1.  Steam Energy Management Solution

Role of the Steam System:

Steam is the primary heat transfer medium in many industrial processes such as heating, sterilization, steaming, and drying. It is a high-value energy source but prone to losses if the system is not optimally operated. Therefore, monitoring and controlling steam system efficiency is a critical element in a plant’s energy-saving strategy.

Steam Energy Management Solution:

1. 1. Boiler Performance Monitoring: Utilizes the Vortex flow meter Prowirl F 200, integrated with temperature and pressure sensors in a single device to accurately calculate steam mass generation. Combines steam data with feedwater and fuel (DO/FO) flow rates to calculate boiler efficiency in real time.

   2. Steam Quality Control (Saturated Dry Steam): The Prowirl F 200 features Wet Steam Measurement capability to detect and quantify moisture content, ensuring stable steam quality, enhancing heat transfer efficiency, preventing water hammer caused by condensate, and protecting equipment and piping.

   3. Steam Consumption Monitoring & Allocation: Installing steam flow meters at main usage points allows tracking consumption against KPIs by area, detecting steam leaks or improper loading, facilitating maintenance planning and optimizing steam distribution.

   4. Condensate System Optimization: Monitors recovered condensate volume to assess loss levels and reuse rates, thereby reducing energy needed to heat fresh water and lowering chemical treatment costs for feedwater.

Core Components of the System:

• • Prowirl F 200 Flow Meter: Accurately measures steam mass with Wet Steam Detection capability, resistant to vibration, high temperature, and pressure, ensuring stable operation in harsh environments.

  • Feedwater and Boiler Fuel Flow Meters (DO/FO): Provide input data for boiler efficiency calculation and control.

  • Temperature and Pressure Sensors: Monitor boiler operating conditions to ensure safety and prevent overheating or overpressure incidents.

  • Data Recorder: Collects and processes data from measurement devices, calculates energy efficiency, and continuously transmits information to the central management system.

  • SCADA System and Monitoring Interface: Visually displays real-time energy consumption indicators by area, analyzes data, forecasts trends, and issues timely alerts to maximize support for management and operation.

2.  Compressed Air Energy Management Solution

Role of the Compressed Air System:

Compressed air is one of the most energy-intensive utility systems, accounting for a significant portion of a plant’s total operating costs. Studies show that up to 30% of compressed air production is lost due to leaks, inefficient compressor operation, or improper usage.

Without strict monitoring and control, the compressed air system can become a major source of energy waste and increase production costs.

Compressed Air System Management Solution:

1. 1. Leak Detection & Consumption Management: Utilizes Endress+Hauser’s T-mass 300/500 flow meters to monitor total compressed air usage and key branch points. This facilitates easy identification of leaks, abnormal consumption periods, and assessment of compressed air losses.

   2. Compressed Air Quality Monitoring: Strictly controls moisture and dew point temperature to protect piping, pneumatic equipment, and ensure final product quality. This minimizes condensate-related corrosion, extends equipment lifespan, and reduces maintenance costs.

   3. Filter Monitoring & Operating Pressure Control: Measures differential pressure before and after filters to determine cleaning or replacement timing. Ensures the system does not experience excessive pressure loads, thereby reducing compressor energy consumption.

   4. Energy KPI Establishment: Quantifies compressed air usage efficiency through KPIs such as kWh/m³ of compressed air, percentage of air loss, and compressed air costs by area or product. This enables precise cost control and optimized operational planning by management.

   5. Data Integration with Energy Management Software: Integrates measurement device data into the Energy Management System, automating compressed air consumption reporting and allocating costs by production area.
