Water Tube Hot Water Boiler

Water Tube Hot Water Boiler

Thermal power: 14000~105000KW

Thermal efficiency: >16~25 bar

Introduction:One of the latest advances in hot water production technology is the use of water tube boilers. This type of boiler is distinct from conventional fire tube boilers. Water tube boilers are more efficient than fire tube boilers, generating more hot water but using less fuel. They are also much safer than fire tube boilers and easier to manage when it comes to routine inspections and maintenance.

Features

01

Environmental Protection

The boiler adopts the design method of recovering residual heat. There is a vertical condenser at the end of the boiler. The condenser can greatly reduce the temperature of flue gas and reduce harmful substances.

02

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 dirty water.

03

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.
