The present invention relates to a touch location detecting panel and, more particularly, to a touch location panel having a plurality of sensing areas arranged two-dimensionally. The ash transport system transports an ash mass from the airlock or hopper valve to the transport line if pressure in the transport line falls below a predefined pressure threshold assigned to the respective airlock or hopper valve. Preferably, at least one of the heteroatoms is nitrogen, which is typically provided as part of a heterocyclic ring. The connector pin includes a first end having an exterior threaded portion and a second end having a connector pin opening. It is combined with other apparatus that remove particulates and byproducts sometimes produced by the NUV source and maintains positive pressure of the confined space so as to prevent the influx of air from outside the protected zone.
