Waste Heat Boiler ECS Series

Computer loaded through-flow type waste heat recovery steam boiler
ECS Series

For diesel/gasoline engines
Evaporation amount : 200-1,400 kg/h
Corresponding generator : 400-3,000 kW

Through intelligent AI function, a more reliable steam is supplied
Display function makes it possible to prevent steam stop
Information and communication function makes it possible to establish a highly accurate online maintenance
Seven items corresponding to heat management for the boiler itself are shown in the panel

AI incorporated for an even more stable steam supply
A computer has been incorporated into the waste heat recovery boiler to ensure continued overall efficiency of cogeneration. A more detailed control allows highly efficient and stable waste recovery for a safe and extended useful life

Operation with a high level of safety and accuracy


Compared to traditional pressure switches, a more accurate control stabilizes the steam pressure. Automatic compensation of the boiler data according to steam pressure has made possible a more accurate control.	Monitoring of waste gas pressure activates by-pass operation in case of failure.	AI function carries out automatic drainage at a given flow rate, 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.

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. Multiple damper control	3. Counter flow avoidance control
2. Multiple water level control

Display function
Boiler Stop Preventive Measures
A large display shows the contents, and indicates the most effective maintenance measures to prevent steam stop.

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

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. Operation condition signal	4. Heat management signal
2. Message/Alarm signal	5. Parameters setting signal
3. Failure/event signal

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.

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

The standard line-up includes 10 models of ECS-D2 type for diesel engines, and 9 models of ECS-GC, GB, GX type for gasoline engines for a generator capacity of 400-3000 kW.
