of the air through the apertures 17, in addition to that entering the burner chamber through the open top thereof will improve the efficiency of the combustion reaction that takes place within the burner chamber.
There are other burners currently on the market that restrict the flow of air into the burner, but such arrangements have the disadvantage that they can result in the production of unwanted combustion products. An important advantage of the use of bioethanol as the fuel is that it comes from a renewable source and is biodegradable. A further advantage is that it is low in toxicity and causes little environmental pollution if spilt. It burns to produce carbon dioxide and water with ultra low production of carbon monoxide. Extremely efficient combustion is thus obtained without a requirement for a catalyst or expensive maintenance procedures. There is no smell produced on combustion and no soot formation.
The burner can be arranged to operate totally independently without connections to gas or electricity supplies. It is controllable in a manner similar to a normal gas stove and, though it does not require a chimney, it can be used with or without a chimney. It thus provides increased installation possibilities and is suitable for use in multi-storey dwellings. The burner is simple and economical to produce and reliable in operation.
