TECHNOLOGYIN ACTION New pressure instrument release from Kobold
BOFA takes intelligence to new level in the laser market
BOFA International has launched its latest generation intelligent operating system – iQ2. The platform, available on BOFA’s best-in-class AD Oracle laser industry system, features a host of functionality enhancements and innovations, including extended onboard data logs and real-time system condition visualisation. iQ2 also supports a colour touchscreen user interface, smart alarm configuration and remote system upgrades.
BOFA’s portable technology plays a critical role in high volume laser coding and marking produc- tivity as well as precision engraving processes, by removing potentially harmful airborne contami- nants from work environments and keeping high performance equipment free from particulate. Haydn Knight, Sales and Marketing Director at BOFA, said the innovations and enhancements available via the AD Oracle iQ2 strengthen the company’s global market position.

Kobold have released the latest version of their electronic digital pressure gauge; model MAN- SC for battery powered, and model MAN-LC for 24Vdc power with IO-link.
Outwardly, the two versions are similar in ap- pearance and share most of the screen func- tionality features which are now accessed via capacitive Touchpads, however, depending on the application and use, each instrument ver- sion may be defined differently. For example, the battery powered instrument defined as a Digital Pressure Gauge, while the 24Vdc version can be defined as a Digital Pressure Transmit- ter, which considering the innovative features of each version is rather simplistic, but it goes some way to define the natural application areas of the two versions.
Kobold’s previous Digital Pressure Gauge, the MAN-SD, remained in production for 23 years, proving a very robust and popular instrument. With that record of robustness and reliability in mind, Kobold carefully developed the new MAN-SC/LC instruments, prioritising these core values, but also incorporating the wishes of customers worldwide to produce a high-qual- ity digital pressure gauge which satisfies tradi-
tional user applications, but also reaches out to new industry sectors.
A key target requirement in Kobold’s design brief was not to exceed the retail price of the previ- ous model, which for a new innovative electronic instrument product manufactured in Germany was not an easy task for Kobold’s production engineers, however, the retail price remains the same, and we think this offers considerable value for money in the current global marketplace.

A steam boiler is just one part of an often complex and well-engineered steam system
A steam boiler is just one part of an often complex and well-engineered steam system that requires the correct ancillary equipment to ensure process uptime and system longevity. But what are these ancillaries for and why do we need them. In this article, Fulton’s Ruth Price looks into the products that turn a boiler into a fully-fledged process steam solution.
Boiler Sequencing Systems
The use of intelligent sequencing system can provide redundancy and reli- ability and also offer significant energy savings by automating start-up and shut-down procedures; controlling and optimising main steam header pressure or temperature; ensuring steam supply is controlled precisely for the required process; and balancing the load distribution across the boilers, thus eliminating extensive losses from repeated start/stop cycling of burn- ers as much as is feasibly possible.
Sequencing should be about more than just simply on/off or start-up control. An intelligent sequencing system should also consider steam sys- tem load conditions and match this to the most efficient combination of boiler capacity according to the process requirements. Load response and start-up times are also factors. For example, a boiler sequencing control system should be capable of knowing when running too many or too few boilers is having a negative effect on efficiency and productivity. It should be able to monitor and pre-emptively predict a sud- den surge in demand and boiler utilisation by monitoring existing boiler de- mands, system pressures and flow rates; therefore starting/stopping boilers appropriately depending on the process demands.
Fulton’s recently-launched SCOPE is a universal control system suitable for sequencing up to four steam boilers, which can be retrofitted to existing vertical and horizontal fuel-fired boiler installations, including Fulton’s own range of existing and planned products and those manufactured by other boiler OEMs.
Boiler Feedwater & Condensate Return Tanks
The optimum delivery of feedwater and collection of condensate is essen- tial to the correct operation of a steam boiler system.
Normally of stainless-steel construction, feedwater and condensate return tanks are used to store boiler feedwater and make-up water and are also the vessel that condensate is returned to. As part of an ancillary package, they are usually supplied on a stand which, by elevating the boiler feed water, reduces the risk of cavitating the boiler feed pump. They are also the meeting place for cold make-up water and condensate return; and it’s im- portant that the water within it is kept at a high enough temperature, and mixed well, to minimise the content of dissolved oxygen within the water, which will cause corrosion.
