摘要:
设计一款以丙烷为燃料,适用于燃气干衣机的半预混旋流燃烧器.采用实验测量与数值模拟的方法,研究不同燃气流量和挡环高度对其CO排放的影响.研究表明:在工况中,燃气流量增加使一次空气系数下降,CO生成速率上升,故增加燃气流量后CO浓度升高;挡环主要影响燃烧器头部周围二次空气流场和火焰温度场,增加挡环高度后燃气空气混合程度上升,烟气温度升高;当燃气流量为0.207 m3·h-1,挡环高度分别为3,11,16 mm时,CO的实测体积比折算值分别为319,242,199 cm3·m-3,因此,增加挡环高度后CO减排效果明显.模拟结果显示:当燃烧器挡环高度为20 mm时,CO的排放量最低.
Abstract:
A semi-premixed vortex burner for gas dryer was designed with propane as fuel. The effects of power and retaining ring height on carbon monoxide emission were studied by methods of experimental measurement and numerical simulation. The research shows that with the increase of gas flow rate, the primary air coefficient decreases and the rate of CO formation increases, so the CO concentration increases with the increase of gas flow rate. The retaining ring mainly affects the secondary air and temperature around the burner head. With the increase of the height of the retaining ring, the gas-air mixing degree and the temperature increase. When the height of retaining ring is 3, 11, and 16 mm respectively, under the condition of 0.207 m3·h-1 burner gas flow rate, the measured CO concentration are 319, 242, and 199 cm3·m-3 accordingly. So, the effect of CO emission reduction is obvious when the height of retaining ring is increased. The simulation results show that when the height of burner retaining ring is 20 mm, the CO concentration is the lowest.
