  • Improve Boiler Efficiency

    In many chemical plants, the electricity the plant uses is derived from a natural gas power plant or a co-generation plant burning waste gas streams. In large boilers (Figure 1), power plants bring together air and fuel (natural gas, waste gas, oil or coal) for combustion, which creates heat. The heat boils the water, creating steam. The steam runs through a turbine, which causes the turbine to ...
