Techflow - Bag Filter for Boiler Description

TECHFLOW is one of the leading bag filter manufacturers in India and has been supplying equipment to many industries like Foundry & Steel, Cement, Boilers Flue Gas, Kiln Exhaust, Solids Drying, Mining and Minerals, Glass, Particle Board Manufacturing, Wood-Working and laminates, Air Pollution Control Systems, Hot Gases and Fumes, Coal Handling and many more industries. And TECHFLOW also has tie-ups with many Boiler Manufacturer who buys APCE from TECHFLOW for their Boilers.

To control the emission of wood/coal/lignite fired Boilers it is necessary to have Bag Filter. This Boiler Pollution Control System will limit the SPM level of the emission and if gases(sulphur) are also a constraint then one should go for venturi type wet scrubber in loop after bag filter. We manufacture high quality Bag Filter in Ahmedabad and supply across the globe. Because of our customer centric approach, we are one of the most preferred suppliers. As a reliable manufacturer, offering high quality Bag Filters for boilers.

Basically, boilers are used to generate the steam for the process plants, power plants and various other plants. Boiler will use Gas, Electricity, Oil, Solid Fuels, LPG or Renewable Energy as fuel to generate steam. Out of all the fuels, Solid Fuels are the cheapest and most polluting fuel and are the most used fuel too.

TECHFLOW supplies various equipment for Boiler operations As Following

TECHFLOW Supplies air pollution control equipment or bag filter for following types of solid fired boilers like

These air pollution control systems for boilers are generally supplied to textile plant, chemical plant, power plant, cement plant, process houses, dairy, pharmaceutical, paper, steel plant, sugar mills, power plant and many others.

TECHFLOW Design and supply pulse jet bag filter or aur pollution control system for boilers based on the fuel and requirement of outlet emission. following are two major types of pulse jet bag filter we use to control pollution of boiler

Online Cleaned Pulse Jet Bag Filter

Dust laden air enters the hopper where heavier particles drop out of the air stream. The lighter particles are trapped in the air stream and rise into the filter bags . As the air passes through the filter bags, the dust particles are collected on the outside surface of the filter bags and the cleaned air is exhausted out through the collector. At precise intervals, jets of compressed high-pressure air pass through venturis thru pulse valve and blow pipes, inducing a strong flow of secondary air, briefly reversing the airflow through the bags. This produces an internal shock wave which travels down the length of the bag, causing the bag to pressurize and flex outwards. This allows reversed airflow to dislodge accumulated dust on the outside of the bag where it falls down into a collection hopper. With this method of cleaning, airflow through a row of bags is reversed for only a fraction of a second, resulting in steady state airflow conditions throughout the dust collector. The cleaning operation is controlled by an easily adjusted solid state timer. A Differential Pressure gauge permits optimum regulation of the timer. Pulse durations and pulse intervals can be simply and accurately set at the timer to minimize compressed air consumption.

Off Line Cleaned Pulse Jet Bag Filter

Pulse-jet baghouses can also be compartmentalized. In this case Isolation/Poppet valves located in the clean air plenum are used to stop the flow of dirty air into the compartment. Each compartment can be equipped either with a single pulse valve that supplies compressed air to the group of bags, or have separate pulsing valves that direct pulsing air into the blow pipes above the bag rows in the compartment. During the cleaning cycle the Isolation damper closes, stopping the air flow through the compartment. The pulse valve opens for about 0.2 second, supplying a burst of air into the bags for cleaning. The compartment remains off-line while pulsing process, although this time period can be longer or shorter if desired. The Isolation/poppet valve then automatically reopens, bringing the compartment back on stream. Alternate compartments are cleaned successively until all the bags in the baghouse have been cleaned. This cleaning is called off-line cleaning. It is frequently used on fabric filters installed on Low bulk density product/dust, allowing very thorough bag cleaning while the baghouse continuously achieves very low emission levels.

While this Bag Filter Flue Gas offers reduced levels of particulate emissions it is also easy to operate and maintain. The bag filters are cost-effective and high-quality equipment for flue gas filtration. Since the particles separated by the filter are collected at the bottom of the bag filter it becomes easier to dispose of them. The filter material made by reputed manufacturers is of superior quality and can withstand high temperatures. They are also capable of accommodating a high range of gas flow rates. The equipment and flue gas provides an ulterior filtration of all sized particles and has higher dirt holding capacities. Our experts at TECHFLOW have years of experience in designing air pollution control systems for boiler operations.

Pollution Control Bag Filter is an effective technology of gas steam filtration. It operates by preventing the particle movement. This technology is widely used for boiler cleaning and air pollution reduction worldwide. Bag Filters run at very high temperature, so as a trusted manufacturer of Bag Filter in India, we provide various safety equipments to avoid any damages to bags which are as following.
