PC fired boilers do not have refractory covering on the furnace tubes or other heat transfer areas. With warming water temperatures will produce refractory materials that will boielr the oil in the water.

Comparison of Circulating Fluidized Bed Boiler and Pulverized Coal Boiler

In reheater system we use hot cyclone to improve the efficiency of boiler. Now these days have some boiler have both feeding system.

The granular refractory materials are mixed with water.

What is diffrent boller afbc and cfbc boiler? The water and steam circuit, the natural circulation of water and heat transfer surfaces are all the same in both the systems.

What is the function of cyclone in cfbc boiler?


What is the Difference Between AFBC and CFBC Boiler

In compared with under feeding system this is more reliable. It works with the help of diffrential pressure.

Difference between hot cyclone and cold cyclone in cfbc? For 3-pass boiler we … are used hot cyclone. CFBC signifies “Chemical engineering circulating fluid-bed combustion,” and is often used in power plants. What is afbc boiler? Choose a video to embed. In a AFBC boiler a little more fluidized bedcombustor is added than a conventional sh … ell boiler.

Split and merge into it. Refractory materials are heated in water to take it. What is the purpose of phosphate dosing in AFBC boilers?

With warming water temperatures will produce refractory materials that will ignite the oil in the wa … ter. Working of cfbc boiler? Boilers that utilize fluid-bed combustion burn fuels at lower temperatures are more efficient and betweeen burn fuels other than coal. Would you like to make it the primary and merge this question into it?

CFBC boiler process and their advantage over AFBC boiler – ASKPOWERPLANT

In over b … ed system coal is carried by conveyer belt from bunker to spreader that’s time coal size approx mm crushed. Circulating fluidised bed combustion. CFB uses coal crushed to sizes of around 3 to 6 mm. To boi,er this erosion a thin layer of refractory covers the lower half of the furnace, upper transition areas and the cyclone.


There is the difference in the pressure of air beteen … furnace and return leg. Main difference between hot cyclone wfbc cold cyclone is 1.

Comparison of Circulating Fluidized Bed Boiler and Pulverized Coal Boiler

How do you lightup afbc boiler? In betweeb cyclone flue gas temperature is above ‘c. The steam comes out horizontally. This requires only a simple limestone storage and handling unit. Generally the Phosphate dozing is done in the drum of the boiler. What is cfbc boiler? The total air for combustion and the balanced draught system is the same in both the systems.

CFBC boiler operation procedure? PC firing utilises coal ground to a very fine powder sprayed into the furnace for combustion. The furnace and the cyclones in the CFB boilers are subject to a lot of erosion due to the circulation of particles like ash and sand.
