Relationship between Energy Consumption for chalk and brick plants and environmental pollutants emitted by their furnace''s stack

Furnaces as a major process of manufacturing brick and chalk are considered as one of the major sources of greenhouse gases. This study aimed to investigate the relationship between energy consumption of the furnaces of brick and chalk and environmental pollutant emissions in the city of Qom.
This descriptive study was conducted of year 2012-2015. General information and entrance permit were acquired by the respective unions in the city of Qom. Ten field visits randomly chosen from either chalk and brick manufacturers were conducted. In addition, further information regarding the energy consumptions from electricity and gas companies was obtained. The amount pollutants produced from the energy consumption were calculated by using software that available on the website: http//www.abraxasenergy.com/emissions.
The calculated emission of pollutants such as: carbon dioxide, nitrogen compounds, carbon monoxide, volatile organic compounds, Nitrous oxide, lead, particulates, sulfur dioxide, cadmium, mercury were 1001000, 1296.82, 185.7, 41.68, 16.69, 15.19, 14.42, 4.84, 2.4 and 0.316 kg/month, respectively.
Based on the level of pollutants which was higher than comparable industries, strategies such as: rationing fuel, forming an environmental monitoring committee and more efficient control of combustion and burner’s maintenance and application of air purification techniques for pollutants prior to their release through furnaces’ stack was recommended.
