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
What is the method to improve the effiecincy of duel fired boiler?
To improve the efficiency of a dual-fired boiler, one effective method is to optimize the combustion process by ensuring proper air-to-fuel ratios and enhancing the mixing of fuel and air. Implementing advanced control systems can help in adjusting parameters dynamically for varying load conditions. Additionally, regular maintenance, including cleaning and inspecting burners, can reduce fouling and ensure optimal performance. Incorporating heat recovery systems, such as economizers, can also capture waste heat and improve overall efficiency.
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"
What is duel fuel fired boiler?
Its a Boiler that is fitted with two or more heating sources. Say Gas and Oil Fired
What is a sky climber in a pf boiler?

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
