Abstract

PURPOSE: A tubular heating furnace, constituted of heat transfer tubes having a straight part and a spiral part heated from both sides, capable of heating a fluid to be heated efficiently, having high safety and durability, and capable of being easily large sized structure.
CONSTITUTION: A spiral elliptic heat transfer tube 14 in the longitudinal direction is provided in the central position of a combustion chamber 13 in the octagonal box-like body casing 10 having a cross section long in one direction. The heat transfer tube 14 consists of a straight part (14A) and a bent part (14B) having a central radius (r) of curvature 5 times or more, preferably 7.5 times or more, the inside diameter of (h) of the tube 14. A floor burner 16 is provided as the first heat source for heating the inner peripheral surface of the heat transfer tube 14, and a wall burner 17 is provided as the second heat source for heating the outer peripheral surface of the tube 14 to constitute the furnace. A fluid to be heated, e.g. a coal slurry in coal liquefying plants, is introduced from an inlet (14a) of the heat transfer tube 14, and heated while lowered from above downward in the heat transfer tube 14 to the outlet (14b).
