A mobile vessel which reduces the transmission of noxious fumes into the surrounding atmosphere emanating from material contained in a material chamber in the vessel, such as bituminous roofing material. An air plenum extends along the vessel beneath a filtration unit and receives noxious fumes from the material chamber and from an outside source through ducts. Ambient air is mixed with the fumes for cooling the fumes upstream from the filtration unit. A heater and stirrer are located within the material chamber for uniformly heating the material. A power operated ram and heated breaker bars move and break a solidified key of the material for subsequent discharge into the material chamber. A blower creates a negative pressure in the air plenum and filtration unit for moving the fumes and ambient cooling air therethrough.

[ We claim:] [1.] A mobile vessel for reducing the transmission of noxious fumes into the surrounding atmosphere emanating from a material contained in the vessel, said vessel including:a material chamber for containing a quantity of the material;heater means in the material chamber for heating said material;a filtration unit having an inlet and an outlet extending generally horizontally throughout a substantial length of the vessel;an air plenum separated from the material chamber and communicating with the inlet of the filtration unit, said air plenum having an inlet end and an outlet end and extending generally horizontally throughout a substantial length of the vessel in juxtaposition to the filtration unit with said outlet end being in communication with the inlet of said filtration unit whereby fumes entering the filtration unit reverse direction of movement upon leaving the outlet of the air plenum;first duct means for transferring fumes emanating from the material within the material chamber into the air plenum, said first duct means having a cross-sectional area smaller than the cross-sectional area of the air plenum whereby the fumes have a lower velocity when moving through the air plenum than when moving through said first duct means;a material feed compartment communicating with the material chamber;blower means for creating a negative pressure in the air plenum, filtration unit and material feed compartment for moving the fumes through the first duct means and through the filtration unit then into the atmosphere; andpump means communicating with the material chamber for delivering material from said chamber to a remote location outside of the vessel.
