Definitions
- the present invention relates to a premix burner, more in particular a burner having a flameholder made of perforated metal plate material.
- the burner is a tubular burner having a cylindrical shape. These burners are especially suitable for use in combustion boilers.
- premix burner consist of one or more of the following components: a) an end cap located at the top of the burner, b) a burner deck, the burner deck consists of a blind piece at the bottom, a perforated piece, with a regular (circular) pattern, with sometimes locally an additional modification for ignition purposes, in the centre part and a blind piece at the top.
- the pattern is mostly circumferential, and mostly repeating itself in height after a pitch of 1-10 mm; c) a distributor, having a blind piece at the bottom, a perforated part in the centre and a blind piece at the top; d) a distributor end cap; e) a flange; f) an anti noise tube which is a device located in or nearby the flange to adjust the pressure distribution.
- a distributor having a blind piece at the bottom, a perforated part in the centre and a blind piece at the top
- d) a distributor end cap e) a flange; f) an anti noise tube which is a device located in or nearby the flange to adjust the pressure distribution.
- Such premix burners are described in e.g. EP 1337789 , EP2037175 , WO2009/077333 , WO2009/065733 , WO2009/059933 .
- these burners are provided with devices in the mixing chamber, such as e.g
- an inner liner also called distributor and/or anti-noise tube or other devices such as swirls or perforated disks in or nearby the flange.
- distributor and/or anti-noise tube or other devices such as swirls or perforated disks in or nearby the flange.
- the object of the present invention is to obviate the drawbacks mentioned above.
- An object of the present invention is to provide a premix burner which does not need such devices in the mixing chamber of the burner to obtain a good stability of the flames and to reduce or even eliminate noise problems.
- a further object of the present invention is to provide a premix burner with a good stability over the full operating range of high to low CO 2 , and for the full band of customary or natural gas qualities.
- This full band of customary and natural gas qualities covers all gases selected from hydrocarbons such as methane, ethane, propane, butane, ethene, propene, butene, acetylene, and the like.
- hydrocarbons such as methane, ethane, propane, butane, ethene, propene, butene, acetylene, and the like.
- the present invention does not relate specifically to high reactive fuel gases, which are a mixture of hydrogen and customary fuel gases.
- a further object of the present invention is to provide a premix burner producing low NOx levels.
- An aspect of the claimed invention provides a gas burner, preferably a premix burner, as in claim 1.
- the burner deck has an overall porosity which is equal to or lower than 11 %, preferably lower than 10%, even more preferably lower than 9%.
- the present invention provides a gas burner as described above wherein the burner further comprises an end cap connected to the perforated metal plate substantially opposite to said gas inlet port.
- the present invention provides a gas burner as described in paragraph 8, wherein the end cap is also provided with perforations. These perforations thereby enlarge and are part of the burner deck.
- the end cap is made of metal plate material.
- the perforation patterns in the end cap and in the perforated metal plate are equal.
- the perforation patterns in the end cap and in the perforated metal plate are different.
- the perforations, such as e.g. slots and holes, in the end cap and in the perforated metal plate are equal.
- the perforations in the end cap and in the perforated metal plate are different.
- the gas burner of the type described above has a burner deck wherein more than 50% of the burner deck has a porosity being equal to or lower than 9% and wherein upto 50% of the burner deck has a porosity being higher than 11 % and with an overall porosity which is equal to or lower than 11 %.
- This modification of the perforation pattern of the burner deck provided a burner which, next to the effect of the deletion of the diffuser and the removal of the humming noise, also had a more stable response on the second and higher Helmholtz or instable acoustic resonances of the heat exchanger, which therefore made that the boiler, with this build in burner did not provoke a whistling sound anymore.
- Another aspect of the claimed invention provides a gas burner as described in [0007], [0008], [0009] or [0011] wherein the burner deck has different patterns of perforations. Adding more patterns with different pitches showed an increased stability for a broader range of gas qualities and induced less NOx-emissions.
- the burner is provided with an abrupt and stepwise variation of the perforation pattern in the burner deck.
- the present invention provides a burner with gradually increasing or decreasing perforation pattern or gradually increasing or decreasing pitches in between the perforation pattern of the burner deck. This grading can go in axial or circumferential direction. Gradually increasing or decreasing the perforation of the decks allows an almost step less variety of the perforation, and thus creating a varying perforation of the surface of the deck.
- the part with a porosity higher than 11% is closest to the gas inlet.
- the part with a porosity equal to or lower than 9% is most remote, i.e. downstream, from the gas inlet.
- burner deck is to be understood, in the light of this invention, to be that part of the burner where the totality of perforations are present. In case two or more distinct regions of perforations can be detected on the burner surface, the burner deck is defined as being the surface spanning of all regions with perforations.
- all porosity of the burner deck is to be understood, in the light of this invention, as ratio of the surface of the holes, slots or other openings divided by the surface of the burner over which the perforated part(s) is(are) located.
- perforation pattern is to be understood, in the light of this invention, to be a recurring scheme of perforations.
- FIG. 1 shows a gas burner 10, preferably a premix burner, comprising a support or flange 12 which has a central gas inlet port 14 for supply of gas into a gas supply or mixing chamber 16.
- the gas supply chamber 16 is enclosed by a perforated metal plate 22.
- the perforated metal plate 22 is connected at the bottom to the support or flange 12 through a base section.
- the perforations 24 in the perforated metal plate 22 provide the burner deck 20.

- This pattern is repeated over the burner deck on the circumference of the burner. This provides a burner deck which has an overall porosity of 9,8%.
- This modification of the perforation pattern of the burner deck provided a burner which, next to the effect of the deletion of the diffuser and the removal of the humming noise, also had a more stable response on the second and higher Helmholtz or instable acoustic resonances of the heat exchanger, which therefore made that the burner did not provoke a whistling sound anymore.
- the humming sound was eliminated and therefore the use of anti-noise devices in the mixing chamber of the burner could be omitted.
- the use of the relatively high porosity at the beginning and end of the burner deck 20 provide an even more stable flame pattern of the burner.
- Figure 5 provides a gas burner with a perforated metal plate 22 with a perforation pattern.
