Product Description
1.Auxiliary equipment: for boiler induced draft fan, forced draft fan, feed water pump, grate, etc for centralized control. 
2.Automatic monitoring and display on furnace negative pressure, feed water pressure, water level of steam drum, steam temperature and other thermal parameters.
3.It has the ultra-low water level, low water, high water level, ultra-high pressure alarm function.
4.It has ultra-low water level,ultra high pressure interlock protection and automatic feeding water function. 
5.It has simulated water level red and green double color display function. 
6.Can be applied to oil/gas fired boiler flame out alarm and interlock protection function. 
7.Boiler control cabinet electrical components can use Chint Brand or imported Schneider Brand.

Frequency Conversion Brief Introduction

1.Frequency converter is a power control conversion device to convert normal power supply (50Hz or 60Hz) to another frequency power by inner power semiconductor on/off behaviors, to control electric motors in variable speed operations. 
2.The frequency inverter is mainly consisted of rectifier (AC to DC), filter, inverter (DC to AC), braking unit, drive unit, detection unit and micro processing unit etc
3.Our boiler control cabinet adopts ABB or Schneider Brand frequency Converter to realize boiler and accessories accurate detection and perfect frequency conversion. It greatly reduces power consumption, improves equipment applicability,compatibility and extends operation life. And it maximizes automatic control.
PLC control system
The boiler PLC control, is a new technology developed in recent years, it includes the microcomputer hardware and software, automatic control, boiler energy conservation.
We use Siemens PLC on boiler control system..
1.It has visual and concentrated display of boiler operation parameters and can display liquid level, pressure, temperature condition. 
2.Modify the system control parameters and change limit of liquid level, pressure, temperature and so on.
3.Microcomputer controlling fans, water pump and coal feeder,grate and slag remover, greatly reduces boiler consumption and improve boiler efficiency.
4.As boiler control device, its main task is to ensure boiler safe, stable and economic operation and reduces the labor intensity of operators. In the boiler control system controlled by computer, there's a very critical security mechanism. It can set up multi-point sound and light alarm and automatic interlock shut down. Put an end to major accidents caused by human negligence
