摘要

针对当前燃煤电厂普遍存在的燃料成本高、低负荷稳燃性能弱及调峰能力不足等问题，基于电厂周边可再生能源状况，提出一种厂内光伏发电制氢制氧与燃煤锅炉掺氢掺氧协同的集成运行方案。通过构建全尺寸四角切圆燃煤锅炉数值模型，验证纯煤粉燃烧工况下温度场、组分含量及飞灰含碳量的模拟精度，为掺混优化提供基准参照。以厂内20 MW光伏发电制氢制氧的典型应用场景为例，系统研究3种氢气与氧气掺混方式对炉内燃烧效率、燃尽特性及NO

生成的影响规律。模拟结果表明：采用独立氢气喷口与一次风掺氧的协同掺烧模式可显著改善燃烧性能，炉膛出口飞灰含碳量较纯煤粉燃烧降低至0.97%，燃烧效率提升明显；同时，配合氢气燃烧产生的活性基团对NO

的还原作用，使烟气中NO

排放质量浓度降至294.0 mg/m

，较基准工况下降约25%。该模式通过可再生能源制氢制氧实现燃煤替代与燃烧优化双重效益，不仅能够降低煤耗，还可拓展燃煤锅炉稳燃负荷下限，为燃煤机组低碳化改造与灵活性提升提供了可工程化实施的技术参考路径。

Abstract

In response to current issues faced by coal-fired power plants

such as high fuel costs

weakly stable combustion performance at low loads

and insufficient peak-shaving capabilities

an integrated operational scheme is proposed based on the natural endowments of renewable energy surrounding the power plant

which utilizes photovoltaic power generation distributed in plants to produce hydrogen and oxygen via electrolysis of water

then to achieve hydrogen and oxygen co-firing in coal-fired boilers. By constructing a full-size

numerical model for a tangentially coal-fired boiler

the calculation accuracy of temperature field

species concentration

and carbon content in fly ash is verified under pure pulverized coal combustion conditions

which could provide a benchmark for optimization of hydrogen and oxygen blending. Based on the typical application scenario of a 20 MW photovoltaic power generation to hydrogen and oxygen production in the plant

the effects of three mixing methods of hydrogen and oxygen on combustion efficiency

burnout characteristics and NO

formation in the furnace are systematically studied. The results show that

a co-combustion mode which utilizes an independent hydrogen nozzle in conjunction with primary air mixing with oxygen can improve the combustion performance significantly. The carbon content in fly ash at the furnace outlet reduces to 0.97%

and the combustion efficiency is notably enhanced compared with that under pure coal combustion condition. At the same time

the reduction effect of reactive species generated by hydrogen combustion on NO

leads to a decrease in NO

emission mass concentration in the flue gas to 294.0 mg/m

which is decreased by about 25% compared with that under baseline condition of pure coal combustion. This model achieves dual-benefit of coal substitution and combustion optimization through hydrogen and oxygen production from renewable energy

which not only reduces coal consumption but also expands the lower limit of stable combustion load for coal-fired boilers. It provides a technically feasible implementation reference path for the decarbonized retrofitting and flexibility improvement of coal-fired units.
