一九八三年十月十九日至二十一日江苏省冶金厅在苏州市召开了MFP型可调旋流煤粉烧咀鉴定会。MFP型可调旋流煤粉烧咀在结构上具有形成强旋流的装置,并设有内混式的收扩形可调节的钝体。该烧咀具有火焰燃烧长度及张角可调、铺展性好、点火容易,燃烧稳定等特点,受到试用单位的欢迎。这种烧咀在研制过程中进行了冷态、热态小型试验,又在生产现场进行了工业性试验。经苏州轧钢厂一年来试用证明:新型烧咀节能效果较好,燃料节约率为9.93%;燃烧较完全,灰分残炭率为4.46%,操作、维修比较简单。
From October 19 to January 19, 1983, Jiangsu Provincial Metallurgical Department held an appraisal session on the MFP type swirling pulverized coal burner in Suzhou. The MFP-type swirling pulverized coal burner has a structure that forms a strong swirling device and is provided with an internal mixed bluff body that can accommodate the expansion and contraction. The burned nozzle has the characteristics of flame burning length and adjustable opening angle, good spreadability, easy ignition and stable combustion, which are welcomed by the trial units. This burning Tsui in the development process carried out a cold, hot small test, but also in the production site for industrial testing. After a year of trial use of Suzhou rolling mill, it proved that the new type of burner has better energy saving effect and the fuel saving rate is 9.93%. The combustion is complete and the ash residue charring rate is 4.46%. The operation and maintenance are relatively simple.
