Flue gas treatment, a process designed to reduce the amount of pollutants emitted from the burning of fossil fuels at an industrial facility, a power plant, or another source. Flue gas the emitted material produced when fossil fuels such as coal, oil, natural gas, or wood are burned for heat or power—may contain pollutants such as particulates, sulfur dioxide, mercury, and carbon dioxide. Most flue gas, however, consists of nitrogen oxides. If left untreated, flue gas from power plants, industrial facilities, and other sources can substantially affect local and regional air quality.

Under many national-level clean-air regulations, power plants and other facilities are required to use flue gas treatments to reduce the amount of emitted pollutants. For such approaches, GPT-India suppliys High quality Dust extraction system comprising of Cyclone dust collector followed by Pulse Jet Bag Filter. In some cases it can be further followed by a Wet Scrubber which can successfully remove 90 percent or more of certain pollutants. However, they can be very costly to install and operate, and requirements for flue gas treatment frequently provoke complex legal battles. Treatments vary widely from one plant to another, and some countries have far-stricter requirements than others. Emissions from utilities and industries in countries with less-stringent pollution laws are a concern for environmentalists.

Treatment process

At plants that emit a number of pollutants, flue gas may go through a series of devices for cleaning. Flue gas treatment has achieved the greatest success in reducing particulate matter, nitrogen oxides, and sulfur dioxide. In a typical treatment process, the gas is first sent to a cyclone Dust collector where coarse particles get saparated which is then followed by a Pulse Jet fabric filters where fine particles are trapped. Particulate removal is an essential part of the process, because particulates released into the atmosphere can affect the respiratory systems of people and animals, reduce visibility, and influence climate. Depending on such factors as the size of the particles and the design of the Dust Extraction system, this treatment can remove 99 percent of particulate matter.

We are engaged in offering a wide range of Bag Filter Systems to our clients. Our range of all products is widely appreciated by our clients.

A Bag Filter is a type of Industrial Air pollution control system that uses a series of filter bags to remove suspended particulate matter from gas streams. The filter bags are made of a different type of filter media, such as polyester, nylon, woven & non woven needle felt filter bags or glass fiber, that has small pores that trap the particles on its surface. The gas stream flows through these filter bags, and the particles are captured on the surface of the bags. The bags are then cleaned periodically through compressed air blast to remove the captured particles.

In industries, we use Pulse Jet Bag filter to keep the air clean. This is especially important when we are dealing with Boilers. The bags are cleaned to get rid of the trapped particles. This way, the bag filter and the boiler work together to make sure that the ambient & atmospheric air stays clean and safe. 

Bag filters are used in a variety of industries, including:

• Power generation
• Cement factories
• Steel industries
• Metal working
• Chemical manufacturing
• Food processing
• Pharmaceutical manufacturing
• Dstilleries & Breweries
• Rubber industries
• Waste Recycling industries
• Tyre industries
• Wood industries
• Plywood industries

Operations related to the extraction of mineral ore such as blasting, transportation, grinding, and crushing can release large amounts of dust into the atmosphere. This is particularly true in a crusher plant where the demolition of stones, an operation that generates vast amounts of dust, is a daily procedure.

Dust can generate a series of problems for industrial operations. Not only can dust cause health problems, but it can also reduce the productivity of a mining site by limiting visibility and increasing wear-and-tear on equipment. 

Crusher dust is a type of fine dust, which contains very small 0-5mm aggregate particles as well as sand. It is formed as a by-product from mining operations and is often recycled for different applications such as construction. 

Whenever rocks are crushed by rock crushing equipment, tiny PM 1, PM 2.5 and PM 10 dust particles spread through the air. This by-product of rock crushing may cause harm to the health of workers and nearby communities and damage the durability of equipment, leading to bearing failure, lubricant contamination, and increased risk of fire autoignition.

Particles coming from high compressive strength rocks (hardness), with a higher mosh index and angularity (sharp edges) cause the greatest damages, such as silica, quartz and diamond dust. 

Silicon dioxide, also known as silica, is a chemical compound commonly found in quartz. Silica normally presents itself in a crystallized form, and it is a component of sand in various parts of the world. Industrial uses of silica include the manufacturing of microelectronics and structural materials. Some living organisms, such as grass, use silica as a defense mechanism to drive off herbivores.

Breathing dust particles from crystalline silica can have scathing effects on a person’s health. Airborne dust can stay lodged inside the lungs, causing inflammation and scarring on lung tissue. This condition is known as silicosis and can result in permanent lung damage or even the death of the patient. 

Chronic silicosis can occur after periodic exposure to silica dust, but exposure to large amounts of dust can drastically hasten the development of the condition. Even after exposure to dust is discontinued, silica dust particles can remain in the lungs for prolonged periods of time. 

Symptoms of silicosis include: 

• Cough
• Fatigue
• Shortness of breath
• Chest pain

Silica dust from stone crushing can be a major factor in a person developing silicosis, leading professionals to catalog it as an occupational lung disease. Complications from developing silicosis can also cause patients to develop more serious diseases. 

Examples of other serious diseases caused by silica and other airborne dust exposure include:

• Tuberculosis
• Lung Cancer
• Chronic Obstructive Pulmonary Disease (COPD)
• Kidney Disease
• GPT Dust Collectors can monitor airborne dust levels by using state-of-the-art measurement technologies. Alongside solid methodologies supported by years of research and development, the Pulse Jet Dust collector technology can be used to assess dust levels in the atmosphere under different environmental conditions. Using this data, you can determine which extraction method can best ensure mine safety while guaranteeing competitive mining operations.

GPT Centralised Dust extraction systems are highly efficient in extraction of fine airborne dust emerging out of several cutting machines in a shop floor so that all the airborne dust can be collected at a single point
