Lecture 15C.5: Chimneys

Bochicchio, Victor A. The addition of Wet Flue Gas Desulphurization WFGD systems to existing coal fired power plants, and at several new plants, has resulted in the installation of over 90 FRP chimney liners in concrete chimneys during the past 6 years. The lower flue gas temperatures in power plants with WFGD increases corrosion concerns for chimney lining materials and often leads to the selection of FRP as the liner material of choice. Although the design and manufacture of the FRP liner is usually performed by a specialty FRP supplier, the integration of the liner into the overall chimney design and arrangement, and the prescription of many of the requirements for the design of the FRP liner are the responsibility of the chimney supplier. This paper explores various features of FRP liners and chimneys, how they relate to each other and the factors affecting decisions made during the design and installation process. Proper, timely coordination and communication between the chimney supplier and the FRP liner supplier generally results in a well-designed and successful chimney project.

CIC1ND is not, nor are any of its members, to be held responsible for any failure alleged or proved to be due to adherence to recommendations or acceptance of information published by a Model Code or in any other way. As a means to this end, a subcommittee was appointed in , charged with drafting a proposal for a model code for steel chimneys which reflected the current state-of-the-art and a consensus of views, internationally. This document was published in , with Commentaries being published the following year. Since , the science and technology of chimneys has advanced and in , CIC1ND appointed a committee to revise the Model Code, recognizing current best international practice and knowledge. The revision of the Model Code refers to the wind loads, both in along-wind and across-wind direction.

A chimney is an architectural ventilation structure made of masonry, clay or metal that isolates hot toxic exhaust gases or smoke produced by a boiler , stove , furnace , incinerator or fireplace from human living areas. Chimneys are typically vertical, or as near as possible to vertical, to ensure that the gases flow smoothly, drawing air into the combustion in what is known as the stack, or chimney effect. The space inside a chimney is called the flue.

To outline the specific characteristics of wind loading of chimneys; to give current methods for shell buckling calculation; and to outline the importance of tolerances. Lecture 15C. The specific aspects required in the calculation of actions are introduced, in particular, wind loads and the dynamic effects in the wind direction and perpendicular to the wind direction, and temperature loads.
