1 Filling amount: 30 tons of bamboo counted with liquor filled tank and circularly press the bamboo flakes for 3-4 minutes during boiling,(the data results from repeated experiments), if the filling amount is too less, the hardness is low, too much alkali remnant, and the pulp yield will be low; if the filling amount is too much, the cooking liquor can not be dried completed, and the circulation amount is too less, the electric current of circulating pump is too low, it will be difficult to cook, and there will be too much pulp knots with high hardness and less alkali remnant which may lead to unripe pulp.

3.1.1装锅量：竹子30吨是以液浸装锅和开中循环压竹片3——4分钟为计，（数据是根据多次实验得出的结果）如装锅量太小，硬度低，残碱大，浆得率低，装锅量太大蒸煮液无法完全送完，循环量小，循环泵电流小，蒸煮困难，浆节子多、硬度高、残碱小，有可能造成生浆。

And they end up predominantly in the fine particle fraction in the fly ash duringcombustion.When biomass sample is pretreated by using chemical fractionation method,the content of volatile alkali in fuels decreases clearly and large amount of available C1 andS is also leached.So,during combustion the vaporization amount of alkali reduces and theformation of fine particle fraction in the fly ash is limited.

而当样品在经水洗分离和酸洗分离的化学处理后，燃料中易气化部分的碱金属元素含量大幅减少，大量水溶态或酸溶态的S，Cl等非金属&催化性&元素同时也被分离脱除，从而导致燃料样品燃烧时的碱金属气化量下降，且在成灰过程中向细微颗粒转化的途径也受到较大的抑制。
