Description

Technical Field

[0001] This invention discloses a burner management system, method, device, medium, and product based on skid-mounted design, belonging to the technical field of burner management systems. Background Technology

[0002] A burner management system (BMS) is an automated control system for industrial combustion equipment (such as boilers and furnaces). Its core function is to ensure the safety, stability, and efficiency of the ignition and combustion process. A typical BMS integrates an ignition system (such as an ignition gun and flame detector) and an instrumentation and valve management system (such as fuel valves, air valves, and pressure switches) to achieve automatic ignition, flame monitoring, combustion regulation, and safety interlock protection through collaborative operation. Currently, in many industrial applications, the ignition system and the instrumentation and valve management system often exist as two independent subsystems. This separate architecture leads to the following defects and shortcomings: 1. Low system integration: There is a lack of effective coordination and information exchange between the two systems, making it difficult to achieve true centralized and intelligent control, which increases the system complexity and operational difficulty.

[0003] 2. Safety and reliability risks: Due to insufficient coordination, there may be delays or vulnerabilities in ignition sequence control, fault diagnosis and safety interlock response, which increases the risk of safety accidents.

[0004] 3. Installation and maintenance are inconvenient. The separate systems result in complex on-site pipeline layout, large footprint, long installation period, and subsequent maintenance requires different systems, which is costly.

[0005] The main reason for the above defects is that traditional designs do not treat ignition and instrument control as an integrated functional unit and design them in a modular way. Summary of the Invention

[0006] The purpose of this invention is to provide a burner management system, method, device, medium, and product based on skid-mounted design, in order to solve the problem of low modularity in burner management in the prior art.

[0007] A burner management system based on skid-mounted design includes an operation control module, a logic control module, and a field module; The operation control module sends operation instructions to the logic control module, the logic control module sends control signals to the field module, the field module sends detection signals back to the logic control module, and the logic control module sends feedback signals back to the operation control module.

[0008] The operation control module is mounted on the distributed control system (DCS) in the central control room. The operation control module includes a line parameter setting submodule, a status monitoring submodule, and a remote operation submodule. The distributed control system is equipped with a field touchscreen that provides a human-machine interface.

[0009] The logic control module is integrated into a programmable logic controller (PLC) and includes an ignition logic execution submodule, a safety interlock submodule, and an adjustment control submodule.

[0010] The field module includes a valve submodule, a flame detector submodule, and an ignition device submodule. The valve submodule controls the ignition gas valve, fuel oil valve, and air valve of the burner. The flame detector submodule uses two intelligent flame detectors to detect small flames and the main flame at different installation angles. The ignition device submodule controls a high-energy igniter and a retractable ignition gun.

[0011] The programmable logic controller is located in the PLC control cabinet. The PLC control cabinet, intelligent flame detector, high-energy igniter, retractable ignition gun, ignition gas valve, fuel valve and air valve of the burner are integrated on the skid.

[0012] A burner management method based on skid-mounted design, using a skid-mounted burner management system, including a programmable logic controller and a distributed control system, which exchange data and work collaboratively through a standard industrial communication protocol.

[0013] The programmable logic controller performs safety protection, including automatic ignition sequence, real-time flame monitoring and main fuel trip, while the distributed control system performs optimization and regulation of the combustion process, including temperature control, flow regulation and air-fuel ratio control.

[0014] A computer device includes: a memory, a processor, and a computer memory stored in the memory and running on the processor. The processor executes the computer program to implement the aforementioned burner management method based on skid-mounted design.

[0015] A computer-readable storage medium having a computer program stored thereon, which, when executed by a processor, implements the aforementioned burner management method based on a skid-mounted design.

[0016] A computer program product includes a computer program that, when executed by a processor, implements the aforementioned burner management method based on a skid-mounted design.

[0017] Compared to existing technologies, this invention offers the following advantages: It solves the problem of low system integration, integrating previously separate systems into a physical and functional whole, achieving true collaborative operation and simplifying the system architecture. It enhances safety and reliability; the modular design makes the control logic more rigorous and the response faster. The integration of key safety components (such as dual quick-cut valves, three-valve manifolds, and redundant flame detection) strengthens the inherent safety of the system at the hardware level. It facilitates installation and maintenance; the skid-mounted design allows for immediate use by connecting only external utility piping and electrical signal lines, significantly reducing on-site installation workload, shortening the construction period, and facilitating subsequent maintenance and management. It optimizes control performance; the division of labor and cooperation between the local control cabinet and the DCS ensures both the speed and independence of ignition and safety interlocks, while also achieving centralized management of process optimization, resulting in better overall control performance.
