For a 600 MW supercritical parameter boiler

it carries out research on a combustion digital twin system to achieve digital and visual monitoring and precise control of the boiler combustion process.By digitally monitoring the water-wall temperature

single/multi-layer burner status

it analyzes key combustion parameters to guide precise control of boiler combustion.The application of digital twin technology for boiler combustion enables dynamic simulation of the three-dimensional temperature field of the entire furnace.Comparing the performance test results before and after the system putting into operation

the boiler efficiency increases

and the contents of combustible matter in the slag and fly ash decreases.The safety

stability

and economy of boiler combustion are all improved.
