Core Technologies and Functions
Advanced DCS Control System
Utilizes a Distributed Control System (DCS) to provide highly reliable and customizable solutions for the entire boiler control process. The integrated design of the control system enhances operational flexibility and precision.
Fully Automatic Intelligent Control
The automatic control system integrates key operational parameters such as fuel supply, air flow regulation, and bed thickness. Intelligent algorithms automatically adjust parameters to achieve optimal combustion efficiency and meet environmental standards.
Combustion System Management
Primary and secondary fans work together to ensure adequate oxygen supply, optimizing combustion. Specifically designed air caps and preheaters ensure that air reaches the ideal temperature before entering the combustion chamber.
Precise Control of Fuel and Air
The control of the coal feeder, primary, and secondary air flow ensures an optimal ratio of fuel and air. High-efficiency fuel utilization significantly reduces the emissions of unburned fuel.
Environmental Design
The control system reduces nitrogen oxides (NOx) and sulfur dioxide (SO2) emissions to comply with strict environmental regulations. The system design also includes comprehensive flue gas treatment, effectively removing dust and particulate matter.
Furnace Safety Supervisory System (FSSS)
Monitors the operation of the boiler comprehensively and responds promptly to any potential safety issues.
Control System Organization and Network Architecture
Organization Structure:
The system consists of the following components:
Engineer Station
Operator Station
Server Station (optional)
Field Control Station
Industrial Control Network
Engineer Station:
Responsible for system configuration, modifications, and downloading.
Functions include: Database, graphics, control algorithms, and report configuration / Parameter configuration / Configuration of operator stations, field control stations, and process I/O modules / Data downloading and incremental downloads
Operator Station:
Monitors and manages the boiler status.
Functions include: Centralized management and monitoring of system data / Display of process flow diagrams / Report printing / Control operations / Historical trend display / Log, alarm records, and management
Field Control Station:
Responsible for field signal collection, such as remote transmitters, valve signals, etc., transmission, control, interlocking control algorithms, and control outputs.
Transfers data and diagnostic results to the operator station via the system network.
Server Station (Optional):
Provides services for historical system data.
Network Structure:
The network structure consists of three parts:
System Network (SNET)
Control Network (CNET)
Management Network (MNET) (optional)
System Network (SNET):
