Abstract
The utility model provides a square box heating furnace with radiation coil pipes mounted at the top of a radiation chamber, and relates to a heating furnace. The square box heating furnace includes a square box type furnace body, the radiation chamber, furnace tubes, a convection chamber and a chimney, wherein the tops of the furnace tubes inside the radiation chamber are arranged to form a saddle shape from the two sides to the middle; radiation heat pipe columns are transversely placed inside the saddle of the radiation chamber; and the radiation heat pipe columns are transversely twisted in the radiation chamber. The square box heating furnace with the radiation coil pipes mounted at the top of the radiation chamber provided by the utility model has reasonable design and simple structure, makes full use of the space of the radiation chamber through additionally arranging the radiation heat pipe columns inside the furnace body under the premise that the overall structural size of the original furnace body is unchanged, enlarges the heat exchange area in the limited space as well as the radiance of the radiation chamber to greatly reduce the stack gas temperature of the radiation chamber and improve the heat efficiency, thereby greatly improving the thermal load and equipment investment, and effectively improving the combined efficiency and the production capacity of the device.
Description
Technical field
The utility model relates to heating furnace, relates in particular to a kind of radiation chamber overhead radiant coil 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 improve the boiler tube heat exchange area of heating furnace radiation chamber and boiler tube top radiance, improve boiler tube surface evenly heat intensity, reduce convection cell boiler tube quantity, make full use of the effective way that radiation chamber high potential heat is a raising heating furnace thermic load.And the inner boiler tube layout of existing heating furnace radiation chamber is unreasonable, does not make full use of furnace cavity, makes the interior heat transfer area of burner hearth less, has limited the production capacity of device; Publication number is CN201382691; Patent name is the Chinese patent document of square chest tubular heater taper tube side spatial arrangements high efficient radiation chamber, is to the problems referred to above and design apparatus, has solved effectively that heat transfer area in the burner hearth is less, the problem of inefficiency of production; But, practice finds in using; It still has deficiency, and heat transfer area does not reach maximization, still influences the production capacity of device.
Summary of the invention
The utility model is intended to overcome the deficiency of prior art, and a kind of radiation chamber overhead radiant coil square chest heating furnace that provides.
The radiation chamber overhead radiant coil square chest heating furnace of the utility model; Be to be made up of 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, the horizontal radiant heat that is provided with is restrained in its trench.
As the further improvement of the utility model, described radiant heat tube bank laterally coiling arrangement in radiation.
As the further improvement of the utility model, the arrangement cross section periphery of described radiant heat tube bank is for trapezoidal.
The utility model radiation chamber overhead radiant coil 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 radiation push pipe bundle.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 and improves the thermic load of heating furnace, minimizing equipment investment by a relatively large margin effectively, improves the overall efficiency of heating furnace effectively, has improved the production capacity of device.
