方快低氮FGR燃气蒸汽锅炉

Fangkuai FGR Technology，It is a technology that uses the flue gas at the outlet of the boiler to enter the boiler again as inlet air through equipment, reducing the flame temperature and thus suppressing the production of NOx. In order to perfectly apply this technology to gas boilers, the technical R&D personnel of Fangkuai Boiler conducted multiple experiments and records on the boiler structure and design, and finally optimized it continuously to control NOX emissions within the standard range.

方快低氮FGR燃气锅炉结构

Original FGR technology tested NOX<27mg/m³

Independent innovation of FGR technology for low nitrogen, energy saving and environmental protection
Adopting new combustion technology to configure the condenser
Improve thermal energy utilization efficiency by over 8%
Save nearly 10% of natural gas fuel

方快FGR燃气锅炉结构特点

Special structural design significantly improves product performance

Adopting a conical furnace structure (partially) to avoid the accumulation of high-temperature flue gas and ensure low nitrogen emissions;
The diameter of the large furnace chamber ensures sufficient space for flue gas recirculation and recirculation;
Large water volume design, the boiler is not sensitive to load fluctuations;

方快承压热水锅炉控制面板

The operation interface is intuitive and simple, and the running status is clear at a glance

Adopting high-resolution color touch screen
Real time dynamic display of the operating status and flame changes of burners, circulation pumps, etc., at a glance.
A multi-level pop-up menu in Chinese simplifies, organizes, and intelligentizes boiler monitoring
Chinese troubleshooting guide, easy to operate

方快燃气热水锅炉防护装置

Multiple intelligent warning functions ensure safe and efficient operation

Multiple safety protections such as electric contact pressure gauges and safety valves;
Equipped with high pressure protection: When the pressure inside the boiler exceeds the maximum pressure set by the user, the overpressure indicator light will turn on, the inspection light will flash, an alarm will sound, and the burner will be prohibited from working (to prevent further pressure increase).
Equipped with scale alarm function: Real time monitoring of the formation of scale on the heating surface, and automatic alarm prompt once exceeding the standard.
It has the ability to promptly prohibit the operation of the burner and sound an alarm in case of power outage, undervoltage, overcurrent, short circuit, phase loss, over burning prevention, and other sudden faults.
Equipped with over temperature protection function: When the boiler outlet water temperature is higher than the set value, the controller (electric contact bimetallic thermometer sends a command) prohibits the burner from working and emits an alarm sound.
