– a unique chance to record and eval­u­ate inter­ac­tions in the run­ning process

Work­ing close to real­i­ty instead of in a lab­o­ra­to­ry envi­ron­ment – this is our way to demon­strate the per­for­mance char­ac­ter­is­tics of mate­ri­als in the envi­ron­ment of chem­i­cal, ther­mal and mechan­i­cal inter­ac­tions – much more clear­ly than it would be pos­si­ble through lab­o­ra­to­ry tests on the test bench.

Our prac­ti­cal expe­ri­ence with cor­ro­sion and func­tion­al fail­ure in steam gen­er­a­tors or in flue gas clean­ing shows that the envi­ron­ment there can be high­ly vari­able and unsteady. This makes it dif­fi­cult to pre­dict how the mate­r­i­al in ques­tion will actu­al­ly behave. Any test that is not based on ‘real’ envi­ron­men­tal con­di­tions thus offers only and inad­e­quate basis for a decision.

Since 2006, we are devel­op­ing and build­ing our own patent­ed CheMin probe and tem­per­a­ture sen­sor tech­nol­o­gy, which we flex­i­bly adapt to the pre­cise task and the place of use.

This includes the Tem­per­a­ture-Range Probe (TRP), which is designed as a tube probe for use in super­heaters and as a tube wall probe for use in evap­o­ra­tors. The TRP is suit­able for var­i­ous mate­r­i­al, cor­ro­sion and coat­ing investigations.

The CheMin tem­per­a­ture sen­sor sys­tem plays an impor­tant role in process opti­mi­sa­tion in steam gen­er­a­tors. It can be used to record the heat load or heat absorp­tion of pipes and oth­er com­po­nents, so that suit­able mea­sures can be tak­en to achieve a more even and thus gen­tler load.

The CheMin range of probes also includes par­ti­cle probes, such as the grid probe, which is insert­ed into the flue gas flow for only a few sec­onds. The deposit­ed salts and ash pro­vide infor­ma­tion on cor­ro­sion and foul­ing behav­iour. A cor­re­spond­ing par­ti­cle probe is also avail­able to deter­mine the ash-salt pro­por­tion (ASP).

A high­light among the fam­i­ly of CheMin probes is our air-cooled mobile high-tem­per­a­ture cam­era probe, which can be used at short notice and in a tar­get­ed man­ner at a wide vari­ety of posi­tions along the flue gas path. It gath­ers opti­cal infor­ma­tion (both mov­ing and still images) which can reveal opti­mi­sa­tion poten­tial in many ways.

Our lat­est devel­ope­ment is the sul­pha­tion probe. It is suit­ed to deter­mine the SO₃ con­tents of the flue gas at var­i­ous loca­tions in the fur­nace. The infor­ma­tion gath­ered allows to low­er cor­ro­sion and foul­ing effects.
