我厂热处理间的盐浴炉,以废油为燃料.原来使用如图1所示的喷油嘴,升温慢,温度低,燃烧也不完全,烟道冒浓烟. 现在我们对原喷油嘴进行了改进.改进后的喷油嘴结构见图2,主要由风管、喷嘴体、转向管接头及油管等组成.为促使废油雾化良好,在风管上钻了φ3的小孔7,在喷嘴体上钻四个φ2.0～2.5的小孔3,使部分空气由孔7进入风管与喷嘴体之间所形成的空气室,再通过孔3进入油道,促使废油乳化.另外,
I plant between the salt bath furnace heat treatment to waste oil as fuel. The original use of the nozzle as shown in Figure 1, slow heating, low temperature, the combustion is not complete, flue smoke. Now we are the original fuel injection Improved nozzle structure shown in Figure 2, mainly by the air duct, nozzle body, steering pipe joints and tubing and other components to promote good waste oil atomization, drilling in the air duct φ3 small holes 7, drilled in the nozzle body four φ2.0 ~ 2.5 holes 3, so that part of the air from the hole 7 into the air duct and nozzle body formed between the air chamber, and then through the hole 3 into the oil, prompting the waste oil In addition,
