Besides continuous blowdown intermittent blowdown
contributes to boiler safety and trouble - free operation.
Intermittent blowdown ensures that precipitated solids
and sludge are cleared from the boiler so that they
cannot accumulate in the bottom of the boiler.
A programme - controlled blowdown system with
rapid - action intermittent blowdown valve is used for
this purpose.

As a result of the evaporation process the salt content
in the boiler water increases continually.
To avoid deposits and carryover of salts into downstream
equipment caused by “foaming and priming”, the salt
content must be kept within the permissible limits. The
easiest and most reliable method is by continuous
blowdown.
Some hardening constituents may form suspended
matter that drops to the bottom of the boiler. Together
with other foreign matter they form a sludge layer which
has to be purged to prevent corrosion, reduced heat
transfer etc. For this purpose intermittent blowdown
has proved successful.

For efficient boiler operation with a high degree of
safety the following points are most important.
1 - A modern water - treatment plant, designed to meet
the specific requirements of the plant.
2 - TDS (total dissolved solids) control by continuous
measurements of the boiler water conductivity,
continuous and intermittent blowdown control.
Depending on the type of water treatment a certain
percentage of salts remains in the feed water. some of
these salts (in particular calcium and magnesium salts)
form, together with other impurities, the hardening
constituents in the water.

in the boiler water increases continually.
To avoid deposits and carryover of salts into downstream
equipment caused by “foaming and priming”, the salt
content must be kept within the permissible limits. The
easiest and most reliable method is by continuous
blowdown.
Some hardening constituents may form suspended
matter that drops to the bottom of the boiler. Together
with other foreign matter they form a sludge layer which
has to be purged to prevent corrosion, reduced heat
transfer etc. For this purpose intermittent blowdown
has proved successful.

For efficient boiler operation with a high degree of
safety the following points are most important.
1 - A modern water - treatment plant, designed to meet
the specific requirements of the plant.
2 - TDS (total dissolved solids) control by continuous
measurements of the boiler water conductivity,
continuous and intermittent blowdown control.
Depending on the type of water treatment a certain
percentage of salts remains in the feed water. some of
these salts (in particular calcium and magnesium salts)
form, together with other impurities, the hardening
constituents in the water.

Besides continuous blowdown intermittent blowdown
contributes to boiler safety and trouble - free operation.
Intermittent blowdown ensures that precipitated solids
and sludge are cleared from the boiler so that they
cannot accumulate in the bottom of the boiler.
A programme - controlled blowdown system with
rapid - action intermittent blowdown valve is used for
this purpose.
