Water Tube Gas Steam Boiler

The Water Tube Gas Steam Boiler is a D-type packaged boiler with a membrane water-wall structure, designed for stable steam generation in industrial processes.

(For reference only, specific requirements and arrangements will be made accordingly)

The D-type layout separates the furnace and convection heating surfaces to provide a compact heat-transfer structure and facilitate inspection and maintenance.
Welded membrane walls form the furnace enclosure, reducing heat loss through the furnace wall.
The boiler can be configured for natural gas and other compatible gaseous fuels according to local fuel specifications, burner requirements and emission regulations.
The boiler is manufactured as an integrated industrial boiler system to reduce on-site installation work compared with a fully field-fabricated boiler arrangement.

Feedwater enters the boiler circulation system and is heated through water-cooled furnace walls and other heating surfaces. Gas combustion generates high-temperature flue gas, which transfers heat to the water/steam circuits through the furnace and convection heating surfaces.
As water absorbs heat, steam is generated and separated before being supplied to the process system. Depending on the required steam condition, the boiler can be configured with appropriate steam heating or superheating equipment.
The D-type arrangement integrates the furnace, convection heating surfaces and steam-water system into a compact boiler structure.

For overseas distributors, EPC contractors and industrial end users, the boiler can be engineered according to project-specific operating conditions.

Available Customization

Established Boiler Manufacturing Experience
Founded in 2002, Chengde has more than two decades of experience in pressure equipment and energy equipment manufacturing.
Integrated Manufacturing Capability
Three manufacturing bases and approximately 69,000 m² of standardized workshops support fabrication of pressure equipment and related industrial systems.
Pressure Equipment Qualifications
The company holds A2 pressure vessel manufacturing and related design and installation licenses, supporting projects involving pressure-bearing equipment.
International Market Compliance
ASME and CE certifications are available for projects requiring recognized international compliance frameworks. Final certification scope should be confirmed for each boiler model and project.
Project-Based Engineering
Boiler configuration can be developed according to steam demand, fuel conditions, pressure requirements, installation constraints and local standards rather than relying on a fixed standard configuration.

Each boiler is prepared according to its transportation dimensions, weight and project delivery requirements.
Packaging: Standard export package or customized packaging.
Shipping: Sea freight is suitable for complete boiler systems and heavy equipment. Air express can be arranged for documents, samples or selected small components where applicable.
For oversized boiler components, transportation weight and dimensions should be confirmed before shipment so that lifting, containerization and site access can be planned in advance.
