Field Project Executions & Case Studies

The facility required an upgrade from an aging, inefficient boiler to a modern high-efficiency packaged steam generation system capable of meeting variable process steam demand with tight pressure stability and low fuel consumption.

BS Energy India delivered and installed a heavy-duty 3-pass wet-back smoke-tube steam boiler package equipped with an automated modulating burner. The design features submerged rear reversal chamber geometry that eliminates maintenance-heavy refractory rear walls and delivers high thermal transfer efficiency.

Coordinated heavy crane lifting, positioning onto concrete foundation pads, foundation anchor bolting, steam header connection, water feed pump skid integration, flue stack connection, and live combustion tuning using electronic flue gas analysis.

Safe evacuation of high-temperature combustion exhaust gases from multiple utility units required engineered stacks capable of withstanding severe coastal wind loads and meeting stringent Tamil Nadu Pollution Control Board (TNPCB) emission dispersion heights.

Manufactured twin self-supporting cylindrical structural steel chimney stacks fabricated from IS 2062 Grade carbon steel plates with corrosion protection. Integrated continuous helical access ladders with safety cages, rest platforms, lightning arresters, and CPCB-compliant emission sampling ports.

Executed mobile crane rigging and hoisting operations; precision vertical alignment onto heavy foundation anchor stools; non-shrink grouting; and certified full-penetration circumferential seam welding.

The client required a complete new distribution network to route high-pressure steam from a central boiler house across a multi-building facility to diverse process reactors with zero line leakage, controlled thermal expansion, and minimal condensation loss.

Engineered isometric line routing incorporating expansion loops, steam trap drain pockets, and a skid-mounted Pressure Reducing Station (PRS). Utilized ASTM A106 Grade B seamless carbon steel piping with class-rated forged steel flanges and isolation valves.

On-site pipe spool alignment on overhead structural racks; certified high-pressure TIG/MIG welding; 100% hydrostatic pressure testing at 1.5x design pressure; and high-density rockwool thermal insulation lagging finished with protective aluminum cladding.

Installation of multi-story storage silos and heavy fuel storage tanks in an active production facility with constrained ground clearances and tight plant turnaround schedule.

Shop fabrication of precision-rolled heavy steel plate panels with weld bevelling; fabrication of rigid structural steel support columns; and coordinated dual mobile crane tandem lift engineering.

Synchronized dual-crane hoisting of vertical silo panels; continuous nighttime high-altitude structural alignment; certified welding of vertical and horizontal plate joints; and complete hydrostatic integrity leak testing.

Flue gases were exiting the existing boiler stack at over 240°C, representing substantial unrecovered thermal energy and elevated monthly fuel expenditure.

Engineered and retrofitted a compact finned-tube boiler economizer into the flue exhaust path. Incorporated spiral-welded steel fins for high heat transfer area and installed a modulating bypass damper arrangement to allow boiler operation during maintenance.

Installed structural support stands; modified flue gas duct transitions; piped economizer into boiler feedwater delivery circuit with safety relief valves and isolation bypasses; and verified live draft loss across firing rates.
