焦炉煤气发电机组做为焦化使用的特点

来源:http://www.huannengpower.com   发布于:2019-01-29

焦炉煤气是焦化工业的首要副产品之一,每炼一吨焦炭会产出300-350m3左右的焦炉煤气,焦炉煤气约40%-50%用于回炉燃烧,其余剩余煤气有必要运用专门回收设备进行回收运用,否则只能燃烧排放大气。一些小的企业,由于炼焦发作的焦炉煤气量较少,出资甲醇、化肥等其他项目或许还达不到规划,成本优势不明显,因此用于焦炉煤气发电是一种出资小、见效快的一种有效途径。

Coke oven gas is one of the primary by-products of the coking industry. Each ton of coke produced about 300-350m3 of coke oven gas. About 40-50% of coke oven gas is used for back-burning. It is necessary to use special recovery equipment to recover the remaining gas, otherwise it can only burn and discharge the atmosphere. Some small enterprises, due to the small amount of coke oven gas in coke oven, investing in methanol, fertilizer and other projects may not reach the planning, the cost advantage is not obvious, so the use of coke oven gas for power generation is an effective way with small investment and quick effect.

2. Functional Characteristics of Internal Combustion Coke Oven Gas Generator Unit

焦炉煤气内燃机发电机组的作业原理与轿车发动机作业原理类似,需要用火花塞燃烧,由于内燃机汽缸内作业温度抵达14000?使其功率大大超过了蒸汽轮机和燃气轮机,发电功率抵达35%以上。其特征为:

The working principle of coke oven gas internal combustion engine generator set is similar to that of car engine. It needs to be burned with spark plug. Because the working temperature in the cylinder of internal combustion engine reaches 14000, its power greatly exceeds that of steam turbine and gas turbine, and its power generation reaches more than 35%. Its characteristics are as follows:

2.1结构紧凑,体积小占地少。

2.1 Compact structure, small size and small occupation of land.

2.2热功率高,相比较蒸汽轮机和燃气轮机高10%以上。

2.2 High thermal power, 10% higher than steam and gas turbines.

2.3操作简洁,起动方便。

2.3 The operation is simple and easy to start.

2.4规划可选择规模较宽,几台或十几台并机均可。

2.4 Planning can choose a wider scale, several or more machines can be combined.

2.5由于工艺简略,出资较少可进行主动化控制。

2.5 Because of the simplicity of the process, less investment can be made to carry out active control.

网停电时发电机所发电力反送入市电电网构成事故。

3.2 A set of equipment reverse power maintenance module at the low-voltage main switch of the main distribution room can prevent the power generated by the generator from being sent back to the municipal power grid when the power outage occurs.

3.3当外网停电时,低压总开关通过逆功率模块控制断路器跳开,发电机变成孤网工作,确保风机、循环氨水泵等首要设备不断电而正常工作;可避免焦炉因停风机而发作的烟火污染,如功率足够大也可确保焦炉的正常生产。

3.3 When the power outage occurs in the external network, the low-voltage main switch controls the breaker to jump off through the inverse power module, and the generator turns into an isolated network to ensure that the primary equipment such as fans and circulating ammonia water pumps are continuously powered up and working normally. It can avoid the pyrotechnic pollution caused by the blower outage in the coke oven, and ensure the normal production of the coke oven if the power is large enough.

3.4当外网再次供电时,可通过总开关处同期设备再次并网继续工作。

3.4 When the external network is powered again, it can be connected to the grid again through the same period of equipment at the main switch.

3.5发电机组可通过程控机软件实时监控发电机组的各种温度、压力、电压、电流等参数和主动调理煤气、冷却水等流量,确保发电机组的正常工作

3.5 The parameters of temperature, pressure, voltage and current and the flow of gas and cooling water can be monitored in real time by the program-controlled computer software to ensure the normal operation of the generating unit.

4.定论

4. conclusion

关于焦化企业来讲,任何时刻停电都将构成巨大的丢掉,一旦停电,焦炉上升管因压力过高,焦炉荒煤气逸出,均需翻开放散管放散而构成焦炉炉顶浓烟滚滚,环保方面是不允许的;别的由于焦炉炉体内荒煤气无法导出,压力过高会构成内部串漏对炉体的损害也很大,循环氨水间断循环也会给煤气冷却和焦油导出构成极大困难;由此可见,采用双回路不间断供电对企业来讲是至关重要的。

As far as coking enterprises are concerned, blackouts at any time will constitute a huge loss. Once blackouts occur, the riser of coke oven will cause excessive pressure and the waste gas of coke oven will escape. It is necessary to turn over and open the loose pipe to dissipate the heavy smoke on the top of coke oven, which is not allowed in environmental protection. Otherwise, because the waste gas in the coke oven can not be exported, excessive pressure will cause serious damage to the furnace. Intermittent circulation of circulating ammonia water also poses great difficulties for gas cooling and tar export. Thus, it is very important for enterprises to adopt double-loop uninterrupted power supply.

运用焦炉充裕煤气发电,一能处理焦化企业供电确保问题;二能在节能减排的一起还可以发明经济效益,较好的处理了煤气浪费、污染环境和外购电能的对立。而且焦炉煤气发电技能老练,出资少见效快,是中小型焦化在运用较少资金能够取得许多方面收益的一种有效途径,也对缓解我国动力严重具有重要意义。

Utilizing coke oven gas to generate electricity can not only deal with the problem of ensuring power supply in coking enterprises, but also create economic benefits with energy saving and emission reduction, which can better deal with the opposition of gas waste, environmental pollution and purchased electric energy. Moreover, the sophisticated coke oven gas power generation skills, less investment and quick results, is an effective way for small and medium-sized coking in the use of less funds to achieve many benefits, but also to ease the power of our country is of great significance.
