About this product

Product information from the supplier.

Our advanced Gas (oil) hot water boilers are engineered for superior thermal performance, utilizing a precision-driven combustion process where natural gas or oil fuel is burned in the furnace to heat water within the pot. This continuous energy transfer ensures a steady increase in temperature, delivering high-capacity hot water tailored for demanding industrial applications.

Designed with a focus on sustainability and operational safety, these boilers integrate high-efficiency heat exchange technology and rigorous emission controls. By combining large heating surface areas with state-of-the-art automation, we provide a reliable heating solution that minimizes fuel consumption while maximizing heat output for various manufacturing environments.

Frequently Asked Questions

Q: What is the difference between a hot water boiler and a steam boiler?

A hot water boiler heats water to a specific temperature without boiling it into steam, making it ideal for space heating and process water, whereas a steam boiler produces saturated or superheated steam for power or sterilization.

Q: How does the corrugated liner improve efficiency?

The corrugated liner increases the heat transfer surface area and creates turbulence in the flue gas, which enhances heat absorption and reduces exhaust gas temperature, directly increasing overall efficiency.

Q: Can these boilers operate on both gas and oil?

Yes, we provide dual-fuel configurations that allow switching between natural gas and oil, ensuring your facility remains operational even if one fuel source is interrupted.

Q: What safety measures are included to prevent gas leaks?

Our boilers are equipped with high-sensitivity gas valve groups and an automated control system that triggers immediate shutdowns and alarms if any irregularity or leak is detected.

Q: What is the expected lifespan of these industrial boilers?

With proper water treatment and routine maintenance as specified in our manual, our boilers are designed for long-term industrial use, typically lasting 15-25 years.

Q: How are NOx emissions kept so low?

We utilize imported low-NOx burners that optimize the air-fuel mixture and control the combustion temperature, ensuring emissions stay below 30mg/Nm³.
