| | 0 | At about 14 : 00 on October 19, 2015, when operators polished the pipe orifice at the DN600 short joint of circulating water near the primary cooler of coking plant 2#, the splash prevention measures were not standardized. The sparks fell on the insulation cotton attached with tar, industrial naphthalene, and other carbon compounds, resulting in smoke and fire. After the fire was founded, the construction personnel and operators quickly used fire extinguishers to put the open fire on-site and reported to relevant leaders in time. | Coking plant, primary cooler, circulating water, polish, fire prevention measures, nonstandard, mars, tar, industrial naphthalene, carbonaceous compound, insulation cotton, smoke, catch fire, and fire extinguisher | | 1 | At 22 : 39 on February 19, 2016, 4# boiler an induced draft fan tripped, the DCS panel reported the failure of the thin oil station, and the lubricating oil pressure dropped to 0. Through inspection by site personnel, it was found that the upper end of the electric heating contactor of the induced draft fan was heated and burned out, its power air switch tripped, and the power switch of the control cabinet of the thin oil station tripped. At 23 : 16, after cutting off the electric heating power supply and turning on the control cabinet's power switch, the induced draft fan of party a usually starts, and the 4# boiler restores the load. | Induced draft fan, trip, thin oil station, fault, lubricating oil, pressure, decline, electric heating contactor, heating, burn out, power switch, control cabinet, and load | | 2 | At 6 : 15 on August 30, 2017, 5# boiler working condition was abnormal, and the deviation between main steam flow and feedwater flow was 100 t/h. After inspecting and confirming economizer leakage, it was reported to the general dispatcher to apply for boiler shutdown. After boiler shutdown, the 72nd and 76th low temperature economizers from east to west were leaked, and the leaking pipes were intercepted and discharged. | Working condition, abnormal, steam, flow, deviation, economizer, leakage, shutdown, low temperature, pipeline | | 3 | At 22 : 38 on July 29, 2018, the membrane recovery compressor PDT-3514 gave a low-pressure alarm, and the low alarm value was 135kpa. The oil pump G-370 A/B double pumps started, and the pressure of membrane recovery compressor C-351 did not return to normal, so it was immediately interlocked and shut down. | Membrane recovery, compressor, low voltage alarm, oil pump, interlocking, and shutdown | | 4 | At 16 : 40 on February 28, 2017, pulverized coal flow in the 1# pulverized coal pipeline of 1# gasifier suddenly dropped to 0. The gasification workshop analyzed and judged that there were sundries in the angle valve. After reporting to the plant leaders, it decided to dismantle and inspect the 1# pulverized coal angle valve, and some bag fragments were found in the angle valve. | Gasifier, pulverized coal, pipeline, flow, reduce, central control, main operation, angle valve, shutdown, fragment, and purge | | 5 | At about 23 : 20 on June 16, 2016, Xu, the first shift operator of the gasification workshop of the methanol plant, collided with an electric vehicle travelling in the opposite direction about 300 meters in front of the gate of the chemical base on his way to work, resulting in the rupture of Xu's left eyeball. He is now sent to the branch of the hospital for treatment. | Methanol plant, gasification workshop, operator, reverse driving, electric vehicle, collide, and fracture | | … | … | … |
