Water-tube boilers and auxiliary installations - Part 8: Requirements for firing systems for liquid and gaseous fuels for the boiler
SIST EN 12952-8:2022

1.1   Firing systems
This document specifies requirements for liquid and gaseous fuel firing systems of steam boilers and hot water generators as defined in EN 12952-1:2015.
These requirements also apply to firing systems of chemical recovery boilers (black liquor boilers) with the additions and amendments specified in Annex A.
These requirements also apply to gas turbines in combination with fired/unfired heat recovery steam generators with the additions and amendments specified in Annex B.
NOTE 1   This document is not applicable to coil type boilers (flash boilers/small boilers) that use burners in accordance with EN 12953-7 for single burner installations.
NOTE 2   This document is not applicable to the storage of liquid fuels and to transfer stations of long-distance gas pipelines.
1.2   Fuels
This document specifies requirements which cover the use of liquid and gaseous fuels as defined in this document. Fuels deviating from standardized commercially available types can require additional or alternative safety measures. For black liquor these safety measures are given in Annex A.

Water-tube boilers and auxiliary installations - Part 16: Requirements for grate and fluidized-bed firing systems for solid fuels for the boiler
SIST EN 12952-16:2022

1.1   Firing systems
This document applies to atmospheric fluidized-bed and grate firing systems of steam boilers and hot water generators. These systems commence at the fuel bunkers and end at the ash extraction plant. For combination of various firing systems, the individual requirements of each system apply, especially those included in EN 12952-8:2022 and EN 12952-9:2022.
If several fuels are burnt simultaneously or if a fuel quality varies considerably (e.g. moisture content), additional safety measures can be necessary, especially with respect to limitation of the fuel flow into the firing system and ensuring proper air supply to the individual fuels.
Pressurized firing systems can require enhanced safety measures, which are not given in this European Standard.
1.2   Fuels
This document covers the use of solid fuels. Pulverized fuel fired in an entrained air flow (burner) system is covered by EN 12952-9:2022.
Solid fuels covered are:
•   all coal qualities, e.g. lignite or brown coal, sub-bituminous or hard brown coal, bituminous coal or hard coal, pitch coal, anthracite, coke, coal culm, coal sludge;
•   other fossil solid fuels (e.g. peat, oil shale);
•   biomass solid fuels (e.g. wood, wood wastes [bark], pellets, energy plants [miscanthus], harvest wastes [straw] and briquettes);
•   municipal waste solid fuels (e.g. garbage, sewage sludge, refuse derived fuels [RDF]);
•   industrial waste solid fuels (e.g. petrol coke, soot, tyres, paper wastes, coated wood chips, spent wood, animal product wastes).
Fuel blends from two or more groups, or fuels of unconventional or unknown quality can require special safety measures which can be proved either by practical experience gained from comparable fuels, or by suitable tests, e.g. in accordance with EN 14034-2:2006+A1:2011. Such measures specified and documented by the manufacturer.
Fuels on which the design is documented in the operating instructions (see 11.2). This includes the fuel data for 100 % input of the basic fuel and the data for any supplementary fuels together with their maximum thermal input percentage.
1.3   Operation
The requirements for operational equipment in Clause 4, Clause 5, Clause 6, Clause 7, Clause 8, Clause 9, Clause 10 and Clause 11 apply to steam boilers and hot water generators with permanent supervision by properly trained personnel familiar with the special conditions of the firing systems and the type of fuel.

Water-tube boilers and auxiliary installations - Part 9: Requirements for firing systems for pulverized solid fuels for the boiler
SIST EN 12952-9:2022

1.1   Firing systems
This document applies to pulverized fuel firing systems of steam boilers and hot water generators and commences at the filling equipment for the boiler bunkers or for the pulverized fuel storage system and ends at the ash extraction plant. For multifuel firing systems using separate or combined burners, these requirements apply to the pulverized fuel firing part involved. For other fuels or firing systems used in combination, other requirements apply, e.g. EN 12952-8:2022.
1.2   Fuels
These requirements cover the use of pulverized fuels (e.g. coke, anthracite, bituminous coal or hard coal, lignite or brown coal, petrol coke, oil shale and pulverized bio mass) ranging from low to high volatile matter content.
1.3   Operation
Requirements for operational equipment apply for steam boilers and hot water generators with permanent supervision by properly trained persons.
As firing systems using pulverized fuel can be designed either as direct-firing or as indirect-firing systems, operational requirements have to be differentiated. Annex A summarizes the operational requirements for firing systems including the pulverizing system.

Water-tube boilers and auxiliary installations - Part 1: General
SIST EN 12952-1:2016

1.1   General
This European Standard applies to water-tube boilers with volumes in excess of two litres for the generation of steam and/or hot water at a maximum allowable pressure PS greater than 0,5 bar and with a temperature in excess of 110 °C as well as auxiliary installations (other plant equipment).
The purpose of this European Standard is to ensure that the necessary essential safety requirements according to Annex I of the Pressure Equipment Directive are fulfilled in order to guarantee the safety of water tube boilers.
This aim will be achieved by:
-   the proper application of the design, manufacturing, testing and inspection methods and techniques,
-   the provision of protective measures against hazards, which cannot be eliminated, and
-   the provision of information on residual hazards and other measures to reduce risk,
which are incorporated in the various parts of this European Standard.
The requirements of this European Standard take account of pressure-related hazards, which apply to water tube boilers, including failure of pressure-retaining components due to overheating.
This standard recognizes that it is not possible to cover all the combinations of situations that might arise.
1.2   Boiler assembly
For the purpose of this European Standard, the boiler assembly includes:
-   the water-tube boiler including all the pressure parts from the feedwater inlet (including the inlet valve) up to and including the steam and/or hot water outlet (including the outlet valve or, if there is no valve, the first circumferential weld or flange downsteam of the outlet header);
-   all superheaters, reheaters, economizers, that are not capable of isolation from the main system by interposing shut-off valves, associated safety accessories and interconnecting piping;
-   additionally, the piping that is connected to the boiler involved in services such as draining, venting, desuperheating, etc., up to and including the first isolating valve in the tubing line downstream of the boiler;
-   reheaters which are independently fired, and are separately provided with their safety accessories including all control and safety systems.
The following equipment and components can be integrated in the assembly at the discretion of the manufacturer:
-   isolatable superheaters, reheaters, economizers and related interconnecting piping;
-   the heat supply or firing system;
-   the means of preparing and feeding the fuel to the boiler including the control systems;
-   the means of providing the boiler with feedwater including the control system;
-   the pressure expansion vessels and tanks of hot water generating plant.
1.3   Other plant equipment
a)   The boiler supporting structural steelwork, the thermal insulation and/or brickwork and the casing;
b)   the means of providing the boiler with air including the forced draught fans and air pre-heaters which are heated by the gases of combustion;
c)   the facilities for moving flue gases through the boiler up to the stack inlet, including the induced draught fans and the air pollution reducing equipment located in the flue gas removal path;
d)   all other equipment necessary for the operation of the boiler plant.
1.4   Exclusions
This European Standard does not apply to the following types of boiler plant:
a)   boilers other than stationary boilers;
b)   shell type boilers;
c)   electrical boilers;
d)   nuclear primary circuits, the failure of which can cause an emission of radioactivity.
