This utility model publicizes one kind of energy - saving heating stove belonging to heating stove technology, especially involving in a type of hot water energy - efficient heating stove, which mainly composed by the furnace body, the firebox, and the trough for releasing ash. on the furnace body is equipped with the hot water exportation, the cooling water inlet, the chimney, and the mouth for releasing ash. in the furnace body is equipped with the heater pipe, the thermal baffle, the furnace grate and the air throttle. in front part of the furnace body is equipped with the firebox door and the air throttle for entering. in front part of the trough for releasing ash is equipped with door. this energy - saving heating stove overcomes the deficiencies of the existing technology to provide good burn, smoke - free and dustlessness, and not to stop up the chimney and not to produce gas, which extremely suits to the households heating in rural areas
本實用新型公開了一種節能採暖爐，屬于採暖爐技術領域，尤其涉及一種熱水型節能採暖爐，主要由爐體、燃燒室、泄灰槽構成，爐體上設有熱水出口、冷水進口、煙筒、泄灰口，爐體內設有加熱管、隔熱板、爐箅子、內風門，爐體前部設有燃燒室門和進風門，泄灰槽前部設有泄灰槽門，本節能採暖爐克服了現有技術的不足提供了一種燃燒好、無煙無塵，不堵煙筒又沒煤氣的環保型節能採暖爐，非常適合於農村家庭採暖使用。 -
A mathematical model of flows in the substrate was established using the equivalent continuum approach, and multi - dimensional numerical simulation of the steady flows in the catalytic converters was performed. simulation results show that the separation and vortex, which cause the pressure loss and the velocity non - uniformity at the front of the first substrate, are generated near the wall of the conical pipe. in addition, the larger the inlet cones angle the more the pressure loss and maldistribution in converters, however, when the angle enlarges enough the pressure loss would be decrease
結果顯示氣流在擴張圓錐管壁附近出現分離產生較強的擾動，造成局部流動損失和載體前氣流速度沿徑向分佈不均勻；入口擴張管結構對催化器的流動特性有很大影響，但並非擴張角越大，催化器流速武漢理工大學碩士學位論文分佈的不均勻性和壓力損失也增大，而是存在著一個最佳角度，但當擴張角增大到一定程度以後，擴張角對流速分佈和壓力損失的影響變小。
