依据煤气身分来调解煤气星力手机捕鱼操纵的办法Adjust the method of operation of gas producer according to gas composition

   怎样依据煤气身分来调解煤气星力手机捕鱼操纵?

    纷歧定每个数据都作为调解操纵的根据,而是要择其随炉况变革大的次要煤气身分,依据这些次要身分来调解煤气星力手机捕鱼操纵。以烟煤为质料的煤气星力手机捕鱼煤气为例。煤气中氮气是剖析后的剩余量,以是本省意义不大,但可参考的是若氮气含量高了当前,那么可燃身分肯定降落。煤气中的氧气除特别状况下,普通在0.2%-0.4%左右,靠近或超越1%时阐明有烧穿或部分不气化景象。煤气的碳氢化合物普通在0.2-0.4%左右,变革不会大。煤气中的甲烷普通在1.8-2.2%左右,变革也不会大。

    剩余的便是CO,二氧化碳和氢气,这三个身分随炉况动摇而随之带来的变革也大。以是一样平常依据这三个身分来调解操纵。

    1、当呈现二氧化碳偏高,CO偏低,阐明该煤气星力手机捕鱼复原反响不完全、复原层太薄或煤层太薄,外表温度高,因而要得当加厚煤层(在料层高时,可得当添加出灰速率)。

    2、当二氧化碳偏高,CO偏低,氢气又偏高时,阐明饱和温度用的过高,致使于形成少量热量为水蒸气剖析吸取,此时应得当的降下饱和温度。

    3、当呈现氢气偏高时,应留意得当的降下饱和温度,并反省能否有漏水景象。

    4、当呈现氢气偏低,而二氧化碳与CO含量尚属于正常时,此时应得当进步饱和温度。

    5、当呈现二氧化碳过高,CO偏低,而氢气又偏低时,此时也阐明料层过薄,两段式煤气星力手机捕鱼,或有烧穿景象,此时需加厚煤层,低落炉出温度。

    煤气身分剖析只是调解操纵的根据之一,以是调解时不克不及光凭煤气身分剖析的数据,同时要联合仪表指示,测钎剖析、炉渣状况、综合停止思索。

    煤气星力手机捕鱼空层高度是指从炉内料层上外表到炉顶之间,即加料和反响天生物在炉内停顿的空间。在操纵进程中,每每无视空层的作用,加料和出灰的速率控制恰当,形成空层时高时低。

    煤气星力手机捕鱼消费厂家发明空层高度减小,使下煤不平均,两头下煤多,周围下煤少,构成两头火层降落,周围气体流速放慢,两头气化弱,形成偏炉、穿火等不良工况,煤气质量降落,炉况难以控制。

    空层高渡过大,煤层必定减薄。由于炉内温度达450—520摄氏度,块煤入煤气星力手机捕鱼时,降落工夫延伸,破裂成小颗粒或粉末的比例添加,对气化倒霉。而且由于煤层相应减薄,影响煤炭枯燥、干馏及气化的完全停止,使煤气质量降落。

    因而,关于空层高度的控制具有相称紧张的意义。控制空层高度的办法是经过延续而小量加煤,无级变速出灰安装并低速运转来完成。同时,要勤测钎,只需发明空层增加,就要加大出灰速率。

    空层高度普通控制在2.25—2.60m之间。关于煤气星力手机捕鱼这一特别的煤炭转化设置装备摆设,为了进步转化率,除接纳须要的技术步伐外,还必需接纳综合办理的手腕,才干从真正意义上到达进步煤气质量的目标。

    综合办理包罗消费质量办理、平安办理及信息办理等。企业应增强动力运转办理,美满消费稽核制度,激起职工注重煤气质量的认识和节能积极性,使煤气炉配件企业消费能耗逐渐低落,进步企业本身的经济效益。

How to adjust gas generator operation according to gas composition?

It is not necessary to use each data as the basis of adjustment operation, but to choose the main gas components which vary greatly with the furnace condition, and adjust the gas generator operation according to these main components.Taking bituminous coal as raw material gas producer gas as an example.Nitrogen in the gas is the residual amount after analysis, so the significance of this province is not big, but the reference is if the nitrogen content is high, then the combustible composition must decline.Except under special circumstances, the oxygen in the gas is generally about 0.2%-0.4%, close to or more than 1% when there is a burning through or local gasification phenomenon.The hydrocarbon of gas is in commonly 0.2-0.4% left and right sides, change won't big.Methane in gas is generally about 1.8-2.2%, the change is not big.

The remaining components are CO, carbon dioxide and hydrogen, which vary greatly with the furnace's state.So adjust the daily operation according to these three components.

1. When the carbon dioxide is on the high side and the CO is on the low side, it indicates that the coal gas has an incomplete reduction reaction in the furnace, the reduction layer is too thin or the coal seam is too thin, and the surface temperature is high. Therefore, the coal seam should be appropriately thickened (when the material is layer high, the ash discharge rate can be appropriately increased).

2. When carbon dioxide is on the high side, CO is on the low side, and hydrogen is on the high side, it indicates that the saturation temperature is too high, which results in a large amount of heat being decomposed and absorbed by water vapor. At this time, the saturation temperature should be lowered appropriately.

3. When hydrogen gas is on the high side, it should be noted to properly lower the saturation temperature and check whether there is water leakage.

4. When hydrogen is low and the content of carbon dioxide and CO is normal, the saturation temperature should be appropriately raised.

5. When the carbon dioxide is too high, the CO is too low, and the hydrogen is too low, it also shows that the material layer is too thin, the two-stage coal gas furnace occurs, or there is a burning through phenomenon, at this time need to thicken the coal seam, reduce the furnace temperature.

Gas component analysis is only one of the bases of adjustment operation, so the adjustment can not only rely on the gas component analysis data, at the same time to combine with the instrument indication, measuring the brazing analysis, slag situation, comprehensive consideration.

The empty layer height of the gas producer refers to the space between the upper surface of the material layer in the furnace and the top of the furnace, that is, the space where the charging and reaction products stay in the furnace.In the process of operation, the effect of empty layer is often ignored, and the speed of feeding and ash discharge is not properly controlled, resulting in high and low empty layer.

The producer of coal gas generator found that the empty layer height decreased, making the coal uneven, more coal in the middle, less coal around, forming the middle layer of fire down, gas velocity around the speed up, the middle gasification is weak, resulting in partial furnace, fire penetration and other bad working conditions, gas quality decline, difficult to control the furnace.

Empty layer passes big, coal seam decreases necessarily thin.As the temperature in the furnace reaches 450-520 degrees Celsius, when the coal into the gas furnace, the falling time is prolonged, broken into small particles or powder proportion increases, to the gasification adverse.And due to the corresponding thinning of coal seam, the coal drying, dry distillation and gasification of the complete process, so that the quality of coal gas.

Therefore, it is very important to control the height of empty layer.The method to control the height of the empty layer is through continuous and small amount of coal, continuously variable speed ash device and low speed operation to achieve.At the same time, to frequently test the bit, as long as the empty layer is found to reduce, it is necessary to increase the speed of ash.

The height of empty layer is generally controlled between 2.25 and 2.60m.In order to improve the conversion rate of the special coal conversion equipment, in addition to taking the necessary technical measures, we must also take the means of comprehensive management, in order to improve the quality of coal gas from the real sense.

Comprehensive management includes production quality management, safety management and information management.Enterprises should strengthen the management of energy operation, improve the production assessment system, stimulate the awareness of workers to pay attention to the quality of gas and enthusiasm for energy conservation, so that gas furnace parts enterprises gradually reduce production energy consumption, improve their own economic benefits.
