炭化条件对小麦秸秆炭棒燃烧性能的影响
Effect of Carbonization Conditions on the Combustion Performance of Wheat Straw Carbon Sticks
摘要
Abstract
In order to solve the shortcomings of straw briquettes, such as producing large amount of smoke during burning, failing to improve the calorific value due to its high volatile matter content, the briquettes were further carbonized for enhancing the calorific value and decreasing the amount of volatile component. The carbonization conditions, including carbonization temperature, heating rate and time, were investigated. Results showed that the calorific value of the produced carbon stick was increased obviously from 14. 48 MJ/kg to 19. 08 MJ/kg after heating at 300℃ for 1 h, with heating rate at 5℃/min. Density decreased from 1. 31 g/cm3 to 0. 99 g/cm3 , and the fixed carbon increased obviously to approximately 40% after carbonization. Besides, smoking time and fume decreased dramatically due to the drastical decrease of violate matters from 60% to 40%, approximately, while the yield was 52. 5%. This meets the demand of industry and daily life utilization.关键词
