The Chimney Rock National Monument in Colorado has 200 steps leading to the top of the mesa where the ruins are located. These steps offer a challenging but rewarding hike with stunning views along the way.

A cupola furnace is a tall, vertical furnace used to melt iron and other metals. It works by charging alternate layers of metal and coke (carbon fuel) through a charging door at the top of the furnace. The coke is ignited, creating intense heat that melts the metal charge, which is tapped periodically from the base of the furnace.

It isn't actually duck tape, but duct tape. The rubberized fabric was originally used to seal the flexible metal "ducts" (conduits) that carry heated or cooled air (or vent air) within a building.

no it is not they are totally different kinds of tape. duck tape tape is much stronger that electric tape.

Alice H. Parker was indeed an important inventor who patented a gas-powered central heating furnace in 1919. The lack of widespread recognition for her may be due to historical biases that have often marginalized or overlooked the contributions of women and minority inventors. Efforts to highlight her achievements and those of other underrepresented inventors are ongoing.

In "Native Son," the furnace and heat symbolize the oppressive and suffocating environment that Bigger Thomas lives in, both physically and emotionally. The furnace represents the relentless heat of institutional racism and poverty that Bigger cannot escape, leading to his feelings of confinement and desperation. The heat also serves as a metaphor for the intense pressure and tension that Bigger experiences as he navigates a hostile society that restricts his opportunities and humanity.

In the novel "Out of This Furnace," Mary Dobrejcak dies from tuberculosis.

Zinkoff decides to face the Furnace monster because he wants to prove to himself that he is brave and capable. By confronting his fear, he is able to show his inner strength and courage.

Children chimney sweeps in the 18th and 19th centuries typically received very low wages, often as little as a few pennies or a small amount of food per job. Many were subjected to harsh working conditions and exploitation by their masters.

In the UK, laws were passed in the mid-19th century to abolish child labor in hazardous industries such as chimney sweeping. The Chimney Sweepers Act of 1875 made it illegal for children under the age of 21 to be apprenticed into chimney sweeping. This effectively ended the practice of child chimney sweeps.

"Escape from Furnace" is set in a dystopian future, where the main character is imprisoned in an underground penitentiary known as Furnace Penitentiary. The exact time period is not specified, but it appears to be in a distant future where the government has implemented extreme measures to deal with crime and punishment.

Little Tom Dacre is crying because he has a dream in which he sees all the chimney sweepers, including himself, being released from their suffering and going to a place of joy and freedom. This dream contrasts with the harsh reality of their actual lives as chimney sweepers, which is filled with exploitation and hardship.

Child chimney sweeps began to decline in the mid-19th century with the introduction of new labor laws and regulations aimed at protecting children from exploitation. The use of child chimney sweeps officially ended in the early 1870s with the passage of legislation such as the Chimney Sweepers Act of 1875 in the UK.

King Nebuchadnezzar of Babylon threw Shadrach, Meshach, and Abednego into the fiery furnace as punishment for not bowing down to his golden image.

the Coke supplies carbon monoxide to reduce the ore in a blast furnace and supplies heat to melt the iron.

To remove impurities, mainly sand ( silicon dioxide). It is sometimes reflerred to as a 'flux'.

The limestone undergoes thermal decomposition.

CaCO3 = CaO + CO2

The CO2 reacts with the coke to produce carbon monoxide

CO2 + C = 2CO

The Carbon monoxide reduces the iron ore ( iron oxide) to iron

Fe2O3 + 3CO = 2Fe + 3CO2

The iron is tapped off at base of the furnace. The CO2 recircluates to form more carbon monoixide.

The Iron ore contains a number of impurities , notably sand (silicon dioxde ; SiO2)

These impurities react with calcium oxide (CaO) produces from the thermal decomposition of ;omestone, to form 'slag'.

CaO + SiO2 = CaSiO3 (calcium silicate (Slag)).

Since tons of slag is produced it is used to make 'breeze blocks' for building and road surfaces.

Sinter, which is a mixture of iron ore, coke and limestone, and a blast of hot air.

Externally to the furnace, iron ore, coke and limestone are mixed together Intimate mixing ensures that the reactants are as close as possible to each other. This is loaded into the top of the blast furnace.

A blast of hot air ( ~ 1100 oC) is sent in at the bottom of the furnace, through tuyeres. The oxygen (air) is also one of the reactants.

The products are tapped from the bottom of the furb=nace are liquid iron and 'slag' ( calcium silicate).

To install a furnace in a house with a crawl space, follow these steps:

Assess the Crawl Space: Before installing the furnace, inspect the crawl space for any signs of moisture or damage. Ensure proper ventilation by checking and, if necessary, installing crawl space vents to promote airflow and prevent moisture buildup.

Prepare the Area: Clear the crawl space of any debris or obstacles to create a suitable workspace for installation. Ensure there is adequate space for the furnace unit and access for maintenance.

Install Ductwork: If the house doesn't already have ductwork in the crawl space, install it to connect the furnace to the rest of the HVAC system. Seal all duct joints properly to prevent air leaks.

Position the Furnace: Choose a suitable location for the furnace within the crawl space, considering factors such as accessibility, clearance requirements, and proximity to existing ductwork.

Secure the Furnace: Once the furnace is in position, securely mount it according to the manufacturer's instructions. Ensure it is level and stable to prevent any movement or vibration during operation.

Connect Utilities: Connect the furnace to the power supply and fuel source, whether it's gas, oil, or electricity. Follow local building codes and safety guidelines when making these connections.

Test and Commission: After installation, test the furnace to ensure it functions correctly. Check for any leaks, unusual noises, or malfunctions. Once everything is in working order, commission the furnace for regular use.

By following these steps and ensuring proper ventilation with crawl space vents, you can successfully install a furnace in a house with a crawl space while maintaining a safe and efficient HVAC system.

The man ran into the hot furnace to save the boy that was stuck in there.

The refining process is actually a REDUCTION process.

The iron ore ( oxidised iron ) is reduced in the Blast Furnace to IRON.

Three substances are mixed and added to the Blast Furnace.

They are Iron Ore (Iron(III) Oxide ; Fe2O3)

Coke (Carbon ; C)

Limestone ( Calcium carbonate ; CaCO3)

A Blast of Hot Air is sent in from the bottom (O2)

The heat makes the limestone decompose to calcium oxide(CaO) and carbon dioxide(CO2)

The Carbon then reacts with the carbon dioxide and also the air to form carbon monoxide.

CO2 + C = 2CO & "C + O2 = 2CO (4CO)

It is the Carbon Monoxide (CO) that reacts with iron ore to form iron. as carbon monoxide is a powerful reducing agent.

2Fe2O3 + 4CO = 4Fe + 4CO2 (Not Balanced)

As a secondary reaction the calcium oxide reacts with the impurities in the iron oxide (viz. sand ; SiO2) to form 'slag' (calcium silicate) .

CaO + SiO2 = CaSiO3 (slag).

Calcium silicate is used top make road surfaces, and 'breeze' blocks for building.

The iron that is collected is still impure, and whilst liquid hot, is placed in a BOS plant with an oxygen lance, to oxidise any remaining impurities, viz. sulphur, (to sulphur dioxide) and phosphorus(to Phosphorus oxide). The carbon impurity ( to carbon dioxide) is controlled at this stage in order to make steel , which contains about 0.1% to 2% carbon , depending on the nature of the steel.

thermostat is commonly used to regulate the heat of a furnace. It can programmed to maintain a desired temperature by turning the furnace on or off as needed. Some thermostats have additional features such WiFi connectivity, smart home integration, and scheduling options.

Victorian Children who were poor worked not only as chimney sweepers many times 16 hours a day, but also in factories, farms, mines, maids, horse dung removers on the streets, went off to sea, and any jobs that required small, little hands and bodies.

well I live some place where bats love go and it has never happened.

so no.

It means you should install a screen on your chimney to keep it from happening again.

possible gas leak. leave home immediately, call gas company from neighbors house. do not turn on or off switches. do not call from your house. better safe than sorry. I am a licenced gas technician. good luck.
