Abstract: Various techniques are described for enhanced combustion of hot water extraction (HWE) derived liquor. For example, the HWE derived liquor can be pre-treated prior to introduction into a combustion chamber. The pre-treatment can include subjecting HWE derived liquor to filtration to remove suspended solids, evaporation to produce a first stage concentrated HWE liquor; additional concentration to produce a second stage concentrated HWE liquor; additional filtration to remove additional suspended solids; and pre-heating to produce a preheated HWE liquor. The preheated HWE liquor can be atomized and combined with pre-heated combustion air supplied into a combustion chamber to effect combustion of the HWE derived liquor.

Abstract: A method for treating waste gases contaminated with toxic or odorous compounds in the form of a mist using a regenerative incinerator system is provided. The contaminated waste gas is passed through a first regenerator so that the waste gas is heated by contact with the packing material contained therein. This hot contaminated waste gas is passed through a combustion chamber to oxidize the compounds in the waste gas. The hot treated waste gas is passed through another regenerator to cool the gas and heat the packing material contained therein. The cleaned gas is discharged. Part of the cleaned gas is heated and passed through the regenerator to volatilize and/or remove compounds remaining in the regenerator after passage of the waste gas, thereby cleaning the regenerator.

Abstract: A collector for filtering gases containing dust. The dust collector includes a metallic woven fabric having pores of a size ranging between 15 and 80 microns. This fabric is for instance a Dutch twill preferably made up of stainless steel. A method for removing and collecting from gases, dust, is also disclosed. Wherein the gases are passed through a metallic woven fabric having pores of a size ranging between 15 and 80 microns. Auxiliaries to remove the particles from the fabric are also disclosed.
