The explanation of boiler safety distance

The installation of the boiler and the construction of the boiler room are big projects. Basically, there is no need to consider where to put it or how to install it like a normal household appliance .
However,Only when the safety distance between the boiler and other buildings is guaranteed, the boiler can be safely “started”.

Safety distance of boiler in boiler room
The clearance between the boiler and the internal walls of the boiler house shall meet the space required for the furnace operator to operate, overhaul and arrange the auxiliary machinery.

1. The distance before the furnace:

Steam boiler 1 ~ 4t / h, hot water boiler 0.7 ~ 2.8MW, not less than 3.0m;

Steam boiler 6 ~ 20t / h, hot water boiler 4.2 ~ 14MW, not less than 4.0m;

Steam boiler 35 ~ 65t / h, hot water boiler 29 ~ 58MW, should not be less than 5.0m.

When the pot pipe needs to be replaced in front of the furnace, the clean distance in front of the furnace should meet the operational requirements. For steam boilers of 6 to 65 t/h, hot water boilers of 4.2 to 58 MW, when the furnace control is equipped with the instrument control room, the clearance from the front end of the boiler to the instrument control room can be 3 m.

2. The clearance of the channel on the side and back of the boiler:

Steam boiler 1 ~ 4t / h, hot water boiler 0.7 ~ 2.8MW, should not be less than 0.8m;

Steam boiler 6 ~ 20t / h, hot water boiler 4.2 ~ 14MW, should not be less than 1.5m;

Steam boiler 35 ~ 65t / h, hot water boiler 29 ~ 58MW, should not be less than 1.8m.

In addition, when it is necessary to blow ash, set fire, remove slag, install or repair the spiral slag remover, the clear distance of the passage should meet the requirements of operation. It should be added that the distance between the highest operating point of the boiler and the lowest structure at the top of the boiler room should not be less than 2 m.

Safety distance between boiler and production workshop

Boiler houses and workshops are not allowed to be connected and must be independent, generally more than 5 meters, or they can be separated by fuel storage.

 

Safe distance between boiler room and building

1. The safety distance between the boiler room and a type of high-rise building is 15 meters: one type of high-rise refers to 9-16 floors (the height is up to 50 meters);

2. The safety distance between the boiler house and the multi-storey residential building is 13 meters: multi-storey buildings refer to houses of 2-9 floors and other civil buildings with a height of not more than 24m;

3. The safety distance between the boiler room and the podium is 10 meters: the height of the podium connected to the high-rise is generally not more than 24m.
