New gas analyzer gives tonic to the daily flues
Land Instruments International has launched the Lancom 200 as its latest portable gas analyser for measuring sulphuric acid dew-point temperature.
The UK-based firm claims that the modified product, based on a measurement technique pioneered by the company more than 40 years ago, is easier to operate wherever it is needed around the plant. In process control applications, says Land, the Lancom 200 reports concentrations of SO3, generating data that can be used to reduce the volumes of costly additives injected into the fuel before the boiler to reduce downstream SO3 emissions.
Similarly, where additives are used to improve electrostatic precipitator performance, and particular fly ash collection efficiency, Land claims that the analyser can monitor SO3 slip, thus reducing acid aerosol emissions (blue plume). Examples of thermal efficiency include monitoring the temperature of the sulphuric acid dew-point, so that the flue gas temperature can be kept above it to prevent air heater fouling on coal-fired power plants.
Stuart Harris, head of combustion and environmental monitoring, said, “A plant with this safety margin prevents massive long-term plant corrosions and associated maintenance costs. Acid smut and aerosol emissions are amongst the most significant emissions control issues for any plant, with serious environmental consequences if they are not kept in check.”
Illuminated keyboard gets the glow-ahead
UK-based human-machine interface (HMI) manufacturer CKS Holdings has launched a new illuminated keyboard designed for utility applications.
Each key of the CKS Iluminated Kiosk Keyboard can be individually coloured to create a single uniformly coloured keyboard or create a custom layout by mixing colours in any key combination The new keyboards have an operating temperature of between minus 20°C to plus 60°C and are powered from a USB port. CKS Holdings also offers a three-year warranty available on request.
GE launches updated heat balance software
GE Energy has updated its heat balance software for design and simulation of thermal power plants.
GateCycle 6.0 features an enhanced graphical user interface and program database as well as extended modelling capabilities that now cover hydrocarbon-processing plants such as LNG. It also includes software functionality similar to Microsoft Windows, such as easy renaming of models and equipment, copy/paste functionality of single equipment or groups of equipment and the ability to work with and across multiple models simultaneously.
Daniel Heintzelmann, president of GE Energy’s services business, said: “Using GateCycle, engineers can effectively create the optimal plant design by analyzing mass and energy balances at design and off-design conditions. In its long history, GateCycle has always been rated excellent for its accuracy and flexibility.”
