The bottom ash system is provided with 'W shape water impounded hopper assembly with seal trough constructed from SS plate. The bottom ash hoppy is provided with outlets with remote operated feed gate, below nach feed gate housing, Clinker Grinder and Jet pump of suitable capacities on dry ash basis are provided. The ash from BA hopper is fed to the clinker grinder and crushed to desired size. The jet pump located below clinker grinder transports the ash in slurry form by using high-pressure (HP) water to the common ash slurry sump provided units. The effective storage capacity of B.A. hopper is considered for several hours. The capacity of Bottom Ash & Economiser Ash collection and adequate headroom is made available to accommodate B.A. nopper equipments within the ground level. The bottom ash hopper assembly consists of refractory lining, inspection window, hopper quenching, tiling overflow and drain connection. Around the top periphery of the BA hopper fabricated SS seal trough with set stops are provided.
This system is mounted fully sealed to the combustion chamber. The negative pressure inside the boiler sucks air in a controlled manner mainly at the top end of this system into the Dry Conveying System. This air travels in counter flow direction along the surface of the ash, which rests on the conveyor belt. This activates a re-burning process of the glowing ash, which reduces the unbumed carbon level and trees up additional thermal energy. Tar is neated up before it enters the combustion chamber and adds additional thermal energy to the steam generating process inside the boiler.
The OSMPPL Materials Handling Submerged Scraper Chain Conveyers (SSC)is used for the continuous removal of fumace bottom ash from boilers and is particularly suitable where headroom is limited. The system is capable of quenching and transporting ash and offers greater energy efficiency compared to hydraulic systems of the same capacity. A double roll crusher feeds the ash either to a slurry disposal system or onto below conveyors for further transfer
The Dome Valve is unique in its ability to close and seal in one action through a static or moving column of material entering the conveying pressure vessel. This feature ensures complete filling of the vessel. Pressure-tight sealing against a pressure differential when handling abrasive materials is achieved with an inflatable elastomeric seal. The fast closing cut off valve incorporates a unique inflatable sealing mechanism. The inflatable seal eritraps particles, thus preventing wear & tear by erasing to the valve seal & prolonged life of dome valve. When in a closed position the inflatable seal arrangement provides a pressure tight seal not allowing compressed air along with fines to escape/leak resulting in energy saving and again wear & tear elimination. These advantages are maintained even through severe application conditions for abrasion, temperature, and high pressure. The operating efficiency of all OSMPPL Material Handing Systems relies upon the Dome Valve, currently installed at over 10.000 applications nationwide. Every OSMPPL system is fitted with the Dome Valve lo ensure operation reliability and system efficiency
Several inflatable seals are available depending on the application. The choice includes a white food quality seal as well as those specially formulated for high temperature and/or other hostile applications. The unique closing and sealing action of the Dome Valive enables continuous reliable operation where conventional valves fail to perform,

Terminal box is used at the very last reception point on a conveying line. It is designed to have increased durability than a simple pipe termination; with a design that accommodates easy deflector plate replacement instead of a complete terminal box or pipe terminationi replacement. These form the termination of the pneumatic conveying transfer pipe and secure entry of the material into the chosen reception hopper
Ash conditioners (also called ash unsolders) are key to the ash handling system as they minimize the environmental impact of ash handling and unloading. We offer Single / Double Rotary Paddle type ash Conditioners of various capacities. The paddles provided on the slow rotation shaft mixes the dust discharged from the silo with controlled rate spray water feed to uniformly form earth-moist state where the ash is dust-free, Water spray feed rate is adjusted with the control valves. The conveying action provided by the rotating paddles provide a continuous flow of uniformly mixed ash with no excess water or dusting. These complete ash conditioner assemblies include motor and drive and feature abrasion resistant paddles reinforced with SS nozzles for long service life.

HCSD System comprises of controlled and monitored feeding systern for fly ash and bottom ash followed by a homogenous mbing in an adequately designed Agitator Retention Tank (ART). Proper monitoring of the slurry properties is the key to the success of the system. HCSD pumpransports the highly concentrated slurry from the ART to the ash disposal area through carbon steel pipelines. These pumps have the mechanism for capacity variation depending on the characteristics of the slurry. The de-blocking facility is also considered either by the HCSD pump itself or through a separate water pump.
OSMPPL offers Bag filter with "ON line pulse jet design. Bag filter has compartments. Contaminated gasses enter from central inlet gully and distributes evenly in the compartment. Fitered gasses pass through bags into clean air plenum & then out of collector free of dust. The dust deposited un the bags is cleaned by a burst of metered compressed air injected through venturi tubes. The intensity & pressure of compressed air is controlled by a quick acting plot operated diaphragm valves resulting in an ideal cleaning action. As the gasses enter the bag house, their velocity drops down allowing the coarser particles to fall into the hopper Fine particles are airborne to the feit media. Gasses pass through the bags depositing the dust on the outside of the bag Dust is cofected in Bag filter hopper and discharges Through the RAV

Pipe conveyors are an environment-friendly solution for conveying bulk material with zero spillage with the ability to cover terrain difficult to negotiate by conventional conveyors. Pipe conveyors are being used to carry coal, limestone, sinter, BF dust, in lengths varying from 48 m to 7,500m. Pipe conveyors are similar to a conventional belt conveyor at the material receiving area and discharge area. Thereafter the flat belt is slowly shaped to trough belt through transition and carrying idlers. At the end of the loading zone, the conveyor belt gradually takes on a pipe formation with the help of variable offset rollers, finger rollers and pipe formingidlers. In the straight portion of a pipe conveyor, the bottom three rollers at the carrying side support the belt and material load whereas the top three rollers maintain the belt in its pipe shape. At the horizontal and vertical curved sections, rollers surrounding the belt support the load depending on the direction of the resultant force. The same applies to the bottom or retum belt side of the pipe conveyor which may be utilized to transport the second material thereby reducing capital and operating cost.
We are leading manufacturer of the equipment. Two-stage evaporative coolers do not produce humidity levels as high as that produced by traditional single-stage evaporative coolers. In the first stage of a two-stage cooler, warm air is pre-cooled indirectly without adding humidity (by passing inside a heat exchanger that is cooled by evaporation on the outside). The result, according to the manufacturer, is cool air with a relative humidity between 50 and 70 percent, depending on the climate, compared to a traditional system that produces about 80 percent relative humidity air. The ventilation equipment is available from 2000 m3/hr to 3,00,000 m3/hr capacity and can be supplied for various applications namely, MCC rooms, ventilation for works, tunnel ventilation, ventilation for basement, crusher house, exhaust fan system, ventilation system for complete thermal power station etc. Application: • MCC rooms • Industrial works • Tunnel ventilation Basements • Crusher houses • Exhaust fan systems • Thermal power station
