IT-1 Energy's CBS Software is the most cost effective intelligent soot cleaning control system available. Through our the state of the art thermodynamic software models we can interface with any sensor array to track and calculate boiler heat transfer deterioration in real time, 24/7 in a large number of boiler tubes simultaneously and with the finest detail heat transfer mapping available in the market.
The cost reduction is achived through, decreased CO2 emissions, a reduction in tube erosion, increased efficiency, early detection of clinker build up, a reduction in shutdowns.
Total calculated savings, $2.8 million per year.
CBS Software models adjust in real time to:
- Variable power output.
- Flue gas tempreture.
- High spray water activation.
- Energy mass flow.
There are boiler efficiency benefits due to the following:
Results:
Efficiency improvement was monitored on line and improvement based by IT-1's observation of data from production was 0.5% improvement
- Fuel cost saving per year: 200MW x 8,000h x 0.30 $/MWh = $480,000
CBS Software is providing possibility for adjusting to any power output production requirement and optimum regime of operation in regard to fuel /coal consumption/CO2 emission versus tube erosion by controlling soot build up using continuous instrumentation data analysis and heat transfer deterioration calculation. By that minimum required soot blowing activation is required and as consequences minimum erosion is expected.
Erosion reduction benefits due to the following:
Shutdown benefits due to the following:
Erosion - time loss of production
Total calculated cost of loss in production revenue was $2,135,040
Note: not included is the cost of repair
CBS software early clinker detection provides opportunity for early corrective actions and reduced costs of shut downs as a result of clinker build up.
Clinker prevention benefits due to the following:
Results:
For example, shrinking of boiler is only conducted when necessary.
Clinkers shut down loss of production:
A total calculated saving of $533,760.00
The CBS Software is capable of executing the soot blowers automatically with or without operator’s intervention (as per configuration).
In addition, operators can manually request the CBS Software to populate the list of soot blowers to be activated based on the most recent data.
Results:
With automatic mode, CBS Software ensures no soot blowing will be missed and hence is capable of maintaining the plant at its highest efficiency.
CBS Software also completely eliminates the need for operator to manually populate soot blower for its execution sequence. Through semiautomatic mode, operator through a single click, will be able to request CBS Software to perform its analysis and populate the soot blowers which required execution most. This ensures all benefits provided by CBS are preserved even if manual intervention is required.
