Definitions
- the present invention relates to a fan housing for a fan for supplying a fuel/oxidizer mixture to a burner.
- the invention further relates to an insert for such a fan housing.
- the present invention also relates to a supply device for such a fan housing.
- the present invention also relates to a heating appliance comprising such a fan housing.
- the present invention also relates to a hot water appliance comprising such a fan housing.
- the present invention also relates to a combi- boiler comprising such a fan housing.
- the invention also relates to a method for
- thermo-acoustic behaviour is influenced not only by the burner itself but also by elements upstream and, to lesser extent, downstream of the burner.
- One of the elements affecting the thermal-acoustic behaviour is a fan which forces the fuel/air mixture through the burner.
- the object of the present invention is to provide a heating appliance with an improved thermo-acoustic
- the present invention provides for this purpose a fan housing for a fan for supplying a fuel/oxidizer mixture to a burner, comprising: a supply opening? a fluid supply space debouching at the supply opening a first supply means for supplying a fluid-like fuel; a second supply means for supplying an oxidizing fluid; wherein the fluid supply space comprises mixing means for mixing the fluid-like fuel with the oxidizing fluid; and wherein the supply opening lies at an angle relative to the supply direction of the fluid in the fluid supply space.
- the fuel comprises natural gas and the oxidizing fluid comprises air.
- the fuel comprises methane, propane and/or butane.
- thermo-acoustic behaviour of the burner is positively affected in the sense that the noise production decreases .
- thermo-acoustic behaviour compared to prior art heating appliances is provided by applying the fan housing in a heating appliance.
- a fan housing wherein the mixing means comprise a venturi. Due to the venturi an underpressure is created close to the venturi and downstream of the venturi, whereby the oxidizing fluid is drawn out of the second supply means and mixes with the fuel.
- the present invention provides a fan housing wherein the supply opening is disposed transversely of the supply direction of the fluid in the fluid supply space. Measurements by applicant have shown that the transverse placing of the supply opening has a particularly favourable effect on the thermo-acoustic behaviour of the burner.
- a fan housing wherein the second supply means is arranged in the first supply means and lies in the flow direction of the first supply means, and which second supply means debouches in the first supply means, and wherein the first supply means comprises a narrowing close to the mouth of the second supply means.
- the narrowing close to the mouth of the second supply means forms the venturi .
- the venturi is arranged on the second supply means, which is in turn arranged in the first supply means, and this assembly is formed integrally with the fan housing, a particularly compact construction is obtained.
- a heating appliance is hereby obtained which not only has a more favourable thermo- acoustic behaviour than in the prior art but is also more compact.
- thermo-acoustic behaviour of a heating appliance comprising such a fan housing.
- the obstruction makes a positive contribution toward the thermo- coustic behaviour.
- a circulating underpressure results at the position of the supply opening of the fan housing.
- the obstruction impedes the circulating fluid flow and causes a local pressure increase at the position of the mouth of the second supply means, whereby the gas supply stops. The result is a more favourable thermo-acoustic behaviour than is the case in the prior art .
- thermo-acoustic behaviour is irrespective of the fact that the supply opening of the fan housing lies at an angle relative to the supply direction of the fluid in the fluid supply space. Both the obstruction and the angle each have a favourable effect on the thermo- coustic behaviour and can be implemented independently of each other.
- the invention provides a fan housing wherein the protruding obstruction is an extension of the wall of the second supply means.
- the obstruction can in this way be formed in simple manner.
- the present invention provides a fan housing wherein the second supply means and the mixing means are formed from an insert which can be placed in the fluid supply space.
- the second supply means and the mixing means are formed from an insert which can be placed in the fluid supply space.
- the present invention also provides such an insert.
- the invention provides a. supply device for supplying fluid to a fan housing, comprising a closing part for closing a supply side of a fan housing; a fluid supply space for supplying a fluid, wherein the fluid supply space debouches on the fan side of the closing part by means of a supply opening; a first supply means for supplying fluid-like fuel; a second supply means for supplying an oxidizing fluid; wherein the fluid supply space comprises mixing means for mixing the fluid-like fuel with the oxidizing fluid; and wherein the supply opening lies at an angle relative to the supply direction of the fluid in the fluid supply space.
- the present invention provides an embodiment in which only a supply device is provided, which can be arranged on the supply side of a fan housing.
- the supply device is embodied as a cover of the fan housing.
- the present invention further provides a heating appliance comprising such a fan housing or a fan housing comprising such a supply device.
- the invention also provides a hot water appliance comprising such a fan housing or a fan housing comprising such a supply device.
- the present invention also provides a combi-boiler for heating tap water and central heating water, the combi-boiler comprising such a fan housing or a fan housing comprising such a supply device.
- a method for supplying a fluid-like fuel with an oxidizing fluid to a fan comprising the steps of: guiding the fluid- like fuel through a venturi; providing the oxidizing fluid in or close to the venturi, whereby the oxidizing fluid is drawn in by the venturi effect and mixes with the fluid-like fuel; supplying the mixture of the fuel and the oxidizing fluid at an angle to a fan, which fan blows the mixture into a burner space.

- FIG. 4 shows a second axonometric view of the supply device of figure 2.
- a fan housing 10 (figure 1) is provided with a supply device 20 according to the present invention.
- Supply device 20 is embodied as a cover arranged on the supply side of fan housing 10.
- Fan housing 10 comprises a main body 30 and a discharge conduit 42 for guiding a gas/air mixture to the burner.
- the natural gas is supplied via a supply conduit 28 , in which is placed the insert 50 comprising a venturi 54.
- Venturi 54 causes an underpressure downstream of the venturi in the natural gas supply conduit 28.
- air is drawn in from air supply conduit 52, whereby a mixing of the natural gas and the air occurs in fluid supply space 26, a part of the outer wall 24 of which is cut away in figure 1A.
