COMBUSTION CYLINDER CONSTRUCTION FOR OIL SPACE HEATER OF THE TYPE OF RADIATING HEAT RAYS

摘要

A combustion cylinder construction for an oil space heater of the type for radiating heat rays is disclosed which is capable of uniformly red-heating an outer surface of an outer cylindrical member of a double combustion cylinder and efficiently radiating heat rays from the red-hot outer surface and is capable of completely burning an incomplete combustion gas and the like at a flame spreader to form a white-yellow flame and afficiently radiating heat rays from the flame. The outer cylindrical member has through-holes larger than those of an inner cylindrical member and is provided at the upper portion thereof with a recess having through-holes. The combustion cylinder and flame spreader are surrounded by a single heat-permeable cylinder.
