6 Ton Gas Steam Boiler Solutions And Prices

A common solution for a 6-ton gas steam boiler is one 6-t/hr gas steam boiler or two 3-t/hr boilers. A single 6 t/h unit benefits from economies of scale in pressure‑part fabrication and heat‑transfer surface, while two 3 t/h units offer operational flexibility and redundancy at potentially lower entry cost. Below we break down basic, mid‑range, and high‑end price estimates for each configuration based on recent market listings.

1. Single 6 t/h Gas Steam Boiler

1.1 Basic Configuration

A no‑frills 6 t/h fire‑tube boiler with standard steel, mechanical controls, and minimal auxiliaries is available starting around USD 5 000–10 000 per set.

1.2 Mid‑Range Package

Upgrading to a reputable burner brand, PLC‑based control panel, economizer, and improved feed‑water treatment typically pushes prices to USD 40 000–60 000.

1.3 High‑End Turnkey System

A fully packaged 6 t/h system—including ultra‑low‑NOₓ burner, full automation, advanced water‑treatment skid, skid‑mounted feed pumps, and stack—can exceed USD 80 000–100 000+.

2. Two 3 t/h Gas Steam Boilers

2.1 Basic Configuration

Entry‑level 3 t/h boilers on bulk marketplaces range USD 3 000–5 000 each, so two units cost USD 6 000–10 000 total.

2.2 Mid‑Range Package

With mid‑tier burners, PLC controls, and economizers, a single 3 t/h unit runs USD 10 000, making two about USD 20 000 combined.

2.3 High‑End Turnkey System

High‑spec 3 t/h boilers (premium metallurgy, advanced automation, emissions controls) list around USD 45 000 each, for USD 90 000 total.

3. Comparative Insights

• Upfront Cost

  • Basic: Two 3 t/h units (~USD 6 000–10 000) can undercut a basic 6 t/h package (USD 5 000–10 000), though per‑ton cost is slightly higher.

  • Mid‑range & High‑end: Single 6 t/h systems achieve better per‑ton pricing due to shared pressure parts, falling around USD 6 667–10 000 per ton at the high end versus USD 6 667–15 000 per ton for two 3 t/h units.

• Operational Flexibility & Redundancy

  • Two‑boiler scheme allows one boiler to run while the other undergoes maintenance, reducing downtime risk.

  • Single unit may optimize fuel efficiency and requires simpler piping, but lacks backup if it trips offline.

• Footprint & Installation

  • A single 6 t/h boiler usually occupies less floor space and involves fewer auxiliary skids.

  • Two smaller boilers can fit into tighter modular footprints and will spread structural loads more evenly.

• Recommendation

  • Tight budget/basic needs: Two 3 t/h boilers.

  • Continuous high‑load steam demand: Single 6 t/h boiler for better per‑ton cost.

  • Critical processes requiring redundancy: Two 3 t/h boilers with staggered operation schedules.

Always verify with suppliers—including freight terms (FOB vs. DDP), currency fluctuations, and raw‑material surcharges—before finalizing equipment purchase.
