Clyde Bergemann Power Group: Product Sectors - Cleaning Systems

		Intelligent Sootblowing

The demand on international fossil fuel based power
generators is to improve plant efficiency and availability as
well as to reduce their environmental impact. With our
advanced on-load boiler cleaning technology Clyde
Bergemann can assist power plant operators in meeting this
challenge.

During the past several years we have introduced
various new boiler cleaning solutions that have recently
been integrated in our SMART Clean ISB Platform.

Both economic and environmental necessities make it necessary to increase boiler efficiency and the plant heat rate, by means of reducing dry gas losses, as well as reducing furnace exit gas temperature (FEGT). These facts create the demand for a targeted and high effective boiler cleaning.

The performance of the on-load boiler cleaning system has a significant impact on the overall performance of the steam generator. Fouling and slagging in the furnace as well as in the convective heat exchanger zone leads to a reduction in boiler efficiency and reduction in availability such as

increase of furnace exit gas temperature

increase of attemperator spray rate

increase of boiler off gas temperature

damages in the hopper area and the wet/dry bottom ash system as a result of big slag
formations falling down from the furnace walls or/and superheater

unplanned boiler shut downs

over-cleaning causes tube damage negatively effecting unit availability

All this shows quite clearly that the important criteria for a modern on-load boiler cleaning solution ist to act flexible but selectively.

This means to clean

as early as necessary
as little as necessary
only in required areas
as effective as needed

With the SMART CLEAN ISB PLATFORM Clyde Bergemann offers an integrated solution which provides INTELLIGENT CLEANING to meet these demands.
