1、投资费用低，脱硫产物呈干态，并与飞灰相混。
1. The investment cost is low, the desulfurization products are dry and mixed with fly ash.
2、无需安装除雾器及烟气再热器，设备不易腐蚀，不易发生结垢及阻塞。
2. There is no need to install mist eliminator and flue gas reheater. The equipment is not easy to corrode and scale and block.
炉内喷钙脱硫是目前最常用的干法脱硫工艺。该系统工艺简单，脱硫费用低，用石灰石和消石灰吸收剂，烟气脱硫率可达60%以上。
