High Concentration Slurry Disposal Accepted at Power Plants

An efficient coal unloading system is the key to the movement of coal rake for optimum utilisation. High Concentration Slurry Disposal (HCSD) systems have proved to be very successful and economic for pumping of ash to the ponds. Belt conveyors and pneumatic conveying systems are an integral part of the power plant for handling of coal and ash.

Introduction and Types Of Thermal Power Plant

INTRODUCTION OF THERMAL POWER PLANT. Thermal power plant or steam power plant is a generating station which converts heat energy of fossile fuels into electrical energy.Generally bituminous,brown or peat type coal are used as the fuel of coal basesd thermal power plant.. In a thermal power palnt, coal is burnt in a big boiler which produces steam at high pressure and temperature.

Power Plants Shifting to Dry Bottom Ash Handling

As a result, power plants have thoroughly analyzed their production processes to find ways to minimize waste, achieve efficiency, promote environmentallyfriend procedures, and cut costs. When it comes to ash handling, that means replacing water with another common medium: air. The result is dry bottom ash
