Key Features
Fully Wet-Back Furnace Design
The rear turnaround chamber is fully water-cooled, reducing refractory exposure and improving heat transfer around the furnace and convection sections.
Three-Pass Fire-Tube Structure
Flue gas passes through three heat-transfer stages before leaving the boiler, providing effective heat recovery within a compact shell-type configuration.
Stable Steam Output
The horizontal shell structure and adequate heating surface support continuous steam generation for applications with relatively steady process loads.
Automatic Operation
A compatible burner and control system can regulate combustion, monitor operating conditions and provide safety interlocks for routine unattended operation.
Typical Applications
Food Processing
Provides process steam for cooking, sterilization, drying, blanching and other thermal operations.
Textile Manufacturing
Used for dyeing, washing, drying, finishing and other processes requiring controlled steam heat.
Pharmaceutical Production
Provides steam for process heating, equipment sterilization and selected clean-steam-related systems when the required configuration is specified.
Chemical Processing
Used as a heat source for reactors, tanks, dryers and other process equipment.
Paper and Packaging
Supplies steam for drying, heating and related production processes.
Commercial and Institutional Facilities
Suitable for centralized heating, hot-water generation and other applications requiring a continuous steam supply.

FAQ
Q: How should I select the boiler capacity?
A: Selection should consider normal steam demand, peak demand, operating hours, required steam pressure, feedwater conditions and future production requirements. A capacity margin should be determined from the actual load profile rather than selected only by equipment nameplate capacity.
Q: What natural gas information is required before ordering?
A: The supplier normally needs the gas composition or specification, supply pressure, available flow rate and local gas standard. These parameters affect burner selection and combustion-system configuration.
Q: Does the boiler require a water treatment system?
A: Yes. Feedwater quality affects boiler reliability, heat-transfer performance and maintenance requirements. The required water treatment process should be determined according to feedwater characteristics, boiler pressure and applicable water-quality standards.
Q: What site conditions should be checked before installation?
A: The installation site should provide adequate space for boiler maintenance, ventilation, lifting, flue connection, gas supply and utility connections. Floor loading and access routes should also be verified before delivery.
Q: How often does the boiler require maintenance?
A: Maintenance frequency depends on operating hours, water quality, fuel conditions and local regulations. Routine inspection should cover the burner, safety devices, controls, pressure parts and heat-transfer surfaces.
Q: What spare parts should be prepared for long-term operation?
A: Common spare parts may include burner components, ignition and flame-monitoring parts, control components, gaskets, valves and other specified wearing parts. The recommended spare-parts list should be determined from the final equipment configuration.
