Boiler
fouling sensors
Heat flux sensors can be used to detect fouling in industrial boilers. A
sketch of the principles is given below.
A
heat flux sensor (1) is incorporated in the waterwall of a boiler (2). By
measuring the flux as a function of time, the process of soot accumulation
can be followed (3). The heat flux sensor functions as a slagging and fouling sensor.
This sensor type can also be applied in intelligent sootblowing
applications. The principele is similar to that of Land Fluxdomes
(As previosly manufactured by Land Combustion).
Hukseflux
cooperates on the subject of intelligent sootblowing with Clyde
Bergemann Power Group.
The
water cannons of Clyde Bergemann in combination with heat flux sensors and
the appropriate software, offer the optimum solution for automation of the
(otherwise manually controlled) sootblowing process in electrical power
plants.
The
first installations indicate that by improving heat transfer between
furnace and wall, savings in fuel of between 1 and 2 % can be attained.
Additional benefits are in increased lifetime of tubing (sootblowing is
done only if and where necessary) and reduction of workload for
personnel.
