本文目的,在於利用一具完整量測功能的實驗性固定爐床式燃燒爐,以實驗的方式探討木材燃料在批次燃燒的過程中,其燃燒特性受輔助燃燒空氣的影響,主要考慮的實驗參數有:空氣總量,上下火空氣配比,與上火空氣位置;並進一步依其特性利用空氣調節來對燃燒進行控制,文中主要的比較討論依據為量測所得的燃燒室內各點的溫度變化.
研究結果顯示,輔助燃燒空氣量愈多,則燃燒速率愈快,但燃燒溫度不見得因而提高;在相同空氣量下,下火空氣量愈大則燃燒速率愈快,燃料熱釋放率愈快;在燃燒溫度控制上,藉由調整不同燃燒階段的供給空氣量,可以得到較為穩定的燃燒溫度.
A experimental investigation of the combustion of wet wood is presented. The aim of this paper is to study the effect of air supply and distribution on wood combustion, the variables considered includes:(1)the total air flux, (2)the ratio of under-fire air/over-fire air, (3)the position of over-fire air, (4)control of under-fire air supply. According to the results presented, it is concluded that the combustion gas temperature and combustion rate are most influnced by the factors (1) and (2). It is also concluded that we can smooth the variation of combustion gas temperature by controlling the supply of under-fire air.
