Description
Technical field
This utility model relates to boiler plant technical field, particularly relates to a kind of cycles, economized fluidized-bed combustion boiler.
Background technology
CFBB uses single drum, natural circulation mode, is divided into front portion and two vertical shafts of afterbody generally.Anterior vertical shaft is for always to hang structure, and surrounding is made up of fin panel casing.From bottom to top, air compartment, emulsion zone, a dilute-phase zone it are followed successively by.Tail vertical well uses supporting construction, is connected by vertical cyclone separator between two vertical shafts, and separator bottom couples loop back device and ash cooler.Combustor and separator interior are equipped with abrasionproof liner, anterior vertical shaft Ao's pipe furnace wall, external metal casing, tail vertical well light boiler setting, eight steel columns bear boiler total weight.CFBB mainly uses high-ash inferior fuel, coal is after hearth combustion, substantial amounts of grey particle is carried to upper furnace by flue gas, a part of thicker grey particle is separated by separator and continues to send burner hearth back to, the grey particle that another part is thinner can not be trapped by separator and escape, with flue gas to tail vertical well, tail vertical well lining is equipped with the heat exchanger components such as high temperature superheater, reheater, low temperature superheater, economizer, air preheater；This part fine ash particle all can cohere on the heat exchanger components such as high temperature superheater, reheater, low temperature superheater, economizer, air preheater due to a variety of causes, and this phenomenon is " dust stratification "；" dust stratification " can make the heat exchange efficiency of these heat exchanger components be greatly lowered, and even loses heat exchange function, so that boiler output reduces, efficiency reduces.Generation in order to avoid " dust stratification " phenomenon; boiler factory would generally use various soot blower to carry out deashing process; as: steam sootblower, acoustic wave ash ejector, gas explosion pulse soot blower, pulse of compressed air soot blower etc.; along with gradually coming into operation of these soot blowers; the situation making dust stratification considerably reduces, and serves good soot blowing effect.Especially for the grey particle that those cohesivenesses are less, effect is especially pronounced.But, prolongation along with the time of use, the defect of various soot blowers is also completely exposed, such as steam sootblower soot blowing, blowing less than high temperature superheater, reheater, low temperature superheater, economizer, the ash at these heat exchanger components of air preheater tube bank center, at the end of soot blowing, steam can condense into water and flow to flue by ash blowing mouth, make ash be set on the pipe of these heat exchanger components cannot remove, cause tube failure；And for example pulse of compressed air soot blower soot blowing, if the intensity of pulse is excessive, the sealing that will make furnace wall wrecks, the healthy of neighbouring personnel is also had an impact simultaneously, therefore, pulse of compressed air soot blower is owing to being limited by pulse strength and impulse wave frequency, and the effect of soot blowing is had a greatly reduced quality.Further, both soot blowers need to consume mass energy, and energy consumption is higher.
Publication No. CN203309892U, publication date is that the Chinese patent literature on November 27th, 2013 discloses a kind of high-efficiency energy-saving circulating fluidized-bed combustion boiler, it is characterized in that: vertically the rear portion of down pass is disposed with vertical updraught flue, the outlet of burner hearth connects with the upper end entrance of described vertical down pass, the smokestack improving the tangential flow velocity of flue gas is arranged between described vertical down pass and described vertical updraught flue, it is disposed with high-temperature separator in described vertical updraught flue, the outlet upper end of described vertical updraught flue is connected with described superheater, described vertical down pass and vertical updraught flue bottom are provided with ash-pit, described ash-pit is provided with the returning charge mouth connected with described burner hearth.
High-efficiency energy-saving circulating fluidized-bed combustion boiler disclosed in this patent documentation, after using a period of time, easy dust stratification on high-temperature separator, superheater, heat exchange efficiency is caused to be greatly lowered, even losing heat exchange function, cause whole CFBB to be exerted oneself reduction, efficiency reduces.
Publication No. CN203147750U, publication date is that the Chinese patent literature of on 08 21st, 2013 discloses a kind of energy-efficient double speed CFBB, combustor, heat pipe, blast cap it is provided with in furnace chamber, combustor connects flue, flue is provided with heat exchanger and economizer, it is characterised in that: combustor is separated into high speed bed combustor and funnel shaped low speed bed combustor by barrier film, and both communicate by upper and lower side, low speed bed combustor is positioned at flue side, and blast cap is positioned at below high speed bed combustor；Being provided with air preheater in flue, one time air channel, secondary air duct flow through air preheater, and air preheater is provided with temperature feedback arrangement.
Energy-efficient double speed CFBB disclosed in this patent documentation, ventilated by air channel, a secondary air duct, although the soot particle that part is attached on air preheater can be blown away, but, but it being difficult to blow to the ash at these heat exchanger components of air preheater tube bank center, soot blowing is the most thorough, soot blowing effect is poor, affecting heat exchange efficiency, cause whole CFBB to be exerted oneself little, efficiency is low.
