550,METHOD 5H ) DETERMINATION OF PARTICULATE MATTER EMISSIONS,FROM WOOD HEATERS FROM A STACK LOCATION,NOTE: This method does not include all of the,specifications (e.g., equipment and supplies) and procedures,(e.g., sampling and analytical) essential to its,performance. Some material is incorporated by reference,from other methods in this part. Therefore, to obtain,reliable results, persons using this method should have a,thorough knowledge of at least the following additional test,methods: Method 2, Method 3, Method 5, Method 5G, Method 6,Method 6C, Method 16A, and Method 28.,1.0 Scope and Application.,1.1 Analyte. Particulate matter (PM). No CAS number,assigned.,1.2 Applicability. This method is applicable for the,determination of PM and condensible emissions from wood,heaters.,1.3 Data Quality Objectives. Adherence to the,requirements of this method will enhance the quality of the,data obtained from air pollutant sampling methods.,2.0 Summary of Method.,2.1 Particulate matter is withdrawn proportionally,from the wood heater exhaust and is collected on two glass,fiber filters separated by impingers immersed in an ice,water bath. The first filter is maintained at a temperature,551,of no greater than 120 EC (248 EF). The second filter and,the impinger system are cooled such that the temperature of,the gas exiting the second filter is no greater than 20 EC,(68 EF). The particulate mass collected in the probe, on the,filters, and in the impingers is determined gravimetrically,after the removal of uncombined water.,3.0 Definitions.,Same as in Method 6C, Section 3.0.,4.0 Interferences. [Reserved],5.0 Safety.,5.1 Disclaimer. This method may involve hazardous,materials, operations, and equipment. This test method may,not address all of the safety problems associated with its,use. It is the responsibility of the user of this test,method to establish appropriate safety and health practices,and to determine the applicability of regulatory limitations,prior to performing this test method.,6.0 Equipment and Supplies.,6.1 Sample Collection. The following items are,required for sample collection:,6.1.1 Sampling Train. The sampling train,configuration is shown in Figure 5H-1. Same as Method 5,Section 6.1.1, with the exception of the following:,552,6.1.1.1 Probe Nozzle. The nozzle is optional; a,straight sampling probe without a nozzle is an acceptable,alternative.,6.1.1.2 Probe Liner. Same as Method 5, Section,6.1.1.2, except that the maximum length of the sample probe,shall be 0.6 m (2 ft) and probe heating is optional.,6.1.1.3 Filter Holders. Two each of borosilicate,glass, with a glass frit or stainless steel filter support,and a silicone rubber, Teflon, or Viton gasket. The holder,design shall provide a positive seal against leakage from,the outside or around the filter. The front filter holder,shall be attached immediately at the outlet of the probe and,prior to the first impinger. The second filter holder shall,be attached on the outlet of the third impinger and prior to,the inlet of the fourth (silica gel) impinger.,6.1.2 Barometer. Same as Method 5, Section 6.2.,6.1.3 Stack Gas Flow Rate Measurement System. A,schematic of an example test system is shown in Figure 5H-2.,The flow rate measurement system consists of the following,components:,6.1.3.1 Sample Probe. A glass or stainless steel,sampling probe.,6.1.3.2 Gas Conditioning System. A high density,filter to remove particulate matter and a condenser capable,of lowering the dew point of the gas to less than 5 EC (40,553,EF). Desiccant, such as Drierite, may be used to dry the,sample gas. Do not use silica gel.,6.1.3.3 Pump. An inert (e.g., Teflon or stainless,steel heads) sampling pump capable of delivering more than,the total amount of sample required in the manufacturer's,instructions for the individual instruments. A means of,controlling the analyzer flow rate and a device for,determining proper sample flow rate (e.g., precision,rotameter, pressure gauge downstream of all flow controls),shall be provided at the analyzer. The requirements for,measuring and controlling the analyzer flow rate are not,applicable if data are presented that demonstrate that the,analyzer is insensitive to flow variations over the range,encountered during the test.,6.1.3.4 Carbon Monoxide (CO) Analyzer. Any analyzer,capable of providing a measure of CO in the range of 0 to 10,percent by volume at least once every 10 minutes.,6.1.3.5 Carbon Dioxide (CO2) Analyzer. Any analyzer,capable of providing a measure of CO2 in the range of 0 to,25 percent by volume at least once every 10 minutes.,NOTE: Analyzers with ranges less than those specified,above may be……
