  • Series 123/125 | Boiler Water Level Control is designed

    Series 123/125 Boiler Water Level Control Heavy Duty, Cast Iron Chamber. The Series 123 & 125 Boiler Water Level Controls are designed for boiler applications, the 123 is primarily used for low water cut-off or feed-water control. Other applications include condensate tanks and deaerators. A special snap action switch mechanism eliminates frequent operation due to surging water level.

  • Mercury emission and adsorption characteristics of fly ash

    Jul 10, 2020 · The mercury emission was obtained by measuring the mercury contents in flue gas and solid samples in pulverized coal (PC) and circulating fluidized bed (CFB) utility boilers. The relationship was obtained between the mercury emission and adsorption characteristics of fly ash. The parameters included unburned carbon content, particle size, and pore structure of fly ash. The results showed that

    The mercury was condensed in two condenser/boilers that generated 129,000 pounds of steam per hour, at 280 psi and 700F (persumably the steam was reheated in the boiler). The plant ran from 1928 to 1947. In 1947, the mercury unit was rebuilt, and the generator rewound for 15,000 kW.

  • Mercury Emission and Removal of a 135MW CFB Utility Boiler

    Abstract. To evaluate characteristic of the mercury emission and removal from a circulating fluidized bed (CFB) boiler, a representative 135 MW CFB utility boiler was selected to take the onsite measurement of mercury concentrations in feeding coal, bottom ash, fly ash and flue gas using the US EPA recommended Ontario Hydro Method (OHM).
