Horizontal energy-saving condensing steam boiler using FGR

Gas or Oil Fired FGR Integrated Steam Boiler

Introduction Features
Technology Parameters

Rated Evaporation: 1-20 t/h
Rated thermal efficiency: 100-104%
Introduction：The most important thing is we make some of outlet smoke back into the furnace to improve efficiency. This technique is called FGR technique. You will spend less area and less fuel consumption when you adopt this boiler in your factory or your heating system.

FGR technology

The integrated structure is a newly designed structure which is applied on steam boiler. Compared with the traditional split three pass wet back structure, this boiler takes less area and works with better performance.
Advanced structure

The integrated structure is a newly designed structure which applies on steam boiler. Compared with the traditional split three pass wet back structure, this boiler takes less area and makes better performance.
Low pollution

Benefiting from the efficiency of the boiler playing 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.

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.
Big size corrugated furnace

Our engineers make an important decision. That is to make bigger furnace. This brings more enough burning and the better way to save fuel. Besides, according to data, we found this can reduce harm to the boiler body.
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 operation is our design philosophy when dealing with our boiler.
