The phrase "ash collection" is correct and usable in written English.
It can be used in contexts related to the gathering or storage of ashes, such as from cremation or the remnants of burned materials.
Example: "After the ceremony, we will have an ash collection to honor the memory of our loved one."
Alternatives: "ash gathering" or "ash retrieval".
One of the ash collection systems was retrofitted with a baghouse (fabric filter) system, collecting a finer fly ash at a cooler flue gas temperature than the plant that has not been reconfigured.
Therefore, the flue gas temperature can be controlled to enhance particle accumulation and improve ash collection efficiency.
Data about the flowability of fly ashes are important for the design of hoppers of fly ash collection equipment and fly ash storage silos.
The results have been used to design an industrial unit for flue-gas conditioning to improve the fly ash collection by the electrostatic precipitator in a 220 MW coal-fired power plant.
With decreasing temperature below the EADT, both the collected ash amount and ash adhesion force rise, and the detected particles size increases, indicating particle accumulation that improves ash collection efficiency.
This paper evaluates experimentally and numerically the influence of different geometrical and operating parameters of a single stage wire-duct electrostatic precipitators (WDEP) on its fly ash collection efficiency.

Also, during eruptions a 25 station ash-collection network is used to evaluate rates of ash accumulation and volumes (Bernard et al. 2013).
For example, since 2007, a group of volcanologists from the Instituto Geofísico de la Escuela Politécnica Nacional de Quito (2012) has installed about 30 ash-collection receptacles around Tungurahua volcano to improve volume estimations of frequent, small-scale tephra emissions (Bustillos and Mothes2010).
Electric agglomeration is a useful method to improve fly-ash particle collection efficiency in traditional electrostatic precipitators (ESPs) by increasing particle diameter and achieving particle pre-charging.
Performance characteristics of the air-blast atomizing spray-column have been evaluated on the basis of the fly-ash (particulates) collection efficiencies within the stability range of the column.
