The fol­low­ing videos show how our Mobile High-Tem­per­a­ture Cam­era works togeth­er with our Tem­per­a­ture Sen­sor Sys­tems mon­i­tor­ing an online explo­sive clean­ing in the first pass of an RDS as well as some exam­ples of cam­era appli­ca­tions in the boiler.

CheMin experts have con­tributed an arti­cle to the vgbe jour­nal, the mag­a­zine of the tech­ni­cal asso­ci­a­tion of ener­gy plant oper­a­tors. It looks at in-situ fuel diag­no­sis and solv­ing prob­lems by using the boil­er as a con­tin­u­ous com­bus­tion lab.

Cer­tain fuels, par­tic­u­lar­ly those used in waste, RDF and bio­mass fur­naces are char­ac­ter­ized by het­ero­gene­ity and com­plex chem­i­cal com­po­si­tions. This caus­es stress to the boil­er, its com­po­nents, and its mate­ri­als. The fir­ing sys­tem that con­trols the incin­er­a­tion process in the fur­nace is fed by a large amount of sen­so­ry data yet the char­ac­ter­is­tics of the fuel remain unknown in the fir­ing system.

The con­cept of in-situ fuel diag­no­sis address­es this by uti­liz­ing the boil­er as a per­ma­nent com­bus­tion lab­o­ra­to­ry, mak­ing the hid­den prop­er­ties and process­es vis­i­ble. Meth­ods include the gen­er­a­tion of meta­da­ta through bal­anc­ing and mod­el­ling along­side spe­cif­ic sen­sor applications.

The basic idea of the in-situ fuel diag­no­sis is link­ing ther­mal uti­liza­tion of the fuel with the col­lec­tion of fuel prop­er­ties. This approach is advan­ta­geous and use­ful, as the nec­es­sary sen­sor appli­ca­tions are com­mon­ly avail­able and well estab­lished. Plants that are par­tic­u­lar­ly affect­ed include those fir­ing waste, RDF, bio­mass, lig­nite, and coal.
The indus­try is being pushed by legal and envi­ron­men­tal imper­a­tives asso­ci­at­ed with the cir­cu­lar econ­o­my towards inno­va­tion and new fuels. In-situ fuel diag­no­sis sup­ports the oper­a­tors of the plants in their efforts to achieve the goals of increased ener­gy effi­cien­cy and pow­er out­put and the reduc­tion of fos­sil CO2.

CheMin is delight­ed to be par­tic­i­pat­ing in the der Berlin­er Kon­ferenz für Abfall­wirtschaft und Energie, on Jan­u­ary 27 and 28. Andreas Lichtinger will give a pre­sen­ta­tion called ‘Air-Cooled Mobile High-Tem­per­a­ture Cam­era Probe for Flex­i­ble Use in Ther­mo-Chem­i­cal Process­es’, focused on the advan­tages and flex­i­bil­i­ty of the air cooled high-tem­per­a­ture cam­era probe devel­oped by CheMin.

CheMin’s Marie Kaiser will be con­tribut­ing to a webi­nar on 20 Novem­ber on explor­ing the pos­si­bil­i­ty of sub­sti­tut­ing fos­sil fuels with waste-derived alter­na­tives and apply­ing oxy­fu­el and chem­i­cal loop­ing com­bus­tion (CLC) tech­nolo­gies in the waste-to-ener­gy (WtE) sec­tor as a means of cap­tur­ing CO₂ emissions.

Marie’s pre­sen­ta­tion looks at cor­ro­sion mea­sure­ments in chem­i­cal-loop­ing com­bus­tion (CLC).
The event is a col­lab­o­ra­tion between ACT Louise and RFCS Rebecca.

Access is via Teams, and you can reg­is­ter here: https://act-louise.net/webinar‑2

CheMin is delight­ed to be par­tic­i­pat­ing in the 56th Pow­er Plant Tech­nol­o­gy Col­lo­qui­um, which starts in Dres­den on 8th Octo­ber 2024.

Marie Kaiser, our head of R&D, will give a pre­sen­ta­tion called ‘Corro­sion and foul­ingpoten­tial in chem­i­cal loop­ing com­bus­tion of sol­id waste-derived fuels with insuf­fi­cient reac­tor tem­per­a­ture con­trol’.

She will dis­cuss the results of online sam­pling using cooled probes at the 1 MWth test facil­i­ty in Darm­stadt, and look at the inter­ac­tions of the oxy­gen car­ri­er with the fuel at insuf­fi­cient tem­per­a­ture regimes.
