New Concept of Waste Heat Steam Generation

Raipur Power Gen has developed a New concept of WHRB( Waste Heat Recovery Boiler) from sponge Iron Kiln.

In General Sponge Iron Kiln we have for example 100tpd( tones per day ) that generates 24,000 cum/hr hot gases at 950degC to be used for WHRB to produce steam of 10 tph (tones per hour ) , 64ata, 485degC with each boiler attached with 100 tpd Sponge Iron Kiln .
We know in this we would need 3 WHRB’s would be needed under 3 separate kiln.
In the new concept that RPG has developed we have combined 3X100 tpd sponge from Hot Gas duct in one WHRB (waste heat recovery boiler) having isolation slide gate (water cooled ) at inlet of hot duct on riser side.
This slide valve can withstand temperature upto 1600degC and by valve controlling we can control the pressure inside the kiln if necessary.

After combining all the three duct’s in one WHRB we can get waste gas of 3X24000cum/hr & corresponding steam generation 30 tph (tonne per hour) for running steam turbine generator. And now if one kiln is under shutdown we are providing pulverized coal nozzle to generate more gas vice versa we would get more steam from waste heat boiler. The coal nozzles and slide gates valves are imported.

The Operation of this kind of a project under my guidance will begin from JUNE 09.
For which boilers are under erecting stage.

The total design and concept has been verified by boiler design experts.
We sincerely and firmly believe and wish that we will achieve success in our developmental project and in future times this can be used with coal dust in plant for recycle.
