Description
Technical field
The utility model belongs to the heating furnace technology, is specifically related to a kind of solid fuel heat carrier furnace.
Background technology
Heat carrier furnace is to heat carrier (or claiming heat-conducting medium) such as liquid thermal conductivity oil, solid sylvite and the gas chain phenylate heating back supply heating furnace with hot equipment work.Prior art roughly can be divided solid fuel (as coal, wood waste) heat carrier furnace, liquid fuel (as fuel oil) heat carrier furnace and gaseous fuel (as coal gas, natural gas, oil gas) heat carrier furnace by fuel mode.Because be that technological requirement by target is determined with the operating temperature of hot equipment, thereby the temperature of the heat-conducting medium of heat carrier furnace, must satisfy and use hot process requirement of equipment.For this reason, heat carrier furnace should possess the ability of regulation and control heat carrier temperature.The means of prior art regulation and control heat carrier temperature for liquids and gases fuel heat bearer boiler, realize by adjusting fuel feeding, air demand; And for the solid fuel heat carrier furnace, generally realize by replenishing the normal temperature heat-conducting medium.For example, the solid fuel heat-conducting oil furnace, be by with heat-conducting oil heating to more than the required operating temperature, replenish in overheated conduction oil then that the normal temperature conduction oil realizes.This is because the temperature of the flue gas that solid fuel such as fired coal combustion generate is mainly determined by solid fuel quantity delivered and wind supply quantity.The height of the flue-gas temperature that burning generates can be regulated by the increase and decrease of solid fuel quantity delivered and wind supply quantity.But this depending on changes the solid fuel ignition state produces slow influence to the heat-conducting medium temperature adjusting, but because fired coal combustion will have a process to realize, thereby the hysteresis that causes gradient of temperature to regulate, therefore, the temperature control precision of prior art solid fuel heat carrier furnace is all poor, generally all 〉=± 3 ℃.And along with the development of modern manufacturing industry, industrial heat equipment such as chemical industry, medicine, textile printing and dyeing and light industry leather paper industry use hot equipment, require strictly day by day for the temperature control precision of heat carrier, the temperature error scope is very little.For example washing and compiling manufacturing technique requirent heat carrier temperature is 330 ℃ ± 1 ℃.Certainly, this specification requirement is satisfiable for liquid or gaseous fuel heat carrier furnace.But to existing solid fuel heat carrier furnace is impossible.This is because 330 ℃ of the temperature of desired heat carrier, and near the coking temperature of conduction oil, if take more than the heat-conducting oil heating to 330 ℃, and then additional normal temperature conduction oil carries out adjustment, and this is still not unpractical, is irrealizable yet.Therefore adopt relatively inexpensive coal-fired and can regulate and control the research and development of the solid fuel heat carrier furnace of heat carrier temperature, the problem that had become the insider already and paid close attention to.
Summary of the invention
The purpose of this utility model is to provide a kind of solid fuel heat carrier furnace that can be used for accuracy controlling heat carrier temperature behind equipped flue gas flow adjuster, to satisfy the demand of the industrial production technology that makes rapid progress.
In realizing the technical scheme R﹠D process of the purpose of this utility model, the repetition test that combines by theory and practice, and the particular content relevant to the technical solution of the utility model obtained following cognition:
The flue total release of heat carrier furnace, the total amount of the flue gas that must generate greater than fuel combustion.That is to say the solid fuel ignition chamber and the whole exhaust gases passes of heat carrier furnace, all under negative pressure, work.And equipressure or overvoltage all can cause the leakage of flue gas, make the heat carrier furnace scaling loss, shorten its service life.This is breakneck.About this problem, in manufacturing and designing in the process of existing heat carrier furnace, to be grasped by people, the utility model must be accomplished to work under negative pressure equally.
The temperature increase of the heat-conducting medium of heat carrier furnace is that the heat radiation and the heat exchange of the flue gas that generates by the fuel combustion of accepting heat carrier furnace realizes.The utility model is by the discharging approach of the flue gas of change fuel combustion generation, as at the radiant section exhaust gases passes of heat carrier furnace or at certain position of convection section exhaust gases passes, add the gas bypass floss hole, and take supplementary measures to regulate and control the flow direction and the flow of flue gas, can reach and reduce or increase thermal conduction effect, and reduce or improve the heat-conducting medium temperature, realize the purpose of regulation and control heat-conducting medium temperature.
The heating surface of heat carrier furnace is made up of radiant section heating surface and convection section heating surface.And the exhanst gas outlet position of heating surface spontaneous combustion chamber is initial, is preface with convection section heating surface behind the first radiant section heating surface, is separately positioned in radiant section exhaust gases passes and the convection section exhaust gases passes; And exhaust gases passes terminal floss hole is set in the terminal of convection section exhaust gases passes.In order to make full use of the heat of solid fuel ignition, reduce solid-fuelled consumption, the convection section of heat carrier furnace (comprising convection section dividing wall type heating surface and convection section exhaust gases passes corresponding with it) should have enough length.This is that people are known.But heat carrier furnace can not manufacture tunnel heating.Because of the prior art of dividing plate or partition wall is set at convection section, just realized prolonging the purpose of convection section.Plan of establishment the utility model of this convection section can be adopted equally, and more helps enforcement of the present utility model and effect.
The result of the test prompting, do not changing solid-fuelled fired state in the combustion chamber, regulate the flue gas flow of exhaust gases passes terminal floss hole and gas bypass floss hole respectively by measure, can avoid of the influence of fuel combustion situation, and obtain the heat-conducting medium accuracy control over temperature to the heat-conducting medium gradient of temperature.In other words, gas bypass floss hole discharge capacity is transferred big, and the heat-conducting medium temperature just reduces; Otherwise gas bypass floss hole discharge capacity has been turned down or has not been discharged, and then the heat-conducting medium temperature just promotes.
By above repetition test demonstration, the utility model is realized the technical scheme of its purpose, even if clearly displayed.
The utility model realizes that the technical scheme of its purpose is, a kind of solid fuel heat carrier furnace, has the solid fuel ignition chamber, the whole dividing wall type heating surface that connects to form by radiant section dividing wall type heating surface and convection section dividing wall type heating surface, the whole exhaust gases passes that connects to form by radiant section exhaust gases passes and convection section exhaust gases passes, and be located at the exhaust gases passes terminal floss hole of convection section exhaust gases passes terminal, its improvement is: exhaust gases passes also has at least 1 gas bypass floss hole, and said gas bypass floss hole directly communicates with whole exhaust gases passes.
Promptly provide a kind of solid fuel heat carrier furnace that behind equipped flue gas flow adjuster, can be used for accuracy controlling heat carrier temperature by such scheme.When the user at exhaust gases passes terminal floss hole of the present utility model and gas bypass floss hole, the flue gas flow adjuster directly is installed respectively, (this is that the user makes installation voluntarily because of many flue gas flow adjusters perhaps after the continuation installation further channel flue gas flow adjuster to be installed again, certainly also can require random installation), then by of the adjusting of said adjuster to the fume emission flow of exhaust gases passes terminal floss hole and gas bypass floss hole, just can no longer rely on and change of the slow influence of solid fuel ignition state the heat-conducting medium temperature, and obtain accuracy controlling, thereby realized the purpose of this utility model to the heat-conducting medium temperature.
Further improvement of the utility model point also is:
At exhaust gases passes terminal floss hole place and gas bypass floss hole place, be equipped with the fume emission flow regulator.Obviously, its purpose is to use convenience of the present utility model for the user further provides.That is to say that the user need not oneself be equipped with the fume emission flow regulator again, and can adopt the flue gas flow adjuster of random installation directly to use the utility model.
Said fume emission flow regulator can adopt gate valve type fume emission flow regulator, perhaps turnover plate type fume emission flow regulator, perhaps ball-valve type fume emission flow regulator.The utility model is turnover plate type fume emission flow regulator preferably.This is that the working condition of turnover plate type fume emission flow regulator is relatively good because under the working environment of higher temperature and higher dust content.
Said gas bypass floss hole directly communicates with the radiant section exhaust gases passes terminal region of exhaust gases passes, or directly communicates with the initiating terminal position of the convection section exhaust gases passes of exhaust gases passes.Its purpose obviously is in order to realize that heat-conducting medium heat carries the regulation and control of temperature in scope by a relatively large margin.This is to open or partially open through the bypass discharge leg mouth because work as the flue gas at said position, make the flow direction of flue gas form " short circuit ", convection section dividing wall type heating surface is just no longer accepted heating or is accepted heating less, and the heat of heat-conducting medium is carried temperature and also just is able to obviously descend fast.Otherwise the heat of heat-conducting medium is carried temperature and is also just obviously risen fast.
The radiant section exhaust gases passes of said gas bypass floss hole and exhaust gases passes and convection section exhaust gases passes connect hands over the position directly to communicate.Its purpose obviously with the gas bypass floss hole is located at radiant section exhaust gases passes terminal region or is located at the purpose at convection section exhaust gases passes initiating terminal position identical.
Said gas bypass floss hole communicates with convection section exhaust gases passes initiating terminal to the position between the exhaust gases passes terminal floss hole of exhaust gases passes.Its purpose obviously is in order to realize year control of temperature in less amplitude range of heat-conducting medium heat.This is because with flowing to of flue gas formed " short circuit " point, change position by the initiating terminal position of convection section exhaust gases passes near its terminal to the convection section exhaust gases passes, thereby make convection section dividing wall type heating surface have at least part to accept heating, the heat of heat-conducting medium is carried the slow decline that temperature also just is able to less amplitude.Otherwise the heat of heat-conducting medium is carried temperature also just with more by a small margin slow rising.
Certainly, said gas bypass floss hole also can make it connect with the convection section exhaust gases passes and hand over position and convection section exhaust gases passes initiating terminal to four positions such as position between the exhaust gases passes terminal floss hole to communicate simultaneously with terminal region, the initiating terminal position of convection section exhaust gases passes, the radiant section exhaust gases passes of radiant section exhaust gases passes.Do like this, to the regulation and control of heat-conducting medium heat year temperature, will be more flexible and more accurate.
After the technical solution of the utility model was implemented, the characteristics that the heat-conducting medium temperature that it had derives the solid fuel heat carrier furnace can accurately be controlled were conspicuous, and have simple in structure, advantage such as preparation cost is low, and is easy to operate.
