Thermo-power plant boiler industry

在热电锅炉行业，公司主导产品为LGM/KE型高效能脉冲袋式除尘器，采用分箱式结构，实现离线检修，滤袋长度从6m\~10m，颗粒物排放稳定低于5mg/Nm³。

In the thermal power plant boiler industry, Kelin's leading product is the LGM/KE highefficiency pulse bag filter, which adopts a box type structure to achieve offline maintenance. The filter bag length ranges from 6m to 10m, and the particle emission is stable below 5mg/Nm³.

开发历程 Development process

公司早在上世纪80年代初就与北京劳保所合作探索在燃煤锅炉上使用袋式除尘器；

Kelin cooperated with Beijing Labor Protection Institute in the early 1980s to explore the use of bag filters on coal-fired boilers;

90年代末通过全球环境基金会（GEF）项目引进了美国燃煤工业锅炉用袋式除尘技术，1999年在75t/h燃煤锅炉示范项目中获得成功，以排放浓度低、滤袋寿命长、运行稳定等优势得到了全面推广应用

In the late 1990s, the bag filter technology for coal-fired industrial boilers in the United States was introduced through a Global Environment Facility (GEF) project. In 1999, it was successfully applied in a 75t/h coal-fired boiler demonstration project and widely promoted due to its advantages such as low emission concentration, long filter bag life, and stable operation;

2006年开发的电改袋和电袋组合技术在热电锅炉行业开始推广，并在300MW级的多个发电机组上成功应用，电袋除尘器获得环保部科技进步奖三等奖

The ESP revamping to bag and combination of ESP &bag technology developed in 2006 began to be promoted in the thermoelectric boiler industry and successfully applied to multiple 300MW power generation units. The combination of ESP & bag filter won the third prize of the Ministry of Environmental Protection's Science and Technology Progress Award;

2012年开发的10m 超长袋大脉冲除尘技术在350t/h水煤浆锅炉项目中首次成功应用，多台产品出口日本，2015年获得了中国机械工业科学技术奖三等奖

The 10m ultra long bag large pulse dust removal technology developed in 2012 was successfully applied for the first time in a 350t/h coal water slurry boiler project, and multiple products were exported to Japan. In 2015, it won the third prize of the China Machinery Industry Science and Technology Award

Biomass boiler bag filter

针对生物质锅炉烟气中既含有带火星的轻颗粒粉尘，又含有较粗颗粒的带泥沙粉尘的特点，公司针对开发了火星捕集及泥沙等粗颗粒一体化预分离技术、轻质粉尘旋流捕集技术、除尘器抗泥砂磨损结构设计，保证了袋式除尘器稳定运行。

In response to the characteristics of biomass boiler flue gas containing both light particle dust with sparks and coarse particle dust with sediment, the company has developed integrated pre separation technology for Mars capture and coarse particles such as sediment, light dust cyclone capture technology, and anti-mud sand abrasion structure design for dust collectors to ensure stable operation of bag filters.

电改袋/电袋组合除尘器通常用于对原有电除尘器提标改造，满足颗粒物低排放要求，电袋组合除尘器也可用于新建项目。相比分箱式结构，此类产品直通式结构对气流均布和结构优化设计提出了更严格的要求。

ESP revamping to bag filter / combination of ESP &bag filter is usually used for upgrading and retrofitting existing electric dust collectors to meet the requirements of low particulate matter emissions. Combination of ESP &bag filter can also be used for new construction projects. Compared with the boxtype structure, the straight through structure imposes stricter requirements on airflow distribution and structural optimization design.
