Abstract
The invention provides a box-type heating furnace provided with a radiation chamber with overhead radiation coils, and relates to a heating furnace. The box-type heating furnace consists of a box-type furnace body, the radiation chamber, furnace tubes, a convection chamber and a chimney, wherein the top parts of the furnace tubes in the radiation chamber are arranged in a valley shape from the two sides to the middle part; and radiating heat tube bundles are transversely arranged in the formed valley and are transversely convoluted in the case of radiation. The box-type heating furnace has the advantages of reasonable design and simple structure, i.e., the top radiating tube bundles are additionally arranged in the furnace body so as to fully utilize the space of the radiation chamber on the premise of not changing the overall structure size of the original furnace body. Therefore, the box-type heating furnace has the beneficial effects that the heat exchange area is increased in a limited space and the radiation rate of the radiation chamber is also improved, thus greatly lowering the exhaust fume temperature of the radiation chamber, effectively improving the heat efficiency and the heat load of the heating furnace, greatly reducing the equipment investment, effectively improving the comprehensive efficiency of the heating furnace, and enhancing the production capacity of devices.
Description
Technical field
The present invention relates to heating furnace, relate 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 present invention is intended to overcome the deficiency of prior art, and a kind of radiation chamber overhead radiant coil square chest heating furnace that provides.
Radiation chamber overhead radiant coil square chest heating furnace of the present invention; 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 further improvement of the present invention, described radiant heat tube bank laterally coiling arrangement in radiation.
As further improvement of the present invention, the arrangement cross section periphery of described radiant heat tube bank is for trapezoidal.
Radiation chamber overhead radiant coil square chest heating furnace of the present invention, 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.
