The tubular heater is a crucial heating equipment used in the oil refining, petrochemical, coal chemical, fertilizer, and chemical fiber industries. It has become the heart of heating, cracking, and conversion reactions in processes such as crude oil, coal tar, asphalt, ethylene, gasoline, diesel, and lubricant hydrogenation refining; and hydrogen production. It plays a vital role in the production quality, product yield, energy consumption, and safe long-term operation of the entire facility. Its function in the production process involves utilizing the heat energy from high-temperature flames and flue gases produced by fuel combustion within the furnace to heat the high-speed flowing material (liquid, gas, or oil-gas mixture) in the furnace tubes, achieving the required temperature for subsequent processes or facilitating chemical reactions within the tubes. Compared to other industrial furnaces, the liquid or gas flowing within the furnace tubes is typically high-temperature, high-pressure, flammable, and explosive hydrocarbon substances; most heated media tend to coking inside the tubes; precise control of furnace and material temperatures is required; the heating method is direct flame heating; the primary fuel is flammable and explosive liquid or gas; it poses high risks with stringent operating conditions; and requires continuous long-term operation. Therefore, the tubular heater holds a pivotal position in oil refining and petrochemical production.
Selection Requirements for Tubular Heaters: Refining and chemical industry tubular heaters are customized equipment. Therefore, the manufacturing of the heaters is tailored to the customer's construction drawings, design data sheets, and relevant technical requirements, ensuring targeted design, production, supply, and installation to meet the diverse needs of different customers.
The composition of a tubular heating furnace: It mainly consists of five major parts: the radiant chamber, the convection chamber, the waste heat recovery system, the combustion system, and the air supply and exhaust system. The main auxiliary equipment includes the fan for air supply, the induced draft fan, and the air preheater.
