Air Duct Performance & Air Quality Control

This report focuses on improving the air performance and air quality of the Bombardier Global 7500. A test rig is designed and built, with the intentions of simulating the inlet ducting of the Global 7500. The performance of the test rig has been measured, and the ducting is prepared for testing. Preparations have been made to test the effect that various air outlets have on the performance of the ducting. The temperature can vary throughout the cabin, causing discomfort for passengers, it is possible that the inlet ducting is responsible for this. Additionally, the effect of numerous air pollutants has been explored and a focus has been made to test particulate matter and carbon monoxide. The Honeywell HPM Series and the Adafruit MiCS5524 have been suggested for detecting particulate matter and carbon monoxide respectively. The ducting designed can be used for various air performance and air quality research in the future.

“Military Parade Blue Skies” in Beijing: Decisive Influence of Meteorological Factors on Transport Channel and Atmospheric Pollutant Concentration Level

The severity of high atmospheric pollution has been a major social problem in northern China. To improve the air quality in the Beijing–Tianjin–Hebei (BTH) region and guarantee a suitable environment during the military parade and other celebrating activities for the 70th anniversary of the victory for anti-Fascist Warcraft in the year 2015, a series of strict air quality control policies were carried out. To analyze the reduction extents of PM2.5 and organic matter components during the control period and to examine the meteorological conditions in this region and their decisive influence on the air quality, PM2.5 samples were collected and the Lagrangian particle dispersion model FLEXPART was performed to calculate potential source locations within the BTH region. PM2.5, organic carbon (OC), elementary carbon (EC), and three species types were specifically analyzed. Although the results showed that PM2.5, OC, and EC reduced by 64.55%, 48.74%, and 60.75% during the control period, the air mass transport patterns showed great difference at certain periods, which altered the dominant transport direction of air mass and the potential source region of pollutants and organic matters. This alteration completely changed major atmospheric pollutants sources contribution and caused huge concentration changes. Parallel cases also showed that meteorological conditions could avoid massive atmospheric transported from a major emission source region to a receptor site. The meteorological conditions changed the main contribution source region in control and non-control periods and proved the air quality control measures were less necessary in some southern Hebei cities during special events periods.

Risk and Impact Control of PM2.5 and SO2 Exposure of Power Plant to Communities (A Case Study in the Steam Power Plant Babelan Bekasi)

Introduction: Coal consumption for electrical energy at Steam Power Plant increase often with economic and population growth. Burning coal produces harmful pollutants such as PM2.5 and SO2 affecting public health problems and decline in social and economic conditions. Therefore, implement the strategies are needed to reduce risks and long-term impacts on the environment. The research aimed to analyze the risk and impact of air pollutants exposure and develop control strategies. Methods: This study used the methods of environmental health risk analysis, analysis of the level of understanding and perception, cost of illness analysis, and Strength, Weakness, Opportunities, and Threats analysis, Data obtained by survey, interviews using questionnaire instrument to 293 respondents, five experts to determine risk control strategies and the secondary data from Environmental Agency of Bekasi Regency. Results and Discussion: The result showed that most risk is 13-55 years old, and people who live less than two square kilometres from the power plant. The level of public understanding and perception resulted in moderate criteria. The average cost of illness is 14.51% of the average monthly income of each person. The recommendation strategies are implemented regulations of power plant location, providing guidelines for environmental controlling, air quality control regularly, tightening air quality standards, prioritizing air pollution control budgets, providing green space, implementing clean energy and renewable energy, and building capacity air quality control. Conclusion: The production of electrical energy on Steam Power Plant had an air pollution impact such as health problems, decreased income, and social disruption. Air pollution control includes structural and nonstructural strategies from internal and external Steam Power Plant to provide environmentally friendly energy production for the communities.
