(1) send out accident signal, sound and light alarm;
(2) interlock tripping mill, coal feeder;
(3) the negative pressure of the coal mill population decreases, and even the outlet temperature of the coal mill increases;
(4) Boiler load, steam pressure, steam temperature drop, combustion fluctuations in the furnace.
2. Reasons for failure of biomass heat conduction oil furnace
Power failure, accident button action or protection action;
(2)All induced draft fans or air ventilators tripping joint jump-row powder machine.
(1) adjust the negative pressure in the furnace, reset the trip switch,
(2) Tripping the pulverizing system back air, that is, close the coal machine population hot air door, the pulverizing machine population air door, open the cold air door.
(3) to find out the reason and deal with the rear can be restarted, restarted when the pulverizing system must be ventilated.
(4) if the operation can not be resumed in the short term, it should close the coal mill entrance damper and the outlet damper of the exhaust machine, open three times the wind cooling air, during the stop period, should pay close attention to the pulverizer system degrees, when necessary into the emotional gas protection, such as spontaneous combustion should be put into the fire fighting.
(5)When the pulverizing system is started after the accident trip, it should be carried out slowly in the ventilation and warm grinding to exhaust the powder in the system.
(6)For the low gas powder feeding and combustion system, the discharge machine should automatically jump the corresponding feeder after tripping, such as not jump, should manually stop the operation of the feeder, reduce the boiler load, stable combustion.
After the recovery of a wind should be a air duct ventilation purge, to prevent pipe plugging.
