Major biomass cleaning project

06 October 2017

Quirepace has designed and installed six central vacuum cleaning/bulk removal systems for one of the largest biomass projects in a UK power station conversion.

The systems were designed to cover the whole of the project's mechanical handling, storage and out-loading system, including rail reception, screen house, conveyor gantries, dome loading/out-loading, transfer towers and onward to processing silos.

Each system is sized for two operators using 76mm bore hoses/tools carrying out bulk removal duties or four operators using 51mm hoses/tools for general heavy duty cleaning.

There are hose connection points within the fixed pipe work attached to a filter separator where the product is separated from the conveying air with the air passing on to the 45kW exhauster package. Products are dispensed via a rotary valve into a screen for separation, the solids are sent one way and the dusts into a pneumatic conveying system.

Due to the potentially explosive characteristic of the product, the filter separator is provided with an explosion rupture panel and the rotary valve provides a flame path barrier. 

In total the systems comprise 170 hose connection points over 2.9km of pipework.
