Compensator 238824

The compensator is a critical component in the fuel gas system of gas engines. Its primary function is to ensure stable and precise gas pressure regulation at the inlet of the gas mixer or throttle valves, compensating for fluctuations in the upstream gas supply pressure.

Key Roles:

Pressure Stabilization: It maintains a constant, engine-required gas pressure, protecting the engine from irregularities that could affect performance or emissions.

Safety & Control: By providing a stable pressure, it enables precise air-fuel ratio control, which is essential for efficient combustion, optimal power output, and low NOx emissions.

Protection: It safeguards downstream components (e.g., actuators, valves) from pressure spikes or drops.

Operation and Use:

The compensator is typically installed in the gas train upstream of the final control valves. It is a self-contained, mechanical diaphragm-operated regulator. Its operation is automatic:

The internal diaphragm adjusts based on the downstream pressure signal (usually taken from the gas mixer).

It automatically modulates its internal valve to increase or decrease the gas flow, thereby maintaining the set outlet pressure regardless of inlet variations.

The desired outlet pressure is set during engine commissioning and requires no regular adjustment.

In summary, the compensator (238824) is a vital, maintenance-free regulator that ensures consistent fuel gas pressure, directly contributing to the engine's reliable, efficient, and compliant operation.
