Burner and Control Panel Upgrade for a Steam Boiler

During a site visit to Koppers Performance Chemicals NZ Tubman Heating Limited identified the steam boiler as critical to the plants operation. Investigation of the burner and control panel found that both pieces of this essential equipment were outdated and in need of upgrading. Tubman Heating suggested that a new fully modulating burner with a built-in modulating pressure controller will provide better performance in both the control of the burn for the boiler and energy use, with increased efficiency.

A CIB E205A was fitted to replace the 24 year old burner that had reached the end of it’s design life along with a new control panel that included a back end temperature limit controller. The E205A burner is equipped with a high performance combustion head that is designed to achieve maximum efficiency when working on natural gas. A by-passing nozzle can reach a turndown ratio of 1:3 with a pressure regulator.

“Thank you for the fantastic job you and your team did over the Christmas / New Year break getting the new burner and control system installed and other required testing all sorted for our boiler. Really appreciate the great job you did and being able to do it during a period when we didn’t need to be operating the boiler so we had no lost production time.”

Extending the life of a steam boiler by upgrading its controls

Old burner removed

During the 3 monthly service at Apparel Masters in Hamilton, a professional laundry and commercial dry cleaner, our technician found that the burner was running inefficiently with the components worn due to age. The control panel parts were brittle and the cabling needed upgrading for both efficiency and safety. Our Senior Service Technician advised the customer to upgrade the burner and control panel to extend the longevity of the boiler.

Newly installed control panel and components

A new control panel with all new components were installed with new cabling from the control panel to the boiler. The newly installed C.I.B Unigas fully modulating E205A natural gas burner is a reliable and economical burner that is widely used in New Zealand. The high-performance combustion head is designed to achieve maximum efficiency when working on natural gas.

The upgrade and annual survey were completed over a weekend to minimise operational disruption for the customer. Apparel Masters in Hamilton shut down on Friday afternoon and steam was provided by Monday morning.
