AP42, Compilation of Air Pollutant Emissions Factors, has been published since 1972 as the primary compilation of EPA's emissions factor information. It contains emissions factors and process information for more than 200 air pollution source categories. A source category is a specific industry sector or group of similar emitting sources.
Emissions from the rockcrushing equipment were calculated using emission factors from AP42 Section ··crushed Stone Processing and Pulverized Mineral Processing," August 2004. The plant will be powered by diesel engine, however it meets the definition of nonroad engine as

istics and process parameters. Emission factors are key inputs to estimate emissions. Experiments were conducted to study the effect of blast pressure, abrasive feed rate, and initial surface contamination on total PM (TPM) emission factors for coal slag. Rusted and painted mild steel surfaces were used as base plates. Blasting was carried

May 31, 2017· Crushing Emission Factor is utilized as a conservative estimate because there is no Primary Crushing Emission Factor. Additionally, the use of AP42 Chapter Controlled Emission Factors is allowed as described in the B AP42 Chapter Emission Factor Decision Tree. Finally, multipliers for PM are based on AP42 Chapter
Blast furnace slag aggregate comes in two forms: Air cooled blast furnace slag, results when molten slag from a blast furnace slag cools slowly by ambient air (as opposed to rapid quenching), and is processed through a screening and crushing plant for use principally as a construction aggregate. Air cooled slag is not cementitious.
An emission factor is the relationship between the amount of pollution produced and the amount of raw material processed or number of product units produced (for example, lb/MMBtu, lb/ton, etc.). Emission factors can be AP42 factors, manufacturer specifications, and/or stack test data.

Dec 01, 2013· When the molten slag is projected outwards from the cup, the air is blown from the nozzles to crush the slag. Therefore, the molten slag is essentially granulated by combined actions of a rotating cup and air blast. The effects of rotor speed, slag viscosity and gas flow rate on the size of slag particles were analyzed. The results showed that: (1)
