自身预热烧咀的型式图1所示为自身预热烧咀原理图。这种燃烧装置是由一个燃烧通道,一个点火电极,一个带有防止温度升高保护套的煤气引入管,以及一个与烧咀连为一体的环缝式热交换器所组成。在环缝式热交换器中,外层流动的废气加热内层中与之逆向流动的空气。废气由引射器从炉内抽出。燃烧所需空气由风机鼓入。自身预热烧咀热交换器的高温部分置于炉墙之内,这种形式可以将散热损失降到最低程度。
Preheat itself burning Tsui type Figure 1 shows its own preheating Tsui schematic. The combustion unit consists of a combustion channel, an ignition electrode, a gas inlet with a protective sleeve against temperature rise, and a ring-fin heat exchanger integral with the burner. In a ring-and-ring heat exchanger, the exhaust gas flowing from the outer layer heats the air flowing reversely in the inner layer. The exhaust gas is drawn from the furnace by the ejector. The air needed for combustion is blown in by the fan. Preheat itself Tsui Tsui heat exchanger part of the high temperature placed inside the furnace wall, this form can be heat loss to a minimum.
