我公司承建的山東高密垃圾焚燒發(fā)電2x400t/d循環(huán)流化床鍋爐煙氣凈化工程于2017年11月9日完成整體竣工驗收。
Shandong Gaomi Waste Incineration Power Generation 2x400t/d Circulating Fluidized Bed Boiler we contracted to build has completed its overall construction and acceptance check on November 9, 2O17.
該項目于2016年11月施工建設，2017年1月30日投入運行，同年8月31日整體竣工調試驗收結束。該項目為我公司EPC項目，采用靜電除塵器+半干法SDA工藝（旋轉噴霧半干法）+布袋除塵器+活性炭吸附+干粉噴射+飛灰穩(wěn)定化處理工藝。
The project was started its construction in November, 2016 and was put into operation on January 30, 2017. The overall construction & debugging work and acceptance check was completed on August 31st of the same year. It is a EPC project of our company, using Electrostatic Cleaner + Semi-dry SDA Process (Rotary Spray Semi-dry Method) +Baghouse Filter, Activated Carbon Absorption+ Dry Powder Jet, Fly Ash Stabilization Treatment Processes.
該工藝針對流化床垃圾爐灰量高、排煙溫度低、SOx波動不穩(wěn)定、灰分差異導致的輸送方式不同等特性進行了針對性地工藝調整。早期的流化床垃圾爐，由于煤的摻燒比較高，因此煙氣燃燒工況較為平穩(wěn)。隨著國家出臺了發(fā)電量補貼上限為噸垃圾280度的規(guī)定以及煤價上揚帶來的成本上升，流化床垃圾爐燃料中煤的摻燒比逐年下降，隨之帶來的燃燒工況出現(xiàn)了較大的改變。
為此，華星東方工程師與錦江集團技術人員等在實踐中不斷摸索，陸續(xù)在天津晨興一期，二期，甘肅張掖等項目上進行了工藝改進。
This process is designed to offer a targeted process adjustment for the characteristics of fluidized bed including high ash content, low temperature of flue gas discharge, SOx fluctuation instability, ash composition difference which requires for different transport modes. For the early stage of the fluidized bed waste incinerators, the combustion condition of flue gas is relatively stable due to the high blending burning ratio of coal. Due to the provision the nation has published on the subsidy top-limit for power generation should be 280 degrees per ton of garbage and the uprising cost caused by the rising coal price, the blending burning ratio of coal in the fuels of fluidized bed waste incinerator is decreasing year by year, consequently the combustion condition has a big change.
For this reason, the HXEP engineers, together with the technical staff of Jinjiang Group, are continuously exploring in practice and achieved process improvement in the following projects such as Tianjin Chenxing First Stage & Second Stage and Gansu Zhangye, etc.

公司工程技術人通過此次山東高密項目的調試，利用積累的工程經驗，進行了多次技術優(yōu)化調整，最終找到了一條適合國內現(xiàn)有流化床垃圾爐運行的先進煙氣凈化工藝路線，很好地適應了流化床垃圾爐的持續(xù)運行和穩(wěn)定達標排放。
Through the debugging work for the Shandong Gaomi Project, our engineers and technicians took advantage of the accumulated engineering experiences to make a plenty of technical optimization adjustments so that they finally found out an advanced FGC process route which is suitable for the existing operation status of the domestic fluidized bed incinerators. It is well adapted to the continuous operation of fluidized bed waste incinerator and reaches the stable up-to standard emission requirement.

隨著流化床垃圾焚燒技術的不斷發(fā)展，公司通過不斷引進吸收歐洲先進技術工藝，繼天津，張掖，高密之后，陸續(xù)在山東臨淄以及河北石家莊等項目上持續(xù)進行工藝改進，不斷調整和摸索適合中國流化床垃圾爐工況的煙氣凈化技術。
With the continuous development of waste incineration technology in fluidized bed , our company constantly introduced a lot of advanced process technologies from Europe to conduct process improvement in the first group of projects such as Tianjing, Zhangye and Gaomi, then further process improvement was made in projects of Shangdong Linzi as well as Hebei Shijiazhuang. In this process ,we have been constantly adjusting and probing for a FGC technology which is suitable for the combustion condition of Chinese fluidized bed waste incinerator.
經過驗收，兩套煙氣凈化裝置運行工況良好，煙氣處理各項指標均低于國標18485-2014標準，同時低于歐盟2000標準。
After having passed the acceptance check, the two FGC lines still have quite good running conditions. Each index of flue gas treatment is lower than the international standard 18485-2014 .It is also lower than the European Standard 2000 at the same time.
