  • Overview of mercury control in coal-fired power plants

    During combustion, the mercury (Hg) in coal is volatilized and converted to elemental mercury (Hg0) vapor in the high temperature regions of coal-fired boilers. As the flue gas is cooled, a series of complex reactions begin to convert Hg0 to ionic mercury (Hg2+) compounds and/or Hg compounds (Hgp) that are in a solid-phase at flue gas cleaning temperatures or Hg that is adsorbed onto the surface ...

  • Upgrade of turbine intake damper controllers on SS Cape Isabel - Case Study

    Overview SS Cape Isabel is a 655ft, 15,000 ton roll on/roll off cargo ship based at Long Beach and operated by the US Military Sealift Command. Launched in 1976, the ship is powered by two steam turbines. The Reason The ship’s two turbine intake radial vane dampers were equipped with pneumatic controllers (actuators) which were now obsolete. The old ...

  • Gas boiler load optimisation controls can rectify dry cycling and reduce energy costs by 25%

    Dry cycling of gas boilers can waste a great deal of energy, even when BMS optimisation is in use. Installing gas boiler load optimisation controls can reduce this waste and help boilers run more efficientlyBuilding engineers, energy and facilities managers tend to overlook that many gas boilers waste energy through dry cycling when they are not actively contributing to the building heating and ...

  • Pollution reduction from flares by swirl vanes in a cross-flow

    The effect of swirl on the performance of a flare stack was experimentally investigated as a passive control technique for combustion in a cross-flow. The burner comprised a circular fuel nozzle with a co-annular airflow, swirled by a concentric vane swirler, with a crosswind of air at the flare tip. It was found that the flames issuing from swirl-vane flare tip were shorter and had wider flame ...

  • Polish gas from Polish coal: environmental benefits

    The development of coalbed methane gas from Polish coal offers a significant opportunity to reduce noxious pollutant emissions associated with coal combustion. A review of energy supply and consumption within Poland, and of available coalbed methane resources, indicates that use of coalbed methane could eliminate 40-60 million tonnes of sulfur dioxide and particulates from the atmosphere, save ...

  • The resurgence of waste-to-energy and conversion technologies: Where’s the risk?

    Waste processing technologies have come a long way in the last century. The technology to extract energy from the combustion of solid waste has been in use since 1898, when the first waste-toenergy (WTE) facility was built in New York. Since that time, WTE technologies have evolved from incinerators that were simply destruction units to large-scale mass-burn combustion and refuse-derived fuel ...

  • Frequency Converter energy savings on Boilers

    Boilers and heaters account for a significant share of a plant's purchased fuel cost. Combustion air fans are necessary to provide enough combustion air to the boiler or heater's burner system. Louvers, inlet guide vanes or frequency converters control the amount of air allowed into a boiler. Configuring a combustion air fan to allow the proper amount of air into the burner can improve boiler ...
