Specify a sealed combustion furnace or boiler, which will bring outside air directly into the burner and exhaust flue gases directly to the outside, without the need for a draft hood or damper. Furnaces and boilers that are not sealed-combustion units draw heated air into the unit for combustion and then send that air up the chimney, wasting the energy that was used to heat the air. Sealed-combustion units avoid that problem and also pose no risk of introducing dangerous combustion gases into your house. In furnaces that are not sealed-combustion units, back drafting of combustion gases can be a big problem. Energy efficiency upgrades and a new high-efficiency heating system can often cut your fuel bills and your furnace's pollution output in half. This water flows to low-profile baseboard heating units that radiate the heat from the water out into the room via thin metal fins surrounding the water pipe, typically made of carbon steel.
Even so, in Britain today, where coal launched the Industrial Revolution more than 200 years ago, there is still a constituency for solid fuel heating. The Appalachian Region contains some of the most important deposits of bituminous and anthracite coal in the the eastern United States. Nine states contain what historically amounted to 75 percent of total annual coal production as recently as 1970. Increased production in the western U.S. has brought eastern production numbers to a lower fraction, but three of the largest coal-producing states are located in the east (Miller, 1-51). Anthracite coal, or hard coal, is abundant in the Northeastern United States. It naturally contains little sulfur, produces virtually no smoke or particulate emissions, and is clean to touch.
Coal in the Home
Reluctance of many homeowners and architects to adopt passive technologies are discussed, along with the probable effects of developments in the field of materials. Also included are programs suitable for use with the T159 calculator that extend the design methods introduced.

Electric Resistance Heating Electric resistance heating can be expensive to operate, but may be appropriate if you heat a room infrequently or if it would be expensive to exte...
To get an idea of how much high-quality coal can produce, one ton of anthracite coal equals about 8,200-kilowatt hours of electricity. Those gases are then burned at high temperatures to produce heat that is transferred into the water jacket. The heated water is used through a series of exchange units to heat your home, hot water, swimming pool, or outdoor buildings. A coal-fired furnace such as our Heatmasterss C Series offers flexibility and can be easily connected to almost any existing heating system. When you replace an older furnace or boiler with a new 90+ AFUE appliance or a heat pump. In this case, the heating appliance will no longer vent into the old chimney, and if the combustion water heater is present it will now vent through an oversized chimney.

If you live in a cold climate, it usually makes sense to invest in the highest-efficiency system. In milder climates with lower annual heating costs, the extra investment required to go from 80% to 90% to 95% efficiency may be hard to justify. However, keep in mind that higher efficiency units will have lower emissions than units in the 80% range. Energy-efficiency improvements will save money on a new furnace or boiler, because you can purchase a smaller unit. A properly sized furnace or boiler will operate most efficiently, and you'll want to choose a dependable unit and compare the warranties of each furnace or boiler you’re considering.
This term is used to describe the overall climate control system within a home, referring to both the heating and cooling equipment. Coal ash is a byproduct of burning coal, which can come out powdery, coarse, molten, or wet. The amount of ash contained in coal can vary from just under 10% to as much as 20% or more.
Retrofitting Your Furnace or Boiler
Some fan-assisted, non-condensing furnaces and boilers, installed between 1987 and 1993, may be vented horizontally through high-temperature plastic vent pipe . This type of venting has been recalled and should be replaced by stainless steel vent pipe. If horizontal venting was used, an additional draft-inducing fan may be needed near the vent outlet to create adequate draft. Floor furnaces may have special venting problems because their vent connector exits the furnace close to the floor and may travel 10 to 30 feet before reaching a chimney.
Check to see if this type of venting or the floor furnace itself needs replacement. If you smell gases, you have a venting problem that could affect your health. Contact your local utility or heating contractor to have this venting problem repaired immediately. In reality, there are two types of systems used with these older radiators. True steam boilers actually do circulate gaseous steam through pipes to individual radiators, which then condenses back to water and flows back to the boiler for reheating. Modern radiator systems circulate hot water to radiators via electric pumps.
In the interest of environmental stewardship, restoring mined land has become a standard practice for types of surface mines through acts like the Surface Mining Control and Reclamation Act . By re-layering rock, dirt, and soil onto mined land, areas can become economically viable again for plants and animals to thrive. Most coal production in the U.S. is done by way of surface mining, rather than underground. Surface mining, as the name suggests, is done by removing the soil and rock covering the mineral deposits. This is done as opposed to underground mining, in which minerals are removed through shafts or tunnels.
Coal exists in almost all countries worldwide and is the most used solid fuel in the world. Known by the Greeks and Romans, coal received its first usage boost in Medieval Europe, several hundred years after the Roman Empire fell. During the Industrial Revolution, a coal boom arose from the use of coal to produce coke for iron smelting and fuel for locomotives and steam engines. Electric lighting of the late 1800s led to large scale coal combustion for electric utilities and independent power producers. After World War II, coal was still relied on for nearly 75 percent of total energy use in the United States (Miller, 1-51). Alternate Heating Systems manufactures alternative fuel burning heating equipment and sells throughout the US, Canada, and internationally.
Coal has been a steadfast source of energy in the United States for over 200 years. If your furnace or boiler is old, worn out, inefficient, or significantly oversized, the simplest solution is to replace it with a modern high-efficiency model. Old coal burners that were switched over to oil or gas are prime candidates for replacement, as well as natural gas furnaces with pilot lights rather than electronic ignitions. Newer systems may be more efficient but are still likely to be oversized, and can often be modified to reduce their operating capacity. Traditional boiler and radiator systems include a central boiler that circulates steam or hot water through pipes to radiator units positioned strategically around the house. Older homes and apartment buildings in North America often are heated with these systems.
Active solar heating may be the most efficient option for heating your home. Eliminate trapped air from hot-water radiators once or twice a season; if unsure about how to perform this task, contact a professional.

A central furnace or boiler's efficiency is measured by annual fuel utilization efficiency . The Federal Trade Commission requires new furnaces or boilers to display their AFUE so consumers can compare heating efficiencies of various models. AFUE is a measure of how efficient the appliance is in converting the energy from fuel to heat over the course of a typical year. In addition to conventional baseboard heaters, there are electric radiant heaters that heat with radiation.
Some HVAC systems share components with the home's cooling equipment, some work independently, and some provide both heating and cooling. Burning quality anthracite produces nearly 25 million gross BTUs per ton. It can conveniently be used in areas where wood stoves are banned or restricted due to factors such as air pollution or forest fire risk from chimney embers. Anthracite has both a higher relative energy density than bituminous, as well as a lower percentage of volatile matter.
China's coal fires destroy over five times more coal than the nation mines, and coal fires in China alone add up to about 3 percent of the whole Earth's fossil-fuel CO2 load. When I was a kid in the mid-1960s, we moved to a house that had a pile of coal in the cellar—lump coal, nice big chunks with a clean cleavage and little dust. The current heating system was a fuel-oil furnace, and all trace of the coal furnace was long gone. So for a while, my family revisited the 1800s, the days of King Coal, and burned coal at home.
