Main performance and features:

★ Pulverized coal easy to prepare and store: the raw coal is pulverized and sent into the pulverized coal warehouse for storage, and the high pressure wind sends the pulverized coal into the burner combustion;

★ Automatic ignition convenient and fast: pulverized coal combustion ignition using light diesel oil, high-energy igniter with the oil supply system to achieve automatic ignition;

★ Cyclone low nitrogen efficient combustion: using a multi-channel cyclone burner, through the adjustment of combustion-assisted air to make the pulverized coal in the furnace efficient and stable combustion;

★ Reasonable control and operation simple: reasonable adjustment of air distribution to make the internal heat load in the furnace uniform, reduce the furnace body wall hanging, coking, easy to operate;

★ System linkage use safety: according to different working conditions, it can realize automatic ignition, automatic tracking of outlet temperature, safety alarm, system linkage and other control modes for users to choose;

★ stable structure, long service life, simple maintenance, short construction period, and low civil engineering cost;

★ furnace body is equipped with explosion-proof valve, emergency flue gas release valve etc. 

PLC control system: 

The state mark of normal operation of pulverized coal furnace is by light diesel ignition heating, make pulverized coal fire normal combustion, pulverized coal normal combustion light diesel ignition system automatically stop running, adjust the reasonable ratio of pulverized coal combustion and air volume, make the furnace temperature, outlet flue gas temperature, tailing gas temperature control within a certain range to dry material, for different processes, measurement and control parameters selection will be different.

According to the need of the central control DCS system, the PLC system can communicate with the DCS system; The communication modes include Ethernet, Profibus DP, Profinet, Modbus RTU, Modbus TCP and point-to-point etc. That is, the PLC control system can exchange data with the central control DCS system through the above communication methods, so as to realize the remote control of the DCS system to furnace on site.
