The synthetic gas and ash composition heat transfer and flow in vertical pipe of coal gasifier are simulated and analyzed by the theory and program presented. The temperature、velocity and concentration variations of synthetic gas and ash composition are accomplished. The influences of coal gasifier working condition and vertical pipe parameters on the gas and ash cooling process are discussed. The law of solid-gas two phase turbulent flow and heat transfer is further revealed.

The proper alkaline content was in favor of compressive strength. The chemically combined water of paste without activator decreases with the increase of fly ash content, the content of Ca2 decreases after 28d. The increase extent of chemically combined water of pastes with NaOH is higher than that of without activator, and the paste with Ca2 is the same. The XRD peak of Ca2 of paste without activator is high at early age, and the peak of mullite and quartz has less change along with age. When NaOH is added, the peak of quartz of fly ash has clear drop. The surfaces of fly ash activated has eroded trace at 7 d.

研究结果表明：适量碱的掺入对强度有利；未掺激发剂浆体的化学结合水量随着粉煤灰掺量的增加而减少，Ca2含量在28d后开始下降；掺NaOH浆体的结合水量随龄期增长的幅度比未掺激发剂的浆体的大，而掺Ca：试样变化较小；未掺激发剂的水泥－粉煤灰体系在早期Ca2的峰值较大，且粉煤灰中的莫来石和石英晶体的衍射峰随龄期变化不大；NaOH掺入后，28d时，粉煤灰中的石英晶体衍射峰明显下降；时于掺激发别的试样，在7d时粉煤灰颗粒表面已被腐蚀。

I lease a more advanced selection of dry ash ground equipment for deep processing of original ash to reach the national grade ò fly ash standards, improve the sales in the market, and achieved good social and economic benefits.

During extracting vacuum still bottom and hydrocyclone underflow of H-coal process,coal liquid could be clearly divided into deashed liquidproducts of ash yield less than 0.05% and ash-rich residue with ash yield greater than 60%.

在萃取氢-煤法减压蒸馏釜液或水力旋风分离器底流物时，这些重质物料可分离成灰分在0.05%以下的低灰液体产品和灰分达60%以上的富灰残渣。

The slump and the time of slump are tested through the method of slump test, and the properties of concrete are calculated and analyzed. The study denotes that for C20 grade concrete, the value of the shear yield stress σ0 and plastic viscosity η is the smallest when the fly ash contains 20% weight of Portland cement; for C60 strength grade concrete, the value of plastic viscosity is the smallest when fly ash contains 20% weight of Portland cement and the value of the shear yield stress σ0 is the smallest when fly ash contains 30% weight of Portland cement.

利用改良坍落度筒的实验方法对坍落度和坍落时间进行测试，并进行相应的计算与分析，实验结果表明：强度等级为C20的混凝土，粉煤灰掺量为20%时粘度和屈服应力值最低；强度等级为C60混凝土，粉煤灰掺量为20%时，其粘度最低，而屈服应力值在粉煤灰掺量为30%时最低。

The high level of Al(subscript 2)O(subscript 3) in the fly ash is yielded during the transformation and decomposition of kaolinite and boehmite in the feed coal at a high temperature, commonly between 950~1200℃ Very low level (1.9%) of quartz in all minerals of the coal has correspondingly elevated the Al2O3:SiO2 ratio of the fly ash up to 1.50, which is three times of common fly ash in China.

粉煤灰中高Al2O3含量来源于煤中丰富的高岭石和勃姆石矿物在电厂高温下的转化和分解产物；石英仅占煤中矿物组分的1.9%，也相应地提高了粉煤灰中的Al2O3/SiO2：质量比，使得这一比值达到1.50，是常见粉煤灰的3倍左右。
