Water test boiler

maintenance water boiler follow manual book and then depend about maker . usually the water boiler test twice of weekly.

rangen normal water boiler : 

- PH ( potensial hydrogen ) = 9 - 11 ppm 
-Chloride                                = 0 - 100 ppm
-P.alkalinity                            = 200 - 300 ppm 

water for boiler is important about perfomance boiler .

basic principal of boiler ,  the make a steam from boil water . 
boiler have 2 type 
1. fire tube
2.water tube

WATER TEST BOILER  
 
Normal range 
- PH               = 8,3 - 9.0 
  dose chemical condensate control if PH low 

-Chloride       = 0 - 100 ppm
 if more than 100 ppm  please blowdown more often  and keep chloride as low as possible.

-P.alkalinity   = 110 - 300 ppm
 if below 100 ppm please dose chemical Autotreat / Liquitreat at 1.2 ltr/ton of water  and maintain P.alkalinity is always between 100 -300 ppm to prevent scale formation 
 
-DEHA           = 0.08 - 0.3 ppm
if below 0.08 ppm Increase Oxygen scavenger Plus dose bu 25 % and maintain DEHA  0.08 - 0.3 ppm to prevent Oxygen corrosion and pitting.

-Phosphate    = 30 - 70 ppm
if below 30 ppm please dose Hardness treatment 0.75 ltr/ton . to prevent scaling.

-Hydrazine    = 0.05 - 0.2 ppm.
if below 0.05 ppm increase oxygen control dose 25 %. to prevent oxygen corrosion and pitting
