Modeling Arsenic Partitioning in Coal-Fired Power Plants

post-combustion region of a coal- red boiler as a function of gas residence time. The purpose of the model is to calculate the partitioning of arsenic between the vapor phase from volatilization, and arsenic on the ash particles due to surface reaction andor condensation at temperatures characteristic of

Modeling arsenic partitioning in coal-fired power plants

Less than 3% of the arsenic remains in the boiler slag and 3% is captured by the desulfurization system. Another 1% is captured by wet precipitators. The remaining arsenic is emitted from the stack.

What to do if your drinking water contains arsenic

Jun 28, 20140183;32;Even low doses of arsenic trigger cancer in mice, study finds. Arsenic is an element found in the Earth's crust, and it finds its way into food, water, soil and air. In 2000, the U.S. Environmental Protection Agency considered tightening the drinking water standard for arsenic — then at 50 parts per billion — to as low as 3 ppb.

Safety and Health Topics Arsenic - Hazard Recognition

Arsenic exposure in the workplace occurs through inhalation, ingestion, dermal or eye contact. Chronic exposure to arsenic leads to to distinct skin diseases, such as arsenical keratinosis, which is characterized by excessive formation of scaly skin on the palms and soles; darkened patches of skin; wart formation; skin lesions; acne; and increased risk of skin cancers.

Arsenic and Drinking Water from Private Wells Wells

Once released, arsenic remains in the environment for a long time. Arsenic is removed from the air by rain, snow, and gradual settling. Once on the ground or in surface water, arsenic can slowly enter ground water. High arsenic levels in private wells may come from certain arsenic containing fertilizers used in the past or industrial waste.

1.3 Fuel Oil Combustion

A cast iron boiler is one in which combustion gases rise through a vertical heat exchanger and out through an exhaust duct. Water in the heat exchanger tubes is heated as it moves upward through the tubes. Cast iron boilers produce low pressure steam or hot water, and generally burn oil or natural gas.
