該研究的主要目標是通過將流化床生質燃料系統與史特林發動機相結合,增強和改進熱電聯產(CHP)系統。強調系統穩定性的重要性,特別注意確保CHP系統的可靠運行。在史特林發動機和加熱端水盤的操作中建立穩定性至關重要,同時保持流化床及其操作條件的穩定性。此系統裝置中,流化床燃燒器上方放置了一張桌子。在這個桌子上,放置了一座史特林發動機,位於燃燒器出口正上方以發電。
在操作區間測試中,為了確保空氣流量為50~60升/分鐘,流化床生質物的進料速率變化在9.5至17克/分鐘之間。為了優化實驗條件,採用了田口法,列舉了9種不同的實驗條件。這些條件著重於流化床的操作區間、物料溫度和出口溫度。
優化後,選定的實驗條件被用來進行煙道氣體分析,包括測量氧氣、二氧化碳、一氧化碳和氮氧化物,以評估燃燒效率。這個實驗裝置使流化床和史特林發動機的結合能夠運行行熱電聯產。
The primary goal of this research was to enhance and make advancements to a combined heat and power (CHP) system by integrating a fluidized bed biofuel system with a Stirling engine. Emphasizing the importance of system stability, particular attention was given to ensuring the reliable operation of the CHP system. It was crucial to establish stability in both the Stirling engine and the heated end of the water tray and maintain stability in the fluidized bed and its operating conditions. An experimental setup was designed, with a table over the fluidized bed combustors. In this table, a Stirling engine was placed and linked to the outlet of the combustor to produce electricity.
During the operation interval test, the feed rate of the biomass in the fluidized bed varied between 9.5 to 17 g/min to ensure a consistent air flow rate of 50~60 l/min. To optimize the experimental conditions, the Taguchi method was employed, resulting in the enumeration of 9 different sets of experimental conditions. These conditions focused on the fluidized bed operating area, material temperature, and outlet temperature.
After optimization, the selected experimental conditions were used to perform flue gas analysis, including measurements of oxygen, carbon dioxide, carbon monoxide and nitrogen oxide, to evaluate the combustion efficiency. The experimental setup enabled the operation of a combined heat and power generation system that integrated the fluidized bed and Stirling engine.
