摘要： A damper and air flow control for use with fireplaces or stoves having a plurality of heat tubes extending through the exhaust passage for smoke and other products of combustion includes a plurality of slats secured in spaced side-by-side relation to one another. Each slat is adapted to be positioned above a heat tube when the damper is in open position so as to leave the spaces between the heat tubes substantially unobstructed. Each slat has a width greater than the space between the heat tube over which it is positioned when the damper is open and an adjacent heat tube so that the slats may be moved to a position where they substantially block the spaces between the heat tubes. Control apparatus is provided to move the slats between open, closed, or partially closed positions.
摘要翻译： 用于壁炉或灶具的阻尼器和空气流量控制器具有延伸穿过用于烟雾和其它燃烧产物的排气通道的多个热管，包括彼此并排固定的多个板条。 当阻尼器处于打开位置时，每个板条适于定位在热管上方，以便使热管之间的空间基本上不受阻碍。 每个板条的宽度大于当阻尼器打开时其被定位的热管之间的空间和相邻的热管，使得板条可以移动到它们基本上阻挡热管之间的空间的位置。 提供控制装置以在打开，关闭或部分关闭位置之间移动板条。

摘要： An enclosed gas fireplace which efficiently transfers heat from a combustion chamber to surrounding air chambers and to air flow conduits which pass through a flue gas offtake. The fireplace has an outer shell that remains relatively cool, so that the fireplace can be installed in a framed sheetrock or wood enclosure without the need for utilizing the special masonry work or masonry chimney normally required for a fireplace. In addition, the invention provides a special burner arrangement to enhance the aesthetic quality of the fire and which provides a clean-burning gas flame to meet modern emission standards.
摘要翻译： 封闭的燃气壁炉，其有效地将热量从燃烧室传递到周围的空气室，以及通过烟气排出的气流管道。 壁炉有一个外壳，保持相对凉爽，因此壁炉可以安装在框架的木板或木质外壳中，无需使用壁炉通常需要的特殊砖石工或砖石砌筑烟囱。 此外，本发明提供了一种特殊的燃烧器装置，以增强火焰的美学质量，并提供清洁燃烧的气体火焰以满足现代排放标准。
