Boiler |
Microcomputer-contolled for Cogeneration
Waste Heat Boiler
|
A more stable steam supply through AI
A microcomputer has been incorporated into the waste heat recovery boiler to ensure continued overall efficiency of cogeneration. More precise control allows highly efficient and stable waste heat recovery for a safe and extended operating life. |

Operation with a high level of safety and accuracy
New Control Functions |
Steam Pressure Sensor
• A more precise control stabilizes the steam pressure, compared to traditional pressure switches.
• Automatic compensation for the boiler data according to steam pressure enables highly precise control.
|
Automatic control of water concentration
• AI function carries out regular automatic blowdown to remove the concentrated water,
keeping water concentration in the boiler at a set value. If water concentration in the boiler exceeds a set value,
the sensor detects it and automatic drainage is activated, water concentration in the boiler is thoroughly monitored.
Water concentration control is crucial for a high quality steam supply.
|
Waste gas pressure sensor
• Monitoring of waste gas pressure activates by-pass operation in case of failure.

AI Function
A more reliable steam supply
Control changes are carried out under strict safety measures, at the same time that steam stop is prevented, continuous engine operation is maintained.
|
|
| 1. Damper failure |
5. Feed water shortage |
| 2. Scale deposition |
6. Blow period |
| 3. Pump capacity decrease |
7. Water level electrode failure |
| 4. Soot deposition |
8. Other 30 items such as counter-flow |
Display Functions
Boiler Stop Preventive Measures
A large display shows the contents, and indicates the most effective maintenance measures to prevent steam stop. |
|
| 1. Operation condition signal |
4. Heat management signal |
| 2. Message/Alarm signal |
5. Parameters setting signal |
| 3. Failure/event signal |
|
Information and communication function
More effective Online Maintenance
Signal monitor allows easy assessment of current steam pressure,
exhaust gas pressure, and boiler electro-conductivity, making it possible to establish a highly accurate online maintenance. |
|
| 1. Steam output |
5. Feed water temperature |
| 2. Blow amount |
6. Operation time |
| 3. Exhaust gas temperature at inlet |
7. Operation counter |
| 4. Exhaust gas temperature at outlet |
|
Temperature control function
Seven items corresponding to heat management for the boiler itself are shown in the panel
In order to maintain a safe and stable operation, seven items, including steam output, blow amount are shown in the panel as operation data.
A simple and easy to see and understand display has been installed. Boiler conditions can be assessed at a glance. |
