Furnaces

Two common contaminants found in water used to cool blast furnaces are iron and sulfur. Iron can accumulate in the water from the contact with the metal parts of the furnace, while sulfur can be present due to the combustion of sulfur-containing fuels used in the furnace operation.

The fan delay is designed to allow the heat exchanger to warm up before the fan blows air into the ducts. This helps increase efficiency and prevents cool air from being circulated initially. Once the heat exchanger reaches the set temperature, the fan will turn on to distribute warm air throughout the home.

1KG of transformer oil will sum up to 0.815litres.

A hot furnace emits primarily infrared radiation, which is a form of heat energy. This radiation is invisible to the human eye but can be felt as heat when in close proximity to the furnace.

First we add the basic iron production elements (i.e, limiston,coreand processed iron e.g hematite,Fe2O3 )

the coke is react with oxygen and form crbone monoxide

the limestone decomposed to CaO and carbon dioxide,CO2

carbondioxide,CO2 react with Fe2O3 to form Fe and CO

CaO (reaction flux) react with almunia and silica form slag

the Fe is removed as a molton ways below blast furnace and sage is removed anather ways,THANK YOU FOR READ

The height of blast furnaces is typically around 100 feet to create enough space for the chemical reactions to occur efficiently. The height allows for gravity to assist in the movement of materials through the furnace, aiding in the reduction of iron ore and the separation of molten iron from impurities. Additionally, a taller furnace enables better temperature distribution and facilitates the flow of hot gases for proper combustion.

A furnace coil is a component in a heating system that is responsible for converting electricity or fuel into heat. It consists of a coil of metal tubing through which a heat transfer fluid, such as air or water, flows to transfer the heat to the surrounding space. Furnace coils are commonly found in electric furnaces and boilers.

The size of the breaker for a furnace will depend on the specific requirements of the furnace unit. It is recommended to check the furnace's user manual or consult with a qualified electrician to determine the correct breaker size for your particular furnace model. Using the wrong size breaker can be a safety hazard.

Carbon refractories are used in blast furnaces because of their high resistance to heat and thermal shock. They can withstand the extreme temperatures and chemical reactions that occur during the iron-making process. Additionally, carbon refractories have good thermal conductivity, allowing them to efficiently transfer heat in the furnace.

Because they have fireplaces that need to vent to the exterior.

White smoke coming from a gas furnace can be caused by a few factors: a blocked flue or air intake, a cracked heat exchanger, or excess moisture in the combustion chamber. It is important to address this issue promptly as it can indicate a potentially dangerous problem with your furnace. It is recommended to shut off your furnace and contact a professional HVAC technician to inspect and repair the issue.

Thermostats should ideally be placed on an interior wall, away from drafts, direct sunlight, doorways, and windows. It is recommended to install them at least 5 feet away from heating and cooling sources, such as furnaces, to ensure accurate temperature readings and proper functioning of the HVAC system.

Yes, coal can be burned in a furnace to generate heat or electricity. When coal is burned, it releases energy in the form of heat which can then be used for various purposes. However, burning coal releases harmful emissions into the atmosphere, contributing to air pollution and climate change.

Limestone is added to the furnace as a flux to help remove impurities from the iron ore during the iron-making process. It reacts with the impurities to form slag, which can be easily removed from the molten iron.

Smoke moves in the chimney due to the difference in temperature and pressure between the inside and outside of the chimney. As hot air rises, it creates a draft that draws the smoke up and out of the chimney. The design of the chimney, including its height and width, can also impact how efficiently the smoke is expelled.

Home furnace flue gas should ideally be between 300-500 degrees Fahrenheit to help it rise up the chimney efficiently and safely without causing any harmful buildup or backdraft. Regular inspection and maintenance of the chimney and flue are recommended to ensure proper functioning.

Gold is typically found in its pure form in nature due to its inert nature and resistance to oxidation. In contrast, iron and aluminum are chemically reactive metals that form compounds with other elements, requiring extraction processes like smelting or electrolysis to isolate them from their respective ores.

The density of furnace oil at 120 degrees Celsius may vary depending on the specific composition of the oil. However, as a general estimate, the density of furnace oil at this temperature is typically around 0.9 - 0.95 grams per cubic centimeter.

The charge in the blast furnace typically consists of iron ore, coke (a form of coal), and limestone. The iron ore is the main source of iron, the coke provides the heat and reducing agent, while the limestone helps remove impurities in the form of slag.

It typically takes a few hours to produce iron in a blast furnace. The process involves loading the furnace with iron ore, coke, and limestone, heating it to high temperatures, and allowing the molten iron to collect at the bottom of the furnace. Once the iron is ready, it can be tapped and further processed into various forms.

A cupola furnace is not the same as a crucible furnace. A cupola furnace is a type of melting furnace used mainly for iron melting, while a crucible furnace is a type of melting furnace that uses a ceramic or graphite crucible to contain the molten metal. The names reflect the different structures and functions of the two types of furnaces.

The smell after cleaning a furnace could be due to dust and debris being stirred up during the cleaning process. It's also possible that a new filter or cleaning solution was used, which can emit a temporary odor as it circulates through the system. Typically, the smell should dissipate after a few hours as the furnace runs and the air circulates.

The buildup of soot and creosote from the chimney is often referred to as chimney residue or chimney deposits. This residue can be a fire hazard and should be regularly cleaned to maintain a safe and efficient chimney.

To install a coil into a furnace, first make sure the furnace is turned off and disconnected from power. Then remove the access panel and locate the existing coil. Carefully remove the old coil and install the new one by following the manufacturer's instructions, securing it in place, and reconnecting any necessary components before testing the furnace.

The temperature of a furnace can be measured using a thermocouple, which is a temperature sensor that produces a voltage proportional to the temperature. The thermocouple is placed inside the furnace and the voltage output is converted to a temperature reading by a controller or thermometer.
