Analysis of operating costs

To keep the fuel costs of a boiler system as low as possible, the annual degree of utilisation achieved in practice is important. To be able to draw conclusions about the overall operating costs, the cost of the electrical energy required to run the fans and pumps, the waste water and water disposal costs and ultimately also the expenditure for operating, maintenance and inspection costs must also be considered.

The following topics should be considered when performing an overall assessment:

• The energy and mass balance of the boiler
• The energy and mass balance of the complete steam system including water treatment, all pipework, all consumers and the condensate system
• Maintenance and operational effects on the system
• Optimisation options through combination with additional technologies such as combined heat and power or solar heat
