Bullet Cleaning of Condensor And Heat – Exchanger Tubes
Water formed scaling and Bio Fouling stands as a major burden while operating cooling
water equipments and such fouling causes severe heat-transfer problems in addition to
impacting the asset life of heat exchanger/condenser systems.
Bullet Cleaning involves the use of specialized spring loaded tube cleaners (bullets)
that are shot through the fouled condenser tubes using specially designed water guns at
10-15 kg/cm2 pressure. The bullets move through the tube from one end to the other in a
linear motion scraping off the deposits and corrosion scales. Water from the gun flushes
out the scraped deposits resulting in a clean inside surface for the tube, ideal for
good heat transfer.
