    • A radiant heater which burns LPG fuel is provided with an improved burner assembly and an improved support assembly for mounting the heater on a propane tank. The heater includes a frame, a reflector mounted on the frame, and a burner assembly which is removably mounted within the reflector and the frame. The burner assembly includes a burner tube having an inlet end mounted within the frame and an outlet end positioned within the reflector. A generally dome-shaped screen is mounted on the outlet end of the burner tube, and a generally circular screen is attached to the dome-shaped screen substantially in alignment with the burner tube. A burner pan is mounted on the burner tube and surrounds the dome-shaped screen, and an outer screen extends across the burner pan. A thermocouple sensor and/or an igniter electrode on the frame extends through one or more openings in the burner pan. A single fastener prevents removal of the burner assembly from the frame, and when the fastener is disengaged from the burner assembly, the burner assembly can be removed and replaced. The support assembly includes a rigid support member which extends downwardly from the frame and is releasably engageable with an LPG tank. In one embodiment the support member is a fuel conduit which is connectable to a fuel valve on the LPG tank. A support bracket is adjustably mounted on the fuel conduit and is engageable with the top of the LPG tank.
    • 燃烧LPG燃料的辐射加热器设置有改进的燃烧器组件和用于将加热器安装在丙烷罐上的改进的支撑组件。 加热器包括框架,安装在框架上的反射器以及可拆卸地安装在反射器和框架内的燃烧器组件。 燃烧器组件包括燃烧器管,其具有安装在框架内的入口端和位于反射器内的出口端。 大致圆顶形的屏幕安装在燃烧器管的出口端,并且大致圆形的屏幕附接到基本上与燃烧器管对准的圆顶形屏幕。 燃烧器盘安装在燃烧器管上并且围绕圆顶形状的屏幕,并且外部屏幕延伸穿过燃烧器盘。 框架上的热电偶传感器和/或点火器电极延伸穿过燃烧器盘中的一个或多个开口。 单个紧固件防止燃烧器组件从框架移除,并且当紧固件从燃烧器组件脱离时,可以移除和更换燃烧器组件。 支撑组件包括从框架向下延伸并且可释放地与LPG罐接合的刚性支撑构件。 在一个实施例中,支撑构件是可连接到LPG箱上的燃料阀的燃料管道。 支撑托架可调节地安装在燃料管道上并且可与液化石油气罐的顶部接合。
