燃氣內(nèi)燃發(fā)電機組的特點
燃氣內(nèi)燃發(fā)電機組發(fā)電的工作原理是:空氣經(jīng)過濾清器過濾,進入渦輪增壓器增壓,導入內(nèi)燃機氣缸內(nèi)的混合器,瓦斯經(jīng)過壓力調(diào)節(jié)閥也進入混合器,兩者混合后,通過電子點火爆燃做功后,推動活塞移動和曲軸轉(zhuǎn)動,產(chǎn)生動力,帶動發(fā)電機,再由發(fā)電機將動力轉(zhuǎn)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(nèi)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(tǒng)、循環(huán)冷卻系統(tǒng)、潤滑油系統(tǒng)、電氣系統(tǒng)、控制系統(tǒng)等輔助系統(tǒng)。
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(nèi)燃機氣缸內(nèi)的核心區(qū)域工作溫度可以達到1400℃,使其效率大大超過了蒸汽輪機,甚至燃氣輪機。燃氣內(nèi)燃機zui突出的優(yōu)點正是發(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(nèi)燃機做功后的尾氣導入余熱鍋爐,回收熱量,產(chǎn)生過熱蒸汽,推動汽輪機組發(fā)電,實現(xiàn)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)動機單機功率小,需要多臺燃氣發(fā)動機的尾氣通過母管集合輸向一臺余熱鍋爐,多臺余熱鍋爐的蒸汽通過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
