Customization & Support

• Customizable: Tailored design options to meet your specific industrial needs

• Proven Reliability: Long-term collaboration with clients—e.g., Huayi Chemical, who purchased a 50 t/h NSZS boiler in 2021. After four boiler purchases totalling 300 t/h, they’ve reported zero operational failures, stable performance, and significant fuel savings—amounting to millions in savings.

Why Choose a Water‑Tube Structure for Large Boilers?

• High-pressure capability: Water‑tube steam boilers can safely operate at 3–8 MPa due to smaller-diameter tubes.

• Rapid response: Faster heat-up and load adjustment due to better circulation dynamics.

• Enhanced safety & purity: Superior dryness (>99%) and stable steam quality ideal for sensitive processes.

Steam Boiler For Sale FAQs

1. What is the natural gas consumption for a 70 t/h steam boiler?

• Typical natural gas consumption ranges from 10,500–11,000 Nm³/h, depending on system efficiency and steam conditions. Based on available spec sheets, similar 70 t/h NSZS models consume about 10,761 Nm³/h at 1.25 MPa and >99% efficiency.

2. Is fuel oil or natural gas cheaper to operate?

• It depends on local fuel prices, but historically, natural gas is often more cost-effective and environmentally friendly. However, discount heavy oil may be competitive in some regions. A precise fuel cost analysis (fuel cost per GJ) is recommended for accurate comparison.

3. How much does a 70 t/h gas-fired steam boiler cost?

• Rough market estimates (e.g., NSZS series) range from US $700,000 to $1200,000, depending on configuration, fuel type, and additional accessories.
