Pollutant Emission Reduction Analysis of Distributed Energy Resource

Environment directly affects human health. The literature firstly introduces the distributed energy resource and its category. Five systems, including three natural gas micro-turbine systems, one Phosphoric Acid Fuel Cell combined heat and power system and one Proton Exchange Membrane Fuel Cell system are taken as the object. Pollutant concentration and emission rate measurements for nitrogen oxides (NO_X ), carbon monoxide (CO) and total hydrocarbons (THC) were conducted in the exhaust stack. The mass emission rates are normalized to power output and reported as grammas per kilowatt hour (g/kWh). The emission for the systems at different load ratio and emission for per kWh are analyzed. The conclusion is that: the emission for a distributed energy system has direct connection with load ratio. Generally, the emission at 100% load ratio is much lower than at other load ratios. And it can be predicted that distributed energy resource has bright prospects.
