Efficiency of large gas or oil FGR water boilers

Features

Introduction Features
Technology Parameters

Environmental protection

The boiler adopts the design method of recycling residual heat. There is a vertical condenser at the end of the boiler. The condenser can greatly lower the temperature of flue gas and reduce harmful substances.
High efficiency and energy saving

Large furnace area ensures adequate fuel combustion. The insulation material is made of high quality material, which ensures the minimum heat loss and energy saving of fuel.
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 exhaust gas.
Easy operation

We develop different controller system for each piece of our steam boiler and we make this effort to ensure the boiler to be operated and controlled easily. For safety, we make safe door and various devices to detect.
