Our Gas and Oil Fired Molten Salt Boiler represents the pinnacle of thermal engineering, specifically designed for high-temperature industrial applications. Utilizing a wet-back internal combustion two-pass structure, this boiler achieves exceptional efficiency and a compact footprint. By integrating micro-positive pressure operation, we have significantly enhanced combustion intensity and eliminated air leakage at the furnace door and flue, ensuring maximum thermal output and operational stability.

Engineered with advanced EDA technology and high-efficiency condensation systems, the boiler optimizes flue gas flow and heat exchange to reduce exhaust temperatures and minimize energy waste. The system is coupled with a world-class PLC automation core from Siemens, providing real-time monitoring of pressure and temperature through a closed-loop PID control system. This ensures a precise, safe, and sustainable heating solution that meets stringent national low-nitrogen emission standards.

Frequently Asked Questions

Q: What are the primary advantages of using a molten salt boiler over a traditional steam boiler?

Molten salt boilers can operate at significantly higher temperatures (up to 450℃) without the high-pressure risks associated with steam, providing superior heat transfer for specific industrial processes.

Q: How does the low-nitrogen emission technology work in this equipment?

By utilizing a new combustion design and high-precision imported burners, the boiler optimizes the fuel-air ratio to minimize the formation of nitrogen oxides during the combustion process.

Q: Is the PLC control system customizable for my specific plant needs?

Yes, our control modules have powerful expansion capabilities, allowing for tailored group control, remote monitoring, and specific PID parameter tuning based on customer requirements.

Q: What is the impact of the condensation technology on operational costs?

Condensation technology effectively reduces exhaust gas temperatures and recovers latent heat, which significantly increases thermal efficiency and reduces fuel consumption costs.

Q: How is the boiler surface temperature kept below 50 degrees Celsius?

We utilize a combination of reasonable structural design and premium-grade refractory and heat-insulating materials to minimize radiation heat loss.

Q: Which burners are used in the gas/oil fired molten salt boiler?

We use imported burners from several well-known international brands, ensuring that the equipment adapts to various fuel qualities and application scenarios while maintaining high safety standards.
