Aalborg OM-TCi
The Aalborg OM-TCi is a highly efficient, vertical cylindrical boiler, producing either steam or hot water with capacities ranging from 8,000 to 20,000 kg/h. This versatile boiler is designed to operate on gas and a variety of fuels, including modern options like methanol and biofuels. Furthermore, it offers an optional setup for electrical steam generation, utilizing clean electricity from shore power connections.
Efficient boiler for diverse fuels, ensuring reduced emissions.
- High thermal efficiency range 89 - 92% with low fuel consumption as a standard concept
- Thermal efficiency can be further improved up to 93 - 96 % (LHV) by adding an external economizer
- The standard boiler can be fired with gas and various fuels, like methanol and biofuels.
- Option for electrical steam generation with shore-power and clean electricity
- Proven design, ready to install and easy to operate and clean
Building on a foundation of proven technology and extensive experience, the Aalborg OM-TCi fired steam boiler represents a significant advancement. Its upgraded thermal design, featuring optimized flue gas oxygen content, achieves a remarkable total efficiency of 89–92%, depending on boiler load. This efficiency is, on average, a substantial 6% higher than typical boilers within the same capacity range.
The direct result of this enhanced efficiency is reduced fuel consumption and significantly lower CO2 and NOx emission levels. To illustrate the impact, consider a 16,000 kg/h boiler operating 5,000 hours annually at 75% load: this translates to an approximate annual saving of USD 170,000 on fuel costs (based on a fuel price of 650 USD/ton).
Thermal efficiency and savings can be further improved using Aalborg Micro as an external exhaust gas economizer reducing the use of the fired marine boiler by recovering heat energy that otherwise would be lost through the engine exhaust gas.
Service
We provide full support for our fired boilers. Our support covers their entire life cycle, beginning with design, installation and commissioning and extending past warranty throughout the service life.
Alfa Laval Service Agreements will help the operators of the systems. A fixed-period Service Agreement makes operation planning and cost projections more secure. A well-crafted maintenance strategy offers transparent cost control and safeguards performance, lengthening your equipment’s lifespan and reducing your total operating costs. Preventive maintenance is the key to reliable performance. Our Preventive Maintenance Programme comprises annual and 30-month services that comply with regulatory inspection schedules.
How it works
Furnace
Aalborg OM-TCi consists of a large furnace with gas-tight membrane walls. A sufficient number of downcomers ensures safe natural circulation, and adequate furnace dimensioning guarantees good combustion and low emission, moderate loading and low material stresses.
Convection part
A cylindrical shell surrounds the smoke tubes and the water/steam space. These smoke tubes have enhanced heat transfer features guaranteeing low exhaust gas temperature and thus high efficiency.
Burner & Control System
The boiler will be delivered with a multi-fuel burner, which is designed to automatically modulate according to the system’s heat demand. The burner is designed for a high turndown ratio with complete combustion at low oxygen levels. To ensure optimal combustion, pressurized air or steam is used as an atomizing media. The burner adjusts automatically, but the operator can switch to manual control if needed. The burner system allows the use of various alternative fuels, as well as the combustion of boil-off gas from gaseous fuels (GCU functionality, gas combustion unit).
The burner and the boiler are controlled by a specifically designed and standardized control system, which is included in the delivery. This system consists of all the required components for the heat recovery system according to Alfa Laval standards, including the main control with HMI-panel located in each engine room. The control system enables connectivity and intelligent data collection, and it has the capacity for remote
support. In systems with two engine rooms, each has its own control system, but they communicate and work seamlessly together, enabling flexible operating modes.
