Enginnering is largely a practical activities. It’s about putting ideas into action.
Civil engineering is concerned with making bridges, roads, airports, etc.
Mechanical enginnering deals with the design and manufacture of tools and machines.
Electrical engineering is about the generation and distribution of electricity and its many applications.
Electronic engineering includes marine, automobile, aeronatical, heating and ventilating and others.
Electrical engineering includes electricity generating, electrical installation, lighting, etc.
Mining and Medical engineering belong partly to mechanical and partly to electrical.
Fuel transport and delivery
Coal may be delivered by transport truck or railroad cars. A large coal train may be nearly a mile long, containing 100 cars, each with 100 tons of coal, for a total load of 10,000 tons. Modern unloader use rotary dump devides. The unloader includes a train positioner arm that moves the entire train to position a car over a coal hopper. The dumper clamps an individual car against a platform, which swivels the car upside down to dump the coal. Swiveling couplers enable the entire operation to occur while the cars are still coupled together. Unloading a train take about 3 hours. Older unloader may still use bottom dump rail cars. Generating stations adjacent to a mine sometimes haul coal with massive diesel-electric drive truck with 140 tons capacity. Trucks this large typically have 8 ft (2.5 m) diameter tires, too big and heavy to be licensed for highway use.
For startup or auxilary purposes, the plant may use no.2 or no.5 fuel oil as well, fuel oil may be delivered by tank truck or train car. It is stored in vertical cylindrical steel tanks as large as 90,000 barrels (14,000 m3). The heavier no.5 “bunker” fuel must be steam heated before pumping in cold climates.
Natural-gas fuelled plants are usually built adjacent to gas transport pipelines or have dedicated gas pipelines extended to
