Furnace pilot control

A typi­cal field of appli­ca­ti­on of a pilot con­trol is, for exam­p­le, the opti­miza­ti­on or sup­ple­men­ta­ti­on of a cham­ber fur­nace con­trol by a pilot con­trol model. For a cham­ber fur­nace, a 1‑dimensional tran­si­ent ener­gy balan­ce model was crea­ted, para­me­ters with uncer­tain­ties (e.g. sur­faces from dimen­si­on reduc­tion, mate­ri­al data) were pro­vi­ded with line­ar factors.

The model was trai­ned with dif­fe­rent power/temperature cur­ves from preli­mi­na­ry tests. The graph shows the dif­fe­ren­ces of the tem­pe­ra­tu­re cur­ves at the con­trol ther­mo­cou­ple of the fur­nace con­trol befo­re and after the use of the pilot con­trol with the trai­ned pro­cess model. This shows how much a good pro­cess model can impro­ve the tem­pe­ra­tu­re con­trol in the furnace.
