The results indicate that the heat transfer coefficient increase about fourteen percent between the bed and the wall and the one between the gas and horizontal tube increase about twenty two percent, it means pulsating promote heat transfer, Desulfurizing Characters Experimental Research on Pulsating Fluidized Bed With different initial SO_2 density, mean diametric of the calcium oxide and combustion temperature, the experimental results of desulfurization with pulsating or not indicate that the desulfurizing characters of the Rijke type self-exciting pulsating fluidized bed are the same with the conventional fluidized bed combustor, it is that the utilization ratio of the calcium oxide increasing with the initial SO_2 density, the desulfurizing combustion temperature has the best value and the utilization ratio of the calcium oxide reducing with the mean diametric of the calcium oxide.

脉动流化床脱硫特性实验研究对不同初始SO_2浓度、不同初始脱硫剂颗粒平均直径、不同燃烧区温度条件下脉动与非脉动状态下流化床内的脱硫实验研究表明，Rijke型自激式脉动流化床具有类似于常规流化床燃烧器的脱硫特性：固硫剂的CaO利用率随初始SO_2浓度的增加而增加，脱硫燃烧温度存在最佳值，以及CaO利用率随脱硫剂颗粒平均直径的增加而减小。

Quicklime is calcium oxide or calcium-magnesium oxide.

生石灰是氧化钙或钙镁氧化物。

In fact, silicon dioxide, aluminum oxide, ferric oxide, calcium oxide and sodium oxide are the main components of coal ash that influence on fouling and slagging.

由于我国煤炭种类繁多，煤中矿物质的成分和含量千变万化，给煤的结渣机理研究带来很多干扰因素，从中找出明确的规律不是一件易事。

The experiments show that one portion of amino organic compounds in the shell is changed to the volatilizable amine and the other portion is transformed to the involatile nitrate after pyrogenation.The organic compounds disappear completely at 600℃.They also show that the aragonite phase of calcium carbonate in pearl shell chang with temperature;the aragonite phase transforms to calcite at 500℃, but some of organic compounds is still residual;and calcium carbonate begins to decompose to calcium oxide at 600℃.

实验发现，贝壳中的氨基酸类有机物热降解后部分以胺的形式挥发出来，另一部分则转化为不可挥发的硝酸盐的形式，600℃有机物完全消失；同时，贝壳碳酸钙的文石晶相随温度而变化，500℃时转变为方解石结构，其中仍有部分有机物残留，600℃开始分解为氧化钙。

Test results show that the shear strength parameters of the fly ash with high calcium oxide content can make a notable change due to pozzolanic action and frost and thaw cycles, but for the fly ash with low calcium oxide content this phenomenon is not very obvious,and the influence of the frost and thaw cycles can be neglected.

试验结果表明，高氧化钙含量的粉煤灰的强度指标受上述两种作用的影响显著；低氧化钙含量的粉煤灰的强度指标在凝硬作用下也有所提高，但基本不受冻融作用的影响；干贮粉煤灰的渗透系数受凝硬和冻融作用的影响较小。

In order to extend use of calcium carbonate, the samples were modified by hydrazine hydrate, triethanolamine and sodium stearate. Hydrazine hydrate was 0.08%～0.24% of calcium oxide, triethanolamine was 0.1%～0.3% of calcium oxide, sodium stearate was 5% of calcium carbonate,modification time was 40 minute. Calcium carbonate has better active exponent and white degree.
