Steam Boiler Retrofit and Upgrades

Efficient Boiler Upgrades and Refits

We upgrade and refit boilers to extend their lifetime and improve efficiency. Services include:

• Pressure part modifications
• Fuel conversions
• Power uprates
• Heating surface slag prevention
• Turbine cylinder upgrades and associated boiler modifications
• Improved flexibility and load change rates.

Retrofitting for the Future

With our integrated Engineering, Procurement and Construction (EPC) services, the future of your power production facility is in safe hands. We retrofit and upgrade entire systems with complete boiler solutions that maximize the most readily-available fuels, lower costs and decrease emissions.

Retrofit services include:

• Boiler upgrades for efficiency and operational improvements
• Biomass co-firing and conversion
• Combustion systems for primary Nitrogen Oxide (NOx) control or change of fuel
• Secondary NOX control
• Major integrated projects including Carbon Capture & Storage (CCS)

NC to CNC Retrofit and Upgrades

Avvy Group offers converting or retrofitting services of NC to CNC machine. Our NC Retrofit / Upgrade kit is a low-cost alternative to expensive CNC lathes in the market. It is extremely user friendly, easy to maintain and easy to trouble shoot. With this system, you will be able to machine complex shapes and repeat the process to achieve perfect duplicate parts. Also complex shapes which were not possible to machine on conventional lathe are now possible. (ARC, Threading, Steps, Taper Threading, Boring, ID Facing, OD Facing, Parting etc)

Avvy upgrades the existing conventional Lathe to CNC Lathes to enable;

• User friendly controller software representation of job with automatic generation of G-Code with wizards for different operations
• Increased Productivity and faster machining cycles with perfect control of machine
• Increased Accuracy and Superior repeatability
• Automatic Tool changer capability
• Highly configurable controller
• Lower cycle times
• Upgrades to accurate ball screw instead of lead screw on both axis
• Controllable feed rate
• Better surface finish
• Highly accurate AC Drives with belt reduction for higher resolution and accuracy.
• Low power consumption
• No Skilled labour required.

The Kit

The kit includes AC Servo motors, shaft encoder, precision ball screws, bearings, mounting plates, breakout board, cables, power supply, controller cabinet, ups for controller, Mach3 Controller software. Wizards are provided for the following so that machining can be done without the knowledge of G Codes. OD Turning, ID/OD Facing, ID Boring, ID/OD Taper, OD Arc, ID/OD Fillet, OD Groove, OD/ID Threading, Taper
