Particulate matter emission reduction in small- and medium-scale biomass boilers equipped with flue gas condensers: Field measurements
نویسندگان
چکیده
Flue Gas Condensers (FGC) are used to increase the thermal output of biomass boilers. This reduces emissions per unit produced energy but furthermore, fine dust particles will be collected in condenser. These condensers therefore have a double effect on specific particulate matter emissions. In addition mechanisms that cause particle capture such as thermophoresis and diffusiophoresis, other agglomeration or condensation growth also influence size emitted particles. Due combination these mechanisms, efficiency depends size. A range presenting lower efficiency, called penetration window, is generally observed. Measurements 5 MWth boiler showed this window 0.07–0.49 μm where reduced by around 20%. an 18 kWth 0.04–0.49 can even negative window. For medium-scale boiler, condenser overall 64% number 62% mass m3, 70% 69% MJ. small-scale 4% 50% 14% 55%

Particulate Matter Emission Factors for Biomass Combustion
Emission factor is a relative measure and can be used to estimate emissions from multiple sources of air pollution. For this reason, data from literature on particulate matter emission factors from different types of biomass were evaluated in this paper. Initially, the main sources of particles were described, as well as relevant concepts associated with particle measurements. In addition, arti...
متن کاملMeasurements and Modeling of Flue Height Influence on Air Pollution Emissions and Thermal Efficiency of Natural Draught Gas Fired Boilers
This paper presents and analyses results from experimental and CFD work undertaken on a 24 kW domestic natural-draught gas fired boiler. The effect of chimney height on boiler flue gases is being considered to address the need for increasing concern over environmental safety as well as saving of energy. A multi-component analysis computer (DELTA 2000 CD) is used to analyze the flue gases. 3D nu...
متن کاملSurvey on Measurements and Emission Factors on Particulate Matter from Biomass Combustion in Iea Countries
Since biomass combustion is related to high emissions of particulate matter (PM), the International Energy Agency (IEA) Bioenergy Task 32 is promoting the implementation of technical measures for PM reduction. As a basis to set priorities and as a guideline for future regulations, emission factors from different types of combustion are of interest. The target of the present study is to collect ...
