The FGC system is mainly used to remove particles, acid substances, heavy metals, and other pollutants at the outlet of the waste heat boiler, meeting the emission requirements of the plant. The FGC system adopted the combined process of "SNCR in-furnace denitration with urea + semi dry method with Ca(OH)2 + dry method with Ca(OH)2 + activated carbon injection adsorption + dry method with high-efficiency turbulent circulation deacidification + bag filter with mass-returning + SCR reserved +fly ash conveying, storage, and stabilization+ ID fan”. The flue gas online analyzer is set at the inlet of the semi dry reaction tower and the outlet of the semi dry reaction tower . CEMS is set at the chimney inlet. The automatic control of reagent dosing is realized. It is an EP project of Huaxing.

随着中国点火设备逐步走向国际市场
，，，伟德国际官网东方在参加外洋国际互换和竞标活动时
，，，感触到近几年国际主流烟气工艺的趋向正在从半干法、、湿法往高效干法转变。出格是伟德国际官网东方协助国内总包方走出去时遭逢欧美企业较低的锅炉排烟温度而获得的较高锅炉效能
，，，越来越成为中国设备竞标国际项主张短板。

2016年起
，，，为了相识和把握将来烟气工艺发展的最新走向
，，，伟德国际官网东方技术团队陆续走访了欧洲部门点火厂并与欧洲同业发展了接触与互换
，，，就该工艺的引进进行了接洽。

As China's incineration equipment is gradually moving towards the international market, when participating in international exchanges and bidding activities, Huaxing experienced that the mainstream of flue gas cleaning technology was recently changing from semi-dry / wet method to efficient dry method. In particular, when Huaxing assisted the domestic enterprises to go abroad, the higher boiler efficiency obtained by European and American enterprises due to the lower boiler exhaust gas temperature has increasingly become a weak point for Chinese equipment to bid for international projects.

Since 2016, in order to understand and master the latest trend of future FGC process, the technical team of Huaxing East has successively visited some incineration plants in Europe, carried out basic contacts and communications with European counterparts, and contacted the introduction of the new dry-process.

2017年底
，，，伟德国际官网东方与欧洲同业初次携手签署了北京高安屯医废项目
，，，率先确立了使用该“高效紊流循环脱酸干法工艺”。

At the end of 2017, Huaxing and its European partner jointly signed the Beijing Gao'antun Medical Waste Project for the first time, taking the lead in establishing the use of the dry-process of "Efficient Turbulent Circulation Deacidification".

2018年伟德国际官网东方顺利与欧洲同业携手实现了泰国工业固废项目
，，，成立了第一次合作。

In 2018, Huaxing successfully completed the industrial solid waste project in Thailand with its European partner, established the first cooperation.

2019年起
，，，伟德国际官网东方携手欧洲同业与北控集团北发建设一起将该工艺利用于常德三期生涯垃圾点火项目
，，，并于2020年起头执行
，，，2021年7月接入烟气
，，，2022岁首实现72小时验收。截止发稿为止
，，，该系统已安稳运行1年3个月。

Since 2019, Huaxing East & its European partner and Beifa Construction of Beijing Enterprises Group have applied this process to the Changde Phase III WTE plant. The new dry-process was implemented in 2020. The flue gas was connected in July 2021, and the 72 hours acceptance was completed in early 2022. As of the date of publication, the system has been running smoothly for 1 year and 3 months.

与常德二期传统的SDA工艺相比
，，，其陆续周期运行指标根基靠近
，，，但石灰亏损量低至5kg/t垃圾
，，，并且省去了制浆系统的投资和运行守护能耗。

Compared with the traditional SDA process in Changde Phase II, its continuous cycle operation index is close, but the lime consumption is as low as 5 kg/ton MSW. The investment in the slurry preparation system and the energy consumption for operation and maintenance are saved.

该项主张意思：

1、、解决了物料循环系统在中国烟气含湿率高的炉排炉利用工况下的持久安稳可控运行。自我国引入NID及Turbosorp以来

2、、为小苏打工艺引入
，，，通过物料循环从而削减物料亏损
，，，将SCR往上游移动和外置省煤器+二级活性炭干法和布袋工艺
，，，削减了蒸汽亏损。为超低排放从湿法转向双布袋干法工艺启发了路线。

3、、为原有SDA半干法工艺

The significance of the technology:

1. It solved the long-term stable and controllable operation of the material circulation under the condition of high-moisture grate furnace in China. Since the introduction of NID and Turboprop in China, except for a few grate furnace and most fluidized beds, there are rarely successful applications in China. Huaxing has participated in the SDA technical transformation of the circulating dry process in Cangzhou, Baoding, Shijiazhuang, etc. System operation was unstable in Haikou Phase I, Xiamen. The moisture content in flue gas and fly ash led to the instability of the circulation, which led to the failure of bed formation and the failure of system operation.

2. Sodium bicarbonate is introduced to reduce material consumption through material circulation. SCR is moved upstream and external economizer + two-stage activated carbon dry and bag process are installed to reduce steam consumption. It opens up a way for ultra-low emission from wet process to double-bag dry process.

3. It provides a solution for the original SDA semi-dry process to further achieve ultra-low emissions by adding a dry process under the condition of limited site.

4. By improving the control of SDA semi-dry flue gas exhaust temperature, adding sodium bicarbonate circulation combined with MHI's formula of denitration bag and its unique low-temperature regeneration, it is possible for the ultra-low emission transformation of the old incineration plant with extremely tight site.
