Calders & Grandidge Ltd.

Company:
Calders & Grandidge Ltd, Lincolnshire.
(St. Gobain group of Companies)

Activity: Pressure Treated Timber & Creosote Impregnation

Giving technical boiler advice to the site manager at an exhibition has led to a lengthy relationship between the two companies.

Calders & Grandidge had a split longitudinal seam on their existing stand-by boiler, which resulted in decommissioning and disposal. JBC supplied and installed a fully reconditioned 2’800kg/h oil fired Wee Chieftain steam package boiler in a new boilerhouse.

The design of pipework services and ancillaries to the new boiler were all designed and installed by JBC who over the years have operated a progressive contract to bring the site services up to specification.

JBC prepares both boilers for their annual insurance survey and five year non-destructive test as well as servicing on the oil burner and maintenance on the solid fuel (waste wood chip twin furnace converted from coal) boiler.

Other contracts include the installation of a steam heating system to one of the production shops, maintenance of both boilers and the installation of blowdown facilities and ancillaries and condensate return systems.

Various plant upgrades and improvements in efficiency have continued through the years and include steam trap surveys and recommendations. Changing the steam traps alone saved the company a fortune in energy savings.

Alterations to a condensate receiver and replacement pump sets also contributed toward savings as well as a thermal insulation programme for the whole plant.
