The heating furnaces used in petroleum chemical plant equipment all heat oil or other fluids through pipes. For simplicity, it is usually referred to as a heating furnace or just a furnace. 2. What is a naturally ventilated heating furnace? A heating furnace that uses the suction force of a chimney to draw in combustion air and exhaust flue gases is called a naturally ventilated heating furnace. 3. What is a forced-air heating furnace? A heating furnace in which the air required for fuel combustion is supplied by a ventilator, and the flue gases are expelled through the chimney under negative pressure, is called a forced-air heating furnace. 4. What is a negative-pressure heating furnace? A heating furnace that uses an exhaust fan to remove flue gas, maintain a negative pressure inside the furnace, and draw in combustion air is called a negative-pressure heating furnace. 5. What is a draft-balanced heating furnace? A heating furnace in which air is supplied by a ventilator and smoke gases are expelled by an exhaust fan is called a draft-balanced heating furnace. 6. What is draft force? Draft force is the negative pressure of the flue gas measured at any point within the heating furnace. 7. What is heat conduction? Heat conduction refers to the transfer of heat that occurs as a result of direct contact between different parts of an object. 8. What is convective heat transfer? Convective heat transfer refers to the transfer of heat from one part of a space to another through the movement of liquid or gas particles from one place to another. 9. What is radiation heat transfer? Radiative heat transfer is a process in which energy is transferred through electromagnetic waves. 10. What is the furnace body of a heating furnace? The furnace body refers to the collective term for the heating furnace’s outer shell, brick lining, refractory materials, insulation materials, including insulation nails as well.
