Abstract

The utility model relates to a spatially arranged tube high-efficient radiation chamber of a rectangular box body tube type heating furnace, which consists of a furnace body, a furnace wall, furnace tubes and a burner, wherein the plane section-view structure of the furnace body is in a rectangular shape, the furnace tubes are vertically arranged along the four sides of the furnace wall of the furnace body, every two lower ends of the furnace tubes are in U-shaped connection, every two upper ends of the furnace tubes along the short edge of the rectangle are in U-shaped connection, and the upper ends of the furnace tubes along the long edge of the rectangle are correspondingly in bridge connection with the furnace tubes on the opposite edge to form the spatial arrangement of the radiation chamber. The spatially arranged tube high-efficient radiation chamber of the rectangular box body tube type heating furnace has the advantages of reasonable design and simple structure, the heat exchange area of the furnace tubes is increased by additionally arranging radiation furnace tubes in the furnace body on the premise without changing the overall structure of the furnace body, the space of the radiation chamber is fully utilized, the radiation rate of the upper part of the furnace tube of the radiation chamber is increased, so the thermal load of the heating furnace is effectively improved, the equipment investment is reduced, the comprehensive efficiency of the heating furnace is increased, the heat exchange area of the furnace tubes is enlarged, and the productive capacity of the device is improved.

Description

Tubulation high efficient radiation chamber, rectangular box tubular heater space

Technical field

The utility model belongs to the heating furnace radiation chamber, particularly relates to tubulation high efficient radiation chamber, a kind of rectangular box tubular heater space.

Background technology

In the petrochemical industry process, heating furnace is the most basic, imperative equipment, it simultaneously also is the key equipment that petrochemical industry production capacity size is played decisive factor, the thermic load size of heating furnace is the working ability of decision petrochemical equipment directly, therefore, under the situation of equal contour structures, it is particularly important that the thermic load of raising heating furnace shows.According to present science and technology development present situation, closely bound up with the thermic load of petrochemical industry heating furnace is that the heat exchange area of heating furnace radiation chamber boiler tube is (because of the surface heat intensity of boiler tube is limited to certain limit, can not infinitely increase), the boiler tube heat exchange area that therefore improves the heating furnace radiation chamber is the unique feasible effective way that improves the heating furnace thermic load.And existing heating furnace radiation chamber has influenced heat exchange area because its inner boiler tube layout is unreasonable, has limited the production capacity of device.

Summary of the invention

The utility model is intended to overcome the deficiencies in the prior art, and tubulation high efficient radiation chamber, a kind of rectangular box tubular heater space is provided.

Tubulation high efficient radiation chamber, rectangular box tubular heater of the present utility model space is to be made of body of heater, furnace wall, boiler tube and burner.The plan cross-section structure of body of heater is a rectangle, boiler tube is U-shaped connection in twos along the vertical arrangement in four limits, its lower end of the furnace wall of body of heater, upper end along rectangle minor face boiler tube is U-shaped connection in twos, and along the upper end and the corresponding cross-over connection of the boiler tube of opposite side of the long limit of rectangle boiler tube, arrange in the space that constitutes radiation chamber.

Tubulation high efficient radiation chamber, rectangular box tubular heater of the present utility model space, reasonable in design, simple in structure, be under the constant prerequisite of body of heater general structure, in body of heater, set up radiating furnace tube and increase the boiler tube heat exchange area, make full use of the radiation chamber space, also increased the radiance on radiation chamber boiler tube top, thus improve effectively heating furnace thermic load, reduce equipment investment, improve the overall efficiency of heating furnace, strengthen the heat exchange area of boiler tube, improved the production capacity of device.
