Clean heating during winter season in Northern China: A review

Previous researchers found that bulk coal combustion for heating was considered as one of the most important sources of air pollution, and the replacement of coal combustion resulted in significant air quality improvement, health benefits and the reduction of CO2 emission. The clean heating forms an essential part of the energy revolution, thereby significantly influencing the rural lifestyle. The pilot program for clean heating has been launched recently. However, various challenges have remained which cannot be ignored. This study critically reviews the implications, research situation, technology, and methods associated with clean heating during winter season in Northern China. The status, technical routes, and various clean heating technologies in Northern China was introduced. The authors analyzed the advantages, disadvantages, and economics of various heating systems/methods, such as the air-source heat pumps, electric heating system, wall-mounted natural gas heater system, biomass pyrolysis cogeneration clean heating. The environmental benefits of clean heating options during winter in Northern China were evaluated based on the extensive analysis. The suggestions were presented regarding the promotion of clean heating technology.

Automated summary

Clean heating is crucial in improving air quality, enhancing health benefits, and reducing CO2 emissions, particularly in Northern China. Despite the benefits, challenges remain in implementing clean heating technology due to various factors such as technical limitations and economic considerations. The study evaluates different clean heating options and provides recommendations for promoting clean heating technology in the region.
