Definitions
- the invention relates to a method for burning plastic waste.
- plastic waste for example in private households incurred, either landfilled in a mixture with the residual waste or burned in domestic waste incineration plants.
- the fireboxes The domestic waste incineration plants are based on the current state of development predominantly designed as grate firing, the regarding the thermal design for the calorific value of household waste are aligned. Pure plastics can because of the very much higher calorific value and the low melting point there not used alone (risk of sticking). As a result would need the plastic fraction that sorts out of household waste was used for thermal recycling in a domestic waste incineration plant be mixed homogeneously with the residual waste.
- the method that solves the problem is that the a determined grain size by means of ground plastic waste a separate blowing device independent of the burner in led a combustion chamber of a dust burner and ignited there be, the blowing device is designed such that the trajectory of the ground plastic waste to complete Combustion remains in the area of high temperatures for a sufficiently long time.
- a gaseous fuel e.g. Natural gas G or a Cooling air flow in a second tube, concentric around the inner tube, and the preheated combustion air L with or without coal loaded in a third, concentrically guided around the second tube Outer tube added to a combustion chamber 2.
- the management of fuel and gas flows take place in such a way that thorough mixing, good flame stability and complete burnout guaranteed is.
- the plastic K can be separated Lance 3, which can be cooled or uncooled, in the Combustion chamber 2 are added so that the trajectory of the plastic particles long enough for complete combustion High temperature area lingers.
- plastic waste are homopolymers and copolymers of ethylene Propylene, styrene and polyamide as well as any mixtures these substances even in the presence of PVC and PET and in compositions, which correspond to the plastic fraction in household waste, can be used if the maximum grain size is less than 2 mm.
- plastic waste both over the burner 1, however separated from the coal and air flow, as well as separately via an additional lance 3 can be introduced into the combustion chamber 2.
- All coal (hard and brown coal) and usual fuel gases (e.g. natural gas, town gas, synthesis gas etc.) in any proportions can be used, with the burnout increasing Improved load share of the plastic.
- the best burnout and emission results were tested in pilot plants a thermal load share of the plastic of 50 to 80% Hard coal support firing and addition of the plastic via a separate Lance achieved.
