STEAM BOILER DISPLACEMENTS AS INDICATORS FOR CORRECT PROCESS CONDUCTING

Summary: Steam boiler is a large industrial agregate which is very sensitive to temperature variations. In the period of work the steam production and high temperatures cause displacements of the construction. The consequences are various: construction is flexibile and suspended on the springs, while large displacements lead to the cracks at the weak parts of the steam boiler. In transient startup period, which can be extended on a whole day, steam boiler changes its dimensions. Extremely high elongations occur in the vertical direction, where there are no constrains. Measurements of the displacements of the steam boiler were performed using telemetric equipment and displacement sensors. The measured values discussed in this paper, are result of one-year study of the steam boiler behaviour in thermo power plant. Results are important and were used to manage working parameters of the steam boiler.
