JOINT STOCK COMPANY of "Mosenergo - Moscow Regional Administration of
Power System Management" completes the repair of chimney stack at State Regional Electric Power Plant -5. Reconstruction assumes the introduction of the new technological
solutions and contemporary materials, which will increase the ecological parameters and several times will prolong the period of operation.
The old technology of the surface protection of chimney stacks adapted
Until now in the power system. On this technology the internal surface of the chimney stacks of power stations will be bordered by the layer of special lining brick ("brick
lining"), which protects the ferroconcrete stem of pipe from the action of
products of combustion. The brick lining of chimney stacks is worn out in the course of time, and one time in several years is required conducting the expensive
repair work with the stoppage for a prolonged time of basic power
equipment.
In the course of repair at State Regional Electric Power Plant -5 brick, brick lining will be substituted to the metallic gas-bleeding stem, knots of which are prepared at the Chekhovian plant "hydro-steel" from highly technological types of alloy corrosion-resistant steel of the
type "korten". For the specialists of energy company one must solve complex
technological problem, since the removal of old brick lining and the installation of metallic
coating will pass at the height of 180 m.
Metallic stem possesses a number of the unquestionable advantages. First, it is completely gasproof, i.e., practically it does not pass flue gases to the ferroconcrete
stem. In the second place, metallic stem is more long-lived. Thirdly, in the space between the stems it will be built circular areas and stairs, which make it possible to conduct constant observations of the state of chimney stack. As a result of reconstruction several times will grow the period of the operation of chimney stack.
Installation of metallic stem in the chimney stacks of power stations
- comparatively new technology. For the first time in its power system they used in 1998 on TETs-21. In further JOINT STOCK COMPANY of "Mosenergo - Moscow Regional
Administration of Power System Management" it plans to enlarge the
practice of the application of metallic shielding it is trunk at other
power stations of energy company. |
