Abstract

The NewGas project focuses on characterization of gas combustion emissions. The project studies the effect of the combustion process, fuel, lubricating oil and catalysts on the emission formation. In addition, different emission measurement methods are studied.
The earlier developed gas engine research facility was modified to be suitable for studies. Studies with natural gas and propane, as well as with two different lubrication oils and catalysts were done utilizing this facility. The exhaust hydrocarbon (HC) composition was found to be different from propane fuel compared to methane fuel (i.e. natural gas, NG) and no methane was found from the exhaust when using propane as fuel while ethylene, propene and propane were found. The particle mass emissions were low and total particulate matter (PM) resulted to same level with propane and NG fuels. However, remarkable differences were seen in particle number concentrations between fuels. For propane, nanoparticle emissions were significantly smaller than for natural gas. The change of lubricating oil was found to have some effect on the particle emission also.
High NOx reductions were observed when using selective catalytic reduction, although the level was not as high with propane fuel as was earlier observed in the case of natural gas fuel. The oxidation catalyst with higher activity was found to decrease also propane emissions and the emissions of particulate matter total mass. However, a catalyst combined with high exhaust temperatures increased nanoparticle number concentrations.
In this project, experimental field studies on gas combustion emissions were conducted at biogas and burner combustion facilities. The NOx, CO, methane and formaldehyde concentrations in the biogas engine exhaust were found to be relatively similar to what was measured on the research facility. This indicates that the catalyst studies done at research facility would be relevant also to this real application case utilizing biogas as fuel.
The results from the burner studies indicated that the NOx, CO and HC concentrations were all very low when measured downstream of the burner only.
