INDURE Products for thermal power plant


  • Clinker Grinder

    Bottom ash from the conveyor is grounded in the clinker grinder & pumped out for disposal.


  • Equalizer Value

    Used with an Air Lock Tank, it alternately pressurizes and vents the air lock chamber as the air lock valve switches from one pressure zone to another.


  • Buffer Hopper

    Used to discharge the fly ash extracted from various fly ash collection chutes to pressure transporter system in case of vacuum/pressure extraction system and pressure transportation system.


  • Bottom Ash Hopper Gate

    Clinkers from the bottom ash hopper pass through the gate onto ash conveying line. The gate is partially submerged in water.


  • Material Handling valve

    Installed under Electrostatic Precipitator for conveying fly ash. It works under vacuum & pressure simultaneously.


  • Knife Gate Valve

    Linear shut off valves, used in slurry as well as dry application. Range : 100 NB – 400 NB


  • Square Knife gate valve

    Used for dry solids in gravity feed applications to open or shut off the flow. Custom built for sizes.


  • Hydrobin Gate

    Receives bottom ash and coarse ash in slurry form. The ash gets settled and water overflows from hydrobin to the settling tank.


  • Bottom Ash Hopper

    Hopper collects red hot clinkers discharged from the boiler.


  • ASH Slurry Pump

    Heavy duty, high efficiency pumps to pump out the fly ash or bottom ash.


  • Hydro Ejector

    A high speed water jet pump used for conveying ash through the pipe line for disposal.


  • Hydromix Dust Conditioner

  • Collector Tank

    It collects fly ash slurry from wetting head for the uniform discharge to slurry sump.


  • Rotary Feeder

    It controls the discharge of free flowing material from hopper thereby sealing against a pressure difference and regulates quantity.


  • Air Lock Tank

    It gravity feeds dry, freely flowing material from one pressure zone to another, while isolating the pressure zones from each other.


  • Air Oil Converter Tank

    Compressed air from the mains is converted into hydraulic high pressure by these pressure converters.


  • Rotary Segregating Valve

    It is a chamber with two gates, while controlling the chamber pressure, aeration at each gate helps to keep the material free flowing.


  • Air Washer Assembly

    The conveying air passes through it thus vetting the fine dust and allowing the clean air to escape through outlet.


  • ASH Intake Valve

    It acts as a transition from the hopper to the conveying line, a swing type valve to provide on-off ash flow control in vacuum conveying applications.


  • Double Dsic Value

    It provides tight shut-off under the most severe service conditions under vacuum and pressure of ash flow.


  • Feed Gate Housing

    It is installed below the Bottom Ash Hopper, it controls the discharge of bottom ash and feeds bottom ash to Clinker Grinder.

    Used for directing material flow from a single source to multiple destinations. Designed to handle the gravity feed of dry & any other free flowing material.


  • Feeder Ejector

    It makes slurry of fly ash from Economizer, APH & ESP hoppers. The high pressure water jet slurrifies the fly ash and discharges it into the sluice way.


  • Shuttle Conveyor

    Moves back and forth on the track system with multiple or continuous pile discharge.


  • Rack & Pinion With Rod Gate

    Rod gate Is designed to withstand impact load resulting from large sized lumps falling from the storage silo, above. Rack & Pinion gates are used in an application in which the flow of materials needs to be shut off, and then restored later.
