Water problems are responsible for 90% of boiler accidents.
DrumPAK is a series of
packages designed to provide significant improvements
in maintaining boiler drum water level, stabilizing the
effects of feedwater pressure changes, and responding
to plant load changes. Installing DrumPAK can significantly reduce or
eliminate boiler shutdowns due to drum level or
feedwater pressure. DrumPAK not only helps
prevent loss of valuable production time and
materials, but increases the safety of your boiler.
A DrumPAK system more than pays for itself when
it prevents just one shutdown per year.
DrumPAK drum level and feedwater control systems are pre-enginereed, pre-configured packages that include instrumentation, pre-programmed controllers, and application-specific installation, startup and operation manuals. A DrumPAK package comes ready to install, with only a few parameters to enter from the front face of the controller to get up and running. Available for single-, two-, and three-element control, they can be installed as standalone systems or used in conjunction with other SteamPAK systems for total boiler control and efficiency improvement. |

DrumPAK-1 Single-Element Control Data Sheet
DrumPAK-1 is an easy and economic way to upgrade on-off level control to continuous control to reduce wear and tear on feedwater pumps and motors, and ensure a more consistent control around setpoint on smaller boilers, boilers with slow load changes, or systems without steam flow measurement. Only level measurement is required. DrumPAK-1 can be easily upgraded to two- or three-element control in the field as additional measurement devices are added.
DrumPAK-2 Two-Element Control Data Sheet
With the addition of steam flow measurement, DrumPAK-2 provides “shrink” and “swell” compensation and better response
to load changes. The controller calculates
the feedwater flow requirement based on level, and
uses the Steam Flow signal from a flow transmitter or
vortex meter as a feedforward signal to anticipate the
effect of steam demand changes on level.
DrumPAK-3 Three-Element Control Data Sheet
A three-element system adds measurement and
control of feedwater, which allows the system to
compensate for variations in feedwater pressure and
valve linearity. Variations in feedwater pressure result in significant changes in drum pressure, drum level and water temperature, causing the boiler to increase its firing rate and expend more energy as it attempts to recover full power. DRUMPAK-3 protects against this as well as reducing boiler trips due to unstable feedwater pressure. Large boilers or those with large or rapid
load changes benefit most from a 3-element control
system.
