ACS-GL boiler whole-process intelligent control system is designed and developed with world advanced fuzzy control technologyand possesses core algorithms, including self-learning, self-sensing, self-decision-making and autonomic regulation. It is an intelligent control system independent from SCM, PLC and DCS.

This system achieves precise control, primarily targeting steam pressure (for steam boilers), water supply temperature (for hot water boilers), boiler load, and steam drum pressure (for waste incineration boilers). It employs auxiliary control strategies for parameters including furnace chamber negative pressure, furnace chamber temperature, oxygen content, flue gas temperature, and material layer differential pressure.

The system performs comprehensive intelligent analysis of boiler operating conditions, accounting for variations in fuel calorific value and load changes. Based on this analysis, it sends real-time operational commands to various actuators.

For grate-firing boilers (e.g., chain-grate, reciprocating grate), it controls the coal supply system, fire grate, blower, and induced draft fan. For fluidized bed or pulverized coal boilers, it manages coal supply, primary air, secondary air, and induced air. For waste incineration boilers, it coordinates the stoker, drying grate, burning grate, full-combustion grate, primary air fan, secondary air fan, and induced draft fan.

This enables intelligent coordinated operation and automatic optimization, achieving the optimal air-fuel ratio, realizing economical boiler combustion, and ensuring the precise and stable operation of primary control targets. Ultimately, it truly intelligent boiler operation and delivers significant energy savings.

This system fundamentally transforms the traditional boiler operation mode, which relies primarily on manual control via control consoles, PLC, or DCS. It establishes a new intelligent operation paradigm where intelligent control is the primary means, and manual operation serves as the auxiliary means.

Scope of Application: This system is suitable for a wide range of boilers, including those used in power plants, cogeneration systems, heating systems, and industrial power boilers.

Applicable Boiler Types: Grate-firing boilers, circulating fluidized bed boilers, pulverized coal boilers, biomass boilers, bubbling fluidized bed boilers, and waste incineration boilers.

Uniqueness of the System:

● The ACS-GL boiler whole-process intelligent control system can be installed without changing the original appearance of the boiler.

● The system can be installed while the boiler is operational, without affecting normal production.

● After installation and commissioning, the system allows for flexible switching between the original manual control and the new automatic control.

● The installation cycle is short: hardware installation takes 1-3 days, commissioning takes 3-5 days, and operator training is completed within 15 days. Thereafter, the system operates normally. It is user-friendly, and operators without computer expertise can learn to operate it skillfully through training.

● After installation and commissioning, the effectiveness of the intelligent operation becomes immediately apparent compared to the original manual mode.

Realized Effects:

1. The system features high intelligence and advanced process management. After commissioning, it enables whole-process intelligent operation and achieves a long-term automatic control rate of over 95%, a leading standard in the field.

2. The master control is precise and stable. For example, it maintains the water supply temperature within ±1°C of the set value, or the main steam pressure within ±0.03 mPa of the set value in real-time.

3. Upgrading to the ACS intelligent control effectively reduces operator labor intensity by over 70%.

4. The system delivers significant fuel efficiency. Under identical conditions, it achieves a coal consumption reduction rate of over 3% compared to manual operation.

5. Equipped with safety limit settings and a fault diagnosis mechanism, the system guarantees operation within the safe operating range, thus significantly enhancing safety compared to the original operation.
