燃氣內燃發(fā)電機組的特點(diǎn)
燃氣內燃發(fā)電機組發(fā)電的工作原理是:空氣經(jīng)過(guò)濾清器過(guò)濾,進(jìn)入渦輪增壓器增壓,導入內燃機氣缸內的混合器,瓦斯經(jīng)過(guò)壓力調節閥也進(jìn)入混合器,兩者混合后,通過(guò)電子點(diǎn)火爆燃做功后,推動(dòng)活塞移動(dòng)和曲軸轉動(dòng),產(chǎn)生動(dòng)力,帶動(dòng)發(fā)電機,再由發(fā)電機將動(dòng)力轉換成電能,經(jīng)輸變電裝置輸出。
The working principle of the gas-fired internal combustion generator set is: the air is filtered through the filter, enters the turbocharger for pressurization, and is introduced into the mixer in the cylinder of the internal combustion engine. The gas also enters the mixer through the pressure regulating valve. After the two are mixed, the piston moves and the crankshaft rotates to generate power and drive the generator, Then the power is converted into electric energy by the generator and output through the power transmission and transformation device.
為了保障內燃機和發(fā)電機兩大主機的正常運行,必須配備燃氣儲存、加壓和處理系統、循環(huán)冷卻系統、潤滑油系統、電氣系統、控制系統等輔助系統。
In order to ensure the normal operation of internal combustion engine and generator, auxiliary systems such as gas storage, pressurization and treatment system, circulating cooling system, lubricating oil system, electrical system and control system must be equipped.
由于內燃機氣缸內的核心區域工作溫度可以達到1400℃,使其效率大大超過(guò)了蒸汽輪機,甚至燃氣輪機。燃氣內燃機zui突出的優(yōu)點(diǎn)正是發(fā)電效率比較高,其次是設備集成度高,安裝快捷,對于氣體中的粉塵要求不高,基本不需要水,設備的單位千瓦造價(jià)也比較低。
Because the working temperature of the core area in the cylinder of internal combustion engine can reach 1400 ℃, its efficiency is much higher than that of steam turbine or even gas turbine. The gas-fired internal combustion engine Zui has the outstanding advantages of high power generation efficiency, high equipment integration, fast installation, low requirements for dust in the gas, basically no water, and low cost per kilowatt of equipment.
余熱發(fā)電機組的工作原理是:燃氣內燃機做功后的尾氣導入余熱鍋爐,回收熱量,產(chǎn)生過(guò)熱蒸汽,推動(dòng)汽輪機組發(fā)電,實(shí)現燃氣蒸汽聯(lián)合循環(huán)發(fā)電。
The working principle of the waste heat generator unit is: the tail gas after the work of the gas internal combustion engine is introduced into the waste heat boiler to recover heat, generate superheated steam, promote the power generation of the steam turbine unit and realize the gas steam combined cycle power generation.
由于燃氣發(fā)動(dòng)機單機功率小,需要多臺燃氣發(fā)動(dòng)機的尾氣通過(guò)母管集合輸向一臺余熱鍋爐,多臺余熱鍋爐的蒸汽通過(guò)蒸汽母管輸入一臺蒸汽輪機
Due to the small power of single gas engine, the tail gas of multiple gas engines needs to be transmitted to one waste heat boiler through the main pipe, and the steam of multiple waste heat boilers is input to one steam turbine through the steam main pipe
