Improve steam boiler processes and save costs
Reduce steam, water and energy, simplify service and maintenance
With qualitative monitoring and control of feed water boilers and steam boilers
Companies should always produce their products flexibly and on time. The production processes are optimized accordingly to meet these challenges. In order to ensure an overall economical and flexible driving style of the entire production chain, upstream processes also have to be adapted.
The flexible production of sufficient quantities of steam for the manufacture of products is absolutely necessary. But in practice the operation of the steam boiler is mostly rigidly set. The dosing amounts of inhibitors are fixed set to the maximum amount of steam required to ensure safe steam production. With reduced steam production, there are rather unnecessary losses of energy and water. Because when less steam is produced, the vapors remain open and the dosage is not reduced.
With qualitative monitoring and control of the steam boiler, the costs of water, energy and carbon dioxide are reduced. And that with consistently flexible and secure production processes.
Intelligent monitoring of the steam boiler with an optimized control system
improves the efficiency of the boiler system with less costs and losses.
Save steam vapor
Losses previously ignored can contribute to detectable savings in boiler operation.
In practice, the vapor valve of feed water boilers must be kept open to guarantee thermal degassing. However, oxygen-free water enables a vapor valve to be closed if these requirements are met. So steam losses are reduced to the most necessary. With a qualitative monitoring of the dissolved oxygen content in the feed water and an automatic control of the vapor valve, unnecessary water and energy losses are prevented. Furthermore, in connection with the dosing control for the oxygen binder, an unnecessary salting-up of the feed water (up to 10 mg / l sodium sulfide) is prevented. There is also an improvement in the thickening in the steam boiler and a reduction in blowdown. This saves fuel, treated process water and carbon dioxide and the entire process is more efficient.

The rigid dosage setting for agents for oxygen binding and alkalization for maximum production of steam have negative consequences. Because with reduced production of steam, much less chemicals are required.
A pH value of 9 to 10 in the feed water is quite possible and legally permissible. However, the consumption of chemicals increases up to 10 times. This results in an up to 10 times increase in energy and water losses.
Permanent monitoring and control of pH, residual oxygen and conductance enables a reduced dosage of inhibitors to a necessary minimum. The result is less loss of energy and water in the steam boiler. At the same time, the efficiency of steam boiler operation improves and carbon dioxide emissions are also reduced.

The results from the tables will differ in practice, since not all concrete conditions can be taken into account in this form. These results should be your first decision-making aid for optimizing and increasing the efficiency of your steam boiler system.
