Description
This dataset represents electricity generation from representative natural gas-fired power plants in Hubei, China. The electricity generation efficiency is derived from the regional average efficiency of thermal power plants, representing the typical performance of natrural gas-fired electricity generation in the region. Key emission inventory data are compiled as follows:
· CO2, particulate matter, and flue gas emissions are primarily estimated based on material balances and pollution generation factors related to gas quality parameters, assuming that NOx emissions comply with the standard limits for pollutants from thermal power plants.
· CH4 and N2O emissions are estimated using the default emission factors for natural gas combustion in the energy sector as specified by IPCC 2006. - Primarily considered particulate matter emissions with particle size less than 2.5 μm.
· All emissions take into account the average removal efficiency of flue gas pollution control technologies in Chinese thermal power plants.
Activity Description
The product's production activity boundary covers the entire operation and maintenance phase of the power plant, including fuel combustion, flue gas denitrification, and particulate matter removal. The water treatment process for process water used in power generation is described in a separate dataset: cooling water treatment and softened water treatment.
Process Description
The product is grid-connected electricity measured in kWh, with a voltage level of ≥35 kV.
