Biomass cleaning project
26 January 2018
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 all mechanical handling, storage, and out-loading systems, 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 to carry out bulk removal duties or for 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; air passes to the 45kW exhauster package. Products are dispensed via a rotary valve into a screen for separation; solids are sent one way and dust goes 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 pipe work.
