Abstract

The invention belongs to the technical field of tubular heating furnaces and discloses a tubular heating furnace with efficient and uniform heating, and the tubular heating furnace is used for solving the problem that a current tubular heating furnace is uneven in medium heating. The tubular heating furnace comprises a tubular furnace body, wherein a combustion chamber and a heat exchange chamber are arranged in the tubular furnace body; one end of the tubular furnace body is a combustion chamber inlet which is communicated with the combustion chamber; the other end of the tubular furnace body is a smoke exhaust opening which is communicated with the combustion chamber; the tubular furnace body, close to the combustion chamber inlet, is provided with a heated medium outlet; the tubular furnace body, close to the smoke exhaust opening, is provided with a heated medium inlet; the heat exchange chamber, the heated medium inlet and the heated medium outlet are communicated with one another; the combustion chamber comprises an outer combustion chamber and an inner combustion chamber; the outer combustion chamber is arranged on the inner wall of the tubular furnace body in a sleeving mode; the inner combustion chamber is mutually communicated with the bottom of the outer combustion chamber; the tops of the inner combustion chamber and the outer combustion chamber are communicated with the smoke exhaust opening; and the heat exchange chamber for medium heating is formed between the inner combustion chamber and the outer combustion chamber.

Description

technical field [0001] The invention belongs to the technical field of tubular heating furnaces, and specifically discloses a high-efficiency and uniform heating tubular heating furnace. Background technique [0002] Tubular heating furnace is a process heating furnace used in petroleum refining, petrochemical, coal chemical, tar processing, crude oil transportation and other industries. The flow medium of the heated material in the tube is gas or liquid; and they are all flammable and explosive substances. , the operating conditions are harsh, and at the same time, it operates continuously for a long period of time, and the heating method is directly exposed to fire. The exhaust gas temperature of the tubular heating furnace can be reduced to about 100°C to realize partial condensation of the acid-containing water vapor in the flue gas, and while recovering the low-temperature sensible heat of the flue gas, part of the latent heat of vaporization of the acid-containing wate...
