Nozzle Pressure (Analog Input 0) -in Bargraf form & in Real number value

Burner Flow (kg/h) (Analog Input 1 OR tacho signal Digital Input 0.0)
-in Bargraf form & in Real number value, this filed can be hiden if commissioning engineer want to have all adjustment done in the l/h.

Burner Flow (l/h) (Analog Input 1 OR tacho signal Digital Input 0.0)
-in Real number value, this ensures that we can see if we have correct input signal before calculation is performed into kg/h.

Indication of the Selected Fuel:
-HFO / MGO type of the fuel is selected, for this there is 2 field with text for indication

AIR RATIO input field
-ensures end user to be able to lineary make correction to the output +/- 20%

IGNITION FORCING AO Pressure
-This is used for indication that until Main Oil Valves are opened, Nozzle pressure is forcing as a analog output from the SBS-FMU unit. This is used on some systems which are checking that i.e. Nozzle pressure must be over 10kg/cm2 before opening of the Main Oil Valves. This option can be Enabled/Disabled in the Settings 4 screen and also delay alarms can be adjusted.

OUTPUT Type of forward signal
-This is indicating if current output is forward of FLOW or PRESSURE signal. Ensuring that commissioning engineer has information of the real output signal.

Alarm & Indication functions:
BACKFIRE Protection – Flow
-monitor that during MOV Opened (DI0.7) Flow thru nozzle is less then Sepoint Value in time interval defined in the Settings page. Value can be adjusted in the Settings screen. For which you need password.

BACKFIRE Protection – Pressure -monitor that during MOV Opened (DI0.7) Pressure of nozzle is less then Sepoint Value in time interval defined in the Settings page. Value can be adjusted in the Settings screen. For which you need password.

General description of the control system
Auto/manual station is analog output equipment which, in case of programmable analog controller (PAC) self-diagnosed an irreversible error, replaces PAC. Auto/manual station can freely increase and decrease analog output values. Auto/manual station is a follow-up type, which maintains and controls the last output value of PAC prior to the switch-over.

Specification
Auto/manual station has 10 digital inputs, 5 digital outputs, 8 analog input (0/4-20mA, 0-10V, 1-5V), 4 analog outputs (0/4-20mA, 0-10V, 1-5V) and touch panel with 4 function keys (MAIN, INDIC, ALARM and BACK) and 9 additional key for operation.

Main functions
1. Auto/manual mode of each Analog Input signal is switched by way of key operations, and their current modes can be confirmed on Touch screen.
2. Increase and decrease of each analog input can be controlled and put out separately.
3. Pac output value is put on hold at the time emergency output becomes OFF
4. Output values can be displayed real-time in digital or bar graph.
5. Cause of alarm is displayed

+MGO EmPostPurge, Marine Gasoline Oil Emergency Post Purge System
System is designed to ensure post purging in case of Flame failure during burner operation in Emergency mode. To avoid adding of new control element in Combustion Air damper control loop (4-20 mA from ACC) pneumatic solution is chosen for control during post purging in Emergency operation.

System consists of:

PLC & relays
PLC is monitoring burner mode of operation (auto/emergency), status of Main oil valves and both Flame scanners.

Pneumatic
Opening of Combustion air damper via solenoid valve V1 to position determined with Press regulator R1.

Valve V1 is spring return and in normal position air from damper I/P positioner is directed to control drive, when V1 energized air adjusted on press regulator R1 is forwarded to control drive.

For bypassing of pneumatic system V2 (control air shutoff) shell be closed and V3 (solenoid bypass) opened.

PLC (Siemens LOGO 230 RC) is powered from 230 VAC source permanently to avoid PLC start-up time at power-up (if connected to EMG. Operation power supply, certain time will be necessary for PLC to load program and establish RUN mode).

SBS PinClean

Unique Cleaning Device for Pin Tubes – Cleanse with the Power of Bubbles
Scandinavian Boiler Service is presenting the new SBS PinClean™. The SBS PinClean™ is the most suitable cleaning device for all oil fire boilers, composite boilers, etc. with pin tubes in the combustion chamber.

SBS Cleaning Plugs

SBS Cleaning Device for Uptake
In many composite or oil-fired boilers, the convection part consists of water tube uptake. These boilers are designed to have a high flue gas velocity through the tube nest in order to keep the tubes clean and efficiency high. If soot deposits are accumulated on the tube surface, this will result in less convection heat transferred to the water/steam, thus decreasing the efficiency of the boiler. Normally, this is shown as higher flue gas temperature and increasing pressure loss over the boiler.

Flame failure can occur because of back pressure from furnace room depending on the amount of flow that can pass inside the tubes. It is impossible to give an exact interval for when the tube nest should be cleaned as this depends on various factors such as oil quality, burner adjustments and operation load of the boiler. A visual inspection frequently inside the boiler is a good and most reliable method to check if cleaning of tube nest is necessary. It is always easier to maintain than to clean when the tubes are already blocked.
