电厂入厂煤与入炉煤热值差偏大问题分析

Problem of the Great Difference Between Coal as Received and Coal as Fired in Thermal Power Plant

火力发电厂入厂煤与入炉煤热值差在燃料管理和技术监督中占重要作用。针对某电厂热值差超出电力行业对电厂热值差考核指标的情况,对该电厂设备性能、采样方式等方面进行实地排查,对电厂燃料管理的实际条件提出相应的建议。

The difference between the caloricity of the coal before and after storage is an important indicator of the fuel management of the plant.The caloricity difference is found to be serious "excessive" judged according to industry standard in a power plant.To deeply understand the casue,we carried out on-site inspections on the equipment performance and field screening of sampling process.A series of problems are identified.Corresponding countermeasures are proposed considering the reality of the power plant.
