Control and monitoring of a Fire-Tube Boiler

Overview

Control and monitoring of a Fire-Tube Boiler is often found in hospitals and most process plants that use steam either for process or building heating. The 6000 Series master communications opens up packaged solutions of recorders and controllers.

In this application the 2704 controls the water level and total dissolved solids (TDS). It also performs other boiler control functions such as Timed Bottom Blowdown and Steam Main Warm Up. A 6000A or 6000XIO is used to provide an HMI to the 2704 and act as a steam flow computer calculating the Saturated Steam Mass Flow. The 6000 can be directly connected to the factory Ethernet providing valuable energy management information.

• Water level

• Boiler Pressure

• continuous Total Dissolved Solids

• Main Steam Warm-Up

• Open Communications

• Flexible User Interface 

6000 series options have equations designed particularly for use with saturated steam. Mass Flow, Heat Flow and Heat Consumed can all be calculated and recorded. All of these equations can be set to use either pressure or temperature as the measured input and use look-ups from the 1999 ASME steam tables.

The 6000 Flow Computers are ideal for energy and facility management. They can be used to monitor energy performance and to identify problems as they occur as well as for energy cost allocation. Data can be presented and reported as required in Excel™ using Report software to access information from the secure process data files.

The 6000 Flow Computers have excellent communications capabilities allowing the units to be networked for data transfer to other systems or for remote access by the user, ensuring information is available wherever and whenever it is needed.

The 6000 series User Screens and Master Communications make them ideal for use as a data acquisition device & HMI to 2704 boiler controllers.
