Heaters

Heaters

Heat carriers
KSK: hot, superheated water;
KPSK: dry saturated steam

Design and Execution

The general for KSK and KPSK

• Heaters are speralno - nakatny, bimetallic
• Join system of the heat carrier by means of welding or by means of flanges

  KSK

  Execution on internal носителю: №№ 6 - 10 - six - running No. No. 11 - 12 - four - running The consecutive multiple - pass movement of the heat carrier is reached at the expense of partitions in collectors Are established in systems with a horizontal arrangement of the heatgiving elements

  KPSK

  Execution on the internal carrier: one - pass Have patrubkt on both sides Are established in systems with a vertical arrangement of the heatgiving elements

  Execution materials
  KSK: a steel pipe 16х1, 5 of carbonaceous steel and alyuminevy nakatny fins with a nominal diameter of 39 mm
  KPSK: a steel pipe 16х2, 0 of carbonaceous steel and alyuminevy nakatny fins with a nominal diameter of 39 mm

  Conditions ekspluatatsiiobshchy for KSK and KPSK

• Should not be established on the objects creating vibration with mean square value more than 2 mm / with
• In winter time start - up in work has to be carried out with a speed of rise in temperature no more than 30 °C an hour

  Only for KPSK

• Work of a heater on flying steam is not allowed
• Level of condensate should not be above a number of the heatgiving tubes
• In order that there was no through (flying) break of steam and at the same time there were no big speeds causing an erosion of walls of the heatgiving pipes on plum of condensate it is necessary to establish kondensatootvodchik of the corresponding number (on a rassotyaniye not less than 300 mm from the lower branch pipe of a heater)
• Removal of condensate has to exclude a possibility of defrosting of the air heater and emergence of hydroblows at change of loading
