太阳能+空气能复合能源——燃煤锅炉节能优化

Solar energy + air energy hybrid energy - energy-saving optimization of coal-fired boilers

摘要

针对甘肃地区煤矿传统燃煤锅炉供热存在的能耗高、污染重、运行成本大等问题，本文以靖煤能源大水头分公司为研究对象，提出“太阳能+空气能”复合能源系统替代原燃煤锅炉的节能改造方案。通过理论分析、系统设计、设备选型、实施过程及运行数据验证，该方案实现了煤矿洗浴用热的高效清洁供应。改造后系统年节约标煤约1682吨，减少CO₂排放约4313吨，投资回收期约2.55年，综合节能率达88.78%。研究结果表明，“太阳能+空气能”复合能源系统在西北干旱半干旱地区煤矿洗浴供热中具有显著的经济、环境和社会效益，为同类项目提供了可复制的技术路径和管理经验。

Abstract

In response to the issues of high energy consumption, severe pollution, and high operating costs associated with traditional coal-fired boiler heating in coal mines in Gansu Province, this paper takes Jingmei Energy Dahuishu Branch as the research object and proposes an energy-saving renovation scheme using a “solar + air source heat pump” hybrid energy system to replace the original coal-fired boiler. Through theoretical analysis, system design, equipment selection, implementation process, and operational data verification, this scheme achieves efficient and clean supply of heat for coal mine bathing. After renovation, the system saves approximately 1,682 tons of standard coal annually, reduces CO₂ emissions by approximately 4,313 tons, has an investment recovery period of about 2.55 years, and achieves a comprehensive energy-saving rate of 88.78%. The research results show that the “solar + air source heat pump” hybrid energy system has significant economic, environmental, and social benefits in coal mine bathing heating in arid and semi-arid regions of Northwest China, providing a replicable technical path and management experience for similar projects.
