Boiler selection should be based on design documentation of the boiler room.
|Specification||Unit||Type of boiler|
|NKP 07/60||NKP 07/115||NKP 07/160||NKP 07/250|
|Nominal thermal power||kW||60||115||160||250|
|Boiler’s heating surface||m2||9||16||24||32|
|Flux of steam (efficiency)||kg/h||90||170||240||375|
|Required flue gas drift||Pa||5,5||6,5||7,5||8|
|Approximate min. chimney height||m||6,5||8||9||9|
|basic fuel||–||hard coal 32,1 type, Oil sort, 24/12 class according|
to PN-82/G-97002, PN-82/G-97001, PN-82/G-97003
|Boiler’s weight without water||kg||700||1400||2100||3000|

Type of fuel recommended for NKP boilers:
Hard coal 32.1 type, OII sort, 24/12 class according to PN -82/G – 97002, PN – 82/G – 97001, PN -82/G – 97003
Use of worse quality coal will result in the drop of thermal efficiency, and operating would be much more labor – consuming.
