2) The simple introduction of **0MW class Circulating Fluidized Bed (CFB) Boiler
• Main steam flow：**0~**0t/h
• Main steam outlet temperature/pressure：**0℃/9.*1~*2.8MPa.g 
• Feed water temperature：**0~**2℃
Technical features：circulating fluidized bed firing, M-type arrang- ement, single furnace, without external bed heat exchanger, single flue duct in the tail, cyclone separator, coal and limestone feeding at front wall, bell-type air cap, upon -bed ignition, roller ash cooler, etc. 
Boiler advantages：extensive fuel adaptability range ( applicable for firing petroleum coke, biomass fuel such as bark, widely used in chemical and paper making industries ), high efficiency of in-boiler desulphurization, low capital and operation cost, low NOx emission, high combustion efficiency, excellent regulation features for steam temperature, simple system configuration, high load regulation ratio, comprehensive utilization of ash and slag. 

3) Design standard and selection scheme of main and auxiliary equipment of boiler island 



The scope of supply for each unit is as follows (taking CFB boiler island project as an example):

S.N.    System    Main equipment

1    Boiler proper    Steam drum, air heater, soot blower, refractory material, cyclone separator, air preheater

2    Coal feeding system    Coal silo, coal feeder, coal chute

3    Limestone system    Limestone silo, rotary feeder, bellows, limestone pipeline

4    Startup bed material system    Bed material silo, bucket elevator, bed material pipeline

5    Air/gas system    Primary air fan, secondary air fan, induced draft fan, high-pressure fluidized air fan, air fan motor, fan silencer, air/gas duct

6    Oil firing system    Start-up burner, high-energy igniter, oil pipe, filter

7    Dedusting system    Bag dust collector

8    Desulphurization system    Absorption tower, process water tank, booster fan, limestone slurry tank, filtrate tank

9    Denitration system    Reactor, pressure-stabilizing trough, ammonia evaporator, ammonia mixer, dilution fan

 

Remark: All the systems and equipment listed in the table include three parts, i.e. mechanical, I&C, and electrical parts.
