NTPC Unchar Boiler Accident and Reasonand My
Condolence
NTPC boiler blast: How the horrific accident unfolded at Unchahar plant Sece of event : 1. Bottom ash handling malfunctioning since last 2 days. 2. Huge build up of bottom ash inside boiler upto 16 m elevation. 3. NTPC does not stop unit hoping it can be cleared manually duringboiler running condition. 4. Open furnace manhole doors (both left and right side) at 10 m level. 5. Engage workers to poke collected clinkers (molten ash) to directsame towards bottom ash hopper so that same can be cleared throughhopper bottom. 6. Suddenly the huge mass of clinker falls down. Water of hopper getsvaporised. Huge pressure get developed. 7. Waterwall at corner 2 getscracked at fins and widened from 20 m toS panel (bottom arch portion furnace). No tube failure. 8. At the same time unburnt / semi burnt coal gets carried over to 2ndpass due to furnace pressurisation. This creates explosion inEconomiser. Economiser hopper gets blown away. 9. Due to furnace pressurisation Hot Slag (clinker) comes out throughmanhole door. NTPC personnel and workers supervising the clinkerremoval job got severely injured. 10. At the same personnel working in the vicinity of boiler gotaffected by released hot flue gase and ash.

Copper Cladded Conductor For Electrical Installation
The Copper Clad Steel Grounding Conductor is made up of steel with the coating of 99.99% pure copper. These conductors/ wires or strands are equipped with the strength of steel with the conductivity and copper with the better corrosion resistance property. The concentric copper cladding is metallurgic ally bonded to a steel core through a continuous, solid cladding process using pressure rolling for primary bonding. The copper cladding thickness remains constant surrounding steel. We use different steel grades for the steel core result in Dead Soft Annealed, High strength and Extra High Strength Characteristics. The Copper Clad Steel Wire yields a composite conductivity of 21%, 30% and 40% IACS, and available in Annealed and Hard drawn. We are delivering products with varied conductivity and tensile strength as per the customer need. Further, the wire can be processed to be silver plated or tinned copper clad steel wire.
Most Efficient JointProcess
It is efficient and superior to all existing surface –to-surface mechanical retention connectors.
What is Exothermic Welding System? Copper to Bi-Metal and Alumenium Types of Exothermic Joints:
Possible to join any bi metal except aluminum Exothermic welding is a process of making maintain free highly molecular bonding process is superior in performance connection to any known mechanical or compression-type surface-to-surface contact connector. Exothermic weld connections provide current carrying (fusing) capacity equal to that of the conductor and will not deteriorate with age. It offers Electrical connections between two or more copper to copper and copper to steel conductors. Highly portable method as it does not require any external power source or heat source, so it can be done almost anywhere. It provides strong permanent molecular bond among metallic conductors that cannot loosen and further will not deteriorate with age. Connection does not corrode with time and it offers permanent conductivity.
