Siemens Energy has been granted a patent for a pre-combustion chamber system that improves fuel and air mixture in a combustion chamber. The system includes a flow agitator that increases flow disturbance, enhancing the mixing process. Additionally, the cooling of the system is improved by dividing the cooling chamber into separate chambers or by using cooling fins.

Improved pre-combustion chamber system with enhanced flow and cooling
A recently granted patent (Publication Number: US11686242B2) describes a pre-combustion chamber system and method for its production. The system includes a pre-combustion chamber housing that surrounds an interior cavity, a cooling chamber housing that surrounds the pre-combustion chamber housing, and a flow agitator arranged in the pre-combustion chamber housing. The flow agitator is designed to increase flow disturbance in the pre-combustion chamber, improving combustion efficiency.
The system also features a panel that divides the cooling chamber into a cooling inlet chamber and a cooling outlet chamber. This panel is sealed together with the pre-combustion chamber housing and the cooling chamber housing at the top portion, leaving an opening at the bottom of the cooling chamber. The cooling inlet chamber and the cooling outlet chamber communicate with each other through this opening.
The flow agitator can be in the form of an inclined protrusion or a straight protrusion, with one end located at a lower longitudinal location than the other end in the pre-combustion chamber housing. It can also span at least a sector of the circumference of the pre-combustion chamber housing. Multiple flow agitators can be arranged in the pre-combustion chamber housing to further enhance flow disturbance.
The method for making the pre-combustion chamber system involves forming the flow agitator in the pre-combustion chamber housing and creating the panel between the pre-combustion chamber housing and the cooling chamber housing. The panel is formed to divide the cooling chamber into the cooling inlet chamber and the cooling outlet chamber, with communication between them through the opening at the bottom of the cooling chamber.
Additionally, the pre-combustion chamber itself is described as having a pre-combustion chamber housing, a cooling chamber housing, and a panel that divides the cooling chamber into the cooling inlet chamber and the cooling outlet chamber. A cooling fin is also included, extending into the cooling chamber from the pre-combustion chamber housing.
Overall, this patent presents a pre-combustion chamber system and method that aims to improve combustion efficiency by increasing flow disturbance and optimizing cooling chamber design. The system's unique features, such as the flow agitator and the divided cooling chamber, contribute to enhanced performance in combustion processes.
