A Menzies Cone is used to separate crushed anthracite coal from rock. Inside the cone is slurry mixture of water and magnetite. The magnetite slurry has a high specific gravity. This allows the lighter coal to float, the rock and coal with a lot of rock in it sinks. A barometric damper is a device that is installed on flue pipe between the exhaust port on your heating appliance and the thimble on the chimney. The function of this device is to help regulate the draft. These are typically installed on any heating appliance with a flue and a chimney with the exception of wood. A barometric damper can be used on any type of coal heating appliance but some prefer a manual damper The barometric damper has a swing gate on it, this gate will open when there is excessive draft. It's calibrated by a weight on the face of the gate and it needs to be installed level. When the gate is open this allows room air can be pulled into the flue and chimney. This increases operating efficiency because it prevents air from being pulled through your heating appliance sending a lot of heat out the chimney. The loss of heated room air is far less than heated air from the heating appliance. EFM trivets were first issued in 1953 and that practice continues to the present. They are given to employees, EFM dealers and friends. The texts are a mixture of broken English and Pennsylvanian Dutch that commemorates the heritage EFM's founder. Anthracite coal is the highest grade of coal. Anthracite is dark black, very shiny and has a glas* like consistency. In the United States the primary source is Northeastern Pennsylvania. It has an average BTU content of 24 to 25 million per ton but can exceed 28 Anthracite has very high carbon content that will range from about 85 or 95 percent. It burns with a bright blue flame similar to what you would expect from natural gas. It also has a low ash and low sulfur content. These characteristics and others make it ideal for a home heating fuel even if the heating unit is placed directly in the living space.
