Indian Float Glass Plant MEP — IS 2835 + EN 572 + ASTM C1036 + ICG + CPCB + BEE PAT

An 800 t/day Indian float glass plant demands ₹1,842 Cr MEP capex with raw-material + furnace (oxy-fuel or air-fuel) + tin float bath + lehr annealing + oxygen plant + bag-house + SCR. IS 2835 + EN 572 + ASTM C1036 + ICG + CPCB + IGMA govern. Three failures: air-fuel furnace at 12.5 GJ/t vs oxy-fuel 5.5 (55 % saving, 4-6 yr ROI) Indian industry slow to convert, furnace bottom cooling without continuous monitoring (catastrophic discharge risk), lehr annealing profile not per IS 2835 + EN 572 causing stress fracture in transit.

Indian glass float plant framework

India glass industry (Saint-Gobain Sezal + Glaverbel + AGC Asahi India + GSC Glass + Hindusthan National Glass + Borosil + Triveni Glass) operates float glass + container glass + special glass. Float plants make 4-12 mm soda-lime float glass at 700-1100 t/day. Standards stack — IS 2835 (float glass) + IS 4843 (architectural) + EN 572 (float glass) + ASTM C1036 + ICG (International Commission on Glass) + Indian Glass Manufacturers Association IGMA + worldcement + IS 13779 (battery for emergency cooling) + IBR.

800 t/day float glass plant MEP scope

Three Indian float glass plant MEP failures

1. Air-fuel furnace without oxy-fuel conversion — air-fuel at 12.5 GJ/t-glass; oxy-fuel at 5.5 GJ/t = 55 % saving but capex ₹165 Cr for oxygen plant. ROI 4-6 years. Indian glass industry slow to convert.
2. Furnace bottom cooling without continuous monitoring — refractory failure at furnace bottom = catastrophic 1550°C glass discharge. Specify continuous thermocouple + IR camera grid + emergency cooling water reserve per ICG Bulletin.
3. Lehr cooling profile not optimised — annealing must follow controlled 590°C → 60°C profile to relieve stress. Wrong profile causes glass-stress fracture in transit. Specify per IS 2835 / EN 572 + CG simulation.
