摘要
当量比是决定燃料气化性能好坏的一个重要综合参数 ,而确定当量比的关键是能够知道燃料的理论空燃比 .论文研究发现 ,燃料理论空燃比与高位热值一样 ,都是燃料的特性参数 ,且二者之间呈近似线性关系 ,根据这一简单关系式 ,仅凭燃料的高位热值即可方便求得其理论空燃比 .以 2 8种不同燃料进行的计算表明 。
Equivalence ratio is an important factor affecting the gasification performance of a feedstock and the key to determining equivalence ratio is knowledge of the stoichiometrical ratio of air to fuel. It is found in this paper that stoichiometrical ratio (SR) of air to fuel and higher heating value (HHV) are all related to the characteristics of fuels and that there is a simple correlation between SR and HHV. Error analysis shows that the accuracy of calculation with the correlation is satisfactory for engineering requirements.
