Project Implementation and Operating Results
The enterprise is responsible for the comprehensive energy supply of the industrial park. Its combined heat and power system needs to cope with multiple scenarios of air usage, including steam network pressure regulation, pneumatic actuators of the desulfurization system, and instrument air supply. Different process links have differentiated requirements for pressure stability, air delivery, and energy efficiency levels, and the existing equipment has problems such as high energy consumption and frequent maintenance.
Technical adaptation
BOSAN has built a step-by-step air compression station solution for it:
BDS-50 Dedicated Constant Pressure Air Supply for Precision Instrument Control Systems
BDS-50 supplies the auxiliary pneumatic equipment in the desulfurization system; it does not replace the oxidation blower.
BDS-50 matches the peak air usage of the steam pipeline network pressure regulating valve set
The BDS-50 permanent-magnet variable-speed model is responsible for the flexible regulation of the base load.
Four devices achieve intelligent coordinated operation through a centralized control system, with the frequency conversion technology of BDS-50 serving as the core of system energy efficiency, capable of automatically switching to the optimal operating combination based on real-time load.
Implementation Effectiveness
The new system reduces the comprehensive air consumption in the plant 18%, and improves the equipment linkage response speed 60%. The BDS-50 series heavy-duty design adapts to the temperature differences in the north. The original project recorded annual downtime due to faults within 8 hours, which does not represent the guaranteed value for other units. The BDS-50 frequency conversion module also seamlessly connects with the customer's energy management system, providing real-time data support for carbon footprint monitoring. The entire solution reserves an air compression interface for future hydrogen boiler modifications.
The figures apply to this project and its specific operating conditions, not guaranteed results for other projects or the entire product series. Configuration and performance are subject to the project technical agreement.
