Nivåreglering av ångpanna i turbintanker
(1975) In MSc ThesesDepartment of Automatic Control
- Abstract
- When controlling the drum water level of marine boilers the rolling of the ship may cause problems. The drum water level gets a sinusoidal disturbance, which causes a disturbance of the feed water control valve. This disturbance may proceed through the feed water pump to other steam consumers. The rolling inflates other boiler parameters too. It will be shown that stability problems may appear if the disturbances are eliminated wrongly. This work will show how a feed forward signal from the steam flow can decrease the roll effects and yet improve the control of the level by load changes.
