    In the experimental study using a state-of-art ultrasonic technique, erosion magnitudes in two standard 4-inch elbows separated by a distance of 10 pipe diameter have been measured. Experiments have been conducted in single and two-phase flow regimes for different particle sizes and gas and liquid velocities. 39 J. Fan, D. Zhou and K.

      The presence of solid particles in turbomachinery flow affects the component performance as well as its life. The subject of particulated flows can be broadly divided into three parts, namely, particle trajectories, the effect of particles on the aerodynamics of flow and material erosion. Looking into number of proposed and under coal asli prodjuctioa* a such grea-ter research effort is to be devoted to investigate thecharacteristics and uses of coal ash«, Many agricultural lands have been converted into ash disposal yards or affected by erosion of ash* More anabasis' is repaired to find use of coal ash for agricultural.

    The health and environmental impact of the coal industry includes issues such as land use, waste management, water and air pollution, caused by the coal mining, processing and the use of its addition to atmospheric pollution, coal burning produces hundreds of millions of tons of solid waste products annually, including fly ash, bottom ash, and flue-gas desulfurization sludge, that. turbomachinery flows that contain solid particles represent an undesirable yet often inescapable condition because of practical operating considerations. Dust, sand, fly ash, iron oxide, process-originated materials, and the debris from abradable seals or blade rubbing are examples of the varied composition of these solid particles. these particles.

5 June | Journal of Fluids Engineering, Vol.No. 8 Turbomachinery affected by environmental solid particles. The major problem confronting developers of coal burning boilers, fluidized beds, and gas and steam turbines, is the serious erosion of the systems' components by the suspension of fly ash or other.

Coal Ash: Hazardous to Human Health (burned). It includes fly ash (fine powdery particles that are carried up the smoke stack and captured by pollution control devices) as well as coarser materials that fall to the bottom of the furnace.

Most coal ash comes from coal-fired erosion and runoff, and through the air as fine particles or dust. Ash erosion is one factor for pressure parts damage in high ash coal fired boilers and minimizing erosion will extend life of the pressure parts and thereby the availability of the boiler.

As low grade coals are now emerging to be used in large quantity in boilers for power generation and process steam requirement it has become necessary to protect the pressure parts from ash erosion.

This paper deals with the prediction of the particle dynamic and erosion characteristics due to dust ingestion in an axial flow fan, installed in a high bypass-ratio turbofan engine that operates in a dusty environment.

Dynamic behavior comprises the particle trajectory and its impact velocity and location. While the erosion characteristics are resembled by the impact frequency, erosion rate.

Hiorthhamn is an abandoned Norwegian coal mining settlement with a loading dock and a lot of industrial infrastructure left in the coastal zone. In this study, changes in the position of km of the Hiorthhamn shoreline, which affect cultural heritage, is described for a time-period spanning 92 years (–).
