锻烧无烟煤应用
无烟煤块煤主要应用是化肥(氮肥、合成氨)、陶瓷、制造锻造等行业;无烟粉煤主要应用在冶金行业用于高炉喷吹(高炉喷吹用煤主要包括无烟煤、贫煤、瘦煤和气煤)。
锻烧无烟煤在分解炉的使用
分解炉的作用是在固相悬浮于热气体的条件下完成碳酸盐的分解吸热反应。
CaCO3=CaO+CO2↑
在所提供的热量不能使生料完全分解的情况下,分解过程可按CO2的分压达到某一平衡状态考虑。一般来说分解炉的平衡状态温度处于850~900℃范围。分解炉内的温度分布与下列因素有关。
1)燃烧成气相视的放热速率。
2)由气相传给固体生料粉的传热速率。
3)生料颗粒分解时的吸热速率。
无烟煤注意事项
与使用烟煤相比,由于无烟煤挥发份较低,因此需要一个相对较大的分解炉,以期获得相同的生料分解率和相同的煤粉燃烬程度,或者要求一个较高的操作温度,或者将无烟煤磨得更细一些。
当三次风温较低时,无烟煤挥发出来的气体往往不能产生足够的热量使温度升高。,所以将煤粉直接喂入温度范围通常在1000~1200℃的上升烟道废气中可确保煤粉燃烧。
另外需要提出的是燃烧速度和燃烬时间还取决于烟气中的O2含量,用较高的空气过剩系数操作分解炉时刻缩短燃烬时间,但通常增大空气过剩系数的做法将会增加通过预热器的气体流量。为此将造成较大的压差和较高的废气温度,从而使窑主排风机的负荷增大,整个窑系统的单位热耗也将有所增加。
改变生料喂入方式是相当重要的,采用无烟煤操作时,无烟煤与生料粉的混合最好能有适当的滞后时间,以保证无烟煤的点燃,因此对喂入分解炉的生料需要进行分级控制,以便使分解炉底部形成一个相对高温区。判断生料在分解炉内是否达到预期的效果,最好的办法是检测入窑生料分解率,如果入窑生料分解率达到了预期效果,说明无烟煤在分解炉内的燃烧是合适的。
无烟煤在窑头燃烧器的使用
新型干法水泥生产线装备有现代化的燃烧器,现代化的燃烧器配备有适当的火焰调节装置,可以使无烟煤没有任何问题地在窑头进行燃烧。 燃烧器的作用不仅仅是输送和分布煤粉,更主要的是保持火焰的理想长度和合适的气体流场。火焰的长度对于新型干法窑来讲十分重要,火焰如果过短,煤的潜热只能在较小体积内释放出来,火焰的温度就会在局部变得很高,相反,如果火焰长度加长,温度就会下降。火焰的长度主要靠燃烧器的推动力进行控制。
燃烧器的推动力=一次空气(kg/s)×燃烧器尖端风速(m/s)
当燃烧器推动力加大时火焰长度缩短。
原煤的种类对火焰的长度并不十分重要,只要求单个煤粒子的燃烬时间小于其在火焰中的停留时间即可。
如果目标是让无烟煤与烟煤保持相同的火焰长度,那么就必须对煤粉的燃烬时间进行补偿。简单的做法就是将无烟煤磨得更细一些。
高温二次风将会快速加热进入燃烧器的煤粉的挥发分快速排出,煤粉一经离开燃烧器端部,焦炭粒子就会点燃,因此冷却机的使用效果将对无烟煤的使用产生一定影响。
在回转窑窑头燃烧器上使用无烟煤需要保证如下条件:
1)煤粉能达到足够的符合要求的细度,以保证燃烧和火焰形成。
2)控制可靠稳定的煤粉喂料。
3)燃烧器的一次分必须具有足够的推动力并可调节。
4)燃烧器必须能够在燃烧带产生有充分内部循环空气的火焰,以保证无烟煤尽快点燃。
5)在启动冷窑或窑况不正常时利用烟煤或燃油辅助燃烧。

Forging burn anthracite products is introduced
Forging burn anthracite is commonly known as red stone coal or coal. Is the largest degree of coalification of coal. Volatile anthracite fixed carbon content, high yield, low density, high hardness, high flash point, do not smoke during burning. Black solid, with metallic luster. As fat friction does not stain, fracture into conchoidal, burns, short flame and smoke less. No coking. General carbon content above 90%, the volatile matter below 10%. No glue layer thickness. Calorific value of about 8000-8500 kcal/kg. The volatile matter content of very large sometimes referred to as half anthracite coal; Small called high anthracite.
Forging burn anthracite characteristics
Anthracite as the degree of coalification coal, the most the most carbon content, ash content, moisture content is less, the calorific value is very high, up to 25000 ~ 32500 kj/kg, volatile release temperature is higher, the coke without adhesion, ignition and burnout are more difficult, smokeless burning, the flame of the blue. Coal samples under prescribed conditions the air heating, coal thermal decomposition of organic matter in the part of the smaller molecular weight liquid (state) at this time for steam and gas products, these products are called volatiles. Points to the quality of volatile matter of coal sample become volatile yield or volatile for short. To dry ash-free basis for the analysis basis, known as anthracite coal volatile matter less than 10%. Volatile is more than 6.5% less than 6.5% of the anthracite is called used no. 3. 01 anthracite anthracite for old age; No. 02 anthracite for typical used; 03 anthracite anthracite for the young.
Anthracite coal reserves in China
China anthracite predicted reserves of 474 billion tons, accounting for 10% of the total coal resources across the country, annual output of 200 million tons. Shanxi Province accounted for 32%, 18%, in henan province guizhou province accounted for 11%. Six major anthracite base in China: Beijing Beijing coal group, jincheng coal group, jiaozuo coal group, the city always in henan mine, shenhua ningxia coal group, yangquan coal group.
Forging burn anthracite applications
Anthracite lump coal is the main application of chemical fertilizer (nitrogen, ammonia), ceramics, the manufacturing of forging; Anthracite pulverized coal is mainly used in metallurgical industry for blast furnace injection (injection in the blast furnace coal mainly includes anthracite, lean coal, lean coal and gas coal). The use of forging burn anthracite coal in the calciner
The function of decomposing furnace is under the condition of solid phase suspended in hot gas carbonate decomposition endothermic reaction. CaCO3 = write CaO + CO2
Provided the quantity of heat cannot make raw materials under the condition of complete decomposition, decomposition process according to the partial pressure of CO2 reaches an equilibrium state. In general balance temperature of decomposing furnace is in the range of 850 ~ 900℃. Decomposition temperature distribution inside the furnace is related to the following factors. 1) the combustion heat release rate of gas each other. 2) by passing from gas to solid raw powder, heat transfer rate. 3) decomposition heat absorption rate of the raw material particles. Anthracite coal
Compared with using bituminous coal, due to the low anthracite volatile flux, so need a decomposing furnace is relatively large, in order to obtain the same raw material decomposition rate and pulverized coal combustion degree, state of the same or require a higher operating temperature, or some will be more fine anthracite coal mill. When three blast temperature is low, anthracite volatile out often cannot generate enough heat to make gas temperature. The pulverized coal directly feeding temperature range, often rising in 1000 ~ 1200℃to ensure pulverized coal combustion flue gas. Also need to come up with is burning rate and combustion time also depends on the state of O2 content in flue gas, with a high excess air coefficient decomposition furnace operation time shorten the combustion time state, but will usually increase the excess air coefficient increase the gas flow through the preheater. This will cause large pressure difference and high exhaust temperature, thus make kiln-owners' exhaust fan load increases, the unit heat consumption of the whole kiln system will also increase. Change the raw meal feeding way is quite important, use anthracite, anthracite mixed with raw powder of it is best to have appropriate lag time, to ensure the lighting of anthracite, so to feed raw materials need to be graded control of decomposing furnace, so that the decomposition at the bottom of the furnace to form a relatively high temperature. Whether raw materials on the decomposition furnace, achieve the desired effect, is the best way to test the soil of decomposition rate, if the meal decomposition rate of the desired effect, in that anthracite combustion inside the furnace is appropriate.
The use of anthracite coal in a kiln burner head
NSP cement production line is equipped with modern burner, modernization of the burner equipped with proper flame adjustment device, can make the anthracite coal combustion without any problems at the kiln head. Pulverized coal burner role is not only a transmission and distribution, more major is to keep the flame of the ideal length, and proper gas flow field. Flame is very important for NSP kiln, the length of the flame if too short, the latent heat released only in a small volume of coal, the flame temperature will become very high in local, on the contrary, if the flame length is longer, the temperature will drop. Mainly by the burner flame length of thrust control. Burner boost air (kg/s) = a * burner tip wind speed (m/s)
When the burner impetus to increase flame length shorter. Crude coal type on the flame length is not very important, only requires a single coal particle combustion time is less than the state in the flame residence time can be. If the goal is to let the flame of anthracite and bituminous coal to keep the same length, then it must be for pulverized coal combustion time for state compensation. It is simple to anthracite more fine grinding. High temperature secondary air will rapid heating into pulverized coal burner in the volatile rapid eduction, pulverized coal is left burner ends, coke particles will be light, so the use effect of the cooling machine will affected the use of anthracite coal. Using anthracite on rotary kiln burner head need to make sure that the following conditions:
1) pulverized coal fineness can reach enough to meet the requirements, to ensure that the combustion and flame. 2) reliable and steady control of pulverized coal feeding. 3) burner a points must have sufficient driving force and adjustable. 4) burner must be able to have sufficient internal circulating air in combustion zone of the flame, and to ensure that the anthracite as soon as possible. 5) in the abnormal startup cold kiln or conditions when using bituminous coal or fuel oil auxiliary combustion.
