Central Heating Systems
How does it work?
Ulmatec Waste Energy Management System (Ulmatec WEMSTM) is a closed loop pressurized central heating system for maritime installations based on thermal fluid (water or water/glycol) circulation. The system is automated and self-regulating and a functional analogy can be drawn to electric power management. The basic function is to recover and transfer surplus thermal energy from main and auxiliary engines and distribute to connected consumer systems. Additional heating (for back-up or port mode) can be generated from electric or fuel fired heaters, but recovered heat will always be prioritized, ensuring maximum energy efficiency. Function for thermal storage is available. The system is applicable to any ship type and is applicable for newbuilds or retrofit to existing vessels. The system is highly configurable and can easily be adapted to customer needs and applied as:
- Low Temperature (LT) distribution/heating system (40°C - 60°C)
- High Temperature (HT) distribution/heating system (60°C - 85°C)
- Integrated Hybrid system with both LT and HT outputs
Most common power plant configurations with single or twin-engine room systems can be accommodated. For each, single or multiple engine installations can be served.
Features
Heat recovery
- Energy recovery from Exhaust gas system, HT-Cooling system, LT-Cooling system or fuel cells
- Fully automatic regulation of flow based on temperature levels
Heat generation
- Fuel fired heating by most common fuel types (MGO, MGO-Bio, HFO, LNG and combinations).
- Electric heating
Heat (thermal) storage
- Automatic charging of heat accumulation tank when surplus heat is available
- Automatic discharging of heat accumulation tank when consumer demand exceeds heat recovery
Heat distribution
- Automatic distribution of (energy) flows to individual heat consumers/consumer groups
- Physical installation flexibility – flow valve manifold or individual flow valve units
- Independent temperature set point for each consumer/consumer group
Waste Energy Management
- Main operator panel for managing system instances from Engine Control Room (ECR)
- Local touch control panel for each system instance
- Logging and visualization of energy (kWh) supplied (recovered and generated) and delivered (consumed)
- Interface to ships integrated automation system (IAS)
- Cyber-safe, on-demand remote diagnostics, monitoring and support
Benefits for ship owner
- Avoid dumping valuable thermal energy to sea or air
- Increased ship energy efficiency - lower fuel consumption and lower emissions
- Directly improves CII performance
- Monitor, manage and improve also your thermal energy consumption
- Intuitive graphical user interface (GUI) free up machinery crew’s time
- Draw attention to actual energy consumption and motivate for improvements
- Get guidance and assistance through remote diagnostics, monitoring and support
- Low maintenance and operating expenses (OPEX)
- Attractive payback (4 months – 2 years)
Benefits for ship yard
- Complete thermal energy system delivery from one supplier enables you to save time and costs in engineering, purchasing, installation and commissioning – avoid project delays and cost overruns
- Integrated and standard functionality between components - fewer interfaces to manage
- Standardized and quality assured software with required system control logic
- Significantly reduced cable installation work for same level of automation
- Flexible installation alternatives
- System P&ID with interface descriptions (electrical, instrumentation, piping, mechanical)
- Tagging and marking of components on demand
