Binary Effect of Fly Ash and Palm Oil Fuel Ash on Heat of Hydration Aerated Concrete
The binary effect of pulverized fuel ash (PFA) and palm oil fuel ash (POFA) on heat of hydration of aerated concrete was studied. Three aerated concrete mixes were prepared, namely, concrete containing 100% ordinary Portland cement (control sample or Type I), binary concrete made from 50% POFA (Type II), and ternary concrete containing 30% POFA and 20% PFA (Type III). It is found that the tempe...
متن کاملTrash Compaction
Let P be a set of n objects on a square grid. A push is a transformation of P that involves sweeping a horizontal or vertical line by one unit, starting from the hull of P , displacing objects in the direction of the sweep. For example, when pushing to the right, all the leftmost objects are displaced one unit to the right. This in turn displaces other objects further right. Given P , we want t...
متن کاملThermophysical Properties of Ash Deposit on Boiler Heat Exchange Surfaces
A brief overview on boiler tubes ash deposit characterization and thermophysical properties of deposits are given. The structure of an ash deposit on the heat exchange surface of a boiler is usually non-uniform. The thickness of the deposit increases with time and during this process chemical reactions and sintering of ash particles may lead to structural changes. Therefore the thermal conducti...
متن کاملThe Effect of Ash deposition on Tube Heat Transfer
Due to the abundant coal reserves in China, coal is expected to be the most important energy resource in the future. The ash deposition/slagging behavior can obviously affect the heat transfer efficiency of heat transfer tubes in boiler, and cause increasing coal consumption. In order to clarify the effect of ash deposition behavior on heat transfer characteristics of the tube in boiler, a pulv...
متن کامل3617P HYONA - trash
Visual scenes typically contain many objects that compete for the control of attention and saccades, on the basis of their intrinsic salience (exogenous control) or their relevance for the goals of the observer (endogenous control). The present chapter reviews the evidence regarding the relationship between endogenous and exogenous attention and saccades. Furthermore, a competitive integration ...
