Pressure jet burner for ship's boiler
KBP™ | 1,200 – 8,000 kg/h Aalborg Industries

The KBP™ burner was originally designed together with the MISSION™ OS-TCi oilfired boiler in order to get an integrated design, where the two components are matched for the highest combined performance and lowest CO2 emission. The KBP™ burner meets customer demands for reliable operation, easy maintenance and
minimum installation requirements.

The burner design is based on Aalborg Industries’ long-term experience in marine boilers and combustion technology, ensuring optimum burner performance. The working principle of the pressure jet burner is atomizing by oil pressure through a nozzle (in brand name KBP™, the P = pressurized).

The oil enters the atomizing nozzle at a pressure of approximately 30 bar(g) and is pressed through the small nozzle holes, which ensures a fine mist of oil droplets into the combustion zone, where the oil droplets are mixed with the combustion air. The combustion air enters the damper at the bottom of the burner house.

The fan is integrated in the fan house and ensures the required air flow and velocity around the oil lance. A diffuser disc is mounted on the lance to ensure full mixing of air and oil, which ensures a complete combustion of the oil.

The oil components are all placed behind a door on the side of the burner, where they are easily accessible. The electrical parts are placed above the oil components behind another door, so no oil can spill into the electrical parts. Access to the diffuser disc and nozzle is given through a top cover, which can be opened and afterwards
the lance can be withdrawn and easily serviced.
