Abstract: A locomotive (10) for spreading a waterproof coil in a hot melt manner. The locomotive (10) for spreading a waterproof coil in a hot melt manner comprises: a locomotive frame (11), provided with a coil support (12); and wheel devices, a spreading device, a combustion and heating device and a coil compaction device that are disposed on the locomotive frame (11). The combustion and heating device comprises a combustion chamber (6) and a mixing chamber (2). The mixing chamber (2) is provided with a fuel gas inlet end (5), an air inlet end (28), and an outlet end (29). The outlet end (29) is connected to the combustion chamber (6). Multiple gas discharge holes (7) are formed in one side surface of the combustion chamber (6) in an axial direction. The locomotive (10) for spreading a waterproof coil in a hot melt manner improves the construction efficiency, reduces human power costs and reduces consumption of fuel gas.

Abstract: A burner and a method utilize a burner tile with an outer surface extending along the furnace wall and an inner surface defining a passageway. A fuel duct extends at least partially through the passageway and discharges fuel onto a burner head. The burner head forms a coanda-curved surface, wherein the fuel is directed onto the coanda-curved surface such that the fuel flows along the coanda-curved surface to the outer surface of the burner tile. There is an air channel defined by an outside edge of the coanda-curved surface and in fluid flow communication with the passageway such that air flows from the passageway through the channel to mix with the fuel so as to produce the combustible mixture.
