3.2 Boiler room
Boiler room must be secured against freezing.
The support surface of the boiler in the boiler room must be of non-combustible
material. Recommended distance of all four sides of the boiler in relation to the
boiler walls or other solid body (water heater, etc.. ) are shown in Figure 6. These
values allow a safe distance access when firing, sufficient space for cleaning and
easy access to fan and valve for filling and emptying. Boiler at its left hand side
should be away from the wall 100 to 200 mm i.e. as much as needed for the
connection of valves for thermal safety by over flow. If the valve is not to be
installed then the space can be smaller. The flap handle for firing is removable and
can be placed either on the left or right side of the boiler. The space on the right side
of the boiler, which is recommended to be at least 800mm from the silo is important
because after cleaning the boiler the user then goes and pulls out the ashtray from the
back of the firebox. Boiler room must have sufficient ventilation holes for fresh air
as well as for the outlet of the exhaust air.
Figure 6. Positioning of boiler in the Boiler room
Total space of this openings is minimum 150cm² fro the boilers of the power of
50kW and for the power over 50kW the space must be larger for another 2cm² per
1kW.
A=150cm²+
= possible power of over 50kW.
The lack of sufficient ventilation in the boiler room can cause more problems in the work of boiler.
Main problem is the inability to achieve high output water temperature i.e. the lack of maximum
power which leads to condensation in the boiler.
