Thus the boiler fuel demand can be potentially reduced from 10% to 20% by economically recovering hot condensate. The proper design of condensate system requires detail knowledge about condensate piping network, different components of the system as well as various problems associated with condensate flow both in steam and condensate pipelines.

Sep 02, 2019 · The Effect of High Conductivity. The effects of high conductivity can be very damaging if you don't stem them early on. It's typically impossible to obtain completely pure water in a boiler. No matter the quality of your equipment, impurities will invariably seep into the water and begin to increase the water conductivity.

A black liquor recovery boiler has two main functions. On one hand, it generates steam from the heat energy liberated upon combustion of the organic constituents of black liquor burned in the boiler, whereby the recovery boiler serves as a steam boiler. On the other hand, the chemicals from pulp digesting - sulphur and sodium - are recovered

Jul 08, 2021 · The best way to save on fuel and electricity to your boiler is to reduce steam usage in your processes. Insulating piping and tanks heated by steam, for example, can significantly reduce steam usage, and therefore, fuel usage. High-pressure condensate systems can reduce steam usage at your deaerator AND fuel usage in the boiler.

In fact, it can be shown that the efficiency of fuel input is nearly 100 % or all of the fuel goes into generating steam. In a conventional boiler, it is a well known fact that increasing the excess air decreases the boiler efficiency. In a HRSG,the excess air is decreased by addition of fuel, which increases the efficiency.
