Abstract
The utility model discloses a square box heating furnace with a built-in coil pipe radiation wall in a radiation chamber, relating to a heating furnace. The square box heating furnace comprises a square box type furnace body, a radiation chamber, a furnace tube, a convection chamber and a chimney, wherein the top of the furnace tube in the radiation chamber is arranged from two sides to the middle part to form a trench shape, a radiation wall is transversely arranged in the trench, and coil pipes are arranged at the periphery of the outer wall of the radiation wall. The radiation wall is tubular, the section of the radiation wall is in an inverted trapezoid shape, and observation holes are arranged in the waist surfaces on two sides of the inverted trapezoid. The square box heating furnace with a built-in coil pipe radiation wall in a radiation chamber is reasonable in design, has a simple structure, and fully utilizes the space of the radiation chamber by adding the radiation wall in the furnace body on the premise of not changing the total structural dimension of the original furnace body. The heat exchange area is enlarged in a limited space, and the radiant emittance of the radiation chamber is raised, so that the smoke discharge temperature of the radiation chamber is greatly lowered, and the heat efficiency is improved, therefore, the heat load of the heating furnace is effectively improved, equipment investment is reduced, the comprehensive efficiency of the heating furnace is effectively improved, and the production capacity of the device is improved.
Description
Technical field
The utility model relates to heating furnace, relates in particular to the built-in coil pipe radiant wall of a kind of radiation chamber square chest heating furnace.
Background technology
In the petrochemical industry process; Heating furnace is the most basic, imperative equipment; Simultaneously also be 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 comparable size structure, it is particularly important that the thermic load of raising heating furnace shows.According to present science and technology development present situation, the heat exchange area of heating furnace radiation chamber boiler tube and the thermic load of petrochemical industry heating furnace are closely bound up.Because the heating-furnace case takies finite volume; The surface heat intersity limitation of boiler tube fixes on certain limit; Can not infinitely increase, therefore improving the boiler tube heat exchange area of heating furnace radiation chamber and radiance, the raising boiler tube surface evenly heat intensity on boiler tube top is to improve the effective way of heating furnace thermic load.And the inner boiler tube layout of existing heating furnace radiation chamber is unreasonable, does not make full use of square chest upper furnace space, makes the interior heat transfer area of burner hearth less, and most of flue gas has directly got into convection cell through overshoot again; Limited the production capacity of device; Publication number is CN201382691, and patent name is the Chinese patent document of square chest tubular heater taper tube side spatial arrangements high efficient radiation chamber, is the device that designs to the problems referred to above; Solved effectively that heat transfer area in the burner hearth is less, the problem of inefficiency of production; But, practice finds that it still has deficiency, though heat transfer area has improved much in using; But the amount of radiation on boiler tube top is not enough, still influences the production capacity of device.
Summary of the invention
The utility model is intended to overcome the deficiency of prior art, and the built-in coil pipe radiant wall of a kind of radiation chamber square chest heating furnace that provides.
The built-in coil pipe radiant wall of the radiation chamber of the utility model square chest heating furnace; Be to constitute by square chest type body of heater, radiation chamber, boiler tube, convection cell and chimney; The top of the boiler tube of radiation chamber constitutes the trench shape by arranging in the middle of two side direction, in its trench the horizontal radiant wall that is provided with, arranging coil pipe in the outer wall ring week of radiant wall.
As the further improvement of the utility model, described radiant wall is a tubular, and its cross section is for trapezoidal.
As the further improvement of the utility model, be provided with peephole on falling trapezoidal both sides central plane in the cross section of radiant wall.
The built-in coil pipe radiant wall of the utility model radiation chamber square chest heating furnace, reasonable in design, simple in structure, be under the prerequisite of original body of heater general structure size constancy, make full use of the radiation chamber space through in body of heater, setting up radiant wall.In limited space, increase heat exchange area; Also increased the radiance of radiation chamber; The big spoke degree of radiation chamber exhaust gas temperature is reduced; Thereby the thermal efficiency is improved the thermic load that improves heating furnace effectively, reduce equipment investment, improve the overall efficiency of heating furnace effectively, improved the production capacity of device.
