杂质去除​

Impurity removal

合金尾气含粉尘等杂质，会磨损发动机部件。需在进气管道前端设旋风、布袋等高效除尘设备。如某铜合金厂起初未除尘，发动机运行三月后严重磨损，加装布袋除尘器后，除尘效率超 99%，问题解决。​

Alloy exhaust contains impurities such as dust, which can wear down engine components. Efficient dust removal equipment such as cyclones and bags should be installed at the front end of the intake duct. If a copper alloy factory initially did not remove dust, the engine would suffer severe wear after running for three months. After installing a bag filter, the dust removal efficiency exceeded 99%, and the problem was solved. ​

成分调节​

Ingredient regulation

尾气中一氧化碳、氢气等可燃成分浓度要合适，否则燃烧不稳定甚至有爆炸风险。可装在线气体分析仪，配自动调节装置，依浓度调节尾气与空气混合比例。如锌合金冶炼尾气发电项目，用 PLC 系统依分析仪数据，自动调进气阀门开度，稳定可燃成分浓度。​

The concentration of combustible components such as carbon monoxide and hydrogen in exhaust gas should be appropriate, otherwise the combustion will be unstable and there may even be a risk of explosion. Can be equipped with an online gas analyzer, equipped with an automatic adjustment device, to adjust the mixing ratio of exhaust gas and air according to concentration. For the zinc alloy smelting tail gas power generation project, a PLC system is used to automatically adjust the opening of the intake valve based on analyzer data, stabilizing the concentration of combustible components. ​

温度控制​

Temperature control

尾气温度常过高，会降低润滑油黏度、引发爆震。要设水冷式换热器等冷却装置，降低尾气温度。某铝合金厂尾气从 400℃冷却至 150℃，满足了发电机组进气要求。

The exhaust temperature is often too high, which can reduce the viscosity of lubricating oil and cause detonation. Cooling devices such as water-cooled heat exchangers should be installed to reduce the exhaust gas temperature. The exhaust gas from a certain aluminum alloy factory was cooled from 400 ℃ to 150 ℃, meeting the intake requirements of the generator set.

发电参数监测​

Power generation parameter monitoring

密切留意输出电压、电流、频率。电压不稳易损用电设备，频率偏差影响电力质量与电网接入。通过智能电表和电力监测系统采集数据，参数异常时自动报警并调节。如某镍合金发电站用远程监控系统，电压波动 ±5% 时，系统自动调励磁电流稳定电压。​

Pay close attention to the output voltage, current, and frequency. Unstable voltage can easily damage electrical equipment, and frequency deviation affects power quality and grid connection. Data is collected through smart meters and power monitoring systems, and automatic alarms and adjustments are made when parameters are abnormal. If a nickel alloy power station uses a remote monitoring system, when the voltage fluctuates by ± 5%, the system automatically adjusts the excitation current to stabilize the voltage. ​

发动机状态监测​

Engine condition monitoring

发动机是核心，要监测机油压力、冷却液温度、转速等。机油压力低影响润滑，冷却液温度高易致发动机过热。通过压力、温度等传感器传输数据，实现故障预警。某钴合金厂在发动机装多个传感器，提前发现并解决多次潜在故障。

The engine is the core and needs to monitor oil pressure, coolant temperature, speed, etc. Low oil pressure affects lubrication, and high coolant temperature can easily cause engine overheating. By transmitting data through sensors such as pressure and temperature, fault warning can be achieved. A certain cobalt alloy factory installed multiple sensors in the engine to detect and solve potential faults in advance.

尾气排放监测​

Exhaust emission monitoring

发电时仍要监测尾气排放，安装设备监测二氧化硫、氮氧化物、颗粒物等浓度，确保达标。超标时排查燃烧、尾气处理装置等问题并整改。如某铅合金厂因活性炭吸附饱和未换，致二氧化硫超标停产，更换并加强监测后复产。​

During power generation, it is still necessary to monitor exhaust emissions and install equipment to monitor concentrations of sulfur dioxide, nitrogen oxides, particulate matter, etc., to ensure compliance with standards. When exceeding the standard, investigate and rectify issues with combustion and exhaust treatment devices. If a lead alloy factory fails to replace activated carbon due to saturation adsorption, resulting in excessive production of sulfur dioxide, it will resume production after replacement and strengthened monitoring. ​

防火防爆措施​

Fire and explosion prevention measures

合金尾气易燃易爆，运行区要设防火隔离带，严禁烟火。安装可燃气体泄漏报警装置，搭配通风系统。电气设备采用防爆型，避免电火花引发爆炸。某镁合金厂车间装多个探测器，全方位监测泄漏，保障安全。

Alloy exhaust gas is flammable and explosive. Fire isolation zones should be set up in the operating area, and smoking and open flames are strictly prohibited. Install a combustible gas leak alarm device and equip it with a ventilation system. The electrical equipment adopts explosion-proof type to avoid explosions caused by electric sparks. Multiple detectors are installed in the workshop of a magnesium alloy factory to comprehensively monitor leaks and ensure safety.
