L&T MHI Boilers, India
Thermal power plant
Jaypee Nigrie Super Thermal Power Project comprising of 2x660 MW super-critical units will be set up by JPVL at a site in Nigrie Village, Tehsil, Deosar, District Singrauli in Madhya Pradesh, India. The Nigrie Thermal Project is expected to utilize coal from two captive coal blocks, the Amelia (North) and Dongri Tal II coal block, with total coal reserves of 250 megatons of coal. These coal blocks contain sufficient coal reserves to fuel the project over long term. This boiler structure houses steam/water-cooled furnaces with separators, water wall headers, super heater and re-heater system, spring loaded safety valves, attemperator system for super heater and re-heater systems, economizer system, trisector type regenerative air heaters, ateam coil air preheaters (SCAPH), integral piping, air and gas ducts, buck stays and tie bars, soot blowers, raw coal bunkers and supports and chutes, pulverizers, fuel piping, flash tanks, garbage chutes, cable trays, roofings, side claddings, galleries, walkways, platforms, and all other auxiliaries and equipment among other.
Huge productivity gains from adopting 3D
Typically, the boiler structure is made of structural steel with overall requirement of approximately 15,000 megatons and approximately 20,000 part drawings and 13,000 assembly drawings are generated during detailed engineering stage. The model involves all the complexities with respect to layout, interfaces with all equipment/system and their operation and maintenance requirement. There are huge productivity gains and engineering time cycle reduction by integrating various stages of engineering and improved information management by adoption of 3D modeling techniques with Tekla Structures and other 3D packages. This also eliminates duplication of efforts at various stages of analysis, design and detailing and saves vast amounts of time currently spent in trying to find the latest up-to-date information, interpreting it, and re-entering it into other systems. Thereby, the project will achieve complete freedom from risks of errors, misinterpretation and rework due to the errors slipping to the construction site.
