Particle Probes

The prefer­ably reg­u­lar use of par­ti­cle probes is suit­able for mon­i­tor­ing fuel changes and process adjust­ments. These probes sup­port the plant oper­a­tor in recog­nis­ing lee­way in the boil­er design and in adjust­ing the mode of oper­a­tion and the fuel in such a way that cor­ro­sion and foul­ing are reduced.

For this, the grid probe is insert­ed into the flue gas flow for a few sec­onds. The flue gas is sucked through a microme­tre-fine grid and the salts and ash­es are deposit­ed on the sur­face. We analyse these deposits and can use them to pro­vide infor­ma­tion on cor­ro­sion and foul­ing tendencies.

Fur­ther infor­ma­tion on the grid probe can be found in our flyer.

We insert a sam­pling probe into the flue gas at the end of the boil­er for about 30 to 60 min­utes to deter­mine the ash-salt pro­por­tion (ASP). The analy­sis of the flue gas par­ti­cles with regard to their chem­i­cal com­po­si­tion pro­vides infor­ma­tion on the total dust load and the load of indi­vid­ual ele­ments, which can then be used to opti­mise oper­a­tion with regard to cor­ro­sion and fouling.

Fur­ther infor­ma­tion on the ASP can be found in our flyer.
