WA water analyzer

Overview
Equipment level

Faultless boiler operation is dependent on good water quality. The water analyzer continuously measures and monitors:

pH value of feed water
O2 content of feed water
Residual hardness of make-up water
pH value of boiler water

All data are transmitted to the SCO system control via the bus system. This means that all key water parameters - including the conductivities of the boiler water and condensate streams - are thus stored in the SCO.

Benefits

Reduced dosing agent consumption due to precise continuous measurement and control
Increased operating reliability due to analysis of measurement results
Automatic measurements save time
User is immediately notified of deviations to allow rapid action to be taken
Less damage caused by incorrect water parameters
Reduction in desalination and blow-down losses thanks to dosing according to individual requirements
Less make-up water, dosing agent and heating-up steam due to reduced desalination and blow-down losses

The analysis component contains the measuring modules:

TH-Control for measuring the residual hardness of the make-up water downstream of a water softening system
pH-Control for measuring the pH of the water inside up to 3 boilers and in the boiler feed water
O2-Control for measuring the O2 content of the boiler feed water
In lower area: sample preparation with flow-through coolers for feed and boiler water plus control valves for control and distribution of the individual media

The electronic component consists of:

Power supply
Electronics for the measuring modules
Communication processors for data exchange between WA und SCO

Construction

The water analyzer consists of an analysis component and an electronic component, each housed in a wall-mounted case and connected with one another ex works.
