The boiler adopts an environmentally friendly combustion method - full premixed combustion, and the gas and air are precisely adjusted and premixed in advance to ensure more complete combustion.
The boiler adopts a double-drum longitudinal "D" type arrangement structure; water, steam or steam-water mixture flows in the pipe; flame burns and flue gas flows outside the pipe, forming extremely fast steam-water.
-tube have a limited surface area in the drum relative to the evaporation rate This results in very high release rates per unit of area and turbulence -tube tend to be higher rated perhaps over 1 000 tonnes/h of
analysis and control for correct operation There are several causes for whilst foaming; high levels of suspended solids high alkalinity or contamination by oils and fats but the most common cause of carryover (provided these other factors are properly controlled) is a high Total Dissolved Solids (TDS) level
The safe pH range for steam boilers is between 85pH & 127pH whilst the recommended level is between Boiler water with a pH of 105 contributes 126mg/l towards the boiler TDS whilst at a pH of 120 it increases to 400mg/l and at 125pH the value is 12649 mg/l a 100 fold increase
The pH should be maintained between a minimum of 105 and a maximum of 110 to prevent acidic corrosion of boiler tubes and plates and to provide for the precipitation of scale forming salts before scale is deposited Below a pH of the water is acidic enough to dissolve the steel boiler plates
Check pH before starting boiler knowing it has not mixed in well just yet pH should be between Promptly have the boiler operator operate the boiler to heat the cleaning solution in the boiler to a maximum of 130 F DO NOT BOIL THE WATER
pH Treatment Introduction Acidic and basic (alkaline) are two extremes that describe chemicals just like hot and cold are two Boiler pH Natural water is usually pH A common recommendation is to maintain boiler water at 85 Controlling pH For example Caustic Soda an
· Like virtually all power companies the utility treats its high-purity boiler water to a pH For many years the company used a specialized high-purity water sensor to
· It comes into play with steam boilers because a pH is just right If the pH is lower than that the water will start eating the pipes If its higher than that the water wont corrode metal but it may begin to foam and thats not good
