Abstract: A flueless primary combustion chamber forms a part of a pollution control incineration system having an elongated duct having one or more inlets positioned at or near grade level. An upright standpipe removably covers an inlet opening to provide a polluted gas inlet to the duct from a location elevated above grade. The primary combustion chamber is constructed with a closed top and an open bottom which removably overfits the standpipe in a manner to allow combustible material to be burned within the shell and to direct the gases of combustion downwardly into the duct through the top of the standpipe.

Abstract: A pollution controlled incinerator system comprises an elongated combustion products duct system having a series of spaced incineration station inlets positioned above ground level and a permanently installed pollution control apparatus. The branch combustion product duct from a remote station terminates at a more proximate station whereby when two or more portable incinerators are installed, the combustion products from the incinerator station further from the pollution control apparatus pass through the charge of the next proximate incinerator station in the series. The combined combustion products effluent from all of the incinerators or furnaces installed along the duct system is concentrated and directed to the permanently installed pollution control apparatus. The pollution control apparatus functions to clean and to cool the combustion products effluent and then to discharge the effluent to atmosphere.

Abstract: A pollution control incineration system comprises an elongated duct having one or more inlets positioned at or near grade level. An upright standpipe removably covers an inlet opening to provide a polluted gas inlet to the duct from a location elevated above grade. The duct terminates at its remote end in a combination flue and pollution control system which may include pollution control devices such as an afterburner chamber, a water spray cooling chamber, a baghouse and an induced draft fan. A portable, shell type primary combustion chamber removably overfits the standpipe to allow combustible material to be burned within the shell and to direct the gases of combustion downwardly into the duct through the top of the standpipe.
