摘要： A wood pellet stove for efficiently burning wood pellets and especially burning pellets at low burns. The stove is accurately controlled by a control panel with a microprocessor which helps safely regulate air flow from a combustion air and exhaust gas fan. Also, the microprocessor helps control convection air flow from a convection air fan and regulate feed of wood pellets into a burn pot using a motorized auger. The microprocessor is further used to monitor inlet air temperature and exhaust gas temperature. The stove includes a stove housing with a fire box and a fire box access door in the front of the housing. The burn pot includes a burn grate and pit used for receiving and burning wood pellets. The burn pot is disposed on a fire box floor. A wood pellet hopper is disposed in the rear of the housing for holding wood pellets therein. The motorized auger is used for feeding the wood pellets into the burn pot. The stove is characterized by having heat exchanger panels with dimpled surfaces which can easily be removed for cleaning. The dimpled panels are attached to the fire box walls with a space therebetween for forming air and exhaust gas channels. Combustion air and exhaust gases are circulated from the fire box, using an exhaust fan, up a front side of the panels and into the air and exhaust gas channels behind the panels for effectively extracting generated heat from the air and exhaust gases.

摘要翻译： 用于高效燃烧木材颗粒的木质颗粒炉，特别是在低烧伤时燃烧颗粒。 炉子由具有微处理器的控制面板精确控制，该微处理器有助于安全地调节来自燃烧空气和废气风扇的空气流。 此外，微处理器有助于控制来自对流空气风扇的对流空气流，并使用电动螺旋钻调节木颗粒进入燃烧罐的进料。 微处理器还用于监测进气温度和排气温度。 灶具包括一个带有防火箱的炉灶和一个位于屋顶前面的防火箱检修门。 燃烧锅包括用于接收和燃烧木颗粒的燃烧炉排和坑。 燃烧锅放在火箱底部。 木质小料斗设置在壳体的后部，用于在其中保持木颗粒。 电动螺旋钻用于将木颗粒喂入燃烧锅。 炉子的特征在于具有带有凹坑表面的热交换器面板，其可以容易地被移除以进行清洁。 凹陷板被附接到消防箱壁上，其间具有用于形成空气和废气通道的空间。 燃烧空气和废气从消防箱循环，使用排风扇，将面板的前侧向上延伸到面板后面的空气和废气通道中，以有效地从空气和废气中提取产生的热量。

摘要： A solid fuel heating apparatus has combustion air supplied in a controlled manner by a manifold. The manifold has a first branch that directs combustion air to the interior of the fuel ignited within the firebox and a second branch that extends along the forward edge of a baffle that extends from the rear wall of the firebox across a flue. Air issuing from the second branch is directed towards the fuel within the firebox so that a bodily rotation of gases within the firebox is obtained. A third branch extending generally parallel to the second branch is also provided and directs air towards the first branch. The air delivered by the second and third branch is roughly twice that delivered by the first branch and it has been found that this provides complete combustion of the fuel within the stove.
