摘要
在流化床气化炉内,以空气为气化剂,对美国杏仁壳在680℃、700℃、730℃和780℃的温度下进行了气化实验,生成的燃气成分为:CO含量在15.4%~18.7%之间,H2含量一般高于10%,甲烷含量为1.7%~2.5%,CnHm的含量为0.6%左右。燃气热值多数在4152.7kJ/m^3~4839.5kJ/m^3。气化效率51%。实验表明,在气化温度为700℃的时候可以得到最大的燃气热值。
Experiments on the gasification of the American almond putamina were conduced by using air as the gasification matter in the gasification stove of fluidized bed with the temperature 680 ℃, 700 ℃ ,730 ℃ and 780 ℃. The results are as follows: the resultant gas compositions are CO、H2、 CH4 and CnHm whose proportions separately are about 15.4% - 18.7% ,10% ,1. 7% - 2.5% and 0.6% ;The heating value of gas is from 4 152.7 to 4 839.5 kJ/m^3 ; the gasification efficiency is 51%. It is shown that we can gain the biggest heating value when the gasification temperature is 700 ℃.
