As an important equipment for producing lime, the operating efficiency and product quality of lime kilns have a crucial impact on many industries. The traditional lime kiln control system often has problems such as inconvenient operation, low accuracy, and high energy consumption, which seriously restrict the improvement of production efficiency. As a professional enterprise in the industry, Jinyong Kiln is committed to providing users with lime kiln automation upgrade and transformation services. Through advanced technology and comprehensive solutions, it helps enterprises achieve intelligent, efficient, and sustainable development of lime kiln production.
1、 Current situation and problem analysis of lime kiln automation control system
（1） Current situation
At present, many lime kilns still use outdated control systems, mainly relying on manual operation and simple instrument monitoring. The control accuracy of key parameters such as temperature, pressure, and gas flow rate in the production process is limited, making it difficult to achieve precise control. Meanwhile, the recording and analysis of production data mostly rely on manual labor, lacking systematicity and real-time capability.
（2） Existing issues
Poor operational stability
Traditional control systems are susceptible to external interference, such as voltage fluctuations, environmental temperature changes, etc., which can lead to unstable operating conditions of lime kilns and affect the consistency of product quality.
Serious energy waste
Due to the inability to precisely control the combustion process, excessive fuel consumption often occurs. For example, when the temperature inside the kiln is too high, the fuel supply cannot be adjusted in a timely manner, resulting in unnecessary waste of energy.
High maintenance costs
The frequent malfunctions and inaccurate control of equipment lead to accelerated wear and tear of components, requiring frequent maintenance and replacement, which increases the maintenance costs of the enterprise.
Low production efficiency
The limitations of manual operation result in delayed adjustments and optimizations during the production process, longer production cycles, and difficulty in increasing output.
2、 Overview of the Automation Upgrade and Renovation Plan for Jinyong Kiln
（1） Overall objective
By introducing advanced automation technology, precise control, real-time monitoring, and intelligent optimization of the lime kiln production process can be achieved, improving production efficiency, reducing energy consumption, enhancing product quality, while reducing manual intervention and labor intensity.
（2） Specific measures
Hardware upgrade
(1) By using high-precision sensors such as temperature sensors, pressure sensors, gas concentration sensors, etc., various parameters inside the kiln can be collected in real-time and accurately.
(2) Update the controller equipment and select high-performance PLC (Programmable Logic Controller) or DCS (Distributed Control System) to improve the accuracy and stability of control.
(3) Install advanced actuators such as regulating valves, frequency converters, etc. to achieve precise adjustment of fuel, air, and other flow rates.
Software system development
(1) Design a user-friendly human-machine interface, allowing operators to intuitively understand the operating status inside the kiln, facilitating parameter settings and operational control.
(2) Develop intelligent control algorithms to automatically adjust the combustion process based on real-time data collected, achieving optimal temperature, pressure, and other controls. For example, using fuzzy control algorithms to automatically adjust the ratio of fuel and air according to the actual situation inside the kiln, improving combustion efficiency.
(3) Establish a production data management system to record, store, and analyze various data in real-time during the production process, providing a basis for production optimization and fault diagnosis.
