An apparatus and method for releasing a filament wound tube (4) from a mandrel (1) utilizing a removable fiber (2) covered with a wrap (3). After a tube is filament wound, the removable fiber (2) is pulled out from beneath the wrap (3) to create a plane of slippage between the mandrel (1) and tube (4) to provide for easy removal.

Apparatus and method to release a filament wound tube from a mandrel

A ceramic element for a sootblower element is disclosed in which the element is manufactured by winding a ceramic fiber around a mandrel and subsequently densifying the composite using a sol-gel process. Separate elements are coupled together using a ceramic coupling member. Ceramic nozzle bodies are inserted into the elements. The sootblower tubes disclosed herein can withstand greater temperatures and more corrosive environments than currently used metallic lance tubes, thus enabling the sootblower element to be permanently installed within a boiler and eliminating the need for a retracting element type sootblower.
