Abstract

Przedmiotem zgłoszenia jest palnik do kotła na paliwo granulowane, szczególnie pellet drzewny, także pellet ze słomy, łuski słonecznika, pestki z owoców pestkowych. Niecka (1) komory spalania ma dno w postaci pobocznicy (2) obrotowego walca o osi obrotu (6) równoległej do krawędzi dna niecki (1). Minimalna średnica walca (2) jest równa szerokości niecki (1) komory spalania, z kolei jego wysokość jest przynajmniej równa długości dna niecki (1) komory spalania. W pobocznicy walca (2) są otwory (7) na powietrze, przez które jest doprowadzane do komory spalania. W pobocznicy walca (2) jest szczelina (3) o szerokości równej maksymalnie szerokości dna niecki (1) komory spalania. Szczelina jest tak uformowana, że stanowi wycinek walca (2) ze szczelnymi ścianami bocznymi (4) i z dnem (5) w pobliżu osi obrotu (6) walca (2). W trakcie spalania pelletu nasypanego do niecki (1) komory spalania walec (2) jest tak ustawiony, że jego pobocznica stanowi dno niecki (1). Powstały popiół zbiera się na dnie niecki (1) komory spalania, wtedy uruchamia się obrót walca (2). Powoduje to wzruszenie zgromadzonego przy dnie popiołu, zeskrobywanie go przez krawędź niecki (1) z pobocznicy walca (2) i następuje stopniowe jego wpadanie do szczeliny (3) w pobocznicy walca (2). Gdy szczelina (3) jest już u dołu popiół grawitacyjnie wysypuje się z niej do popielnika i stamtąd jest usuwany ręcznie lub mechanicznie. W tym czasie na pobocznicę walca (2), która teraz stanowi dno niecki (1) komory spalania, wsypywana jest kolejna porcja pelletu, następuje zapłon i spalanie paliwa i cykl się powtarza.The subject of the application is a burner for a boiler using granulated fuel, particularly wood pellets, including straw pellets, sunflower husks, and stone fruit seeds. The combustion chamber basin (1) has a bottom in the form of a sidewall (2) of a rotating cylinder with an axis of rotation (6) parallel to the edge of the bottom of the basin (1). The minimum diameter of the cylinder (2) is equal to the width of the combustion chamber basin (1), and its height is at least equal to the length of the bottom of the combustion chamber basin (1). The sidewall of the cylinder (2) has openings (7) for air through which it is supplied to the combustion chamber. The sidewall of the cylinder (2) has a slot (3) with a maximum width equal to the width of the bottom of the combustion chamber basin (1). The slot is shaped so that it constitutes a section of the cylinder (2) with tight side walls (4) and a bottom (5) near the axis of rotation (6) of the cylinder (2). During combustion of pellets poured into the combustion chamber's basin (1), the cylinder (2) is positioned so that its sidewall forms the bottom of the combustion chamber's basin (1). The resulting ash collects at the bottom of the combustion chamber's basin (1), which then initiates the cylinder's rotation. This causes the ash accumulated at the bottom to be agitated, scraped off the cylinder's sidewall (2) by the edge of the basin (1), and gradually falls into the slot (3) in the cylinder's sidewall (2). When the slot (3) is at the bottom, the ash flows out by gravity into the ash pan and is removed manually or mechanically. Meanwhile, another portion of pellets is poured onto the cylinder's sidewall (2), which now forms the bottom of the combustion chamber's basin (1), ignites and burns the fuel, and the cycle repeats.
