Why is coal crushed and ground into a fine powder before it is blown into the boiler furnaces?
Coal is crushed and ground into a fine powder before being blown into boiler furnaces primarily to improve combustion efficiency. Here's why: Increased Surface Area: When coal is ground into a fine powder, its surface area increases dramatically. This allows it to burn much more quickly and completely when mixed with air. Faster Combustion: Fine coal particles ignite faster than larger chunks. This ensures that the coal burns rapidly and releases heat more efficiently, which is essential for power generation. Better Temperature Control: Pulverized coal allows for better regulation of furnace temperatures, improving the overall stability and efficiency of the boiler. Reduced Unburnt Residue: Finely ground coal ensures more complete combustion, which reduces the amount of unburnt carbon in the ash and lowers waste. Improved Heat Transfer: Complete and efficient burning of pulverized coal produces a consistent and intense flame, which enhances the heat transfer to the boiler tubes, producing steam more effectively. In short, pulverizing coal makes the combustion process more efficient, cleaner, and better suited for large-scale power generation. 4o
Why is coal broken and grounded into powder before it is blown into the boiler blast furnice?
The fine coal dust is much more combustible than large lumps of coal. Large lumps of coal takes time for the flames to begin burning it efficiently - so heat takes longer to build up in the furnace.
What is the PH value in boiler feed water?
The pH value in boiler feed water is typically maintained between 8.5 and 9.5. This range helps to prevent corrosion and scaling in the boiler system. Regular monitoring and adjustment of pH levels are important to ensure the proper functioning and longevity of the boiler.
What is the effect of chloride in boiler?
Chloride in a boiler can lead to corrosion and scale formation. Excessive chloride levels can accelerate the degradation of boiler components, reducing their lifespan and efficiency. It is important to monitor and control chloride levels to prevent damage to the boiler system.
Why is hard water not used in a boiler?
Sea water, as from oceans, is salty. If used in a boiler the salt will deposit as scaling, which is a bad thing. It's also more corrosive, so the boiler and all associated pipework will rust out faster.
Is boiler and furnace are same?
No, furnaces are forced air heat. Boilers are hot water heat.
What are the main types of furnaces?
The main types of furnaces include forced air, boiler, and electric furnaces. Forced air furnaces use a blower to distribute heated air throughout the home, while boiler systems heat water to produce steam or hot water for heating. Electric furnaces convert electricity into heat and are often used in smaller spaces or as supplemental heating. Each type has its advantages and is suited for different heating needs and energy sources.
What is an alternative to a gas boiler when a person is looking at furnaces?
Electric heating boilers can be a useful alternative to gas and other conventional furnaces. LPG and oil-fired boilers are also very efficient. Biomass boilers are also becoming popular.
Did the Titanic have 10 engines?
Titanic had steam made by 29 boilers in six boiler rooms, which contained 159 coal burning furnaces fueling the boilers.
How many engines are in the Titanic?
Titanic had steam made by 29 boilers in six boiler rooms, which contained 159 coal burning furnaces fueling the boilers.
Which funnel was the 4th one on the titanic?
The first three funnels were connected to the boiler room and its 29 scotch type furnaces. The last one (at the stern) was the false one
How many main engines were there on the Titanic?
Titanic had steam made by 29 boilers in six boiler rooms, which contained 159 coal burning furnaces fueling the boilers.
How many boilers did Titanic have?
there were around 29 boilers divided into 6 boiler rooms. the boilers were 15-foot-high. and provided the ship with steam.
What companies make wood burning furnaces?
