Abstract:
A method of incinerating sludge in a combustor is disclosed including establishing at least one target performance characteristic of the combustor; introducing the sludge into the combustor as primary fuel; monitoring at least one performance parameter of the combustor; calculating an actual performance characteristic based on the performance parameter; and adjusting the quantity and/or quality of fuel introduced into the combustor in response to a monitored performance characteristic to substantially maintain the target performance characteristic. The apparatus for incinerating sludge includes a combustor adapted to receive sludge as fuel and incinerate the sludge; a sensor that monitors at least one performance parameter of the combustor; and a controller connected to the combustor and the sensor that 1) establishes at least one target performance characteristic of the combustor, 2) calculates an actual performance characteristic based on the performance parameter and 3) adjusts quantity and/or quality of fuel introduced into the combustor in response to a monitored performance characteristic to substantially maintain the target performance characteristic.
Abstract:
Solid combustible waste materials are converted into highly efficient fuel by subjecting such materials to size reduction in suitable size-reducing equipment. The last piece of the equipment is a mill which pulverizes the waste materials into fine particles having a high surface to mass ratio and forming a highly efficient fuel when these particles are directly injected into a combustion reactor operating at high temperature.
Abstract:
A recycling system for a waste converting apparatus collects residues from a post-processing means and re-introduces the residues into the apparatus such that the residues are exposed to the high temperature zone thereof.
Abstract:
A system and method (100) for treating, injecting and co-combusting sludge in a municipal waste or other combustor is disclosed. The system includes a sludge receiving and treatment module (200) and a sludge injection and combustion module (300). The sludge is received and stored in one or more storage hoppers (1) where it is first diluted with a liquid (3) and subsequently mixed (13) to a desired homogeneous consistency suitable for pumping. The high liquid content sludge is then pumped (16) to a furnace injection nozzle (19) where it is preferably atomized with steam (29) and sprayed into the combustion zone of the furnace (20). The disclosed system and method increases sludge moisture content and controls the solids content of the sludge to control furnace temperature.
Abstract:
A process for the recovery of energy values from waste biodegradable material comprises passing comminuted waste material through a pyrolysis reaction chamber (13) and cooling the gaseous pyrolysis reaction product, in which the pyrolysis (24) and cooling chambers (14) are adjoining and the waste material is advanced through the pyrolysis chamber by advancement means comprising rotary drive shaft means (25) sealingly journalled through the wall of the cooling chamber remote from the pyrolysis chamber. The drive shaft gland (28) is therefore removed from direct exposure to the heat of the pyrolysis reaction and higher pyrolysis temperatures can therefore be tolerated, with a greater ability to treat biologically-active waste or other hazardous materials and a significantly faster processing time being achieved.
Abstract:
Die Erfindung betrifft ein Verfahren zur Einhaltung von Emissionsgrenzwerten in einem Brennprozess, wobei wenigstens ein Brennstoff (1) oder wenigstens ein Brennstoffgemisch zum Einsatz kommt, wobei der Brennstoff oder das Brennstoffgemisch über eine Zuführstrecke wenigstens einer Verbrennungszone zugeführt wird. Der Brennstoff (1) oder das Brennstoffgemisch wird während seiner Förderung zu der Verbrennungszone wenigstens einer ersten chemischen Analyse unterzogen, wobei die bei der ersten chemischen Analyse ermittelten Werte zur Regelung des Brennprozesses verwendet werden.
Abstract:
The present invention provides a process for the treatment of hazardous waste, the process comprising: (i) providing a hazardous waste; (ii) providing a waste stream; (iii) gasifying the waste stream in a gasification unit to produce an offgas and a char material; and (iv) plasma treating the offgas, and optionally the char material, in a plasma treatment unit to produce a syngas; wherein the hazardous waste is blended with the waste stream at a point in the process determined by the relative chemical and/or physical properties of the hazardous waste and the waste stream.
