The gas station is the main device used to produce gas to fuel furnace and spray tower. Gas stations distributed control system of our company is dedicated to the design of gas station facilities, through all the equipment monitoring and control of the whole gas station, in order to achieve the whole gas system safety, effective, stable operation, production of standard gas. The system is safe, reliable, advanced, mature technology has the advantages of simple operation, easy maintenance.

The function of the system:

- stoker control system: the furnace coal detection meter to detect coal level limit automatically start signal as the signal source, the gas furnace coal stoker circulating control.

Li Qing control system: the ash machine through the ash layer height sensor and control system, cleaning machine to work, cleaning machine stops working when the ash layer is reduced to a certain height.

In the air blower control system: by gas furnace gas outlet pressure as the feedback signal and the frequency converter, air blower, according to the preset pressure value, automatic control loop.

In the saturation temperature control system: by PLC according to the bottom of the saturation temperature detecting instrument, alarm opening state automatic control steam electric valve.

- drum water level control system: liquid level sensor set on the drum level display control for intelligent instruments with liquid level signal, through the upper and lower signal to control the water supply valve instrument set.

- gas compressor control system: the gas outlet pressure of compressor as the feedback signal and the frequency converter, pressure machine, according to the preset pressure value, automatic control loop.

- purification equipment control system: by PLC complete automatic control detarrer and electrostatic precipitator, electric valve.

- Gas Desulfurization Control System: by PLC complete automatic control and desulfurization tower and related equipment.

Performance characteristics:

This system can achieve a high degree of automation: automation equipment control, management of the gas station, reduce the operation cost and labor intensity.

This system has perfect locking function: to lock on the whole system, automatic equipment start and stop control, and easy to modify the interlock relationship.

This system is easy to operate: a centralized automatic selection, centralized manual and local manual in three ways.

This system has the function of visual display: real-time data acquisition and centralized monitoring by remote communication module. To monitor each fan, water pump, valve, water level, can directly display the real-time data such as temperature, pressure everywhere in the host computer, and has the historical data query function.

This system has the function of alarm and alarm query function: convenient fault diagnosis and repair equipment.
