Boiler feed water quality

 

BOILER OPERATION AND PERFORMANCE

Boilers in any process plants is considered as a heart to its continuous operations, any unwanted stoppage or breakdowns leads to heavy loss to the plants. Therefore good performance of boiler is necessary to any process plants. We now discuss what are various parameters which can affect its performance and efficiency.

1. FEED Water Quality
2. F.D, I.D, and S.A. Fans.
3. Combustion
4. Quality of fuels used.
5. Grate area, Furnace area and Furnace volume.
6. Heat recovery units such as APH and Economiser.
7. pollution control units such as MDS and ESP.

In this post we will discuss the feed water quality

for maximum failure cases in boiler operation and its performance is because of poor quality of feed water. high pressure boilers and turbine house are integrated parts of distilleriey plants. poor quality water leads to scaling of tubes, drum inner side, drum internals and feed pipes. The scaling of boiler pressure parts affects its operational efficiency to large extent. it affects heat transfer from fuel to water, lower quantity and quality of steam generation which leads to more consumption of fuel and thereby lesser efficiency. The first and foremost point to consider is therefore the feed water quality.
Hence to have good quality of feed water one must have good water treatment plant
A simple soft water plant is sufficient for a small low pressure boilers used in chemical process plants with out steam turbine. however for a distilleriey plants which requires high pressure boilers with steam turbine one has to consider a D.M.plant  in series with softener plant.
the idea to have a softener plant before D.M plant is to have longer life of D.M Plant
and to some extent lesser times of regeneration cycles of D.M plant. Apart from having water treatment plant  one must have deareter to increase the water temperature 105 degrees and above to remove dissolved oxygen and other unwanted gases from feed water to keep heating surfaces clean and reduce erosion.
we hereby conclude water quality topic
for boiler operations.
For draught fans topic we will consider in the next post.
