AP-42, CH 11.19.1: Sand And Gravel Processing
To estimate emissions from fugitive sources, refer to AP-42 Chapter 13, "Miscellaneous Sources". The emission factors for industrial sand storage and screening presented in Table 11.19.1-1 are not recommended as surrogates for construction sand and gravel processing, because they are based on emissions from dried sand and

TOTAL PARTICULATE EMISSION FACTOR: Approximately 0.8 kg particulate/Mg bagasse charged to boiler. This factor is derived from AP-42, Section 1.8, 4/77, which states that the particulate emission factor from an uncontrolled bagasse-fired boiler is 8 kg/Mg and that wet scrubbers typically provide 90% particulate control.
Simultaneous evaluation of wind flow and dust emissions from conveyor
Fig. 1 shows the test zone with a blower system (1) of a 5 kW fan and a duct 300 mm in diameter, a conveyor belt (2) 5.3 m in length and 1 m in width and particulate material (3). The air is expulsed at an average velocity of 12.9 m/s, causing an ultrafine coal particle suspension from the previously dusted conveyor belt surface.
