    • In a combustion device, a boiler is provided with a water tube nest in which combustion, flame holding, fuel-air mixing, and heat absorption are carried out by each water tube in a tube nest. The arrangement of this combustion device enables elimination of the conventional burner and furnace. Fuel supply devices are provided upstream of the water tube nest to supply fuel or a fuel-air mixture. One or several combustion catalysts are provided across the gas flow direction in the boiler to promote combustion. In one arrangement, the fuel supply devices are fuel supply tubes, and fuel or fuel and air are supplied to the fuel supply tubes and spouted from fuel injection nozzles thereof. The fuel supply tubes and water tubes are arranged such that the row of fuel supply tubes is spaced upstream from the first water tube row, such that L.gtoreq.3D where L is the pitch between the fuel supply tube row and the first water tube row, and D is the diameter of the water tubes. Also, P.gtoreq.2D where P is a longitudinal pitch between the water tube rows. A suitable number of fins having a suitable angle and height can be provided on the water tubes and/or the fuel supply tubes. U-shaped or other openings can be made in the fins.
    • 在燃烧装置中,锅炉设置有水管座,其中管座中的每个水管执行燃烧,火焰保持,燃料 - 空气混合和吸热。 该燃烧装置的布置能够消除常规的燃烧器和炉子。 燃料供应装置设置在水管窝的上游,以供应燃料或燃料 - 空气混合物。 在锅炉中跨气体流动方向提供一种或多种燃烧催化剂以促进燃烧。 在一种布置中,燃料供给装置是燃料供给管,并且燃料或燃料和空气被供应到燃料供应管并从燃料喷射喷嘴喷出。 燃料供给管和水管被布置成使得一排燃料供应管与第一水管列的上游间隔开,使得L> / = 3D,其中L是燃料供应管排和第一水管之间的间距 行,D是水管的直径。 此外,P> / = 2D,其中P是水管列之间的纵向间距。 可以在水管和/或燃料供应管上设置合适数量的具有合适角度和高度的翅片。 U形或其他开口可以在翅片上制成。
