燃?xì)廨啓C(jī)與LNG天然氣發(fā)電機(jī)組有沒有區(qū)別?
1.燃?xì)廨啓C(jī)機(jī)組主要設(shè)備包括了燃?xì)廨啓C(jī)、汽輪機(jī)、發(fā)電機(jī),沒有鍋爐(小容量余熱鍋爐除外),燃?xì)庠谌細(xì)廨啓C(jī)燃燒室燃燒做功,還推動(dòng)汽輪機(jī)帶動(dòng)發(fā)電機(jī)做功,整個(gè)機(jī)組發(fā)電容量包括了燃?xì)廨啓C(jī)本身容量和拖動(dòng)汽輪機(jī)容量,所以又叫作蒸汽燃?xì)饴?lián)合循環(huán)機(jī)組;
1. The main equipment of gas turbine unit includes gas turbine, steam turbine and generator. There is no boiler (except small capacity waste heat boiler). The gas is burned in the combustion chamber of gas turbine to do work, and the steam turbine drives the generator to do work. The generating capacity of the whole unit includes the capacity of the gas turbine itself and the capacity of the driven steam turbine, so it is also called steam gas combined cycle unit;
2、天然氣發(fā)電機(jī)組又稱LNG電廠,主要設(shè)備與一般的火電廠無(wú)異,只不過鍋爐的燃料從煤、油或者煤矸石啥的換成了天然氣,也是潔凈能源,但是燃料燃燒本身并不直接做功發(fā)電,仍然是通過加熱過熱蒸汽后推動(dòng)汽輪機(jī)和發(fā)電機(jī)做功發(fā)電。
2. Natural gas power generation unit, also known as LNG power plant, has the same main equipment as the general thermal power plant, except that the fuel of the boiler is changed from coal, oil or coal gangue into natural gas, which is also a clean energy source. However, the fuel combustion itself does not directly generate power, but it still pushes the steam turbine and generator to do power generation by heating superheated steam.
3、燃?xì)廨啓C(jī)是氣體燃料在氣輪機(jī)的燃燒室內(nèi)燃燒生成的高溫高壓燃?xì)庵苯油苿?dòng)氣輪發(fā)電機(jī)組做功發(fā)電,天然氣發(fā)電是燃料在鍋爐內(nèi)燃燒、加熱水后產(chǎn)生的高溫高壓蒸汽推動(dòng)汽輪發(fā)電機(jī)組做功發(fā)電。注意,一個(gè)是氣輪機(jī)、另一個(gè)是汽輪機(jī)。
3. Gas turbine is the high temperature and high pressure gas generated by the combustion of gas fuel in the combustion chamber of the gas turbine, which directly drives the gas turbine generator set to do power generation. Natural gas power generation is the high temperature and high pressure steam generated after the fuel is burned in the boiler and heated water to drive the steam turbine generator set to do power generation. Note that the other is a steam turbine.
4、LNG是英語(yǔ)液化天然氣(liquefied?natural?gas)的縮寫
4. LNG is the abbreviation of liquefied? Natural? Gas in English
5、蒸發(fā)氣體簡(jiǎn)稱BOG?閃蒸汽(Boil?Off?Gas)?用中文說(shuō)就是蒸發(fā)氣。來(lái)自產(chǎn)品LNG蒸發(fā)產(chǎn)生的甲烷氣
5. Bog? Off? Gas, in Chinese, is called evaporation gas. Methane gas from product LNG evaporation
6、EAG:Escape?air?gas?
6、EAG:Escape?air?gas?
LNG安全閥出來(lái)的氣體是低溫狀態(tài),密度較大,危險(xiǎn)性高。所以在出口加一個(gè)EAG加熱器(空溫復(fù)熱器),再進(jìn)行排空
The gas from LNG safety valve is in low temperature state with high density and high risk. Therefore, an EAG heater (air temperature reheater) is added at the outlet, and then the air is drained
