Fuel Conversions: Natural Gas

Flame Burner

The cost of natural gas makes fuel switching an attractive option for owners and operators

B&W’s natural gas conversion experience is proven: many power boiler owners and operators have successfully converted their existing units to 100 percent natural gas firing systems, significantly reducing annual fuel and plant operating costs.

Boiler Capacity Increases

Technology advances to increase unit capability, operability and availability

B&W considers all the key issues when optimizing a unit, including understanding how boilers age, identifying the critical components, and determining the general types of changes and enhancements possible. These elements are then combined with operating experience and equipment condition assessment to develop an integrated strategic plan for each boiler and each component in the boiler.
