Sahoma Controlware's offering of a intelligent Combustion Control System, is a turnkey, mass flow air/fuel ratio control system for industrial burners. The system is comprised of five components that integrate easily with a conventional burner management system and pipe train (Control Panel, Air Valve Actuator & Fuel Valve Actuator, Air Flow Control, and Flow Control).
The Control Panel includes a Burner PLC, 24 VDC Power Supply, and HMI Display. The Burner PLC contains all of the factory-installed, combustion
intelligence (such as burner-specific air/fuel ratio and flow data), enabling the system to be easily commissioned after field installation. The HMI Display allows the Operator to monitor and adjust the performance of the combustion system. The Valve Actuators are factory-calibrated assemblies that include rugged, high-quality planetary gearheads and stepper motors for highly repeatable and precise control of butterfly valves. The Air and Fuel Flow Control are integrated into Burner PLC each consist of a precision-calibrated thermal mass flow sensor, control electronics, and flow body with integrated flow conditioners for a highly repeatable measurement.
Other system functions include fuel totalizing, air/fuel flow and valve position analog outputs for DCS interfacing, (optional) remote monitoring, and many redundant system safety functions. The Standard system specifications are as follows:
Valve Position: Control 0.1 angular degree resolution
Flow Control: ± 1% of flow reading over a turndown of 20:1
Air/Fuel Ratio Control: ± 2% with turndown of 20:1
Power Supply Input: 100-120 VAC @ 2.5 Amps max, 50-60 Hz, 200-240 VAC @ 1.5 Amps max, 50-60 Hz
Ambient Temperature: -20°F to 122°F (-29°C to 50°C)
4-20 mA I/O: Output: 350 Ohms max user load resistance
Input: 20 mA max current, 250 Ohm input resistance
ControlRelays: Input Coil: 120 VAC @ 7.5 mA, 240 VAC @ 3.8 mA
Output Contacts: 250 VAc @ 10 Amps, 30 VDC @ 10 Amps
A Burner Management System (BMS) is a safety solution for power generation facilities that enables the safe start-up, operation, and shut down of the multiple-burner furnace section of a boiler. It reduces maintenance, improves up-time, and provides a safe environment for the boiler and plant personnel.
What Is It?
Highly reliable Safety Systems applied to Power Boiler and Recovery Boiler Burner Management applications can improve plant uptime, reduce ownership costs and ensure regulatory compliance compared to relay or general purpose Programmable Logic Controller (PLC)- based applications. A typical solution may also provide protection for the boiler water circulation pump, replacement of the master fuel trip (MFT) relay, and link the burner management system of the auxiliary boiler to the main burner management system.
Sahoma Controlware offers Safety platforms provide up to SIL 3 TÜV approved Burner Management System solutions that cover requirements according to the National Fire Protection Association (NFPA) 85 & 86 standards and European EN 50156-1.
How does It work?
A burner management system is responsible for the safe start-up, operation and shutdown of a boiler. It monitors and controls igniters and main burners; utilizes flame scanners to detect and discriminate between the igniter and main flames; employs safety shut-off valves, pressure, temperature, flow and valve position limit switches and uses blowers to cool the scanners and/or provide combustion air for the igniters. Its proper operation is crucial to the safety of a boiler.
What Problems Does It Solve?
Sahoma Controlware's BMS Solution improves plant uptime, reduces total cost of ownership and ensures regulatory compliance compared to relay or general purpose PLC-based applications. It also improves personnel safety by removing the need to access old relay boxes located in high temperature areas of the boiler.
balance of plant
Sahoma Controlware Balance of Plant (BOP) control system solution is a programmable plant control system for new applications or as a replacement for an existing plant controller such as a distributed control system (DCS). The BOP Control System uses the same controller and I/O platforms and communications on a common bus sharing all plant parameters.
Typical Systems Include But Not Limited To:
Liquid Fuel Treatment/Forwarding/Storage
Gas Fuel Compression
De-mineralized Water Treatment
Plant Instrument Air
Plant Cooling Water Systems
Traditionally the Gas Turbine Control Systems were autonomous and connected to the rest of the plant via a communications link. With the advances in communications options, I/O types and the capabilities of programmable controllers, Sahoma Controlware implements solutions to where the Gas Turbine Control Systems can be a fully integrated component in an overall Balance of Plant Control System.
