<\/a>\n\t\t\t\t\n\t\n<\/div>\n\n\nAt present, there exist four main types of industrial chimneys:<\/p>\n
- \n
- ferroconcrete (90 – 200m high);<\/li>\n
- brick (25 – 100m high);<\/li>\n
- metal;<\/li>\n
- bimetal, chimneys built from composite materials.<\/li>\n<\/ul>\n
Most chimneys (ferroconcrete, brick) are fitted with a whole row of operating equipment including:<\/p>\n
- \n
- light platforms;<\/li>\n
- stairs;<\/li>\n
- electric light fittings (signal lights);<\/li>\n
- lightning protection;<\/li>\n
- clamping rings (brick chimneys);<\/li>\n
- combustion product filtration system etc.<\/li>\n<\/ul>\n
The average operating lifespan of ferroconcrete chimneys is 40 years. In order to prolong the lifespan and to maintain operational state of the construction a set of restoration works is required.<\/p>\n
MONTEX PLUSS possesses extensive experience, qualified specialists and technologies to provide solutions to these problems.<\/p>\n
Condition survey:<\/h2>\n
- \n
- condition of the protective concrete layer, cracks, peeling, bare reinforcement bars etc.<\/li>\n
- condition of chimney head;<\/li>\n
- condition of staircase reinforcement, light platforms, lightning protection, signal lights etc.<\/li>\n
- internal condition survey, condition surveys of backing, drip belts, the volume of ashy deposits etc.<\/li>\n
- gas flue survey, tightness of gas flue linking to the chimney.<\/li>\n<\/ul>\n

<\/a>\n\t\t\t\t\n\t\n<\/div>\n\n\nSimilarly to other industrial constructions and because of their operational specificity, chimneys are particularly exposed to various damaging factors.<\/p>\n
The operational lifespan of ferroconcrete chimneys varies from 40 to 50 years and at present most of these constructions have reached the state of deterioration and are subject to dismantling. <\/p>\n
However, whereas the technology of erecting ferroconcrete chimneys is rather developed, little attention has been paid to the development of dismantling technologies.<\/p>\n
In cooperation with our partners from Germany, we provide solutions for the whole set of issues related to the dismantling of high-rise constructions. The German company offers a wide range of technological schemes and corresponding equipment designed for conducting dismantling works of both brick and ferroconcrete chimneys.<\/p>\n
The technologies of dismantling totally exclude methods involving explosives or collapsing techniques.<\/p>\n
To date, in cooperation with the German partners, MONTEX PLUSS has successfully and within short terms completed the dismantling of a 150 m high ferroconcrete chimney located on the territory of the Baltic Power Plants in Narva. Kohtla-J\u00e4rve chimney – equally belonging to the Baltic Power Plants – dismantling project is currently being developed.<\/p>\n","protected":false},"excerpt":{"rendered":"
