Report on national contribution “in-kind” of the Republic of Belarus into EMEP for 2002 Sergey Kakareka, Tamara Kukharchyk, Valery Khomich Institute for Problems of Natural Resources Use & Ecology Minsk, Belarus 4rd JOINT UNECE Task Force & EIONET Workshop on Emission Inventories and Projections September 2003, Warsaw, Poland MSC-East

Project title: Goals:  Improvement of the Guidebook in view of peculiarities of the FSU specificity  Promotion of the Guidebook methodology usage in the FSU countries Budget: 2753 US$ Preparation of additions and refinements to the EMEP/CORINAIR Atmospheric Emission Inventory Guidebook regarding heavy metals emission in view of peculiarities of the CIS countries technologies

Executive Summary Experimental researches, analysis of literature sources, investigation of technological peculiarities of the Former USSR countries made possible to prepare additions and materials for inclusion to the Guidebook. In all such additions and materials were prepared for 10 Guidebook chapters. Special attention was paid onto source categories which are not considered in the Guidebook yet (stationary fuel combustion – small appliences), or slightly considered (open burning sources). New experimental data on HM emission.

Small combustion installations In general small combustion devices can be divided into the next main groups:  installations close to open combustion (from this category fireplaces are most common in Europe);  installations without heat-transfer (furnaces, ovens, stoves);  installations with heat-transfer (mainly water or steam) – various types of boilers. Small combustion devices are very different in design. Most specific are solid fuel burning systems; liquid and gaseous fueled installation are often can be fueled by both these types of fuel (with some reequipment). ADDITIONS TO THE EMEP/CORINAIR GUIDEBOOK

Small Boilers Generally boilers are distinguished as steam and hot-water, functioning with natural or induced circulation. According to their design, steam and hot-water boilers are classified into: straight-through; single-drum with natural circulation; double-drum with natural circulation; flue with fire tubes; and gas-tube waste-heat boilers. Low capacity boilers operating on solid fuel are classified into boilers with manual furnace, heat efficiency from 0.1 to 0.8 Gcal/hr and boilers with mechanical and semi-mechanical furnaces, heat efficiency from 0.63 to 3.15 Gcal/hr. Boilers with heat efficiency from 9.6 to 73 Mcal/hr are used for household combustion. Two types of furnaces are applied in heat boilers: for layer and chamber combustion. In layer furnaces fuel is combusted on hand-fired stokers or with the help of a mechanical stoker. ADDITIONS TO THE EMEP/CORINAIR GUIDEBOOK

DEFAULT EMISSION FACTORS TABLES According to 2002 Task Force meetings decisions a few default emission factors tables should be prepared for inclusion into the Guidebook: Primary Lead Production Primary Zinc Production Primary Copper Production Grey Iron Foundries Coke oven furnaces Draft default chapters were prepared and discussed during Combustion and Industry Expert Panel meetings in Ispra (April and November 2002) with participation of this report author. Later the output tables were revised and now their new versions were included into the report with small description (clarification). For their revision own data based upon experience of sources inventory and vast literature data were used. ADDITIONS TO THE EMEP/CORINAIR GUIDEBOOK

OBJECTS AND METHODOLOGY OF HEAVY METALS EMISSION TESTING Sources Testing In 2002 the following HM emission source categories were tested:  solid fuel combustion in household and municipal boilers;  solid fuel combustion in household furnaces;  forest fires;  peatland fires;  agricultural debris burning;  domestic wastes burning.

Experimental work for the HM emission factors evaluation included:  aerosol and vapour HM sampling from off-gases;  fly ash sampling from stack walls and from control equipment;  ash sampling (from bonfires and ashpits);  fuel sampling;  samples preparations;  analytical determination of HM in samples;  data processing.

Heavy Metals Analytical Determination The determination of heavy metal content (Zn, Cu, Cd, Ni, Pb) in samples was carried out on the spectrometer Perkin Elmer AAC 5100 PC\ZL Detection limit without concentration – for flame ionization and graphite furnace accordingly. Detection error – within the limit ± 20%. OBJECTS AND METHODOLOGY OF HEAVY METALS EMISSION TESTING
