山东鲁南化肥厂使用六十年代,上海锅炉厂制造的SHDP—30—25/400链条锅炉2台,经过数十年的运行检修暴露一些缺陷,每年因风室积灰造成炉排、炉链、滚筒烧损,炉排爬山等事故而引起停炉检修数10次/年,影响了我厂系统生产,造成了较大的经济损失和不必要的检修费用。 (1)炉排故障分析现我厂运行的锅炉SHDP—30—25/400型锅炉炉排为鳞片式不漏煤炉排,炉排下单个风室为1800×870mm,而落灰门为900×300mm搬板。轴仍为直径20mm的圆钢,因炉排本身问题及操作人员的责任心问题(不按时搬灰)造成炉排下风室积灰、积煤、烧坏风室或搬灰板等设备元件。
Shandong Lunan Chemical Fertilizer Plant used sixties in the SHP-30-25 / 400 chain boiler manufactured by Shanghai Boiler Factory. After several decades of operation and maintenance, it exposed some defects, resulting in grate, stove chain , Roller burning, grate climbing and other accidents caused by downtime maintenance 10 times / year, affecting our plant production, resulting in greater economic losses and unnecessary maintenance costs. (1) grate failure analysis Now I run the plant boiler SHDP-30-25 / 400 boiler grate-type coal-fired grate furnace, grate under a single plenum 1800 × 870mm, ash door 900 × 300mm moving board. The shaft is still a round bar with a diameter of 20mm. Due to the problem of the grate itself and the responsibility of the operator (not moving the ash ashore on time), the device components such as fouling of the wind grate of the grate, accumulating coal, burning air chamber or moving the ash board are caused.
