Combined with the related fire-preventng standards

the danger-level in SCR reactor zone and in ammonia-preparing zone has been analysed

and an approach to concrete fire-preventing design of the denitrification system being made.Two spraying systems have to be installed in teh ammonia preparing zone

one spraying system for temperature-reducing and cooling uses the technological water

and the other spraying system uses the fire-fighting water.Thus

the danger-level of fire risk can be treated differenty

starting the spraying system up according to the demand

thereby

the consuption of fire-fighting water can be reduced.
