Pulse Jet Bag Filter
The Bag House/Bag Filter is generic name of Air Pollution Control Equipment. It is designed around the use of engineered fabric, filter tubes, envelopes or cartridges in capturing dust, separating dust or filtration process. AIL provides reliable and highly efficient Bag Filters and Bag House systems.

The dust laden gas enters through inlet nozzle and spreads all over the entire cross section of the bag filter. The gas moves up & passes through the bags, enters the clean air plenum through the top open end of the bags. During the passage of the gases through the fabric, the dust is retained on the outside surface of the bags. As the filtration proceeds the thickness of the dust layer on the fabric surface increases resulting in increase in pressure drop across the fabric. This necessitates the cleaning of the bags. Since the air flow is from outside to inside, the bags tend to collapse and are held by the wire cages, whose shape they acquire. The compressed air passing through the solenoid valves injects air at very high velocity for a short duration. This produces a shock wave causing the bag to expand and dislodging the dust cake which falls into the hopper. This unit is generally meant to operate with a pressure differential of 100-125 mmWG.

Cyclone Dust Collector is a system used to enhance the quality of air released from industrial and commercial processes by collecting dustand other impurities from air or gas. Designed to handle high-volume dust loads, a dust collector system consists of a blower, dust filter, a filter-cleaning system, and a dust receptacle or dust removal system. It is distinguished from air purifiers, which use disposable filters to remove dust.
Multiple-cyclone separators consist of a number of small-diameter cyclones, operating in parallel and having a common gas inlet and outlet, as shown in the figure, and operate on the same principle as single cyclone separatorsâ??creating an outer downward vortex and an ascending inner vortex.

Multiple-cyclone separators remove more dust than single cyclone separators because the individual cyclones have a greater length and smaller diameter. The longer length provides longer residence time while the smaller diameter creates greater centrifugal force. These two factors result in better separation of dust particulates. The pressure drop of multiple-cyclone separators collectors is higher than that of single-cyclone separators, requiring more energy to clean the same amount of air. A single-chamber cyclone separator of the same volume is more economical, but doesn't remove as much dust.

Cyclone separators are found in all types of power and industrial applications, including pulp and paper plants, cement plants, steel mills, petroleum coke plants, metallurgical plants, saw mills and other kinds of facilities that process dust.

APPLICATION OF SK-HB K-SILICATE MORTAR :

* K-SILICATE is used for jointing Acid Resisting brick in construction of vessels in suited for construction of fume chambers and stacks handling hot, dry Acid fumes and vapors.
It is also used for jointing chemical resisting stoneware pipes.
K-SILICATE cement is good bedding material for Acid â?? Resisting bricks and tiles.
The concrete surface needed protection should be dryed, clean and rough.
The bricks or tiles will be set with K-SILICATE cement over concrete surface applied with a suitable an impermeable interliner.

When Bedding and Jointing Materials are the same.
On the treated surface bricks or tiles are bedded to a thickness of about 6 mm and tamp gently with a wooden piece till the paste squeezes out of joints.
The paste that is squeezed out of the joint should be removed by trowel with good finishing. After the mortar of the joint is dryed treat the joints with 20% Hydrochloric Acid Solution by means of brush. A.R.lining should be always in contact with Acid and not with water.
Concrete subtract like Floor, Wall, tanks and similar surface should be protected with a membrane of Bitrok Mastic or compound steel tanks should be protected with rubber or PVC subjected to chemical conditions and temperature of chemical media. The Brick lining is recommended over the protective layer of Bitrok Mastic.
When Bedding and Jointing Materials are Different.
Spread the silicate type mortar about 6 to 8 mm thick on the back of the tile or brick. Press the tile on the bed leaving required space for joints between tiles for bricks. After the bedding mortar is set, fill Mp the joints with specified cement.PRODUCT DATA SHEET FOR SK-HB ( K-SILICATE) MORTAR
A general purpose cement for acid conditions Resistant to High & medium concentrations of most of the common organic and inorganic acids except Hydroflouric acid. Recommended where the concentration of the acid is high suitable for high temperature. Unsuited to aqueous solutions, alkaline conditions.

PREPARATIONS OF MORTAR :
* Measure 1 part by weight of K-SILICATE solution into a suitable mixing pan.

* Add slowly and gradually 3 parts by weight K-SILICATE mortar and mix thoroughly to form a smooth mortar.

* In hot season very large batches of mortar will become stiff quite rapidly therefore small batches, not exceeding 4 to 8 kgs. Will be prepared.

* The cement mortar will be used before it starts setting.

* PHOSCAST
Phoscast : Phosphate Bonded Castables

* PURPOSE
customers using FBC boilers (Particularly underbed feed FBC boilers) for the protection of inbed coils against erosion potential by applying highly abrasive resistant refractory on inbed coils above fuel feed system.

BACKGROUND

* Two of such actions are providing special alloy studs on inbed coils and applying highly abrasive resistant refractory on the outer bottom loops of inbed Coils which are above the fuel feed nozzles.

* GANESHAS has taken number of approaches to identify the key factors affecting erosion rates with an objective to enhance the life of inbed tubes as well as implementing the corrective action to reduce the erosion rates.
Phosphate coatings are often used to protect steel parts against rusting and other types of corrosion

* Erosion of inbed coils in fluid bed combustor is unavoidable phenomenon however the rate of metal wastage and thus the life of tubes depends on various factors like ash & fuel properties, design of Combustor / feeding system, flue gas velocities operating conditions etc. It has been also observed that maximum erosion prone inbed coils are those which come above fuel feed nozzles and an area of approximately 1 to 1.5 mts around fuel feed systems are badly affected.

APPLICATION
Phoscast-90 XR can be applied by ramming with wooden mallet having adequately large head @" dia x 5" length x 10â?? Jong handle). The desired lining or repair thickness is built up in several courses while ramming the mass to uniform thickness. Phoscast refractory should never be trawled to obtain smooth surface; ramming only should finish surface. Any excess mass is to be sliced off with trowel edge and then finished by ramming again for bed coil. Tube application of AFBC boiler, the material pasty mass should be finger pressed into the studs of the tube with maximum force. Finish should be given by pressing the hand palm against material applied, using surgical type thin rubber hand gloves.

Acid / Alkali Resistant Tiles/Bricks

* Our Acid proof tiles, Acid alkali resistant tiles, Chemical resistant tiles are fully vitrified tiles which are manufactured using special non ferrous clay, processed at extremely high temperatures this process causes the raw materials to fuse and form a compact mass with an extremely low water absorption of less than 0.5% resulting in the formation of a very strong body with a flexural strength of 38 N/mm2, solid through color fade proof with a very hard surface Mohs hardness of 7.

Conventional tanks (concrete or mild steel) are prone to aging, wear and corrosion.
Concrete can crack when exposed to erosion and natural disasters, leading to water
contamination and leakage â?? and usually canâ??t be repaired. MS rusts easily and its also
easy heat conductor.
FRP â?? Fiber Reinforced Polymer is a strong but light weight glass fiber reinforced plastic
composite used in the aerospace, automotive, marine and construction industries. It has
a high-strength to weight ratio, an extremely long lifespan, and easy to maintain as well as
heat resistant.
FRP sectional panel tanks provides all types of advantages which other liquid storage
methods doesnâ??t. These tanks are DURABLE, LEAK-FREE, COST-EFFECTIVE OVER LIFECYCLE as well as EASY TO INSTALL, RECONFIGURE AND RELOCATE. This is an ideal option
for a wide range of usage including potable water storage, food and factory production,
commercial mining, fire protection, industrial liquids, rainwater harvesting, seawater
storage, and any other kind of liquid and granular storages.
