FIELD: oil and gas production.
SUBSTANCE: method includes preheating of pipes to 450-500°C with blowdown by water vapour along with movement of produced products and subsequent additional heating of pipes with sections to 700-850°C with subsequent displacement of the heating area. According to the invention, the heating zone is moved in direction from the outlet section to the inlet section of the furnace coil.
