Hot-selling condensing hot FGR water boiler

Gas or Oil Fired FGR Split Hot Water Boiler

Introduction Features
Technology Parameters

Rated thermal power: 0.7-14MW
Rated thermal efficiency: 94-96%
Introduction：We maintain the classic three passes wet back structure. But the most important thing is we make some of outlet smoke back into the furnace to improve efficiency. This technique is called FGR technique.

Low pollution

Benefiting from the efficiency of the boiler plays to its limit, this boiler has a comprehensive function of pollution solution. That leads a substantial reduction in emissions of harmful substances such as NOx
Easy operation

We develop different controller system for each piece of our steam boiler and we make this effort to ensure the boiler is easy to operate and control. For safety, we make safe door and various devices to detect.
Classic structure

The classical three pass wet back structure is a stable structure for steam boiler for many years. Three pass smoke tunnel makes the smoke quickly and fully cooled before goes into the chimney.
High efficiency

The appliance of FGR technology makes the thermal efficiency can be as high as 95-96%. The product exhaust temperature can be reduced to 95 ℃.

Core technology

Introduction Features
Technology Parameters

FGR technology

FGR flue gas circulating combustion technology is recycling 10% to 30% of the boiler smoke back into the burner inlet to reduce the concentration of oxygen burning area at the same time.
Temperature alarm technique

When the internal temperature of the boiler or burner exceeds the safe value, the alarm device will warn and shut down the boiler in time. In this way, the boiler overtemperature operation is avoided.
PLC Full-Intelligent Control System

Fully self-developed PLC system is easy to operate. To better serve global clients, we make the system full English interface. Simple and humanized is our design philosophy when dealing with our boiler.
