    Abstract: This disclosure teaches a direct fired heater with a double casing. The double casing includes a somewhat conventional inner casing having a burner penetrating therethrough and an outer casing spaced from the inner casing to form a passage in flow communication between the atmosphere and the burner. The outer casing surrounds the burner and is provided with an acoustic inner surface to minimize escape of noise. Design of refractory linings with respect to thickness and density allows for maintenance of skin temperature of the inner casing above the condensation ranges of SO.sub.2 and SO.sub.3.

    Abstract translation: 本公开教导了具有双壳体的直接燃烧加热器。 双壳体包括具有穿透其中的燃烧器的稍微传统的内壳体和与内壳体间隔开的外壳，以在大气和燃烧器之间形成流动连通的通道。 外壳围绕燃烧器并设置有声学内表面以最小化噪音的逃逸。 耐火衬层的设计相对于厚度和密度允许内部壳体的皮肤温度维持在SO2和SO3的冷凝范围之上。

    Abstract: A forced air heating system having a combustion chamber with an air inlet which leads exteriorly of the building heated. A furnace includes a combustion chamber with an outlet connected to a flue leading from the chamber to exteriorly of the building. The combustion chamber has an air inlet connected to an air inlet duct which leads exteriorly of the building to allow air flow into the chamber for combustion purposes. The furnace includes a heating passage adjacent to the combustion chamber which is connected to cold air ducts and hot air ducts. Means mounted in the heat passage is operable to force air from the cold air ducts through the heating passage to the hot air ducts. A valve means is provided in the air inlet duct leading to the combustion chamber for control of air through the air inlet duct.

    Abstract translation: 一种具有燃烧室的强制空气加热系统，该燃烧室具有引导室内外加热的空气入口。 炉子包括燃烧室，出口连接到从室到达建筑物外部的烟道。 燃烧室具有连接到空气入口管道的空气入口，该入口管道引导建筑物的外部，以允许空气流入室中用于燃烧目的。 该炉包括与燃烧室相邻的加热通道，其连接到冷风管道和热空气管道。 安装在热通道中的装置可操作以迫使来自冷空气管道的空气通过加热通道进入热空气管道。 在通向燃烧室的空气入口管道中设置有阀装置，用于通过进气管道控制空气。
