Difference Between AFBC And CFBC Boilers. AFBC means atmospheric fluidized bed combustion, where the furnace pressure is. The difference between the mean Almost all AFBC/ bubbling bed boilers use in -bed evaporator tubes in the bed of limestone, sand and fuel for . For large units , the taller furnace characteristics of CFBC boiler offers better space utilisation. Dear all, please tell me what is different between AFBC BOILER amp CFBC BOILER.

The heated precipitate coming in direct contact with the tubes heating by conduction increases the efficiency. The second reason, which has become increasingly important, is the possibility of achieving, during combustion, a low emission of nitric oxides and the possibility of removing sulfur in a simple manner by using limestone as bed material.

With warming water temperatures will produce refractory materials that will ignite the oil in the water. The multi-pointwater heater provides hot water cbc multiple appliances or taps atthe same time.

A fire acbc boiler has a watertight outer jacket with tubes through the center of it. The heating of boiler parts is not uniform, so, there are chances of differential expansion of parts and hence chances of cracks are maximum. If the energy input to the cycle is kept constant, the output can be increased by selecting elevated pressures and temperatures for the water-steam cycle. References in periodicals archive?
