工业尾气发电机组的应用与发展
工业尾气发电技术适用于冶金行业可燃尾气发电领域。在铁合金、钢铁、化工等行业的生产过程中,会产生大量的可燃工业尾气,如高炉煤气、转炉煤气、焦炉煤气、兰炭尾气、电石尾气等。这些尾气如果直接排放,不仅造成严重的资源浪费,还会对环境产生污染。工业尾气发电技术正是解决这一问题的有效途径。
Industrial exhaust gas power generation technology is applicable to the field of combustible exhaust gas power generation in the metallurgical industry. In the production process of industries such as ferroalloys, steel, and chemicals, a large amount of combustible industrial exhaust gas is generated, such as blast furnace gas, converter gas, coke oven gas, blue carbon exhaust gas, and calcium carbide exhaust gas. If these exhaust gases are directly emitted, they not only cause serious waste of resources, but also pollute the environment. Industrial exhaust gas power generation technology is an effective way to solve this problem.

在技术指标方面,先进的工业煤气内燃机发电技术可实现机组发电效率超过37%,脱硝后氮氧化物排放可控制在较低水平,机组运行润滑油消耗低。以某铁合金项目为例,安装多台燃气内燃发电机组及配套的煤气储存、加压、降温、精处理系统,利用高碳铬铁密闭炉副产工业煤气发电,年发电量可达数千万千瓦时,折合年节约标准煤数万吨,减少二氧化碳排放数万吨。
In terms of technical indicators, advanced industrial gas internal combustion engine power generation technology can achieve a unit power generation efficiency of over 37%, control nitrogen oxide emissions at a lower level after denitrification, and reduce the consumption of lubricating oil during unit operation. Taking a certain ferroalloy project as an example, multiple gas internal combustion generator sets and supporting gas storage, pressurization, cooling, and refining systems are installed to generate electricity using industrial gas as a byproduct of a high carbon ferrochrome closed furnace. The annual power generation can reach tens of millions of kilowatt hours, equivalent to saving tens of thousands of tons of standard coal and reducing tens of thousands of tons of carbon dioxide emissions.
在大型工业尾气发电项目中,可采用锅炉+汽轮发电机组的配置方式。例如兰炭尾气发电项目采用超高温亚临界兰炭尾气锅炉搭配中间一次再热直接空冷凝汽式汽轮机和发电机,将低热值高污染物的兰炭尾气转化为清洁能源,年发电量可观,真正实现了资源的快捷利用和变废为宝。此外,利用高炉、转炉富氢尾气作为发电原料,配置集装箱式发电机组及配套气体预处理设备,可实现年发电量数千万千瓦时,自发自用,每年可节约大量标准煤,减排二氧化碳数万吨。
In large-scale industrial tail gas power generation projects, a configuration of boiler+steam turbine generator unit can be adopted. For example, the Lantan tail gas power generation project uses an ultra-high temperature subcritical Lantan tail gas boiler combined with an intermediate reheating direct air-cooled condensing steam turbine and generator to convert low calorific value and high pollutant Lantan tail gas into clean energy. The annual power generation is considerable, truly realizing the efficient utilization of resources and turning waste into treasure. In addition, using hydrogen rich tail gas from blast furnaces and converters as power generation raw materials, configuring containerized generator sets and supporting gas pretreatment equipment, can achieve an annual power generation of tens of millions of kilowatt hours, self use, save a large amount of standard coal every year, and reduce tens of thousands of tons of carbon dioxide emissions.
内燃机烟气余热发电技术不增加明显额外的燃料消耗,实现了能源的梯级与快捷利用。它不仅是企业降本增效的利器,更是工业领域迈向绿色、低碳、可持续发展的重要实践。在碳达峰、碳中和目标背景下,工业尾气发电作为一种将工业废弃物转化为清洁能源的技术,具有广阔的应用前景。未来,随着燃烧控制技术、余热回收技术和烟气净化技术的不断进步,工业尾气发电机组的发电效率将进一步提高,排放指标将进一步降低,应用范围也将从传统的冶金行业向更多产生可燃尾气的工业领域拓展。
The internal combustion engine flue gas waste heat power generation technology does not increase any additional fuel consumption, achieving energy cascading and efficient utilization. It is not only a powerful tool for enterprises to reduce costs and increase efficiency, but also an important practice for the industrial sector to move towards green, low-carbon, and sustainable development. Against the backdrop of carbon peak and carbon neutrality goals, industrial exhaust power generation, as a technology that converts industrial waste into clean energy, has broad application prospects. In the future, with the continuous advancement of combustion control technology, waste heat recovery technology, and flue gas purification technology, the power generation efficiency of industrial exhaust gas generators will be further improved, emission indicators will be further reduced, and the application scope will also expand from the traditional metallurgical industry to more industrial fields that generate combustible exhaust gas.
