    • A gas water heater includes a water tank, a combustion chamber, a burner, a heat exchanger tube at least partially within the water tank, and a fan. The burner receives fuel gas and primary air to create a primary air-fuel mixture for combustion in the combustion chamber with secondary air. The primary air-fuel mixture has a gas concentration above the upper explosive limit of the fuel gas. Secondary air is supplied to the combustion chamber through a secondary air conduit that is separate from the burner. The heat exchanger tube receives the products of combustion, transfers heat from the products of combustion to water in the tank, and exhausts of the products of combustion. Only air flows through the fan; no fuel-air mixture flows through the fan. The water heater utilizes partial premix combustion with low excess air ratio and low contaminant emission. The water heater utilizes a high power burner such that the water heater can supply hot water continuously during low flow rate draws and hot water stored in the tank supplements the hot water supply of the water heater during higher flow rate draws.
    • 燃气热水器包括水箱,燃烧室,燃烧器,至少部分在水箱内的热交换器管和风扇。 燃烧器接收燃料气体和一次空气以产生用于在具有二次空气的燃烧室中燃烧的一次空气 - 燃料混合物。 一次空气燃料混合物的气体浓度高于燃料气体的上限爆炸极限。 二次空气通过与燃烧器分离的二次空气管道供应到燃烧室。 热交换器管接收燃烧产物,将燃烧产物中的热量传递到水箱中的水,以及燃烧产物的排气。 只有空气流过风扇; 没有燃料 - 空气混合物流过风扇。 热水器采用部分预混燃烧,过低空气比和低污染物排放。 热水器采用大功率燃烧器,使得热水器能够在低流速抽吸期间连续供应热水,并且储存在罐中的热水在更高的流速抽吸期间补充热水器的热水供应。
