    • The present specification discloses a gas fire incorporating a heat exchanger (1) for use in transferring heat from the gaseous products of combustion in the gas fire (9) to a path (15) through the fire (9) for convection air. In certain such gas fires the heat exchanger is of a complex and expensive construction.
      The present invention provides a gas fire (9) with a simple and inexpensive heat exchanger (1). A number of these heat exchangers (1) are provided, each being in the form of a hollow tubular element (1) made of a thermally conducting material. Each hollow tubular element (1) extends across a path (15) for convection air in the fire (9), and provides a passage therethrough for gaseous combustion products passing to a flue at the rear (19) of the fire (9). To aid heat transfer fins (5) can be provided on the outside of the hollow tubular element (1).
    • 本说明书公开了一种含有热交换器(1)的气体火焰,该热交换器用于将气体火焰(9)中的燃烧气体产物的热量通过用于对流空气的火焰(9)传递到路径(15)。 在某些这种气体火灾中,热交换器是复杂且昂贵的结构。 本发明提供一种具有简单廉价的热交换器(1)的气体灭火(9)。 提供了多个这样的热交换器(1),每个都是由导热材料制成的中空管状元件(1)的形式。 每个中空的管状元件(1)延伸穿过用于火焰(9)中的对流空气的路径(15),并且提供通过其中的通道,用于通过火(9)的后部(19)处的烟道的气体燃烧产物。 为了帮助传热翅片(5)可以设置在中空管状元件(1)的外侧上。
