Description
Przedmiotem wynalazku jest sposób podawania paliwa w kotle centralnego ogrzewania z palnikiem automatycznym zasilanym paliwem stałym.The subject of the invention is a method of feeding fuel in a central heating boiler with an automatic burner powered by solid fuel.
W znanych dotychczas rozwiązaniach dotyczących kotłów automatycznych na paliwo stałe, podawanie paliwa i jego spalanie odbywa się jako proces ciągły.In the previously known solutions for automatic solid fuel boilers, fuel feeding and its combustion are carried out as a continuous process.
Podajnik paliwa pracuje w regularnych, powtarzalnych cyklach pracy i postoju. Zmiana mocy kotła odbywa się wyłącznie przez zmianę proporcji czasu pracy i czasu postoju podajnika paliwa.The fuel feeder works in regular, repetitive work and standstill cycles. The boiler power is changed only by changing the proportion of the operation time and the idle time of the fuel feeder.
Wadą procesu ciągłego podawania paliwa jest problem z dobieraniem proporcji paliwa i powietrza ze względu na przypadkowość i losowość procesu spalania. Kolejne porcje paliwa podawane są w tak niewielkiej odległości czasowej od siebie, że nie można ocenić czy poprzednia dawka paliwa uległa dopaleniu. Znaczące wydłużanie czasu postoju podajnika zawsze musi się wiązać ze znaczącym wydłużeniem czasu podawania dawki paliwa, co powoduje jego stratę poprzez proces niezupełnego spalania.The disadvantage of the continuous fuel feeding process is the problem with selecting the proportions of fuel and air due to the randomness and randomness of the combustion process. The consecutive portions of fuel are delivered at such a short distance from each other that it is impossible to assess whether the previous fuel dose has burned out. Significant extension of the feeder standstill time must always be associated with a significant extension of the time of feeding the fuel dose, which causes its loss due to the process of incomplete combustion.
W sposobie według wynalazku podawanie podajnikiem paliwa spalanego w strumieniu powietrza następuje w sposób grupowy (impulsowy). Po kilku lub kilkunastu cyklach pracy i krótkich postojów podajnika następuje przerwa w dawkowaniu paliwa, przynajmniej kilkukrotnie dłuższa w stosunku do poprzednich postojów podajnika. Pozwala ona na dopalenie dostarczonego wcześniej paliwa i umożliwia określenie momentu podania następnej porcji paliwa.In the method according to the invention, the fuel burnt in the air stream is fed in a group (pulse) manner with the feeder. After several or a dozen or so work cycles and short feeder stops, there is a break in fuel dosing, at least several times longer than in the previous feeder stops. It allows you to burn off the previously supplied fuel and allows you to determine the moment of feeding the next portion of fuel.
Sposób według wynalazku usuwa mankamenty dotychczasowych rozwiązań podawania paliwa w kotłach automatycznych na paliwo stałe. Zapewnia optymalizację procesu spalania paliw stałych w kotle centralnego ogrzewania, gdyż umożliwia za pomocą znanych metod (analizatora spalin, sondy lambda, analizy trendów temperatury spalin) na precyzyjne określenie momentu podania następnej porcji paliwa. Pozwala również na spalanie tzw. trudnych węgli, na przykład koksujących czy spiekających się.The method according to the invention removes the shortcomings of the previous solutions of fuel feeding in automatic solid fuel boilers. It ensures optimization of the combustion process of solid fuels in the central heating boiler, as it enables the use of known methods (exhaust gas analyzer, lambda probe, analysis of exhaust gas temperature trends) to precisely determine the moment of feeding the next portion of fuel. It also allows you to burn the so-called difficult coals, for example coking or sintering.
Zasady sposobu podawania paliwa w kotle centralnego ogrzewania z palnikiem automatycznym uwidocznione są na rysunku, na którym Fig. 1 - przedstawia zasadę dotychczas stosowanych rozwiązań, zaś Fig. 2 - zasadę dawkowania paliwa według wynalazku.The principles of the fuel feeding method in a central heating boiler with an automatic burner are shown in the drawing, in which Fig. 1 - shows the principle of the solutions used so far, and Fig. 2 - the principle of fuel dosage according to the invention.
