Fuel Handling System BrainKart
Coal handling is part of the larger field of bulk . Material handling, and is a complex and vital part of the CPP. FUEL HANDLING SYSTEM . Coal delivery equipment is one of the major components of plant cost. The Therefore, one of the major requirement of a power plant is to reduce the cost of handling of coal from the point of its origin upto the furnace of boiler where it is burnt. Various steps involved in a coal handling system as shown in Figure A are : Coal delivery. Unloading. Preparation of coal. Transfer of coal. Storage.Coal Handling in Thermal Power Plant Deepakkumar Yadav

Coal and Ash Handling PPT SlideShare
Simple and sound, requiring minimum operations and transportation. 2. No double handling of coal in plant. 3. Handling unit should be centralized to facilitate inspection and maintenance. 4. Electric motors can be used as driver of mechanism. 5. Working parts should be enclosed to avoid abrasion and corrosion.Pulverized coal-fired boiler. A pulverized coal-fired boiler is an industrial or utility boiler that generates thermal energy by burning pulverized coal (also known as powdered coal or coal dust since it is as fine as face powder in cosmetic makeup) that is blown into the firebox. The basic idea of a firing system using pulverised fuel is toPulverized coal-fired boiler

Pulverized coal storage in Bunker and coal handing system
Each type of fuel handling system consists of crushers, magnetic separators, driers, pulverizing mills, storage bins, conveyors and feeders. Figure: Pulverized coal handling plant showing all required equipment for unit and central system. The arrangement of different equipment required in both systems is shown in figure.mixing bins where the various types of coal are stored. The coal is transferred from the mixing bins to the coal crusher where it is pulverized to a preselected size between 0.15 and 3.2 mm (0.006 and 0.13 in.). The desired size depends on the response of the coal to coking reactions and the ultimate coke strength that is required.12.2 Coke Production U.S. Environmental Protection Agency

A Comparison of Three Types of Coal Pulverizers Babcock Power
Properly sized pulverized coal, however, passes into the fan section. In this section, an integral fan wheel, with abrasion-resistant alloy fan blades, transports the pulverized coal from the pulverizer section through the coal pipes to the burners. A typical arrangement of an ATRITA pulverizer system is shown in Figure 3.Proper burning of fuel requires: correct proportion of air, mixing of fuel and air, high temperature and adequate residence time.

Advantages of pulverized coal firing Large surface area per unit mass allows faster and efficient combustion. Less excess air is required for complete combustion Any type of coal can be used Better response to variation in load Large amount of heat release makes it suitable for super thermal power station Carryover of unburnt fuel to ash 3. 2.Coal pulverizer/mill system One of the critical power plant components that is relied upon to convert the energy stored in coal into electricity is the coal pulverizer or mill. The coal flow is controlled by the feeder, allowing coal to flow into the pulverizer mill. The pulverized coal and air mixture is then transport to the boilerCoal mill pulverizer in thermal power plants PPT SlideShare

Modern thermal power plant PPT SlideShare
Modern thermal power plant. 2. Introduction A steam power plant / thermal power plant is using steam as working fluid. A thermal power station is a power plant in which the prime mover is steam driven. Steam is produced in a boiler using coal as fuel and is used to drive the prime mover, namely the steam turbine. Water is heated, turns Industry trends which could increase the probability of fires and explosions in coal pulverizing systems are: l. The increased use of coal by utilities which have no prior pulverized coal experience. 2. The increased use of Fire and Explosion Prevention in Coal Pulverizing Systems
