Abstract

Sposób zasilania kotła rusztowego z wielopaliwowymi palnikami polega na tym, że paliwa alternatywne w postaci ciekłej gazowej, pyłowej lub zawiesiny rozdrobnionego paliwa spala się w co najmniej jednym palniku wielopaliwowym (2) w komorze paleniskowej (3) kotła rusztowego (1) a strumień spalin wypływa z wielopaliwowych palników (2) w kierunku rusztu (4) w komorze paleniskowej (3) a recyrkulacja spalin następuje w objętości komory paleniskowej (3). Instalacja zasilania kotła rusztowego z wielopaliwowymi palnikami, w przedstawionym na rysunku, palenisku kotła ciepłowniczego, składającym się z rusztu (4) umieszczonego w dolnej części otoczonej rurami ekranowymi (5) komory paleniskowej (3), ma wielopaliwowe palniki (2) zainstalowane w odgięciach rur ekranowych (5) komory paleniskowej (3) w górnej części kotła rusztowego (1) a osie główne wielopaliwowych palników (2) skierowane są na ruszt kotła (4), przy czym wielopaliwowe palniki (2) wyposażone są w króćce doprowadzające powietrze do spalania (6), paliwo gazowe lub pyłowe (7) oraz króciec doprowadzający paliwo ciekłe lub ciekłą zawiesinę rozdrobnionego paliwa stałego (8) i króciec czynnika dyspergującego paliwa ciekłe (9).The method of feeding a grate boiler with multi-fuel burners is based on the fact that alternative fuels in the form of liquid gas, dust or a suspension of fragmented fuel are burned in at least one multi-fuel burner (2) in the furnace chamber (3) of the grate boiler (1) and the flue gas flows out from multi-fuel burners (2) towards the grate (4) in the combustion chamber (3), and exhaust gas recirculation takes place in the volume of the combustion chamber (3). The grate boiler power supply system with multi-fuel burners, in the furnace of the district heating boiler shown in the figure, consisting of a grate (4) placed in the lower part surrounded by screen tubes (5), the furnace chamber (3) has multi-fuel burners (2) installed in the bends of the pipes screen (5) of the furnace chamber (3) in the upper part of the grate boiler (1), and the main axes of multi-fuel burners (2) are directed to the boiler grate (4), while multi-fuel burners (2) are equipped with combustion air connections ( 6), gaseous or pulverized fuel (7) as well as a connection for supplying liquid fuel or a liquid suspension of ground solid fuel (8) and a connection for liquid fuel dispersant (9).
