Purpose:
A diesel fire pump exhaust system safely removes combustion gases (carbon monoxide, nitrogen oxides) and heat generated by the engine.

Key Components:
Exhaust Piping: Directs exhaust fumes outside the pump room.
Silencer/Muffler: Reduces noise levels for compliance with local regulations.
Heat Shields: Prevents overheating of surrounding equipment.
Flexible Joints: Allows for thermal expansion and vibration control.
Best Practices:
Ensure proper ventilation to prevent backpressure and heat buildup.
Comply with NFPA 20 and local emission regulations.
Use insulated exhaust pipes to protect nearby components.

Key Selection Factors:
Battery Type: Sealed lead-acid (SLA) and nickel-cadmium (NiCd) are common choices for reliability.
Capacity & Cold-Cranking Amps (CCA): Ensure the battery has sufficient power to start the diesel engine in all conditions.
Charging & Maintenance: Use a dedicated battery charger and test regularly to prevent failures.

Why It’s Important:
Diesel fire pumps generate heat and exhaust gases that must be properly managed to prevent overheating, maintain engine efficiency, and ensure compliance with NFPA 20 standards.

Best Practices:
Calculate Airflow Needs: Ensure the pump room has adequate airflow to dissipate engine heat and remove exhaust fumes. The required ventilation is based on engine size and heat generation.
Install Proper Louvers & Exhaust Fans: Position intake and exhaust louvers correctly to maintain a steady flow of fresh air. Exhaust fans help remove hot air efficiently.
Direct Radiator Exhaust Properly: If the diesel engine is radiator-cooled, make sure the exhaust is directed out of the building to prevent heat buildup.
Monitor Temperature Levels: Use temperature sensors and alarms to detect overheating risks.
