一、实验目的由日本引进的重油雾化器是一种高压内混式雾化器,油嘴可沿轴线方向在雾化剂通道中前后移动,其移动范围为2～8扣,当油嘴前移至第8扣时,雾化剂通道断面趋于最小。由于是内混式雾化器,高压气体雾化介质在雾化器内部即和重油相遇,且因油嘴位置可前后移动,因此这种雾化器的出力(小时喷油量)、蒸汽流量和单位燃料的汽耗率,不仅与油汽自身的初始压力有关,而且还和 First, the purpose of the experiment Introduced by Japan, heavy oil atomizer is a high-pressure mixed atomizer, the nozzle along the axis of the atomizer channel before and after the move, the movement range of 2 to 8 buckle, when the nozzle forward To the eighth buckle, the atomizer channel section tends to be the smallest. Because it is within the mixed atomizer, high pressure gas atomization medium in the atomizer that is, and heavy oil meet, and the nozzle position can be moved back and forth, so this atomizer output (hour fuel injection), steam flow and The rate of fuel consumption per unit of fuel is not only related to the initial pressure of the oil and gas, but also to the sum of the fuel consumption
