Kurzfassung

A Czech SME specialised in the development and production of waste incinerators offers a technology application for removal of dioxines from combustion products and gases. The technology is mainly designed for small and medium combustion plants (up to 1000 tons per year) of hospital, industrial and chemical waste. The technology meets Directive EU 2000/76/EC on waste incineration and European emission limits. The company offers commercial agreement with technical assistance.

Details

The construction of new incinerating plants as well as the operation of the existing ones treating municipal waste and, on the first place, hazardous waste is permitted only in case of demanded purification of combustion products and gases.
From the point of view of contamination of combustion products and gases, it is the presence of halogenated polyaromatic compounds having a high degree of toxicity, carcinogenicity and teratogenicity that is extraordinarily dangerous. First of all these are polychlorinated dibenzodioxines and dibenzofuranes marked with the abbreviation PCDD/F. There is a great number of PCDD/F types differing not only as for their composition but also for their degree of toxicity. In terms of EU rules, it is the emission limit up to 0.1 ng/m3 of combustion products.

The procedure mostly used for the removal of PCDD/F from combustion products is the adsorption technology using carbonaceous sorbents – active coal.
Offered technology makes possible to reach the residual amount of PCDD/F below the admissible limit of 0.1 ng/m3 by using special types of carbonaceous sorbents with a high efficiency as well as sorption capacity.

Each technology application precedes a selection of type of incinerator, its capacity and the process design in view of environment protection, economy of operation and specification of the wastes types and quantities. Engineering before the installation deals with:
- transport routes of waste, waste management, preparation of waste for charging and charging methods;
- methods of heat extraction and its efficient use;
- methods of flue gas cleaning with a view of compliance with the standards of general force and other special requirements presented by the investor or other parties to the building permit proceedings;
- measurement and control system within a minimum scope defined by the regulations in effort or above-standard installations providing more comforts if requested by the investor;
- incinerator waste management.

The implementation of the installation is in compliance with the investor’s possibilities, either in smaller deliveries or a comprehensive delivery of the process and civil part, so called turnkey delivery.

Innovative Aspects:
This technology intensifies the purification process presenting, at the same time, the application of the latest knowledge. It also applies the knowledge of world technology of the latest period.

Basic Features of this Innovation Technology Are:
a/ a technical innovation and a high variability as for the structural solution of units in dependence on local conditions of incinerating plants;
b/ a special type of sorbent having the below-cited typical features:
- a high specific surface, above 1000 m2/g, with a high capacity and efficiency as for the removal of PCDD/F and PCB;
- a high porosity, above 3.5 cm3/g, accelerating the transport of PCDD/F and PCB from combustion products to the active surface, where they are trapped;
- a small size of basic particles, i.e. approximately 20.10-6 mm, capable to group (agglomerate) around contaminating substances and to bond them irreversibly;
- a small size of particles enabling the creation of approximately 2 mill. particles in 1 m3 of combustion products creating, thus, a perfect homogenizing environment of sorbent in the whole volume resulting in a high efficiency and removal of PCDD/F and PCB within an extraordinarily short period;
- a surface with a fixed sure amount of colloidal sulphur enabling chemisorptive trapping of heavy metals;
- the content of a trace amount of oxidation catalyser.

This technology enables to meet the European limits relating to removal of contaminating components from combustion products with a sufficient reserve (approximately 50% or even more).
