煅灰

The muffle kiln was also used in the experiment of calcining of MSWI fly ash. This study investigated the migration characteristics of 4 heavy metals in the process of calcining and established vaporescence kinetics models of heavy metals.

其次，采用高温箱式电炉对垃圾焚烧飞灰进行煅烧实验，对高温煅烧过程中4种重金属(Cd、Cu、Cr和Zn)挥发动力学展开研究，建立煅烧过程每种重金属挥发反应动力学模型。

The chemical activating mechanism of UA is that CG can stimulate pozzolanicity more effective than gypsum because of higher solubility and looser crystal structure; but CG has poor property on retardation setting, and this shortage can be solved by mixing with gypsum; CS can offer alkali activity, which can depolymerize silica and aluminum glass, and benefit for other activity methods and overcome the disadvantage of HF on setting time; Sodium sulfate improves early strength greatly but loses the final strength. NF can improve both early and final strengths.

联合激发技术的化学激发机理是，煅烧石膏溶解度高及晶体结构松弛，比天然石膏的活性激发效率高，但降低石膏的缓凝作用，与天然石膏混合既可提高活性又能保持缓凝作用；干法电石渣提供碱激发，促进高钙灰中硅、铝玻璃体解聚，并克服高钙灰对凝结时间的不利影响；硫酸钠虽然早强作用明显，但使后期强度倒缩，NF使各龄期活性都得到提高；磨细的物理激发使高钙灰大颗粒中的CaO和富集碳组分被磨细、分散，活性增加而危害性降低。

The fields of application of calcined FGD gypsum were gypsum wallboard,building plasters,self-leveling floor plaster,etc;The fields of application of uncalcined FGD-gypsum were cement, agricultural soil amendment, etc.

经煅烧的脱硫石膏的应用领域主要有：石膏墙板、建筑灰泥、自流平地板灰泥等；未经煅烧的脱硫石膏的应用领域主要有：水泥、农业土壤改良等。

The invention provides a sulfur oriented adsorption control method for calcining active lime in a rotary kiln comprising the following steps: the rotary kiln calcines the massive limestone using the mixture of the coal fines and active lime fine silts as fuels, the sulfur in the flue gas is adsorbed using the sulfur adsorption and desulphurizing ability of the active lime fine silts, meanwhile the sulfur-adsorbed kiln dust is separated from the calcined active lime by means of screening to get low sulfur-content active lime.

本发明提供的回转窑煅烧活性石灰中的硫定向吸附控制方法，具体是：回转窑以煤粉与活性石灰微细粉粒的混合物为燃料，在对块状石灰石煅烧时，利用活性石灰微细颗粒所具有的硫吸附与脱硫能力对烟气中的硫进行吸附，同时通过筛分将吸附了硫的窑灰与煅烧过的活性石灰分离，而得到低硫含量的活性石灰。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
