Very often, the motive fluid is steam and the device is called a "steam jet ejector." Basic ejector components are the steam chest, nozzle, suction, throat, diffuser and they discharge (Fig. 1). The two major functions of ejectors are as follows:
Jet Pumps and Hydro Ejector are designed for bottom ash handling system, mill rejects handling, pyrites and other low capacity applications. The water powered jet pumps transport a mixture of water and solid, granular material through a transport pipeline.
Macawber Beekay's product profile includes Jet Pumping System for intermittent removal of bottom ash collected at furnace bottom of PF type boilers. System comprises of water impounded refractory lined Bottom Ash Hopper of adequate capacity with water seal trough and dip plates, allowing free expansion of the furnace without any air ingress.

Steam Jet Vacuum Systems Overview Steam Jet Ejectors are used in the chemical, petrochemical, pulp and paper, food, power, steel and allied industries in connection with such operations as filtration, distillation and evaporation, absorption, mixing, vacuum packaging, freeze drying, flash cooling, deaerating, dehydrating and degassing to name ...
Steam ejectors can also be combined with liquid ring vacuum pumps to create a hybrid capable of deep vacuum that ejectors can deliver but with lower energy use. Nash is globally recognized for assembling the most efficient steam jet and air ejectors and ejector vacuum systems.
2.1 Ash handling plantFIG The fly ash system handles the Major(largest) fraction of total ash.so that the majority of problems are found in the ash handling systems.ESP used for the collection of fly ash from steam generator's are mostly of dry horizontal flow.During the operation the fly ash
Wet Fly Ash Disposal System:Up to the hopper part it is same as that of Dry Fly Ash handling system. After the hopper instead of going into the vessel, the ash gets mixed with a high Pressure water and this mixture goes to a slurry tank for further pumping.
Hopper Eductors are also used extensively for ejecting sludge's from tank bottoms, for pumping sand from filter beds and for washing and conveying granular materials. Typical materials handled can be borax, charcoal, diatomaceous earth, lime, mash, fly ash, rosin, rock, activated carbon powder, granulated salt, sand, dry sawdust, light soda ash ...

Steam quality is another important performance variable. Wet steam may be damaging to an ejector system. Moisture droplets in motive steam lines are accelerated to high velocities and become very erosive. Moisture in motive steam is noticeable when inspecting ejector nozzles. Rapidly accelerated moisture droplets erode nozzle internals.
Explain the bin (central) system of pulverizing with neat sketch. 8. Explain the working of electrostatic precipitator with neat sketch. 9. Classify various ash handling system and explain pneumatic and steam jet system. 10. Draw the neat sketch of cyclone burner and cyclone separator.
Solids handling eductors can recycle solids back to the feed bin or boost vent air directly into the conveyor line. They are commonly employed in both single or double airlock installations to extend air lock life. In existing installations that employ rotary valves, solids handling eductors have been proven to improve performance and efficiency.
Figure 5: Conventional Bottom Ash Dewatering System In these systems the bottom ash was pumped from the ash hoppers to the top of tall dewatering bins using either jet pumps or centrifugal slurry pumps. In either case, the Total Dynamic Head, TDH, that these pumps were designed to overcome included the
May 07, 2014· Requirement of Ash Handling System In Thermal Power Plant's coal is generally used as fuel and hence the ash is produced as the byproduct of Combustion. Ash generated in power plant is about 30- 40% of total coal consumption and hence the system is required to handle Ash for its proper utilization or disposal.
