2、設(shè)備，供熱能力為14.18106kJ/h304.18106kJ/h。熱風(fēng)爐主要由燃料供應(yīng)裝置、供風(fēng)裝置、燃燒裝置、燃燒室、混合室及熱工控制系統(tǒng)組成。本產(chǎn)品結(jié)構(gòu)簡單、體積小巧、操作安全、維護(hù)簡便、使用壽命長、供熱范圍廣，溫度可隨意調(diào)配，廣泛應(yīng)用于水泥、化工、冶金等行業(yè)中的烘干、焙燒設(shè)備提供熱源。二、工作原理燃油熱風(fēng)爐工作原理：燃料由供應(yīng)裝置安全輸送到燃燒器，與供風(fēng)裝置送入的空氣經(jīng)燃燒器組織在燃燒室里充分燃燒，產(chǎn)生的高溫氣體在混合室內(nèi)與冷空氣混合得到符合工藝要求的熱煙氣。三、規(guī)格與技術(shù)參數(shù) 產(chǎn)品型號(hào)YR-nD（Z、G） n=130，n=1表示14.18106kJ/h供熱能力G表示高溫型，供熱溫度為

3、6001200Z表示中溫型，供熱溫度為300600D表示低溫型，供熱溫度為100300燃油熱風(fēng)爐四、安裝調(diào)試與操作使用規(guī)程安裝爐體安裝：爐子要安裝在牢固的基礎(chǔ)上,各連接法蘭之間應(yīng)加石棉繩密封,詳見燃油熱風(fēng)爐安裝圖。燃燒機(jī)安裝：1、燃燒機(jī)的噴火口應(yīng)插入爐膛火口之內(nèi),其深度視爐墻厚度而定,不宜大于150毫米。爐墻火口內(nèi)徑比燃燒機(jī)前端外筒大于15毫米，火口呈4550錐角，這樣可避免燒重油時(shí)，在火口錐面上結(jié)焦。2、插入深度及傾斜角度等定妥后，把燃燒機(jī)外面的活動(dòng)法蘭焊在外筒上。如爐膛有正壓，則在法蘭與爐墻板之間加墊石棉板，以免爐內(nèi)火焰外冒。這樣可防止燒毀機(jī)殼，且節(jié)約能源，爐內(nèi)正壓如大于10毫米水柱以上，

4、用戶應(yīng)在爐尾加引風(fēng)機(jī)抽爐尾氣排出、或加高抽風(fēng)煙囪。3、燃燒機(jī)用36個(gè)壓板螺釘將焊連在燃燒機(jī)前端外筒上的法蘭或用壓板固定在爐墻板面上,或用支撐架固定即可。4、打開風(fēng)機(jī)電機(jī)上的電線蓋板，接通輸入電源 ，檢查電機(jī)方向是否正確。5、安裝輸油泵時(shí)，應(yīng)檢查電機(jī)方向是否與銘牌方向一致。油管路上應(yīng)有過濾裝置，還應(yīng)有回油系統(tǒng)，靠燃燒機(jī)前應(yīng)有油管接頭及壓力表，表之外應(yīng)安裝有可調(diào)節(jié)針型閥，再用軟管連接。6、燒重油用戶，輸入油路應(yīng)有蒸汽保溫與蒸汽掃管線的裝置。點(diǎn)火前應(yīng)有蒸汽掃線與預(yù)熱油路、噴油嘴等。重油到爐前的油溫不低于120130，否則霧化不好，在火焰筒內(nèi)易產(chǎn)生結(jié)焦。操作使用首次點(diǎn)火前的檢查工作：檢查燃燒機(jī)及其配套

5、件安裝情況，檢查油路、電路、風(fēng)路是否安全暢通。接通電源，手動(dòng)檢查風(fēng)機(jī)及油泵運(yùn)轉(zhuǎn)方向是否正確。若是反轉(zhuǎn)了、則應(yīng)斷開電源開關(guān)，將反轉(zhuǎn)的油泵、風(fēng)機(jī)接線任意換1相即可改變轉(zhuǎn)動(dòng)方向。檢查油路、風(fēng)路電磁閥和調(diào)節(jié)閥是否動(dòng)作，再將輸油軟管從噴油嘴上扭下，打開油閥，放油一刻鐘到桶中，目的是清除輸油管路中的雜質(zhì)。觀察后如無異常情況，可進(jìn)入手動(dòng)點(diǎn)火調(diào)試工作，手動(dòng)點(diǎn)火調(diào)試工作正常后，方可進(jìn)行自動(dòng)或中控操作。每次點(diǎn)火前的準(zhǔn)備工作：清除爐膛中的積渣、雜物，打開風(fēng)機(jī)吹掃爐膛35分鐘。若燃用重油，應(yīng)先打開加熱重油的蒸氣閥門約三分鐘，待管中積水放完，開始冒汽時(shí)關(guān)閥，再打開掃線汽閥及噴油嘴上手輪閥，使蒸氣沿未被保溫的油路及噴油嘴

6、噴入燃燒機(jī)及爐膛中，將油路及油嘴等預(yù)熱，約10分鐘待油嘴體表面燙手后，可關(guān)蒸氣。2.調(diào)試打開煙道龍門閥，關(guān)閉風(fēng)機(jī)風(fēng)門，啟動(dòng)風(fēng)機(jī)，此時(shí)爐膛應(yīng)有負(fù)壓，打開風(fēng)門吹掃爐膛后再關(guān)閉風(fēng)門。調(diào)整回油管道上的調(diào)節(jié)閥，啟動(dòng)油泵，使其油壓上升到1.0MPa，點(diǎn)火后發(fā)現(xiàn)燃燒冒煙，可能是油壓調(diào)得過高，手動(dòng)將回油閥門調(diào)大，觀察火焰狀況，直到不冒煙為止。爐溫或料溫不夠，可能是供油壓過低，將回油調(diào)節(jié)閥慢慢關(guān)小，油壓升高，火量增大，同時(shí)手動(dòng)調(diào)整風(fēng)門，直到燃燒穩(wěn)定達(dá)到所需要溫度為止。如仍達(dá)不到溫度要求，則檢查其它原因或檢查是否屬選型過小，應(yīng)換大一型號(hào)燃燒機(jī)。 3.正常安全操作規(guī)程檢查機(jī)、電設(shè)備是否正常，油、氣管路是否通暢，清除

7、噴嘴口的積油或焦塊。點(diǎn)火前要打開管道調(diào)節(jié)閥，啟動(dòng)鼓風(fēng)機(jī)時(shí)，風(fēng)閥要關(guān)嚴(yán)密，待正常運(yùn)行后，打開風(fēng)閥吹掃爐膛3-5分鐘，然后關(guān)掉調(diào)風(fēng)閥點(diǎn)火時(shí)，要使?fàn)t內(nèi)處于負(fù)壓狀態(tài)，壓力保持在-100-150Pa；如負(fù)壓大影響點(diǎn)火時(shí)，可調(diào)整管路閥門，同時(shí)保證爐膛處于微負(fù)壓狀態(tài)。一般情況下，爐內(nèi)溫度控制在800，根據(jù)需要通過管路調(diào)節(jié)閥及爐膛擋火板微調(diào)煙氣溫度使之符合工藝要求(一般在100300，依據(jù)對象不同而定)。根據(jù)尾氣溫度需要，調(diào)整油壓，根據(jù)燃燒火焰狀況調(diào)整風(fēng)閥。在同一油壓下,通過調(diào)節(jié)風(fēng)閥,保證燃油充分燃燒,火焰不宜過長。如要加溫，先加大油壓，同時(shí)要加大風(fēng)門。減壓就相應(yīng)減風(fēng)。如系冷爐，則不能升溫過快，開小火逐步升溫

8、10分鐘左右再開大火。停爐時(shí)，先關(guān)燒嘴進(jìn)油電磁閘閥，再關(guān)油泵。3分鐘后停止供風(fēng)風(fēng)機(jī)，關(guān)閉管道調(diào)節(jié)閥。自動(dòng)操作時(shí)，系統(tǒng)啟動(dòng)后按照程序自動(dòng)運(yùn)行，根據(jù)尾氣溫度變化對調(diào)節(jié)閥進(jìn)行自動(dòng)調(diào)節(jié)使系統(tǒng)達(dá)到供熱平衡。3.注意事項(xiàng)：如點(diǎn)火未著，則迅速關(guān)閉油閥，開大風(fēng)量吹掃爐膛，3分鐘后再按程序點(diǎn)火，以防爐膛內(nèi)油霧積累過多汽化再次點(diǎn)火時(shí)引起爆炸。點(diǎn)火時(shí)，操作人員必須站在點(diǎn)火孔側(cè)邊，注意回火引起事故。如出現(xiàn)火焰易脫火，燃燒不穩(wěn)的情況，應(yīng)調(diào)小風(fēng)閥，將火焰燒到燃燒器里面，再適當(dāng)調(diào)大即可。如出現(xiàn)燃燒火焰過短，或火焰明顯變形，就可能是油槍出現(xiàn)堵塞而異致霧化不良燃燒不好，處理方法是將油槍前端油咀部分折開清洗霧化片和旋流套，然后按

9、順序裝配即可（注意要擰緊）。油泵的使用壓力在0.51.5MPa之間，可根據(jù)爐溫所需而調(diào)整,但不允許將爐膛燒紅導(dǎo)致爐體變形。五、維護(hù)保養(yǎng)與常見故障的排除維護(hù)保養(yǎng)過濾網(wǎng)應(yīng)及時(shí)拆洗，清除雜質(zhì)、修補(bǔ)濾網(wǎng)損處?；鹧嫱矐?yīng)定期清掃，保持筒壁面的干凈與氣道的暢通。特別當(dāng)油質(zhì)差、油溫低，空氣不干凈時(shí)更應(yīng)勤于清掃。油槍應(yīng)定時(shí)拆洗，保持流道的暢通。拆卸油槍應(yīng)按程序與規(guī)定進(jìn)行，不能損壞。經(jīng)常檢查油溫、油壓、風(fēng)壓儀表的準(zhǔn)確性。經(jīng)常檢查各種閥門的密封性?；鹂诖u錐面上不能有雜物堆積，應(yīng)及時(shí)清掃，否則會(huì)引起回火，燒壞燃燒器。經(jīng)常檢查風(fēng)路、油路的密封性。工作時(shí)應(yīng)保持蒸汽能在重油油路的保溫套管中流動(dòng)。噴油嘴中霧化片零件如發(fā)現(xiàn)有磨

10、損，應(yīng)及時(shí)更換，否則影響霧化效果。火焰筒如有損壞應(yīng)及時(shí)修復(fù)，否則因損壞而改變空氣流通面積，影響燃燒效果。常見故障的排除(見表)六、安全事項(xiàng)1、點(diǎn)火時(shí)，工作人員不得站在爐前，以免爆燃噴火傷人。2、火焰熄滅或一次點(diǎn)火不成功，應(yīng)立即停止點(diǎn)火，關(guān)閉供油閥和空氣閥，排除爐內(nèi)未燃燼的油氣后再重新點(diǎn)火；燃用重油時(shí)，還需接通蒸汽清掃供油管路，排除未燃燼的油氣后再重新點(diǎn)火。.

16、ot-blast stove installation picture.Combustion machine installation:a. Spray blow hole of the combustion machine is put in the blow hole of stove chamber, the depth decided by the thickness of the boiler setting, favorably not deeper than 150 mm. The internal diameter of the blow hole of boiler sett

17、ing is 15mm longer than that of front can of combustion machine. The blow hole of boiler setting is designed at a cone angle of 4550.so that no knot coke is produced on the awl surface when heavy oil is combusted.b. After the depth and the cone angle is decided, weld flexible flange outside the comb

18、ustion machine on the outside can. If the pressure in the stove chamber is positive, put asbestos board between flange and boiler setting board in order to prevent of the flame inside. In this way, the machine coating will not be burned out and energy can be saved. If the positive pressure is strong

19、er than 10 mm water column, users should use draw fan to exhaust stove vent gas or add chimney of exhausting gas.c. Fix the flange that is welded on the front outside can of the combustion machine on the board surface of the boiler setting with 36 pressing plate screws or fix it with tie-in or with

20、carriage d. Open the wire cover board of the blower fan engine, plug it in and check the direction of the engine.e. When installing the oil pump, examine whether the engines direction is in accordance with that of the nameplate. There should be a filtering equipment on the oil pipe and a return oil

21、system. In front of the combustion machine should be an oil pipe joint and pressure meter, beside which adaptable needle valve must be installed and connected with soft pipes.f. For heavy oil users, on the oil input route should be steam heat preservation and steam scavenging pipeline. Before igniti

22、on there should be steam scavenging line and warming-up oilway and carburetor jet. The temperature of heavy oil should be no less than 120-130 before it comes to the stove. Otherwise, atomization is not complete and it is easy to agglomerate inside the flame can.2. Operationa. Check-up before the fi

23、rst lightingCheck the installation of combustion machine and its accessories; make sure that oil path, circuit and air road are correctly connected. Switch on and manually examine the operation direction of wind machine and oil rump. If they are going otherwise, switch off immediately and change eit

24、her phase of the oil pump or wind machine so that the operation direction will change. Examine the oil path, wind path solenoid valve and adaptation valve to ensure they are working; screw the soft oil tube off carburetor jet, open the oil valve and put oil in the barrel for 15 minutes in order to c

25、lear away the impure things in the pipe.Preparations before each lighting:Al. clear away the product drugs and miscellaneous things; air the sweep chest stove with fan for 35 minutes.A2. Open the steam valve for warming up heavy oil about 3 minutes until completely emitting the product water. Shut t

26、he valve when steam comes out, and open sweep line steam valve and atomizer start ship valve so that steam spray into combustion machine and stove chamber along injection valve and oil path that is not kept warm. Preheat oil path and glib for about 10 minutes until the surface is hot and shut off st

27、eam.b. AdaptationOpen the flue valve and close the gate of wind machine, start the machine. Then there is negative pressure inside the stove; open the wind gate, sweep the stove chamber and close the gate again. Tune the adaptation valve on the oil pipe path, start the oil pump and increase the oil

28、pressure to 1.0Mpa. When smoke accompanies combustion after ignition, it may be concluded that the oil pressure is higher. Manually open the return oil valve wider and observe the flame until no smoke comes out. If the temperature of the stove or materials is not sufficiently high, it may be due to

29、low oil pressure; then turn down the oil adaptation valve to increase the oil pressure and strengthen the fire. Meanwhile, manually adapt the wind gate until required temperature is reached for stable combustion. If required temperature cannot be reached yet, then examine whether the machine is too

30、small and have a larger combustion machine.c. Safe operation instructionsC1. Examine whether machines and power equipment are in good condition and whether oil and air paths are clear; clear away product oil and knot coke at injection valve. C2. Open the tube adaptation valve before ignition; shut t

31、he wind valve when starting the fan. Air sweep stove chamber for 35minutes after it operates properly and then close the wind valve.C3. Keep stove chamber at low pressure of-100150Pa when lighting fire; if negative pressure is too high and affects lighting fire, adapt pipeline valve and ensure stove

32、 chamber at low negative pressure.C4. Generally, stove chamber temperature should be under 800；the air temperature can be adapted by pipeline valve and stove chamber gear fiery board to suit the requirements of craftsmanship (ordinarily 100300,according to different objects)C5. Adapt oil pressure ac

33、cording to the need of stove temperature; adapt air valve in accordance with the condition of flame. Under the same oil pressure, make sure fuel burns fully by adapting air valve. Flame should not be too long. If temperature needs to be raised, increase oil pressure first and open the air valve wide

34、r at the same time. Decreasing pressure will decrease air valve accordingly.C6. Temperature should not be increased too abruptly in cold stove. Weak fire for 10 minutes, then strong fire.C7.When stopping combustion, turn off burner input oil floodgate valve, and then shut oil pump. Turn off air prov

35、ider 3 minutes later and close the tube adaptation valve.C8. Have the machine operating automatically in accordance with the prescribed procedure after it is started in the case of manual operation. Adapt the adaptation valve automatically according to the changes of temperature of tail gas so as to

36、 achieve heat supply balance of the system.d. AttentionD1. If lighting is not successful, shut oil valve immediately; increase air to blow sweep stove chamber; light fire 3 minutes later according to procedure to avoid explosion caused steam out of oil fog in stove chamber at the second fire-lightin

37、g.D2. Operator should not stand right in front of fire-lighting hole when lighting fire in order to avoid any danger caused by return fire.D3. If flame is stable or combustion is unsteady, turn down air valve so that flame keeps burning in combustion chamber, and then turn up air valve.D4. If flame

38、is too short or obviously in unusually shape, it is possibly because oil gun is jammed, which leads to atomization and bad combustion. Take apart the front glib of oil gun and clean atomization plate and spiral flow cover, and then assemble then as they are (please screw tight).D5. Pressure in use o
