Abstract
The utility model discloses a square box heating furnace with a built-in 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; the top of the furnace pipe in the radiation chamber is arranged from two sides to the middle part to form a trench shape, and the radiation wall is transversely arranged in the trench. 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 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. As the radiation wall is added in the original space, the heat absorption quantity at the upper part of the radiation chamber is increased, the smoke discharge temperature in 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 radiant wall square chest of a kind of radiation chamber 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 raising of heating furnace radiation chamber boiler tube top calorific intensity and the thermic load of petrochemical industry heating furnace are closely bound up.Because box type heater radiation chamber upper space is bigger, the flue gas major part directly gets into convection cell, flue gas is smaller to the radiation of top radiating furnace tube, and the evenly heat intensity on boiler tube top does not obtain due raising.Therefore the calorific intensity that improves heating furnace radiation chamber boiler tube top is to improve the effective way of heating furnace thermic load.And existing square chest heating furnace radiation chamber top does not have radiant wall; The radiating furnace tube upper and lower temperature difference is bigger, the boiler tube mean intensity is lower; Particularly the used square chest stove thermic load of petrochemical industry is all bigger, and problem is just more outstanding, has limited 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 radiant wall square chest of a kind of radiation chamber heating furnace that provides.
The built-in radiant wall square chest of the radiation chamber of the utility model heating furnace is to be made up of square chest type body of heater, radiation chamber, boiler tube, convection cell and chimney, and the top of the boiler tube of radiation chamber constitutes the trench shape by arranging in the middle of two side direction, the horizontal radiant wall that is provided with in its trench.
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 radiant wall square chest of the utility model radiation chamber 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 original space, increase radiant wall; Thereby increased the caloric receptivity on radiation chamber boiler tube top; 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.
