Stack air emission assessment is a process to identify the harmful exhaust gases. Basically, gases are released into the air from boiler stack, chimneys or Diesel Generator set stack etc. from various industries after the incineration process i.e. method to remove or burn the harmful gases before releasing to the environment.
Stack air emission assessment is important because Stacks from boilers and industrial processes will carry pollutants such as CO2, CO, SOx, NOx, particles, solvents, and other dusts and gases. These can have a detrimental effect on local air quality and for this reason, such emissions are often regulated. By doing stack air emission assessment, we can monitor whether the emissions are below the limits.
