During recent years, industrial chimneys have undergone remarkable developments, not only in their structural design, modelling and method of analysis, but also in the materials used and the methods of construction. In this sense, it should be noted the outstanding height increase as a result of better control of environmental pollution in populated areas. With the increase in height, seismic action and wind have become important in order to produce drive voltages in this particular type of continuous structures, so it is necessary to study the vibratory nature by performing a dynamic analysis. If a chimney is modelled as in a projected beam embedded in the base and free at its upper end, considering the behaviour of the linear elastic material, capable of deforming only by the effects of bending and shearing, and also has geometry Properties (area , Inertia, etc.) that vary with height, we will obtain differential equations of motion that apply to both free and forced vibrations that can not be solved exactly. Only for certain laws of geometric properties of variation is it possible to express the solution of the differential equation of motion based on known functions, as has been amply demonstrated in the literature on the subject.
The design of the steel chimney can be made as two types: 1.Self-supporting steel chimneys 2.Fireplaces made of steel. Self-supporting steel chimneys: When the lateral forces (wind or seismic forces) are transmitted to the foundation by the cantilever action of the chimney, the chimney is known as a freestanding chimney. The self-supporting fireplace with the base remains stable in all working conditions without any additional support. A self-supporting chimney is shown in Fig. The self-supporting chimneys are up to 10 m in diameter and 50 to 100 m high. Fireplaces of steel guyed: In tall steel chimneys, steel cables or soft steel individuals are united to transmit lateral forces. Such steel chimneys are known as guyed steel chimneys. In steel driven chimneys, all externally applied loads (wind, seismic force, etc.) are not fully transported through the chimney. These attached types or ranches share these loads applied. These guys or ranches ensure the stability of the guyed steel fireplace. These steel chimneys can be provided with one, two or three sets of individuals. In each set of boys, three or four or sometimes six wires are attached to the necklaces. When using a boy set, then the boys will attach to a necklace at a third or a quarter of the height from the top. When more than one set of types are used, they are used at different heights. A particular type of steel chimney is selected depending on the advantage and the disadvantages with reference to the economy. A choice between the self-supporting and guyed steel fireplace is made considering some of the important factors. The number of units, the type of equipment and the type of fuel to be used are considered. In case the boiler chimney is used, the surface, output efficiency, draft requirements, etc. will be taken into account. The mode of operation of the equipment will also be considered. The temperature of the flue gases is studied before entering the chimney and its probable variation. The type of coating is chosen by knowing the composition of the flue gases. The specific gravity, the amount of dust and the data on the aggressiveness of the combustion gases must be known. The factors that must be taken into account for the selection of a type of steel chimney are local legal provisions, relating to height, ash dispersion, anticipation of ground warning lamp, health, etc. . Erection mode is also considered. |
