- Description
- PRE-SOLICITATION NOTICE for the United States Environmental Protection Agency (U.S. EPA) Cincinnati Procurement Operations Division (CPOD) and Office of Research and Development (ORD), National Risk Management Research Laboratory (NRMRL), Air Pollution Prevention and Control Division (APPCD). The EPA/ORD/NRMRL/APPCD has a requirement for a continuous emission gas analyzer to be used in the Open Burn Test Facility (OBTF) at EPA's NRMRL laboratories in Research Triangle Park, North Carolina. The OBTF is used to conduct research on the emissions from open burning of various fuels, specifically biomass and waste fuels. Pollutant emissions are sampled using various methods adopted from both open air and stack sampling methods. Numerous instruments are employed in this study to capture the varied emission components. Gaseous emissions are measured in real-time for carbon dioxide (CO2), carbon monoxide (CO), methane (CH4), total hydrocarbons (THCs), black carbon (BC), and fine particulate matter. Aerosols of particulate matter with aerodynamic diameter ≤ 2.5 ?m (PM2.5) and varied forms of carbon (Black, Organic, Elemental) are measured in real-time for size distribution and concentration. Gravimetric analysis is performed on the filter samples of aerosols and o rganic carbon (OC), elemental carbon (EC) and black carbon (BC). EPA requires continuous emission gas analyzers to measure total hydrocarbons (THC) and methane (CH4) (both or switchable), carbon monoxide (CO), and carbon dioxide (CO2). The instruments will be incorporated into an existing but old (>15 years) continuous emissions monitoring (CEM) system to expand the research capabilities and improve the data quality of the OBTF research testing. The performance and technical requirements for the individual analyzers are based on the emissions measured from current and previous OBTF testing accomplished to date. Emissions from the OBTF burns are captured with in-facility open air samplers or in a stainless steel duct system. Dilution air, supplied to the OBTF via a forced draft fan and induced draft fan, maintains the interior OBTF oxygen concentration close to ambient, ensuring that open air burn conditions are simulated well. The OBTF emission sample is provided via a heated (120 ?C) 1/4" ID Teflon sampling line, filter and pump. The pump provides excess flow to support multiple instruments at a pressure of 5 psi. Excess flow is provided to ensure adequate sample supply and vented to atmosphere. The gas stream goes through a water knockout system to remove excess moisture. This sample flow then goes to a common manifold and is flow regulated (rotameters) to the existing CEMS at rates specified by the instrument manufacturer. This gas source is maintained at a 5 psi pressure by controlling an excess flow rate. Particulate filters are in-line with the sample gas stream prior to each instrument. The oxygen concentration is near to ambient (~20.9%) at all times due to the flowrate of ambient dilution air involved. The enclosed OBTF experiences about one complete air exchange every 60-90 seconds. The following table shows the expected concentrations associated with typical test conditions. CEMs will be required to meet these concentrations. Note, actual measured concentrations include values less than and greater than those presented.
