Gas burning system, ignition system, lubricating system, cooling system, starting device, TRT etc..If boosting internal combustion engine generator
Group, should also there is pressure charging system.
Its NOx emission of the gas internal-combustion engine of standard type is 500mg/Nm3(5%O2), if taking the technologies such as lean burn to arrange
Apply, control engine cylinder temperature, its NOx emission also only can be controlled in 250mg/Nm3(5%O2) left and right, therefore, for environment
It is required that higher occasion, such as hospital, business district, residential area, to meet project environmental impact assessment requirement, may also need to further increase
Denitration facility.In addition, internal combustion engine smoke evacuation noise is generally higher than 110~120dBa, smoke evacuation muffler reduction noise need to be generally set up
It is emitted into and meets project environmental impact assessment and occupational health requirement.
Internal combustion engine used in the Distribution of Natural formula energy is higher due to NOx emission and noise, and generally project is typically installed
Near user, therefore bring disposal of pollutants also to adjoin the worry of user, in actual items implementation process, also face environmental impact assessment
Check requirements.For reduction NOx emission and reduction influence of noise, prior art is usually to carry out denitration process using SCR modes, separately

Limit；
2. internal combustion engine fume afterheat needs to make full use of to improve system primary energy utilization ratio, therefore, flue gas system
Need to generally increase the equipment such as flue gas lithium bromide chiller, waste heat boiler, flue gas heat-exchange unit recycle waste heat, its flue gas resistance compared with
Greatly.In addition, along with the equipment such as SCR denitration and flue gas muffler and flue gas pipeline SR, internal combustion may be exceeded
The general backpressure requirements scope of machine (5000~6000Pa of maximum), therefore, need to optimize reduction smoke evacuation system resistance as far as possible；
3. often individually consider each equipment skill of itself when the lectotype selection such as existing SCR denitration and flue gas muffler and design
, there is design iterations and requirement in art requirement.
