Description
Technical field
The utility model relates to fluidized bed furnace, particularly the efficient fluidized bed furnace of a kind of double-jacket.
Background technology
At present, when mounted, need design a concrete platform, furnace wall drops on concrete beam plate fluidized bed furnace, and furnace wall is generally by internal layer alumina firebrick, and the scenes such as interlayer perlite is heat insulation, outer clean water red brick wall insulation are built by laying bricks or stones and formed.The thickness of furnace wall is mostly more than 500, very heavy, therefore there are certain requirements the load-bearing of beam slab.The expense of civil engineering is often invested larger.In some small-sized flue gas heating systems, high level or the place that can not do concrete platform because place is limited, locally do not allow the place using clayey insulation material, the application of traditional fluidized bed furnace will be restricted.
Summary of the invention
The purpose of this utility model is improved for above shortcoming exactly, provides a kind of structure simple, lightweight, easy for installation, the efficient fluidized bed furnace of the double-jacket that the thermal efficiency is high.
The efficient fluidized bed furnace of the utility model double-jacket, there is body of heater, body of heater inner surface is provided with flame retardant coating, the top of body of heater is provided with outlet flue, the bottom of body of heater is provided with air inlet and slag emission mouth, body of heater is provided with fuel-feed pipe, it is characterized in that: described body of heater adopts cylinder-shaped steel structure, body of heater is double-deck, inner barrel and outer cylinder body, inner barrel is arranged in the middle and lower part of outer cylinder body, arranges secondary air-inlet channel between inner barrel and outer cylinder body, the bottom of outer cylinder body is provided with secondary air inlet, and secondary air inlet is connected with secondary air duct.
The efficient fluidized bed furnace of described double-jacket, is characterized in that: the external wall of upper portion of described inner barrel is provided with spiral flow deflector, and spiral flow deflector and outer cylinder body inwall form spiral air intake passage; Both Secondary Air can have been allowed to flow into equably, the effect of reinforcement can also have been played.
The utility model structure is simple, lightweight, easy for installation, thermal effect is high, and the secondary air duct between inner barrel and outer cylinder body both can play a part to cool inner barrel, can play again the object of air distribution temperature adjustment, the effect supporting fixing inner barrel can also be played, the utility model is applicable to small-sized flue gas heating system, high level or the place can not doing concrete platform because place is limited, also can be used for the local place not allowing to use clayey insulation material.
