TP149 - Pravilnik o tehničnih zahtevah za obratovanje vročevodnih in parnih kotlov

This part of this European Standard specifies the essential requirements for equipment and protective devices for a water-tube boiler plant as defined in EN 12952-1, to ensure the boiler operates safely within the allowable limits (pressure, temperature, etc.).

This Part of this European Standard specifies the requirements for safety related equipment for shell boilers as defined in EN 12953-1, to ensure the boiler operates within the allowable limits (pressure, temperature, etc.) and if the limits are exceeded will interrupt and lock out the energy supply without manual intervention in the boiler house.

This part of the European Standard applies to all shell boilers as defined in prEN 12953-1 which are heated by combustion of one or more fuels or by hot gases for the generation of steam and/or hot water. This European Standard applies to those components between the feedwater inlet and the steam outlet of the steam generator. The quality of the steam produced is outside the scope of this standard.

This Part of this European Standard applies to those components between the feedwater inlet and the steam outlet of the steam generator. The quality of the steam produced is outside the scope of this standard.
This Part of this European Standard aims to ensure that the boiler is able to be operated to minimize risk to personnel, the boiler and associated plant components located near it.
NOTE   This European Standard does not aim to achieve optimum economic operation. For certain purposes, it will be more appropriate to optimize the chemical characteristics in order to:
- increase the thermal efficiency;
- increase the availability and reliability of the plant;
- increase steam purity;
- reduce the maintenance costs - repair, chemical cleaning, etc.
This Part of this European Standard sets out minimum requirements for the specific types of water to reduce the risk of corrosion, sludge precipitation or formation of deposits which may lead to any damage or other operating problems.
NOTE   This Part of this European Standard has been prepared on the assumption that the user of this European Standard possesses a sufficient knowledge of the construction and operation of the boiler as well as an adequate appreciation of water and steam chemistry.
