Abstract

This paper proposes a novel technology for waste heat recovery from a coal-fired curing barn flue gas, which can reduce simultaneously the flue gas pollutants. The upper and lower shed tobacco leaves are used as the research object during the curing of tobacco leaves in the rural curing tobacco house. The temperature and the humidity are monitored during the curing process, the change in the appearance of the tobacco leaves is observed. The desulfurization and denitration system can improve the uniformity of the overall tobacco leaves temperature and humidity, and can realize the integration of waste heat recovery of coal-fired boilers and flue gas pollutants treatment. An experiment is carried out and the results show that the technology can save energy to the greatest extent while ensuring the quality of tobacco leaves.
