PROBLEM TO BE SOLVED: To provide a delayed coking heater which does not generate an unnecessary precipitate of carbon in a conduit of a coker heater, and heats a raw material to desired decomposition temperature.SOLUTION: A delayed coking heater 10 comprises: a heater comprising a heating section 14 of radiant heat having a lower part having a blast furnace bottom burner part including plural blast furnace bottom burners 46 disposed adjacent to a blast furnace bottom 42 for heating the heating section 14 by radiant heat; and plural heat coils 26 which are disposed on the heating section 14 by the radiant heat and are bent in parallel to a vertical direction. The plural heat coils 26 which are bent in parallel, include plural channel conduits which are disposed so that, continuous channels of a horizontal cylindrical tube are reciprocated in front and rear directions and horizontally extend in parallel, in which the continuous channels extend from at least two inlets disposed on an upper part of the heating section 14 of the radiant heat of the heater to at least two outlets disposed on a lower part of the heating section 14 of the radiant heat of the heater. |
