2 Terminology
2.01 Heating furnaces for the petroleum industry refer to special equipment for heating crude oil, natural gas, water and their mixtures with flames in oil and gas fields and long-distance pipelines. According to the structural type, they can generally be divided into fire tube heating furnaces and tubular heating furnaces. 2.02 Fire cylinder heating furnaces refer to a type of heating furnace that is surrounded by a metal shell on the outside and has a fire cylinder inside to transfer salt.
2.0.3 Rocket direct heating furnace refers to a fire-type heating furnace that directly heats raw materials such as water and their mixtures through a fire tube. 2.0.4 Fire-type indirect heating furnace refers to a fire tube heating furnace that heats crude oil, natural gas and their mixtures in the coil through an intermediate heat carrier. The intermediate heat carrier is water, which is referred to as a water jacket furnace.
2.0.5 Tubular heating furnace refers to a heating furnace that directly heats crude oil, natural gas, water and their mixtures in the furnace tube with flames, referred to as a tubular furnace. 2.0.6 The pressure components of the fire tube type heating furnace refer to the simplified, head, fire tube,: smoke tube heating coil, hole reinforcement plate, equipment flange, equipment main bolt manhole cover above M36, manhole method, manhole pipe and pipe with a true diameter of 250mm, etc. 3 General provisions
