What is DP test in Afbc boiler?
8-What do you mean by DP test in AFBC Boilers? It is the test carried out before the light up of Boiler to ensure the healthiness of air nozzle & bed plate.
What is the difference between CFBC and Afbc boiler?
CFBC boilers are said to achieve better calcium to sulphur utilisation – 1.5 to 1 vs. 3.2 to 1 for the AFBC boilers, although the furnace temperatures are almost the same. CFBC boilers are generally claimed to be more economical than AFBC boilers for industrial application requiring more than 75 – 100 T/hr of steam.
How does Afbc boiler work?
The AFBC Boiler achieves this by carrying out combustion in a bed of crushed refractory / sand which is suspended by an upward stream of air, fluidising it and facilitating a significant higher degree of combustion completeness.
How do you light a boiler?
How do you relight the pilot light on a boiler?
- Turn the gas to ‘pilot. ‘
- Press and hold the reset switch for one minute and hold a flame to the pilot light at the same time.
- If all is working as expected, return any casing/doors and turn the gas from ‘pilot’ to ‘on.
What is the full form of Afbc?
Atmospheric Fluidised Bed Combustion(AFBC)
What is bed height in boiler?
250 to 300mm
BED HEIGHT / FD AIR PRESSURE • Static height for AFBC boiler is to be maintained 250 to 300mm during initial light up of boiler. Expand bed height for AFBC boiler is to be maintained 500 to 600 mmwc.
Why bed material is used in boiler?
The purpose of Bed Material is to support Fluidization of the Bed. It is little heavier (higher gravity) and rounded spherical shaped sand allowing uniform primary air distribution for good fluidization and at the same time ensuring excellent turbulence for combustion with minimum excess air.
What is TPH in capacity?
TPH =Tonnes per hour.
Why it is called Afbc boiler?
The bubbling type AFBC boiler offers efficient, cost-effective, reliable and viable alternative to conventional solid fuel-fired boilers for industrial applications.
What does Afbc stand for?
Acronym. Definition. AFBC. Atmospheric Fluidized-Bed Combustion (power generation, associated with coal-fired power plants)
How do I light the pilot on my boiler?
Furnace – How to Relight a Pilot Light | Repair and Replace – YouTube
Why is my boiler not igniting?
If the boiler is not igniting, there is a possibility the valve is blocked, seized or there is damage in the wired connections. No Pilot Light: When the boiler is not igniting and the pilot light has gone out, this usually means debris has blocked the jet.
What is PF boiler?
A pulverized coal-fired boiler is an industrial or utility boiler that generates thermal energy by burning pulverized coal (also known as powdered coal or coal dust since it is as fine as face powder in cosmetic makeup) that is blown into the firebox.
What is boiler efficiency formula?
η=(Energy output)/(Energy input) X 100
In order to calculate boiler efficiency, we divide the total energy output by total energy input, multiplied by hundred.
Why sand is used in boiler?
Boiler sands are used in power plants utilizing fluidized bed technology to form a firing grate. The purpose of boiler sands is to form a sand bed in the boiler, which allows the fuel fed into the boiler to burn on top of and within this layer of bed material.
How is boiler TPH calculated?
Super heater safety valve relieving capacity at full open condition in TPH = Boiler MCR X 36–38%…….Ex: 125 TPH Boiler has SH safety valve of relieving capacity = (125 X 36/100) = 45 TPH.

Why bed material is used in Afbc boiler?
Refractory Bed Material for AFBC and CFBC boilers is a very exclusive refractory product, processed from special refractory aggregates of high chemical purity, dense consistency, high refractoriness, etc., and is suitable to sustain technical properties for fluidization at high temperatures of 14000 C with different …
How do I relight my pilot light?
How to Relight a Water-Heater Pilot Light – YouTube
Can you manually ignite a boiler?
There are two types of boiler pilot lights. One is a manual type that you must light, and the other is an automatic pilot ignition type that lights itself. Before lighting any boiler, you must know which type you have; there are two ways to determine this.
How do I get the pilot light back on my boiler?
How to Relight a Pilot Light: 5 Easy Steps
- Find the pilot light assembly and its reset switch. The furnace’s pilot light is usually positioned at the bottom of the unit by a knob.
- Set the reset switch to off. Turn the knob to the “Off” setting.
- Wait a moment.
- Relight the pilot light.
- Observe the furnace.
Which coal is used in boiler?
Bituminous Coal
Bituminous Coal: This offers advantages of high heating content and enough volatiles to ignite quickly in a boiler, with the propensity to a severe case of spontaneous combustion.
What is boiler capacity?
Since the amount of steam delivered varies with temperature and pressure, a common expression of the boiler capacity is the heat transferred over time expressed as British Thermal Units per hour. A boilers capacity is usually expressed as kBtu/hour (1000 Btu/hour) and can be calculated as. W = (hg – hf) m (1)
How do I calculate boiler output?
Multiply the temperature rise by the water’s weight in kilograms, which is equivalent to its volume in liters. For example, if the boiler contains 100 liters of water, multiplying 30 by 100 gives 3,000.
