Stirling Boiler
B&W’s Stirling® boiler has provided dependable steam to industry for more than 100 years. Since 1960 B&W has sold more than 240 Stirling power boilers that are providing more than 75 million lb/h steam flow, burning a wide variety of fuels. Many more vintage Stirling boilers installed prior to 1960 are still in operation today. A proven and flexible design has made the Stirling power boiler adaptable for applications in a variety of industries.
| Feature | Benefit |
| Custom designed within a framework of pre-engineered components | Minimizes engineering costs and delivery times, while meeting specific steam and fuel conditions |
| One- or two drum designs | Provides versatility of steam capacities,pressures and temperatures |
| A variety of furnace configurations and combustion technologies | Accommodates a wide range of specified fuels |
| Proven steam drum design | Improved steam circulation provides quality steam for turbine or process applications; minimizes water level swings to accommodate rapid and wide load changes |
| Completely water-cooled furnace with gas-tight membrane construction | Ease of maintenance (no furnace refractory), maximum safety and faster installation |
| Spray attemperator for steam temperature control | Allows steam temperature and pressure to be maintained throughout a wider control range |
| Proven auxiliary equipment | Less downtime and maintenance costs and more efficient long-term operation |
