    • There is disclosed a gas-fired water heater/boiler apparatus with a unique burner assembly that provides high levels of BTU/hour input making it suitable for commercial installations. The gas burner includes a pair of superimposed tubes, each having evenly distributed perforations of a different uniform size, that are rolled flush together and provide a thick walled burner with greatly increased strength and resistance to premature failure while furnishing an optimum flame pattern. The gas burner projects into the interior of a vertical, cylindrical array of finned heat exhanger tubes through which the fluid to be heated is circulated. The water heater/boiler apparatus is compact and thermally insulated by a pressurized forehearth and may be installed on combustible floors or in closets with zero clearance.
    • 公开了一种具有独特燃烧器组件的燃气热水器/锅炉设备,其提供高水平的BTU /小时输入,使其适合商业安装。 气体燃烧器包括一对重叠的管,每个管具有均匀分布的不同尺寸的穿孔,其被平齐地卷成一体,并提供具有大大提高的强度和耐过早失效的厚壁燃烧器,同时提供最佳的火焰图案。 气体燃烧器投射到垂直的圆柱形翅片式热交换器管的内部,待加热的流体通过该排气管循环。 热水器/锅炉设备紧凑,通过加压前炉进行隔热,并可安装在可燃地板或零间隙的橱柜内。
