Study Notes
Legal Responsibilities of Engineers
- Engineers must notify inspectors of any known or suspected defects during inspections.
Fired Hot Oil Heater Tubes
- Extended type tubes feature fins on their outer surfaces, enhancing heat transfer efficiency.
Diesel Engine Injection Pump
- The injection pump is driven by a camshaft, facilitating proper fuel delivery.
Ammonia Properties
- Ammonia is toxic and flammable, posing significant safety hazards in various applications.
Boiler Priming
- Boiler priming indicates water is being carried over with steam, which can affect performance.
Steam Engine Slide Valve
- The slide valve is designed to manage steam entry and exit in the cylinder, essential for efficient operation.
Journal Bearings
- Journal bearings support shafts and require adequate lubrication for effective functioning.
Spark Ignition Engine Fueling
- Carburetion is used in smaller spark ignition engines to vaporize gasoline for combustion.
Heat Load from Occupants
- The primary factor affecting heat load from people in a room is their activity level, impacting overall heating needs.
Safety Valve Testing
- Pulling the try-lever ensures safety valves on boilers are free to operate, a critical aspect of safety assessments.
Unitary Air Conditioning Systems
- Window air conditioners utilize direct expansion refrigeration for cooling and dehumidification without ductwork.
Oil Load Support
- Viscosity is the key property that indicates an oil's ability to support a load, influencing lubrication effectiveness.
Fired Heater Furnace Lining
- The inner surfaces of fired heater furnaces are lined with refractory material for heat resistance.
Collar Thrust Bearings
- These bearings have boundary lubrication capabilities and are suitable for supporting substantial loads.
Operating Parameters for Hot Oil
- The temperature of hot oil leaving the heater is a critical operating parameter for system performance.
Heat Sources for Buildings
- Buildings require heat sources to compensate for heat losses, ensuring indoor comfort and energy efficiency.
Condensate Return System Issues
- Grooving and thinning in condensate return systems are caused by carbonic acid corrosion, affecting system integrity.
Minimizing Freezing in Steam Coils
- Installing preheat coils that are controlled by outdoor temperature can help mitigate freezing problems in long steam coils.
Blow-off Valve in Storage Heaters
- The blow-off valve is essential for removing sediment from the base of the heater, promoting efficient operation.
Antifriction Bearings Maintenance
- Antifriction bearings utilizing grease still require periodic cleaning and maintenance to ensure optimal performance.
