For getting better efficiency from boiler, coal is pulverized in mills (powder form)
before entering into boiler along with hot air. This is done in order to control
damage to boiler tubes and plates due to high (but cheap) sulphur content
in coal. These types of boiler are usually called super critical boiler and
works on high pressure (3600psi) and temperature (610 degree C)
unlike sub critical boilers.

What is a tangentially fired boiler?
A tangentially fired boiler has between 4 and 8 burners, placed in the corners of the boiler. These are sometimes angled vertically to maximize impingement of the flames. They are fired into the center of the boiler, not directly into the center, but at the wall to adjacent to them. This causes the flames to swirl inside of the boiler, causing an even distribution of flame throughout the boiler. This is shown pretty well here: http://www.alstom.com/power/coal-oil/utility-boilers/firing-systems This website also has a lot more detail than previously provided.
What is the advantage of afbc boiler over pf boiler?
afbc has high turn down ratio,burner arrangement is simple,low grade coal can be burnt efficiently,so2 emission can be controlled,
What is the difference in Boiler efficiency between CFBC Boiler and PF Boiler while firing powdery coal -50 percent less than 5 mm size?
Cfbc stands for circulating fludised bed combustion where as afbc is for atmospheric fluidise bed combustion afbc bed fluidising velocity is approx 4 m/s and in cfbc boiler fluidising velocity is 9-10 m/s. cfbc having low SOx & NOx comparative with afbc cfbc having higher efficiency up to 98.5 % then afbc boiler,cfbc boiler power consumption is more comparative to afbc.
What is boiler corrosion?
the decay of boiler material by chemical or electrochemical attack by its environment is known as boiler corrosion
How do you prevent boiler explosion?
All boilers are made to a pressure specification and in most countries any pressure vessel over a certain size is required to be periodically inspected and pressure tested to ensure it is fit for purpose. In addition to being in sound condition, the boiler is also expected to have some form of pressure relief valve. This is of sufficient size to vent off excess pressure before it gets to an explosive situation. It is obviously important that the pressure of this device is set to a lower level than the ultimate pressure specification of the boiler. Even quite small boilers, like those in coffee makers need to be inspected. Some boilers are 'gas fired' such as home heating boilers. These have a device called a thermocouple that detects the flame and is linked to the gas valve. If the flame goes out, or the burner does not ignite when gas is released in the boiler, it will shut the gas off. Typically gas fired boilers have a number of devices that will shut off the gas in the event that something doesn't work. This means that if the gas supply pipe is in sound condition, the boiler itself cannot leak gas and cause an explosion.
What is a fired boiler?
Well when I hear the word "Fired" used in reference to a boiler, it is used to describe the type of fuel used to heat the boiler (to fire it) such as a "Coal fired" or "Gas fired"

How does a gas boiler work and what is it used for?
A gas fired boiler is a product used to heat your water for homes as well as swimming pools, they are very ifficient and save energy thus lowering your electric bill. There is a down side to having a gas fired boiler being as the costs of gases has gone up greatly it would be harder to keep a gas fired boiler going for a middle class person
