Description
Przedmiotem wynalazku jest palnik do zgazowy¬ wania paliw w postaci pylu pod cisnieniem do 50X105 Pa przy uzyciu pylu z wegla brunatnego oraz srodka zgazowujacego albo mieszaniny srod¬ ków zgazowywujacych, które mozna doprowadzac z reaktora celem uzyskania gazu pod cisnieniem ze zgazowywania.Dotychczas w znanych urzadzeniach oddzielnego doprowadzania paliw w postaci pylu i srodka zga¬ zowujacego do przestrzeni zgazowywania, ogólnie zwanej palnikiem, prowadzi sie paliwo w postaci pylu przez centralnie umieszczony przewód w pal¬ niku.Wokól centralnego przewodu rozmieszczone sa z reguly koncentrycznie jedna lub kilka rur, tak ze tworza one pierscieniowe kanaly pomiedzy rurami.Kanaly te sluza do doprowadzania jednego luib kilku srodków zgazowywujacych albo miieszanin srodków zgaizowywujacych do przestrzeni reakcyjnej. Srodek zgazowywujacy albo srodki zgazowywujace wchodza do reakcja z tych kanalów ewentualnie o pierscie¬ niowym przekroju albo z otworów przewaznie za¬ mykajacych pierscieniowo rozmieszczone kanaly i reaguja nastepnie z centralnym strumieniem pylu.Doprowadzanie paliw w postaci pylu. np .pylu we¬ gla brunatnego do centralnie umieszczonej w pal¬ niku rury o przekroju kolowym jest rozwiazaniem prostym do urzeczywistnienia. Zgodnie z doswiad¬ czeniem mozna bez trudu transportowac fluidyzo- wany pyl wegla brunatnego przy uwzglednieniu 10 20 25 30 2 wlasciwych dla pylu warunków przy wzglednie wy¬ sokiej gestosci strumienia pylu w technicznie glad¬ kiej i prostej rurze o jednakowej powierzchni prze¬ kroju.W dotychczas realizowanych urzadzeniach prób¬ nych (np. B.US.Bureaiu of Mines Morgentown) jak równiez w propozycjach patentowych (nip. DOS nr 2536249, opis patentowy St. Zjedn. Ameryki nr 2702, 744, opis patentowy NRD nr 127904) stosuje sie za¬ sade centralnego prowadzenia substancji zgazowy- wanej w palniku.Istotna wada centralnego wyprowadzania sub¬ stancji zgazowywanej do przestrzeni reakcyjnej z koncentrycznie przebiegajacym doprowadzaniem srodka zgazowywujacego, przykladowo tlenu, tkwi w tym, ze przez koncentryczny, pierscieniowy stru¬ mien srodka zgazowywujacego na skutek recyrku¬ lacji, gaz z przestrzeni reakcyjnej moze mieszac sie ze srodkiem zgazowywujacym, jezeli nie oslania sde strumienia srodka zgazowywujacego przyklado¬ wo oslona pary przed gazem recyrkulacyjnym. Po¬ woduje to zuzycie czesci doprowadzonego tlenu do utleniania palnych gazów recyrkulacyjnych. Jednak korzystne jest przy cisnieniowym zgazowywaniu pylu doprowadzanie calkowitej ilosci substancji zgazowywujacej do reakcji z pylem i wykluczenie niepozadanych reakcji ubocznych tlenu ze wzgle¬ dów ekonomicznych przygotowywania tlenu.Dalsza wada doprowadzania calego zgazowywa- nego pylu weglowego do przestrzeni reakcyjnej ty\- 120 1795 120 179 6 wiaja palnik w przekroju poprzecznym odpowie¬ dnio wedlug linii A-A, B-B, C-C na fig 1.(Przez dwa doprowadzenia 2 o tej saimej charak¬ terystyce technicznej, miieszanina — gaz nosniko¬ wy — pyl weglowy dostaje sie z predkoscia 2—10 m/s do ukosnego odcinka krócca stycznego 6 obu- dowy palnika 3. Króciec styczny 6 stanowi powie- rzahniowo takie sarne przejscie z rury koloksztalt- nej w prostokatna szczeline konczaca sie w prze¬ strzeni pierscienioweij 5 palnika. Przestrzen pierscie¬ niowa posiada taka sama powierzchnie przekroju jak doprowadzenie mieszaniny gazu nosnikowego z pylem weglowym 2 i króciec styczny 6. Króciec styczny 6 jest nachylony do osi palnika pod ka¬ tem 45°.Przy wylocie palnika srodek zgazowywujacy z pierscienia zewnetrznego 4 i rury -centralnej 1 na skutek róznych kierunków doplywu i duzej pred¬ kosci rzedu 15—150 m/s powoduje rozproszenie mie¬ szaniny strumienia gaz nosnikowy — pyl weglowy, przy czym nastepuje intensywne zmieszanie pylu weglowego i srodka zgazowywujacego. Pierscienio¬ we doprowadzenie pylu zapewnia w pelni symetry¬ czne spalanie.

As a rule, one or more pipes are arranged concentrically around the central pipe so as to form These are ring-shaped channels between the pipes. These channels are used to feed one or more gasifying agents or mixtures of gasifying agents to the reaction space. The gasifying agent or the gasifying agents react from these channels, possibly with a ring cross-section, or from openings which usually close ring-shaped channels, and then react with the central stream of dust. The fuel supply is in the form of dust. for example, lignite dust to a centrally located circular pipe in the burner is a simple solution to implement. According to experience, it is possible to transport the fluidized lignite dust without difficulty, taking into account the dust-specific conditions with a relatively high dust jet in a technically smooth and straight pipe with a uniform cross-sectional area. The test devices implemented so far (e.g. B.US.Bureaiu of Mines Morgentown) as well as in patent proposals (e.g. DOS No. 2,536,249, U.S. Patent No. 2,702,744, GDR Patent No. 127,904) Principle of central discharge of the gasified substance in the burner. A significant disadvantage of the central discharge of the gasified substance to the reaction space with a concentric supply of the gasifying agent, for example oxygen, is that the concentric, ring-shaped stream of the gasifying agent is caused by the recycle ¬ lution, the gas from the reaction space may mix with the gasifying agent, as long as it does not cover the core of the gas stream. gasifying device, for example, a steam shield against the recirculation gas. This consumes some of the supplied oxygen to oxidize the flammable recirculation gases. However, it is advantageous in the pressure gasification of dust to bring the total amount of the gasifying substance to the reaction with the dust and to exclude undesirable side reactions of oxygen for economic reasons of oxygen preparation. A further disadvantage of feeding all the gasified coal dust to the reaction space of the back - 120 1795 120 179 6 It wraps the burner in a cross-section according to the lines AA, BB, CC in FIG. 1, respectively. (Through two inlets 2 of the same technical characteristics, the mixture - carrier gas - coal dust enters at a speed of 2-10 m / s to the oblique section of the tangential stub 6 of the burner housing 3. The tangential stub 6 is such a surface transition from a colloidal pipe to a rectangular slit ending in the burner annular space 5. The annular space has the same cross-sectional area. as for a mixture of carrier gas with coal dust 2 and tangential connector 6. Tangential connector 6 is inclined to the axis of the burner at an angle of 45 °. At the exit of the burner, the gasifying agent from the outer ring 4 and the central pipe 1, due to the different directions of inflow and the high velocity of 15-150 m / s, causes the mixture of the stream to dissipate. - coal dust, where the coal dust and the gasifying agent are mixed intensively. A ring-shaped dust supply ensures fully symmetrical combustion. It is also maintained in the absence of one stream of dust and allows the burner to be started with a different number of dust streams. Patent claim Burner for gasification of fuels in the form of dust, consisting of a central pipe, an outer ring for supplying gasification agents and supply elements dust and separating elements to supply the dust mixtures - carrier gas with a high load up to about 900 kg of dust / m3 of carrier gas in a reactor pressurized up to 50 × 106 Pa, characterized by the circular cross-section series being the lead (2) of the mixture of coal dust - carrier gas passes into the annular space (5) situated concentrically around the central pipe (1) for the gasifying agent, while the feed (2) of the mixture of carrier gas - coal dust and concentric rings the spaces (5) have the same surface, and the circularly shaped inlets (2) of the carrier gas-coal dust mixture are maintained at all times and in the unchanged cross-sectional plane, it passes in front of the burner housing (3) into a rectangular slot with an outlet opening tangent to the corresponding annular space (5). 10 15 20 120 179 ZGK 0543 / 110-0 / 83 - 110 copies Price PLN 100, - PL
