Fire energy

火力發電是利用燃料,煤炭,石油,天然氣等之燃燒,藉由鍋爐蒸汽機等設備,將燃燒產生的熱能傳至水中,
Thermal power is from buring fuel,coal,rock oil and gas. Then transfer the heat to the water
from steam boiler buring.

使水化成高溫高壓之蒸汽來驅動發電機的葉片發電.
The water will become a very high temperture and pressure steam to make the blade of generator roll,then produce electricit.

其能量轉換大約分:化學能->熱能->機械能->磁能->電能
The energy transformation process:chemical->heat->mechanical->magnetic->electricity.

核能發電廠:
Nuclear power plant:

所使用的原料是鈾礦製程的燃料,利用核裂變反應所釋放的巨大熱能量來使高壓水變成高壓蒸氣,以
The main fuel is Uranium,transfer a huge heat to the water from nuclear fission.

此來推動發電機的驅動葉片,使之發電.
The water will become a very high temperture and pressure steam to make the blade of generator roll,then produce electricit.
