Aalborg OM-TCi

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.
