Differences between afbc and cfbc boilers?
(fbc) boiler to heat the Water that is mixed with a refractory material. With warming water temperatures will produce refractory materials that will ignite the oil in the water. The granular refractory materials are mixed with water. Refractory materials are heated in water to take it. c) boiler column. The steam comes out vertically. A) horizontal boiler. The steam comes out horizontally.
Why loop seal provided in cfbc boiler?
loop seal is provided to stop the material from furnace to return leg back.It works with the help of diffrential pressure.There is the difference in the pressure of air beteen furnace and return leg.
What function job boiler man operator?
a boiler operator should know and be capable to run it smoothlyt
What is function of boiler circulating pump in boiler?
The boiler circulating pump is essential for maintaining the flow of water or steam within the boiler system. Its primary function is to circulate water from the boiler to the heat exchanger and back, ensuring efficient heat transfer and maintaining the desired temperature and pressure levels. This circulation helps prevent overheating and ensures uniform heating throughout the system, contributing to overall operational efficiency and safety.
What is the function of back pressure valve in Boiler feed pump?
The function of back pressure valve is to prevent back flow to the pump in case there is an obstruction on downstream side of valve.
Difference between hot cyclone and cold cyclone in cfbc?
Main difference between hot cyclone and cold cyclone is 1. In hot cyclone flue gas temperature is above 800'c., in cold cyclone is is 400 to 500'c. 2. For 3-pass boiler we are used hot cyclone. 3. In reheater system we use hot cyclone to improve the efficiency of boiler.
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.
Function of root blower in cfbc boiler?
the pressure of the root blower is higher then the wind box pressure, because what ever the unburnt particle come from cyclone separator is collect in return leg this unburnt particle return back into combustion chamber so the function of root blower is to continuous circulation.
Cfbc boiler full form?
Circulating fluidised bed combustion
What is the meaning of cfbc boiler?
The boiler in which fluidisation and combustion is done in the bed with the help of (pa,sa&ta)air and ash(un burnt particle) is re-used through cyclone and siphone to the bed is called cfbc boiler.
What is differential pressure in cfbc boiler?
Differential pressure in a Circulating Fluidized Bed Combustion (CFBC) boiler refers to the difference in pressure between two points within the system, typically across the bed of the boiler. This pressure difference is crucial for maintaining the proper flow of gas and solid particles, ensuring efficient combustion and heat transfer. Monitoring differential pressure helps in optimizing the operation of the boiler, as it can indicate changes in bed density, flow resistance, or potential blockages. Maintaining the appropriate differential pressure is essential for the overall performance and efficiency of the CFBC boiler.
How do you calculate coal consumption in afbc boiler?
how we calculate the coal consumed to generate xxx MW say 12 hrs or 24 hrs in CFBC boiler please help
CFBC boiler operation procedure?
drum level maintain at48to52% O2 4% id draft _2to+2
What is PA Fan discharge pressure and bed height maintained in IR CFBC boiler?
1300 mmWc @ full load
What is the purpose of wall seal blower in cfbc boiler?
The wall seal blower in a Circulating Fluidized Bed Combustion (CFBC) boiler serves to maintain a proper seal between the combustion chamber and the external environment. By creating a slight negative pressure, it prevents the escape of flue gases and ensures efficient combustion by maintaining the required airflow. Additionally, it helps to enhance the overall efficiency of the boiler by optimizing the circulation of the bed material and improving the combustion process.
What is wing wall super heater in cfbc boiler?
A wing wall super heater in a Circulating Fluidized Bed Combustion (CFBC) boiler is an arrangement designed to enhance the temperature of steam produced in the boiler. It consists of tubes arranged along the side walls of the furnace, where hot flue gases from the combustion process pass over them. This setup increases the efficiency of steam generation by utilizing the high-temperature gases, thereby improving the overall thermal performance of the boiler. The design helps to reduce temperature gradients and optimize heat transfer.
What are the boiler parts and function?
steam boiler
