西北地区矿区低碳供热的技术经济分析
TECHNO-ECONOMIC ANALYSIS OF LOW-CARBON HEATING FOR MINING AREAS IN NORTHWEST CHINA
摘要
Abstract
The low-carbon heating retrofit of mining areas represents a pivotal direction in achieving China's goals of emission peak and carbon neutrality.By fully utilizing renewable energy and waste heat resources available in mining areas,restructuring the energy structure of mining areas is a key pathway to promoting low-carbon heating and low-carbon mining construction in mining areas.Based on different technical heating routes,this paper develops analytical models for a solar heating system,a mine water source heat pump heating system,a mine exhaust air source heat pump heating system,a regenerative electric electrode boiler heating system,and a coal-fired boiler heating system.Then,taking the heating of industrial factory buildings in a mining area of Yulin City,Shaanxi Province as an example,the heat load and resource characteristics are analyzed,and the capacity configuration,techno-economic,and environment of different heating systems are compared and analyzed.The analysis results show that:1)Low-carbon heating methods such as solar energy,mine water source heat pump,mine exhaust air source heat pump,and regenerative electric electrode boiler can all effectively replace the coal-fired boiler heating methods.2)Although the solar heating system has a relatively high initial investment cost,it demonstrates significant advantages in terms of annual comprehensive heating cost over the long term,and its CO2 emissions are only about 6.3%of those of the coal-fired boiler heating system,highlighting its out-standing environmental benefits.The annual comprehensive heating costs of both the mine water source heat pump heating system and the mine exhaust air source heat pump heating system are higher than that of the regenerative electric electrode boiler heating system,primarily due to electricity price impacts,while both exhibit considerable CO2 emission reduction benefits.The CO2 emission factor of the regenerative electric electrode boiler heating system is greatly influenced by the energy structure of the power system and the CO2 emission coefficient of the power grid.The findings provide decision-making support for the low-carbon development pathways of heating in mining areas.关键词
