BOILERS PUMPS & VALVES FEATURE Microturbines reduce steam operating costs
Spirax Sarco has launched a range of pressure-reducing microturbines that generate electricity to reduce utility costs for steam system operators. Suitable for saturated or superheated steam, Spirax Sarco TR Steam MicroTurbines are available in sizes up to 700 kW. Higher electricity outputs are available. A microturbine producing 300 kW of
electrical power can generate cost savings of more than £150,000 per year. The greater the steam demand, the more electricity the turbine will generate and the faster the payback. Generally, higher pressure steam
distributed from a boiler is conventionally lowered by a pressure reducing station to match the needs of the heating or process application.
REDUCING PRESSURE With a Spirax Sarco TR Steam MicroTurbine the steam is reduced to the required pressure as it travels through the turbine with the energy released by the pressure drop being used to generate electricity. Industries with potential for using the microturbines include food and drink, chemical processing, pharmaceutical and any facility with a pressure reduction requirement.

MicroTurbines enables them to be fitted into many existing steam systems and they are supplied fully assembled and tested to minimise on-site disruption. Each installation is supported by a full
set of Spirax Sarco expert services starting with an analysis of the site and calculations of projected savings.
SAVING ENERGY In addition to saving energy, microturbines help to reduce a facility’s carbon footprint. A microturbine system will often be installed in parallel with a conventional pressure reducing station. The unit is usually sized for a baseload
(for example, in the summer) so a pressure reducing station will still be needed to cope with peak loads or seasonal demands. Furthermore, this arrangement allows
the microturbine to be taken off line for maintenance without disrupting productivity. Spirax Sarco TR Steam MicroTurbines can operate at up to 89 bar g and 550°C.
The electricity produced can be used
locally or exported and sold to the mains power grid. The compact design of TR

Byworth Boilers offers an unprecedented level of visibility and control over everything in your boiler house from water treatment, right through to the steam header in one easy to use interface. Capable of handling dozens of simultaneous I/O, Unity is suitable for any boiler house from control of a single boiler to complex multi- boiler, multi- fuel installation incorporating waste heat and composite boilers.
Intelligent decisions based on the systems measured values are made to ensure efficient plant operation and reduce operational stress to decrease downtime and increase the plants life cycle. Unity is able to accept, process and trend various boiler house values including -
■ Boiler pressure ■ Manifold pressure ■ Boiler water level ■ Boiler water conductivity ■ Hotwell level ■ Hotwell temperature ■ ■

THE USER INTERFACE
Accessible via the built-in touch screen or remotely via TCP/IP on a Microsoft Windows based desktop PC; the easy to use interface allows for quick access to trend data, alarm logs, and user controllable functions such as time sequencing, fuel switching, or set point adjustment. A simple green, amber, red warning system ensures that the operators attention is quickly drawn to the changes in the condition of the plant. User configurable trends allow operators to assign any system value to trend on separate operator stations.
CONNECTIVITY
Remote control and monitoring is available via Modbus or TCP/IP as standard with other protocols available on request. The
integration of Modbus throughout makes communicating with burners, inverter drives and field based meters for example extremely simple bringing the full wealth of information from these devices to a central point for processing. A log of alarms and tests carried out is stored on the local device and can be output to a network printer on the triggering of such an event (such as an alarm or the completion of the boiler weekly test).
THE BOILER HOUSE
Unity was developed to monitor and control an entire boiler house installation from one central control point giving the system a significant advantage over using several third party controllers to operate different parts of the boiler house. The networked structure above shows a brief overview of some items that can be controlled and by what means of communication. As standard the unit will allow the operator to program and monitor the following through the HMI.
■ Time scheduling ■ Selectable setback pressures ■ Night setback ■ Automated two stage cold start ■ Trending of measured values ■ Logging of alarms ■ Automated water level tests ■ Pump automatic rotation ■ Blowdown Times ■ Hints to possible fault causes
