摘要: 在燃煤价格高企及电煤价格倒挂等因素影响下,为降低发电成本,燃煤火力发电厂普遍采取扩大燃用煤种范围的燃煤掺烧策略。降低燃煤品质可以实现综合标煤单价下降,提升发电项目的盈利能力。研究了燃煤品质的2个主要参数——发热量和硫分对发电成本的影响,构建了基于发热量和硫分的发电成本模型,可为发电企业燃煤掺烧成本测算提供有益参考。

Abstract: Under the influence of soaring coal price and the price contradiction between the higher coal price and the lower on-grid power price, blending coal is widely adopted by thermal power plants to reduce the cost of generation. Firing the power coal of low calorific value can help the plants to achieve unit price drop of the comprehensive standard coal, thereby to improve the profitability of power generation projects. This paper aims to study the impacts of the two main parameters of power coal quality, i.e., the calorific value and the sulfur content value, on the cost of electricity generation. Based on the research on the two parameters, a model of electricity generation cost is established, which could provide useful reference for the calculation of blending coal cost.

Key words: thermal power plant, generation cost, calorific value, sulfur content value
