Gas Water Tube Steam Boiler

The Gas Water Tube Steam Boiler is a modern industrial device designed for efficient steam production. Using natural gas as fuel and a water-tube heat exchange structure, it achieves rapid, stable, and energy-efficient steam output. Widely used in industrial production, commercial services, and energy-intensive sectors, it meets diverse needs from low loads to high capacities, making it an ideal choice for green manufacturing and sustainable operations.

1. Main Structure

Adopts a double-drum longitudinal D-type arrangement, with clear partitioning of the furnace and convection tube bundles and a rational arrangement of heating surfaces. The furnace is surrounded by a full-film water-cooled wall, providing excellent sealing performance and significantly reducing heat loss and flue gas leakage. The upper and lower drums, convection tube bundles, water-cooled walls, and headers form a closed-loop water circulation circuit, ensuring sufficient water circulation power and smooth flow, eliminating local dry burning and water circulation failures.

2. Combustion System

Equipped with a fully automatic proportional control burner, achieving full automation of ignition, combustion, load regulation, and flameout protection. The furnace uses micro-positive pressure combustion, resulting in good flame coverage, complete and stable combustion, and low nitrogen oxide emissions, meeting environmental emission standards.

3. Convection and Tail-End Heat Exchange

The convection tube bundles are arranged in a staggered/in-line combination to enhance flue gas turbulence and heat exchange efficiency. An economizer/condenser can be optionally installed at the tail end to recover waste heat from the flue gas, reduce exhaust temperature, and further improve the overall thermal efficiency of the unit.

4. Boiler Drum and Steam-Water Separation

The upper boiler drum is equipped with a high-efficiency steam-water separator, achieving excellent separation results and high steam dryness to meet the requirements of precision processes. The boiler drum has ample internal space, resulting in minimal fluctuations in water level and steam pressure, and stable operating parameters.

1. High Efficiency and Energy Saving: Thermal efficiency can reach over 95%. The water-pipe heating surface absorbs heat quickly and exchanges heat fully. Combined with waste heat recovery at the tail end, fuel utilization is high, significantly reducing energy costs in long-term operation.
2. Safe and Reliable: Equipped with multiple interlock protections for high and low water levels, extremely low water levels, overpressure, flameout, gas leakage, and overheating; complete with safety accessories such as safety valves, pressure gauges, and water level gauges; the structural design fully considers thermal expansion compensation, ensuring reliable long-term operation.
3. Stable Output: Stable evaporation and pressure output, rapid response to load changes, and continuous and stable operation, meeting the continuous steam supply requirements of continuous production scenarios.
4. Environmentally Friendly and Low Noise: Complete combustion, with emissions of smoke, nitrogen oxides, and sulfides meeting standards; overall sealing and noise reduction design, resulting in low operating noise, suitable for areas with stringent environmental requirements.
5. Environmentally Friendly and Low Noise: Intelligent and Convenient.
   Equipped with a PLC intelligent control system and a touch screen for visual operation, it monitors parameters such as pressure, water level, temperature, and combustion status in real time. It supports automatic start/stop, automatic adjustment, fault alarm and recording, reducing the intensity of manual operation.
