In recent decades,with the increasing demand of energy conservation and environmental protection in industrial production,the higher requirements about boiler combustion technology and fuel have been put forward.Therefore,the circulating fluidized bed boiler emerged and is being developed rapidly.After the purchase,the primary problem is the installation,the boiler installation is directly related to the subsequent usage,this paper will introduce the installation considerations about the boiler in the following sections:
Circulating fluidized bed boiler steel frame installation
Before the construction,we should arrange the installation sequence of the steel frame,the horizontal beams between the furnace wall and inertial separation wall and the horizontal beams on the north side of the boiler don’t install temporarily,avoiding affecting the hoisting of water wall tubes and other parts.
Circulating fluidized bed boiler drum installation
Before installing the drum,we must ensure that the parallelism between the two bearings of drum,the bearing elevation and levelness meet the design requirements.
Circulating fluidized bed boiler membrane Wall installation
Before lifting,the components of different stiffness and strength should be reinforced to prevent the deformation,the reinforcement methods commonly used are: section-steel reinforcement, steel reinforcement,truss beam reinforcement truss girder,the concrete reinforcement measures can be determine according to site conditions.
Circulating fluidized bed boiler sealing device installation
All sealing element must continuously welded,there cannot be broken welding and welding leakage phenomenon.
Circulating fluidized bed boiler cyclone separator installation
Because the cyclone separator is bulk items,they need to be assembled at the scene,among them,the cone cylindrical shell section is most difficult to assemble,before assembling,its arc and taper degree
