1 coke oven gas engine generator sets in the composition of the internal local power supply network, the total power distribution room low-voltage main switch installation synchronization device and a synchronization device and power through the low voltage grid available for internal use.
2 install a reverse power protection module at the low voltage main switch of the main distribution room, which can prevent the power generated by the generator from being sent back to the power grid when the external network is blackout.
3 when the external power failure, low voltage switch through the inverse power module control circuit breaker tripping into isolated operation of generator, ensure the main equipment of fan, circulating ammonia pump constant electric and normal operation can be avoided; because coke oven fan stop caused by fireworks pollution, such as power can also be large enough to ensure the normal production of the coke oven.
4, when the external network power supply again, through the main switch at the same time again connected to the grid continue to run.
The 5 generator can control the temperature, pressure, voltage, current and other parameters of the generator set automatically and adjust the flow of gas and cooling water to ensure the normal operation of the generator set through the process control software
For the coking enterprises, any power outage will cause huge loss, once the power tube, due to excessive pressure of coke oven coke oven gas rise, escape, are required to open the powder tube caused by smoke billowing from coke oven top emission, environmental protection is not allowed.
In addition the coke oven in the waste gas can not be exported, high pressure will cause internal leakage on the furnace body damage is also great, stop circulating ammonia circulation will cause great difficulties for gas cooling and tar derived; thus, using double loop uninterruptible power supply is crucial for enterprises.
