Abstract

The utility model relates to a square box-shaped spatial net-shaped furnace tube high-efficient radiation chamber of a tube type heating furnace, which consists of a furnace body, a furnace wall, a burner, a radiation chamber and furnace tubes, wherein the radiation chamber is in a square box shape, the furnace tubes are vertically arranged along the four sides of the furnace wall in the furnace body, the bottom ends of the adjacent tubes of the furnace tubes are successively in U-shaped connection, and the tops of the furnace tubes are tube beams on opposite sides and in bridge connection one by one, wherein the two walls of the tops of the furnace tubes are correspondingly in bridge connection to form spatially arranged lattice-shaped furnace tubes of the radiation chamber with different heights. The square box-shaped spatial net-shaped furnace tube high-efficient radiation chamber of the 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 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

Netted boiler tube high efficient radiation chamber, square box shape tubular heater space

Technical field

The utility model belongs to the heating furnace radiation chamber, particularly relates to netted boiler tube high efficient radiation chamber, a kind of square box shape 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 netted boiler tube high efficient radiation chamber, a kind of square box shape tubular heater space is provided.

Netted boiler tube high efficient radiation chamber, square box shape tubular heater of the present utility model space is to be made of body of heater, furnace wall, burner, radiation chamber and boiler tube.Described radiation chamber is a square box shape, and boiler tube wall along furnace wall in body of heater is erect arrangement, and the bottom of each adjacent tubes of boiler tube is that two walls are restrained relatively one by one across connection for U-shaped connection in succession, its top.

As further improvement of the utility model, top two walls of boiler tube are corresponding across connecting, constitute the steric radiation chamber boiler tube of checked spun antung shape that highly differs.

Netted boiler tube high efficient radiation chamber, square box shape tubular heater of the present utility model space, double-layer horizontal intersection boiler tube is set at the top of radiation chamber, promptly enlarged the heat transfer area of boiler tube, reduce the heat flow rate per unit area of heating furnace, make full use of the high temperature heat radiation of radiation chamber flame again, can increase the radiation chamber heat exchange area more than 35%.

Netted boiler tube high efficient radiation chamber, square box shape 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.
