Requirements for the boiler room and boiler installation
(User | Installer)
In Poland, boiler houses built for solid fuel should meet the requirements of PN-87/B-02411 "Boiler houses built
for solid fuel" and OJ. 2015.0.1422. They are divided into two types:
1. For small boiler plants up to 25 kW capacity, the following requirements should be met:
●
The boiler should be positioned as centrally as possible to the rooms to be heated and in a separate
room;
●
The boiler should be placed on a foundation made of noncombustible materials, projecting 0.05 m
above the floor level and edged with steel angles;
●
there should be artificial lighting in the room, and natural lighting is also advisable;
●
the position of the wheel in the room should allow free access to the boiler for cleaning and
maintenance; the distance from the back of the boiler to the wall should not be less than 70 cm, from
the side of the boiler to the wall not less than 100 cm, and from the front of the boiler to the opposite
wall not less than 200 cm;
●
the height in new buildings should be at least 220 cm, in the case of existing buildings the height of the
boiler room should be at least 190 cm, with proper ventilation (supply and exhaust);
●
Supply ventilation should be by means of an unsealed opening with a minimum cross-section of 200 cm
2
and located up to a maximum of 100 cm above floor level;
●
the exhaust ventilation should be realised through an exhaust duct made of non-flammable material,
with a minimum cross-section of 14 x 14 cm with an inlet opening under the ceiling of the boiler room;
the exhaust duct should be led above the roof and placed near the chimney; there must be no devices
on the exhaust duct allowing to close it;
●
the section of the chimney should not be smaller than 20 x 20 cm;
●
there should be a floor drain in the floor of the boiler room;
●
The optimum place for storing fuel is in a separate room close to the boiler room;
●
ash and slag must be collected in suitable containers for daily emptying.
2. Boiler plants with a heat output of 25 kW or more should additionally meet the following requirements:
●
The distance of the boiler furthest from the chimney, with gravity draught, must not exceed 50 cm of the
chimney height;
●
The fuel store and slag store should be located next to the boiler hall at a storage height of up to 220 cm
with a minimum of 50 cm free space above the fuel;
●
facilities and equipment must be included to allow vertical and horizontal transport of fuel and slag;
●
the fuel store room shall have natural unforced ventilation, providing for one complete change of air per
hour in the fuel store and three complete changes of air in the slag store;
●
the entrance door to the boiler room should be non-combustible (class 0.5 fire resistance), minimum
width 80 cm, opening outwards; it should have a handleless locking system allowing it to open outwards
under pressure, inwards using the handle;
●
the ventilation requirements are the same as for boiler rooms with smaller outputs; in addition, in boiler
rooms with outputs in excess of 400 kW there should be, in addition to supply and exhaust ventilation,
