Ash is extracted from the reception bins by tubular vibrating feeders and dosed to the coal mill feeding hoppers. Then ash is milled by coal pulverisers along with coal before being injected into the boiler through coal burners. As a result, bottom ash and ECO ash are turned into fly ash, a more valuable by-product of the coal combustion (CCP ...
Nov 25, 2013 There are two methods of ash removal from the bottom of the boiler. Pneumatic vacuum system and a mechanical system. Specially engineered primary crusher splinters large clinkers, and a second stage grinder mill reduces bottom ash to coarse (granular) or fine (powder) sizes, as desired.
HYDROVACTOR vacuum producers and steam jet exhausters provided the required vacuum-induced flows. The hydraulic bottom ash handling system, utilizing the HYDROSEAL pump, dominated the ash handling industry until the introduction of the jet pump which provided improved performance at a lower cost with reduced maintenance.

Advantages. Internal sizing grids trap large material chunks, preventing damage to the pump and allow for easy removal through the access door. Separate mill rejects systems allow for mill rejects to be conveyed intermittently, saving operating costs, and without interfering with bottom ash hopper operation. Request A Brochure.
Bottom ash and boiler slag are both well-draining materials that can be dewatered in 1 or 2 days. Ponded ash, which typically contains fly ash, requires a longer time to dewater, up to two weeks. The higher the percentage of fly ash in ponded ash, the longer the dewatering time. Crushing or Screening.
Fly ash has a high potential to be converted into geopolymeric material due to its abundant supplies and low cost. However, large particle size of the fly ash caused low reactivity which results in low properties of the end product. The improvement on the fly ash properties by mechanical activation allows it as a new possible raw material in wider application besides solving the low reactivity ...
Sep 01, 1999 The strength activity indexes measured on mortars are sufficiently important to allow the use of bottom ash in concrete. When ground for 6 h in a laboratory ball mill, the 28-day strength activity index of bottom ash is increased by 27%.
