It is found that the fouling rate is lowered during subcooled fow boiling by carrying gas injection, and the influence of carrying gas injection on fouling of convective heat transfer is more obvious than that of subcooled flow boiling; morphology of CaCO〓 crystallization fouling exhibits self-similarity and the fractal dimensions of CaCO〓 crystallization fouling are determined from the gray scale distribution of the SEM images by box-dimension method. The value of the crystallization fouling surface fractal dimensions reveals the complexity of the surface, and can be used as an import parameter for the investigation of influence of carrying gas injection on scale formation.

实验发现：引入载气，过冷流动沸腾结垢速率降低，但引入载气对过冷流动沸腾结垢速率的影响要弱于对对流传热结垢速率的影响；CaCO〓结晶垢具有统计自相似性，即分形特征；用盒子维法测定了CaCO〓结晶垢的分维值，分维值的大小反映了换热面上生成的结晶垢表面复杂程度，可用于描述引入载气对污垢的形成作用。

There are a few defects in existing processes of biomass gasification, for example using air as gasifying medium, N2 and tar content of the gas is high, and the calorific value is as low as 5000kJ/N in3. The technology of a circulating fluidized bed is still tentative at laboratory level. Through direct pyrolyze biomass, we can get product gas with high heating value (l4000kJINm3), but gas yield ratio is low (O.35m3/kg).

目前的生物质热解气化技术的现状是：以空气为气化剂的气化方式，得到的气体N_2和焦油含量高，热值一般在5000kJ/Nm~3左右；流化床气化工艺操作复杂，推广应用存在较多困难；直接干馏热解，虽气体的热值高（14000kJ/Nm~3），但产气率低（0.35m~3/kg）。

在鼓泡透明玻璃反应釜里模拟渗漏系统气体穿越多孔隙砂层形成水合物的过程实验，分析了气体迁移对气体水合物形成时气液界面的传质传热性质影响，表明实验中气体迁移形成水合物的过程是一种相平衡曲线动态移动的过程；在形成水合物的气—液界面存在具有一定厚度的过渡层，只要过渡层内气体达到饱和即可形成水合物；气体在迁移中不断形成水合物并在孔隙中形成过压，导致地层骨架的力学破裂和失稳；必须建立一个新的水合物相图以适应气体迁移形成水合物过程的这种新特性。
