What are the advantages and disadvantages of circulating fluidized bed boilers! In the past, the application is the traditional pulverized coal furnace boiler, with the continuous development of industry, human awareness of environmental protection is more and more strong, many enterprises are gradually applied to the circulating fluidized Disadvantages of Pulverized Coal Firing The initial investment in pulverized coal firing system is more compared to solid firing system The running cost is also higher The pulverized coal produces fly ashes Removal of ash grain from the exhaust gases is always expensive as it requires an electrostatic precipitatorPulverized Fuel Firing of Boiler Electrical4U Advantages and disadvantages The performance of an IGCC is compared to the highly efficient Natural gas fired combined cycle and the Ultra Supercritical pulverised coal fired plants The overall thermal efficiency of the IGCC power plant is almost same with that of an Ultra supercritical coal fired power plant but still less than an Natural Comparison of Gasification Combined Cycle Power
Thermal Power Plant Working, Layout and
The mixture of pulverized coal and air (usually preheated air) is taken into the boiler and then burnt in the combustion zone On ignition of the fuel, a large fireball is formed at the center of the boiler and a large amount of heat energy is radiated from it Advantages and Disadvantages of Thermal Power Plant Advantages: Less initial Pulverized coal can utilize highly preheated air (of the order of 370°C) successfully which promotes rapid flame propagation As the fuel pulverizing equipment is located outside the furnace, therefore it can be repaired without cooling the unit down High temperature can be produced in the furnace Disadvantages: Using pulverized coal has the Ball and Race Mill ~ ME Mechanical Circulating Fluidized Bed (CFB) combustion boilers gives the flexibility for combustion of a wide range of coals and alternative fuel sources All this without compromising efficiency and with reduced emissions The advantages of the CFB boiler over the conventional boiler systems are explained in this articleThe most important advantage of the CFB is the flexibility of firing a wide range of Circulating Fluidized Bed Boilers Advantages Bright
