Waste incineration plants

Special functions are available in seavis for waste incineration plants (referred to below as "WIP"):

  • Start-up and support mode

  • Purge suppression

  • Cooling programs

Configuring the plant as a WIP

Type of plant

The operation modes are automatically configured for start-up and support mode.

Start-up and support mode

Different fuel-air ratios can be configured in seavis for start-up and support mode.

  • Start-up mode

    In start-up operation mode, the combustion chamber is heated up for the combustion of garbage.

  • Support mode

    If the temperature in the combustion chamber is insufficient for complete combustion of the garbage, then the system switches to support mode in order to maintain the required minimum temperature.

Switching between start-up and support mode

Operation mode switching between start-up and support modes is performed by using the "waste incineration plant support mode" input, which must be contained in the FSC input configuration.

Operation modes

Separate operation modes are required respectively for start-up and support mode. These operation modes are permanently assigned in pairs. As a result, the number of operation modes for operation of a WIP is reduced to operation modes WIP-1 through WIP-4.

Example

Operation mode MVA-1 (Oil):
Oil start-up operation mode
Oil support mode
(= Operation mode 1)
(= Operation mode 2)
Operation mode MVA-2 (Gas):
Gas start-up operation mode
Gas support mode
(= Operation mode 3)
(= Operation mode 4)
Operation mode MVA-3 (X):
X start-up operation mode
X support mode
(= Operation mode 5)
(= Operation mode 6)
Operation mode MVA-4 (Y):
Y start-up operation mode
Y support mode
(= Operation mode 7)
(= Operation mode 8)

You have to assign the fuels and compound channels in pairs for start-up and support mode:

Example

Operation mode MVA-1 (Oil):

  • Fuel 1 = Oil

  • Channel 1 = Oil flow controller

  • Channel 3 = Secondary air control damper

    Oil start-up operation mode
    {1296} "Fuel 1: Active in operation mode 1" = TRUE
    {1080} "Channel 1: Activate in operation mode 1" = TRUE
    {1112} "Channel 3: Activate in operation mode 1" = TRUE
    Oil support mode
    {1297} "Fuel 1: Active in operation mode 2" = TRUE
    {1081} "Channel 1: Activate in operation mode 2" = TRUE
    {1113} "Channel 3: Activate in operation mode 2" = TRUE

Operation mode MVA-2 (Gas):

  • Fuel 2 = Gas

  • Channel 2 = Gas control damper

  • Channel 3 = Secondary air control damper

    Gas start-up operation mode
    {1306} "Fuel 2: Active in operation mode 3" = TRUE
    {1098} "Channel 2: Activate in operation mode 3" = TRUE
    {1114} "Channel 3: Activate in operation mode 3" = TRUE
    Gas support mode
    {1307} "Fuel 2: Active in operation mode 4" = TRUE
    {1099} "Channel 2: Activate in operation mode 4" = TRUE
    {1115} "Channel 3: Activate in operation mode 4" = TRUE

Purge suppression

As a rule, air is delivered to the combustion chamber in a WIP via the WIP control and communication system/WIP control system and not via the burner integrated in the plant.

If purging nevertheless has to take place via the burner, then this has to be parameterized:
