1 Boiler Equipment Operation Analysis

Generally, the stable and safe operation of boiler equipment is the cornerstone of its development and also a prerequisite for ensuring the safe and stable operation of related user departments. Therefore, during the operation of boiler equipment, relevant personnel must pay attention to equipment maintenance issues. Only by ensuring the integrity of boiler equipment can the stable and safe operation of boiler equipment be achieved. Specifically, this means ensuring that all parameters can maintain balance during the operation of the boiler equipment.

1.1 Principles of Boiler Equipment Operation

As is well known, the stability of the operating status of boiler equipment is mainly measured by water quality, so it is necessary to strictly control the water quality in the boiler equipment. Only when the water quality meets the relevant standard requirements can the boiler equipment be in good operating condition. If there are a large number of impurities in the water quality of the boiler equipment and no treatment is performed, over time, scale will form in the boiler equipment, affecting the heat transfer efficiency of the boiler equipment, thereby reducing the quality of operation and causing resource waste. In severe cases, it can damage the internal pipe walls of the boiler equipment. Therefore, relevant personnel must ensure proper inspection of water quality. During the operation of the boiler equipment, the operation status should be controlled according to the operation standards of the boiler equipment. In terms of water quality, select water for the boiler equipment according to relevant standards and ensure proper filtration of the water, strictly controlling the impurity content in the water to reduce impurities. In addition, regular sewage discharge from the boiler equipment should be conducted, and effective measures should be taken to clean the dirt in the equipment. Properly adjusting the bubble water in the boiler equipment can prevent sudden changes in water level during operation, which can have a significant adverse impact on the steam production of the boiler equipment. At the same time, the operating load status of the boiler equipment should be monitored and controlled to prevent the operating load from exceeding relevant load standards, thus affecting the operational efficiency of the boiler equipment.

1.2 Principles to Follow for Safe Operation of Boiler Equipment

Boiler equipment can only save resources and prevent major safety accidents if it operates safely, thus avoiding potential risks to the life and property of relevant personnel. Therefore, during the operation of boiler equipment, it is necessary to adhere to corresponding principles and norms, strictly follow the relevant safety operation rules, supervise and control the operation mode and quality of the boiler equipment, providing the basic conditions for the safe operation and production of the boiler equipment. The primary principle to follow during the operation of the boiler equipment is timeliness. If operational faults are discovered during the operation of the boiler equipment, relevant personnel must promptly propose solutions and take effective measures based on the actual situation to ensure that the fault is resolved in the shortest time possible, reducing the harm caused by boiler equipment faults. At the same time, the safe operation of boiler equipment must also adhere to the principle of decentralization. When a fault occurs in the boiler equipment, the first priority is to ensure the safety of personnel and property. On this basis, identify the location of the fault in the boiler equipment and direct attention to other areas that do not affect the operation of the boiler equipment, minimizing losses and threats to the safe operation of the boiler equipment. Additionally, the operation of the boiler equipment must adhere to decisiveness. If a serious fault occurs during the safe operation of the boiler equipment and the cause cannot be identified in the shortest time, or if it cannot be transferred to other areas, relevant personnel must immediately stop the operation of the boiler equipment, identify the fault location, and importantly, cut off the power supply before searching for the fault to prevent accidents. The issue should also be reported to the relevant department immediately to increase their attention, ensuring that the fault is resolved in a timely manner.

2 Problems and Maintenance of Boiler Equipment Failures

2.1 Inspection and Maintenance of Equipment with Excessive Flue Gas Temperature
Boiler equipment is an important component of the safe operation of boiler equipment and plays an irreplaceable role. However, in actual operation, there are many unreasonable aspects in the layout of boiler equipment, which can damage related operational equipment, leading to unpredictable faults and problems during the operation of the boiler equipment. Among these, a more serious issue is the continuous rise in flue gas temperature. Therefore, relevant personnel must promptly analyze and study the causes of the problems in the equipment and resolve them. During the operation of the boiler equipment, there may be severe air leakage in the pulverizing system, furnace wall, flue, etc., which is an important reason for the continuous increase in flue gas temperature. To resolve this quickly, it is necessary to promptly inspect the main body of the boiler equipment and the corresponding pulverizing system to check for issues. If problems are found, the corresponding equipment should be repaired to reduce the operational risks of the boiler equipment.

2.2 Inspection and Maintenance of Coking and Ash Accumulation

When the boiler equipment is in operation, its internal temperature will rise. When the temperature reaches a certain height, the corresponding metal substances inside the boiler equipment will undergo chemical reactions, resulting in high-temperature coking phenomena inside the boiler equipment. Generally, coking phenomena often occur on the heated surfaces of the boiler equipment's furnace and convection heating surfaces, which are important areas for daily maintenance and cleaning of the boiler equipment. Impurities generated from low-temperature coking will adhere to the heated surfaces of the boiler equipment. During operation, the flue gas will contain a certain concentration of ash, which, after a period of reaction and sedimentation, will lead to ash accumulation. This mainly occurs in locations such as superheaters, air preheaters, and economizers. Therefore, during the daily operation of the boiler equipment, relevant personnel must pay close attention to the cleaning of these areas to ensure the safe and stable operation of the boiler equipment.

3 Optimization of Boiler Equipment Operation

3.1 Optimizing Combustion Methods

The oxygen content inside the furnace of the boiler equipment, the degree of moisture drying, and the speed of air intake are important factors affecting the combustion rate of the boiler equipment. During the operation of the boiler equipment, relevant personnel must carefully observe the operating parameters of the boiler equipment and control the oxygen content inside the furnace based on the parameter values. At the same time, appropriately adjust the ratio of fuel moisture and the relationship between primary and secondary air intake to improve the combustion efficiency inside the boiler equipment and enhance its operational effectiveness. During the safe operation of the boiler equipment, it is essential to manage the air intake speed, using primary air to adjust the coal powder to increase the oxygen content in the furnace, while secondary air can help reduce the temperature deviation inside the furnace, ensuring that the overall combustion efficiency of the boiler equipment remains at its highest state.

3.2 Improving Flue Gas Discharge Effectiveness

During the operation of the boiler equipment, there may be air leakage in the unit. Relevant personnel should effectively resolve this based on the actual situation of the boiler equipment, adjusting the relationship between the air supply and flue gas discharge to ensure optimal operational effectiveness of the boiler equipment while meeting combustion needs. Additionally, during the operation of the boiler equipment, it is advisable to use hot air as much as possible and reduce the use of cold air to enhance the utilization of the insulation layer. At the same time, relevant personnel should regularly clean the air preheaters to keep them clean and dry.
