近日，陕煤运电1号机组顺利完成首次生物质燃料掺烧试验，标志公司在煤电机组生物质耦合发电领域实现突破。试验依托现有设备，试烧果汁厂废果泥30吨，期间机组主要运行参数、环保指标稳定，累计节省标煤约4吨，减排二氧化碳近10.4吨。

Recently, the No. 1 unit of Shaanxi Coal Power & Electric Power successfully completed its first trial of blending biomass fuel into coal-fired power generation. This marks a breakthrough for the company in the field of biomass-coupled power generation of coal-fired power units. The trial was conducted using existing equipment, and 30 tons of waste fruit pulp from the juice factory were used for testing. During the trial, the main operating parameters and environmental indicators of the unit remained stable. Approximately 4 tons of standard coal were saved and nearly 10.4 tons of carbon dioxide were reduced.

实现生物质燃料稳定掺烧，关键在于生物质的选用、制料及燃烧调整。试验进行前，陕煤运电成立专项工作专班，深入调研周边农业及畜牧业发展情况，根据运城地区苹果资源丰富、加工产业链齐全、果泥等固废处置难度大的实际，初步选定果汁厂废果泥作为生物质燃料，创新构建“苹果加工产生固废—火电机组免费掺烧处置”产业链延链合作模式，为后续常态化运行奠定基础。

To achieve stable combustion of biomass fuel, the key lies in the selection of biomass, material preparation, and combustion adjustment. Before the trial was conducted, Shaanxi Coal Transportation Electricity established a special working team to conduct in-depth research on the development of agriculture and animal husbandry in the surrounding areas. Based on the actual situation in Yuncheng region, where there is abundant apple resources, a complete processing industry chain, and great difficulty in disposing of fruit waste such as fruit pulp, they initially selected the waste fruit pulp from the juice factory as the biomass fuel. They innovatively constructed a "apple processing generating solid waste - free blending and disposal by thermal power units" industrial chain extension cooperation model, laying the foundation for the subsequent regular operation.

据测算，项目常态化运行后，年可消纳废果泥约6万吨，减排二氧化碳近2.2万吨，节省燃料费用约550万元，经济与环保效益显著。

According to the calculation, after the project is in regular operation, it can consume approximately 60,000 tons of waste fruit pulp annually, reduce carbon dioxide emissions by nearly 22,000 tons, and save approximately 5.5 million yuan in fuel costs. The economic and environmental benefits are remarkable.

此外，针对废果泥纤维含量高、质量轻、燃点低，易造成研磨系统匹配失衡、燃料入口风温偏差大等问题，陕煤运电制定“单磨混烧”技术路线。通过现场调试、分组比对，优化确定最佳研磨参数，实现制粉系统与废果泥研磨稳定匹配。

Furthermore, due to the high fiber content, light weight, low ignition point, and the potential for causing imbalance in the grinding system and significant deviations in the wind temperature at the fuel inlet, Shaanxi Coal Transportation and Electricity has formulated the "single grinding combined combustion" technical route. Through on-site debugging and group comparison, the optimal grinding parameters were optimized and determined, achieving stable matching between the grinding system and the waste fruit pulp grinding process.

同时，陕煤运电组建专业技术团队，模拟测算不同掺烧比例可能导致的燃烧扰动，针对性制定一次风流量、风压、热风挡板开度应对预案，有效解决生物质燃料混合不均、燃烧不稳定等难题，最终达成20%的最大掺烧比例，为后续商业化运行提供数据参考。

Meanwhile, Shaanxi Coal Transportation and Electricity established a professional technical team to simulate and calculate the possible combustion disturbances caused by different blending ratios. They specifically formulated response plans for primary air flow, air pressure, and hot air damper opening, effectively solving problems such as uneven blending of biomass fuels and unstable combustion. Eventually, they achieved a maximum blending ratio of 20%, providing data references for subsequent commercial operations.

下一步，陕煤运电将持续优化生物质掺烧技术，深化与上下游企业协同合作，构建“资源+技术+应用”一体化产业链，为陕煤集团煤电机组生物质耦合发电规模化应用提供可复制、可推广的“运电方案”，为绿色低碳发展贡献力量。

Next, Shaanxi Coal Transportation Electricity will continue to optimize the biomass blending combustion technology, deepen collaboration with upstream and downstream enterprises, and build an integrated industrial chain of "resources + technology + application", providing a replicable and scalable "transportation electricity solution" for the large-scale application of biomass coupling power generation in Shaanxi Coal Group's coal-fired power plants, and contributing to green and low-carbon development.
