An emissions control system efficiently reduces combustion waste products
emitted from a trailer-mounted mobile electrical power generation system.
The invention also reduces noise levels associated with power generation.
The invention includes several road-transportable duct modules that can
be connected together. One module directs the flow of combustion gases
from the exhaust of a combustion engine in a power trailer and also
provides noise attenuation. Another module mixes the combustion gases
with a urea mixture. A third duct module houses a catalyst for removing
combustion waste products.
