IPT Engineering have recently completed the installation of Beck actuators on Europe's largest coal to biomass power station conversion. In total over 2GW (approx. 90%) of UK biomass generation now relies on Beck actuators for its control.
The actuators are supplied to both valve and damper applications.
Typical applications on biomass power station include;
ID Fan Dampers
FD Fan Dampers
BOFA Fan Dampers
Secondary Air Dampers
PA Fan Dampers
PA Cooler Dampers
PA Cooler Water Supply Valves
Fuel Route Diverter Valves
Fuel Route Isolation Valves.
Beck actuators were chosen for their ability to provide excellent modulating control on critical process elements, including ID and FD Fan Vane Control, BOFA Damper control, PA cooler dampers, and PA cooling water valves.
Initial results show that the inclusion of Beck actuators on these critical applications has improved boiler control and contributed to a significant reduction in Nox emissions to levels below that required by IED regulations.
IPT Engineering were able to provide qualified, experienced engineers to assist with all aspects of the project from planning and design, including HAZOP studies, design feasibility, DSEAR compatibility, through to installation and commissioning.
Beck actuators are available in a number of formats, modulating or on/off configuration, close coupled or linkage connected. The majority are suitable for operation in ATEX Zone 22 as standard, requiring nothing more than power and control supply to be connected. In most cases this will be ‘safe’ 120VAC single phase supply.
In operation they provide cost effective operation, having very low power requirements, typically less than 0.5amps, they are also virtually maintenance free, having no specific requirements.
In addition to the standard setting control capabilities provided by Beck drives, the station, after 4 successful years operating them on ID fan installations, were well aware of the outstanding reliability, and maintenance free characteristics of the actuators, and had no hesitation in specifying them for this project.
Both IPT Engineering, and Beck have unrivalled experience in providing actuation systems for critical combustion systems.
