Furnaces

The lifespan of a gas furnace thermocouple is typically around 5-7 years. However, this can vary depending on usage and maintenance of the furnace. Regular inspection and replacement can help ensure the safety and efficiency of the furnace.

The Orsat apparatus is used to analyze the composition of flue gases, typically measuring oxygen, carbon dioxide, and carbon monoxide levels. The apparatus involves passing a known volume of flue gas through different chemical solutions to absorb specific gases, allowing for quantification of each component. This analysis helps assess combustion efficiency and environmental impact of fuel-burning processes.

An electric oven is used for cooking food, while a furnace is used for heating a building. Electric ovens typically have insulated walls and racks for cooking food, whereas furnaces have a heating chamber that distributes warmth through a ventilation system.

In a blast furnace, iron ore (Fe2O3), coke (carbon), and limestone (CaCO3) are commonly used. Iron ore is the source of iron, coke acts as a fuel and reduces the iron ore to iron, and limestone helps remove impurities by forming a slag.

electrolysis requires a lot of electrical energy, however this is not the same with reduction with carbon (blast furnace), which is a lot cheaper than electrolysis, but not always the most practical. :)

Chimney use to remove the flue gases and smoke from the building and from the boiler, furnace, fireplace, stove to outside atmosphere. Chimney construct as much as possible in the vertical shape to remove the smoke outside easily. Romans used hole in the bakeries to remove the smoke outside but real chimney found in Northern Europe in 12th century.

Chimney deterioration is primarily caused by exposure to the elements (rain, snow, wind), freeze-thaw cycles, and the natural aging process of building materials like bricks and mortar. Other factors such as poor construction, lack of maintenance, and environmental conditions can also contribute to chimney deterioration over time.

Salt can be separated from amphetamines through a process called acid-base extraction. Amphetamines are basic compounds, so adding a weak acid like hydrochloric acid can convert amphetamines into a water-soluble salt that can be separated from the non-soluble salt. This process allows for the isolation of pure amphetamines.

Iron ore or Haematite (Fe3O2), Carbon in the form of 'Coke', and Limestone (Calcium Carbonate 'CaCO3') are all used in the blast furnace. Iron Ore is melted down with coke, the coke burns heat into the furnace. Oxygen gas is blasted in from the sides. The carbon (C) and oxygen (O2) react to form carbon dioxide gas (CO2). At higher temperatures more carbon (C) is reacted with the carbon dioxide(CO2) to create carbon monoxide (2CO). The carbon monoxide 'steals' the oxygen from the iron oxide (Fe3O2), reducing the iron oxide to iron. Due to the impurities in the iron, it is called 'pig iron'. Limestone (CaCO3) is added to remove the impurities from the iron. The limestone (CaCO3) reacts with mainly silicate in the iron, and becomes calcium silicate (CaSiO3) and carbon dioxide (CO2). Calcium silicate is known as 'slag' and is used for construction.

Furnace oil is not one single species of petrochemical. The hydrocarbon fuel is a mixture of compounds in the range of 14 to 20 carbon atoms. The chemical formula for some of the more common molecules of heating oil might be C14H30, C15H32, C16H34, C17H36, C18H38, C19H40, or C20H42.

Hot air is blasted into the furnace to increase the temperature inside the furnace quickly by providing additional oxygen for combustion and promoting efficient fuel burning. This helps speed up the metal production process and maintain a consistent temperature for melting and refining.

A furnace is needed to keep your house warm because it generates heat by burning fuel or using electricity, which is then distributed throughout the house via ductwork or a heat pump system to maintain a comfortable temperature. Furnaces are efficient and effective at heating larger spaces compared to other heating methods.

An ashing furnace is specifically designed for high-temperature applications to burn off organic material and leave only ash residue. A muffle furnace is used for general heat treatment processes where the sample is heated in a chamber, known as a muffle, to protect it from direct contact with the heating elements.

If you are referring to the "atomic furnaces" that actually used atomic pellets to generate heat for home and personal use: They were small to moderate sized semi contained units that fuel pellets were fed into the furnace to generate heat for a domicile not to far removed in concept from the wood pellet stoves in use in the USA. today. They were primarily made and used in the former soviet states and exported in limited forms as "war surplus". Because of misuse and manufacturing flaws they were first discontinued then outright banned after multiple instances of radiation burns/poisoning (usually attributed to consumer not using as intended).

The iron produced by a blast furnace is typically referred to as pig iron. It is a crude form of iron with high carbon content, which needs to be further processed to remove impurities and adjust its carbon content before it can be used in various applications.

The power needed to run a furnace can vary depending on the size and type of the furnace. However, a typical residential furnace may require anywhere from 500 to 5000 watts to operate. It's best to consult the manufacturer's specifications or a professional to determine the exact wattage requirement for your specific furnace.

A furnace may be blowing cool air due to issues such as a dirty air filter, a malfunctioning thermostat, or a problem with the pilot light or ignition system. It is best to have a professional HVAC technician diagnose and repair the issue.

Yes this could possibly become a problem. LP gas and NATURAL gas have different properties, such as but's per cu ft, specific gravity and so on. Appliances are regulated differently for each, such as pressure and orifice sizing. A potential hazard is introduced when these properties are not compensated for. Although it is fairly easy to alter a FUEL GAS appliance from one gas to the other, some appliances may not be able to be altered. It is always a good idea to check the mfgr. listing and have an experienced/qualified person perform any modifications. (remember… gas goes… BOOM) Some mfgr's do not allow modification outside of the factory at all, or at least require a qualified/trained technician to complete the modifications to maintain the listing. SAFETY FIRST and ALWAYS… Hope this helps. Terry

Coal, distilled to drive off itscontents and leave the carbon, plus a little bit of non-volatile impurities, principally silica; in a form called Coke. (No relation to the colloquialcontraction of Coca-Cola! :-) )

If you do not have a basement, you can consider installing the gas furnace in a closet on the main floor or in an appropriate utility room. It's important to ensure the space meets the specific requirements for clearances and ventilation outlined by the manufacturer and local building codes. Professional installation by a licensed HVAC technician is recommended for safety and compliance.

Flame rectification in a gas furnace involves using an electrical signal to detect the presence of a flame. When a flame is established, the electrical properties of the flame change, allowing the sensor to confirm its presence. This signal is used by the control system to ensure the furnace continues to operate safely and efficiently.

Iron is removed from a blast furnace through a process called tapping, where a hole at the base of the furnace is opened to release the molten iron. The iron is then cast into molds to solidify and form pig iron or further processed into steel.

Your furnace may only be blowing cold air due to issues such as a malfunctioning thermostat, a clogged air filter, a problem with the pilot light or ignition control, or low fuel supply. It is best to consult a professional HVAC technician to diagnose and fix the problem.
