    • A tubular burner has a body comprising a diffuser portion provided with openings for discharging a mixture of air and fuel fed to the body through a Venturi tube arranged inside the body. The body has a cross section shaped in such a way that a distance between an outer wall of the Venturi tube and an inner wall of the body, when measured in a radial direction of the Venturi tube, has a first value substantially constant over a first portion of a perimeter of the Venturi tube and a second value greater than the first value over a second portion of the perimeter. A chamber is defined in the second portion between the outer wall of the Venturi tube and the inner wall of the body. The mixture passes through the chamber before being discharged through the openings. The chamber is delimited at a bottom thereof by laminar flow generating means for generating a substantially laminar flow of the mixture.
    • 管式燃烧器具有主体,该主体包括扩散器部分,该扩散器部分设置有用于通过布置在主体内的文丘里管排出供给到身体的空气和燃料的混合物的开口。 主体具有成形的横截面,使得当在文丘里管的径向方向上测量时,文丘里管的外壁和本体的内壁之间的距离具有第一值,该第一值在第一 文氏管的周边的一部分,并且在周边的第二部分上大于第一值的第二值。 在文丘里管的外壁和主体的内壁之间的第二部分中限定了一个腔室。 混合物在通过开口排出之前通过室。 该室通过层流产生装置在其底部界定,用于产生混合物的基本层流。

    • In a method of combustion designed to achieve a further reduction in harmful emissions, especially of NOx and CO, which is viable at advantageously reduced noise levels and lower cost with any burner of a type comprising a slotted or pierced diffuser of thin sheet metal in receipt of fully or partly mixed gas and air supplies, typically in appliances comprising a heat exchanger such as the boilers of central heating systems, the essential steps are: a) supplying a uniform flow of fuel-air mixture to the slots; b) discharging the mixture from a pierced surface of substantially doughnut geometry comprising a slotted peripheral area (Ap) and an essentially solid central area (Ac) of prescribed proportions; c) bringing combustion to completion in a slender lamellar flame; d) regulating the rate of aeration to a value between 0.9 and 1.4, or e) to values less than 1.6; f) effecting a recycle of post-combustion gases.
