在能源利用与环保要求趋严背景下,焦炉煤气发电机组受企业关注。其选型应用中,功率匹配、煤气成分适应和环境适应是关键,具体如下:​

Against the backdrop of increasingly stringent requirements for energy utilization and environmental protection, coke oven gas generator sets have attracted the attention of enterprises. In its selection and application, power matching, gas composition adaptation, and environmental adaptation are key, as follows:

功率匹配:选对才高效​

Power matching: selecting the right one is efficient

企业选机组,功率要精准适配自身用电需求。功率选小,设备长期满负荷或过载,发电效率低、磨损快、寿命短、维修成本高。比如小型焦化厂电力需求 3000kW,选 2000kW 机组,生产高峰易过载报警,影响生产还增加维修开支。​

Enterprises should choose power units that accurately match their own electricity needs. Low power selection, long-term full load or overload of equipment, low power generation efficiency, fast wear and tear, short lifespan, and high maintenance costs. For example, if a small coking plant requires 3000kW of electricity and chooses a 2000kW unit, it is prone to overload alarms during peak production, which can affect production and increase maintenance costs. ​

功率选大也不行,长期低负荷运行,热效率降低,燃料浪费,还会因燃烧不充分产生积碳,影响设备性能。像中型钢铁企业选超大功率机组,负荷率不足 30%,燃料成本大增,维护也更困难。​

Choosing a high power is also not feasible. Long term low load operation will reduce thermal efficiency, waste fuel, and produce carbon deposits due to insufficient combustion, which will affect equipment performance. For medium-sized steel enterprises, choosing ultra high power units with a load rate of less than 30% increases fuel costs and makes maintenance more difficult. ​

煤气成分适应:净化到位保运行​

Gas composition adaptation: purification in place to ensure operation

焦炉煤气杂质多,焦油和粉尘会堵塞管道、磨损设备部件;硫化物和氮氧化物污染环境、腐蚀设备。要让机组稳定运行,必须净化煤气。​

Coke oven gas contains many impurities, and tar and dust can clog pipelines and wear equipment components; Sulfides and nitrogen oxides pollute the environment and corrode equipment. To ensure stable operation of the unit, it is necessary to purify the gas. ​

常用多级净化:先用旋风除尘器分离大颗粒粉尘,再用电捕焦油器高效除焦油;脱硫采用湿法与干法结合,先吸收硫化氢,再用吸附剂深度脱除微量硫化物,降低杂质含量,保障机组稳定运行。​

Commonly used multi-stage purification: first use a cyclone dust collector to separate large particle dust, and then use an electrostatic tar precipitator to efficiently remove tar; The desulfurization adopts a combination of wet and dry methods, first absorbing hydrogen sulfide, and then deeply removing trace sulfides with adsorbents to reduce impurity content and ensure stable operation of the unit. ​

环境适应:因地制宜很重要​

Environmental adaptation: adapting to local conditions is important

不同环境对机组要求不同。高温地区,需强化散热,可加大散热器面积或采用强制风冷、水冷技术,避免设备过热影响性能。​

Different environments have different requirements for the unit. In high-temperature areas, it is necessary to strengthen heat dissipation by increasing the area of the radiator or using forced air cooling or water cooling technology to avoid equipment overheating affecting performance. ​

高海拔地区空气稀薄,氧气不足,会降低机组功率。需优化进气系统,如用涡轮增压技术增加进气量,保证正常燃烧和功率输出。​

The thin air and insufficient oxygen in high-altitude areas will reduce the power of the unit. It is necessary to optimize the intake system, such as using turbocharging technology to increase the intake volume, to ensure normal combustion and power output. ​

多灰尘环境要加强设备密封和空气过滤;高湿度环境需对设备做防潮处理,防止电气元件受潮短路,确保机组在复杂环境稳定运行。

Strengthen equipment sealing and air filtration in dusty environments; High humidity environments require moisture-proof treatment of equipment to prevent electrical components from being affected by moisture and short circuiting, ensuring stable operation of the unit in complex environments.
