Dust load in vicinity of boiler-house plants fired with different fuels: case study in Tomsk Oblast

摘要

Study of solid airborne particles emissions from rural boiler-house plants are insufficient. The paper presents the resultsof comparative analysis of dust pollution in vicinity of rural boiler-house plants in Tomsk Oblast different in parametersand fuel type (coal, gas, oil, wood) based on the study of snow cover. The results showed that value of dust load incomparison of background value in vicinity of studied coal-fired houses were different and depended on fuelconsumption rate, presence of dust and gas catchment system, coal depository and vehicle park. The maximum value ofdust load is found in vicinity of coal-fired boiler-house plants, where it increases the background from 2 to 16 times. Invicinity of other boiler-house plants dust load is at the background level. In vicinity of different coal-fired boiler-houseplants the dust load depends on the fuel consumption, effectiveness of dust and gas collection, availability of outdoorcoal storage and vehicle fleet. It is shown that natural gas and wood are the most environmentally friendly fuel from thestandpoint of particulate matter emissions.
