Abstract

  The radiant burner comprises a body defining a premixing chamber and a combustion chamber. The premixing chamber is separated from the combustion chamber by at least one radiant burner plate (2) having a plurality of stages of burner surfaces. The combustion chamber is further delimited by a first radiating screen. The radiant burner further comprises a second radiant screen (3) in the combustion chamber. The second radiant screen is arranged in the vicinity of and parallel to the radiant burner plate so that it functions as an extended burner surface in use and the at least one radiant burner plate is heated.

Description

  The present invention relates to a radiant burner comprising a radiant burner plate and a screen.

A radiant burner comprising a radiant burner plate and a screen is known, for example, from US Pat. No. 4,799,879 or EP 0539279. The screen cooperates with the radiant burner plate to provide the radiant output of the burner, which averages an efficiency level of about 50%. From a conventional radiant burner plate with a row of through holes or perforations that serve to direct a mixture of air and combustion agent from the back of the plate to the radiating surface, through holes or perforations are disclosed, for example, in US Pat. No. 4,569,657. As described in US Pat. No. 4,799,879, improvements have been made to modern radiant burner plates arranged in a so-called honeycomb pattern, which has increased the radiant power of the burner. This or a similar improvement of the radiant burner plate increased the temperature level and improved the radiant output of the burner.
On the other hand, these honeycomb-like patterns cause local overheating of the burner plate in the presence of the flame, impairing temperature uniformity, relatively lowering the average burner surface temperature, and improving energy efficiency. It is decreasing. Thus, such local high temperatures limit the use of through-holes or perforation patterns and also determine the upper limit on the amount of radiant energy that can be obtained in the system.

  Another way of achieving higher radiant power is proposed, for example in US Pat. No. 3,847,536, where two radiant screens are used above the radiant burner plate. However, this radiant burner improvement also causes local overheating of the radiant burner plate in the center of the radiant burner, so one skilled in the art can reduce the (local) temperature of the radiant burner plate to extend the life of the radiant burner In order to do this, we are forced to reduce input.

  However, further improvements in the efficiency of radiant burners are desired.

One aspect of the present invention provides a radiant burner with a body defining a premixing chamber and a combustion chamber. The premixing chamber is delimited from the combustion chamber by at least one radiant burner plate having a plurality of stages of burner surfaces, the range of the combustion chamber being further defined by a first radiating screen, and a second radiating chamber within the combustion chamber. A screen is further provided. The second radiant screen functions as an extended burner surface in use and is disposed in proximity to and parallel to the at least one radiant burner plate so that the at least one radiant burner plate is heated. .
In a preferred embodiment, the second radiating screen consists of a plurality of round bars or square bars arranged in parallel and spaced apart. In a preferred embodiment, the first and second radiating screens are high heat resistant materials such as ceramic, in particular aluminum oxide or zirconium oxide, aluminum titanate, silicon oxide, corundum or mullite, silicon carbide, silicon nitride or silicon. Manufactured from a metal infiltrated ceramic such as silicon-infiltrated silicon carbide. Alternatively, the radiant screen can be made from a refractory material of other properties, such as a material containing 50 wt% or more of a metal silicide, such as molybdenum disilicide (MoSi 2 ) or tungsten disilicide (WSi 2 ). In another preferred embodiment, the radiant screen is made of a high-grade stainless steel such as Kanthal APM or APMT, a high temperature corrosion resistant Fe-Cr-Al alloy, or Avesta 253MA, Avesta 153MA, Inconel 601, Incoloy 800HT, Manufactured from high heat resistant steel grades such as chromium / nickel steel such as Incoloy MA956.

  Radiant burner plates are preferably resistant to high temperatures and excellent mechanical and thermodynamic properties such as, for example, cordierite or zirconia, partially stabilized zirconia (PSZ), alumina, silicon carbide, or other high-grade industrial ceramics. Made of ceramic material. The height difference between the two burner surfaces of the radiant burner plate is 1 to 20 mm, more preferably 1 to 10 mm, still more preferably 2 to 7 mm, and most preferably 5 mm.

  The radiant burner plate has a plurality of stages of burner surfaces. In a preferred embodiment, these stages are arranged in rows and are arranged alternately for each row of through-holes / perforations in the radiant burner plate. An example of such a burner plate can be seen in FIG. 1 and alternative examples can be seen in FIGS. These types of burner plates have a low emissivity compared to ceramic tiles having a honeycomb or similar perforation pattern. This is because among the multiple burner surfaces of the radiant burner plate, the lower burner surface also heats the sides of the row to provide additional radiant power, resulting in higher radiant power. In contrast, the highest burner surface does not provide such additional radiant power, so the overall radiant power and energy efficiency in the multistage radiant burner plate itself is lower than the radiant burner plate with honeycomb perforations. .

Surprisingly, however, even though the radiant burner plate itself used has a low radiant power, placing a second radiant screen close to the radiant burner plate causes premature failure of the radiant burner plate. It has been observed that the radiant power of the radiant burner plate can be improved without causing local overheating of the burner plate. This is due to the fact that the back radiation of the second radiant screen relative to the multi-stage radiant burner plate is highest at the highest level of the burner surface, because it is closest to the second radiant screen, without any false accuracy. May be explained.
Thus, this highest stage heats more than the lower stage of the burner surface, which is a greater distance from this second radiating screen, but these lower stages of the burner surface of the radiant burner plate are the cavities where the perforations open. Due to the effect of the flame that heats the surface around the surface, it is already at a higher temperature, so that the overall effect of the present invention is to use different stages on the burner surface of the radiant burner plate at the same temperature in use. In other words, an improvement in temperature uniformity of the burner surface of the radiant burner plate is achieved. One skilled in the art will appreciate that improved temperature uniformity across multiple radiant screens results in improved energy efficiency for the overall radiant burner.
In a preferred embodiment, the distance between the second radiant screen and the highest step of the burner surface of the at least one radiant burner plate is 3-50 mm. More preferably, the distance between the second radiant screen and the highest step of the radiant burner plate is 5-30 mm, even more preferably 10-25 mm, most preferably 15-20 mm. In a preferred embodiment, the second radiant screen is arranged so that it follows the direction of the highest row of rows on the burner surface of the radiant burner plate.

  The first radiating screen is preferably a metal grid. In another preferred embodiment, the first radiating screen consists of a plurality of round or square bars arranged in parallel and spaced apart. More preferably, the first and second radiating screens are composed of a plurality of round bars or square bars arranged in parallel with each other. In a further preferred embodiment, the first and second radiating screens are arranged in the same direction. In a preferred alternative embodiment, the first and second radiating screens are arranged at an angle offset from each other. More preferably, the first and second radiating screens are at an angle of 90 °.

  A further advantage observed for the present invention is the low emission of combustion by-products such as nitrogen oxides or carbon monoxide. This appears to be due to the second radiant screen functioning as an enlargement of the burner surface, resulting in a more complete combustion of the gas-air mixture.

  Another aspect of the invention provides a radiant burner having at least one additional radiant screen in the combustion chamber.

  Exemplary embodiments of the present invention are described below with reference to the accompanying drawings.
