Description
The FSA/FSA-X elements represent the universal compact decision in the field of chimneys.

They have one or several channels of withdrawal of products of burning which are manufactured of stainless steel, 1.4571 mm thick. Besides, these designs have a layer of thermal insulation, not less than 1,5 mm thick which is placed on inside of an external pipe. Fasteners of a design do not interfere with an easy access of products of burning. Chimneys of FSA/FSA-X have multilayered thermal insulation which, for reduction of heatlosses is mounted with an overlap in places of joints. The external layer of designs is covered with aluminum foil which is excellent vapor barrier.

It should be noted that for ensuring the most effective ventilation, between the by-pass and bearing pipes there is a ring gap. This element, besides the paramount function, can be used for aeration of all boiler room.

Design features of the FSA/FSA-X elements, allow to make chimneys even of big height. It became possible thanks to the fact that the bearing design undertakes only mechanical loadings. In other words, it is not exposed to either thermal, nor chemical influences.

The sizes of the bearing pipe can be calculated, having used a formula of calculation of wind loading. So, for example, if the external design is higher than 16 meters, or height relation to diameter turns out more than this value, then it is necessary to carry out additional dynamic calculations.

It should be noted that the FSA/FSA-X elements do not interfere with installation of the deflector, a noise suppressor or accelerating nozzle. For survey and maintenance, on the bearing pipe the special ladder is mounted.

The FSA/FSA-X elements can be used in:
  • boiler rooms;
  • combined heat and power plants;
  • units of emergency power supply;
  • industrial furnaces.
