Dealing with mercury in an old heating system

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

mercury boilers - Boiler and Pressure Vessel engineering

Mercury boils under one atmosphere at a temperature of 677 degF (358 degC) and in a 28 inch vacuum it will condense at 455 degF (235 deg C). It is proposed to use the mercury vapor to drive a turbine and to utilize the heat from the exhaust in generating steam to drive a steam turbine.

Control of Mercury Emissions from Coal-fired Electric

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.

Industrial, Commercial, and Institutional Boilers and

Control of mercury emissions from stationary coal

Generator (also called a mercury seal generator), which was invented in 1904 to improve home hot-water heating systems. These devices may be found near the boiler in the basement or near a radiator on an upper floor. They contain several fluid ounces of mercury. Mercury spills can occur as a result of improper removal of these devices.

A tale of mercury and old heating equipment | Kefid

Sep 20, 2003 · I had heard that there was a larger mercury boiler that was operated in the 1950's in the New Jersey Meadowlands, but it was dissassembled a few years after it operated. Also, the ground water contamination had caused "surprisingly" little ecological damage.

Boiler upgrade for emissions reduction | GE Steam Power

Apr 01, 2012 · The average overall mercury removal efficiency for the low-mercury boiler setting was calculated as 28%, improving by almost 20% as it is compared to the overall Hg T removal efficiency at baseline. The results are based on three and four Hg measurements performed by OHM at the baseline and low Hg boiler settings, respectively.


Mercury Rule (CAMR)3on Hg emission control from coal-fired power generation on March 15, 2005, which requires the reduction of Hg emissions from coal-fired utility boilers of

Heating Oil Delivery | Waterbury Heating Oil | Mercury Energy

Coal burning in power plants and industrial boilers is the largest combustion source of mercury emissions in China. Together, power plants and industrial boilers emit around 250 tonnes of mercury each year, or around half of atmospheric mercury emissions from anthropogenic sources in the country.

mercury in boiler controls — Heating Help: The Wall

Mar 08, 2021 · The final emission standards for control of mercury, hydrogen chloride, particulate matter (as a surrogate for non-mercury metals), and carbon monoxide (as a surrogate for organic hazardous emissions) from coal-fired, biomass-fired, and liquid-fired major source boilers are based on the maximum achievable control technology.

Dec 10, 2002 · For a boiler feed pump controller, the MM 150SMD can be used for the pump controller. It has a snap switch in it (S). For a LWCO, the MM 63M has a No. 2 switch in it and is already a snap switch. Many locations are now forbidding use of mercury type switches for boiler applications.

The Mercury Switch Thermostat. Other uses for mercury bulb thermostats include uses for zone valves and boiler controls. These thermostats operate in much the same manner as air conditioning and heating thermostats but control different functions for heating applications. Mercury makes a great switching mechanism because it is a liquid metal.

Mercury Heater Core. Helpful Automotive Resources. How a Heater Control Valve Works (with Diagram) When the temperature outside begins to drop, it's important to have a functional heater inside of your car. On some vehicles, a component called the heater control valve plays a vital role in heater operation—and keeping your cabin warm.

Mercury capture by boiler modifications with sub

the speciation – has a strong impact on the capture of mercury by boiler air pollution control (APC) equipment.* Mercury may be present in the flue gas as elemental mercury vapor (Hg0), as a vapor of an oxidized mercury species (Hg2+), and as particulate-bound mercury (Hg p).
